App Movement: A Platform for Community Commissioning of Mobile Applications Social Media and Location Data / Garbett, Andrew / Comber, Rob / Jenkins, Edward / Olivier, Patrick Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.26-37

ACM Digital Library Link

Summary: There is an increasing demand to encourage inclusivity in the design of digital services. In response to this issue we have created App Movement, a platform that enables the promotion, collaborative design, and deployment of community-commissioned mobile applications. The platform facilitates collaborative customization of a common app template, for which the development and deployment of the app is fully automated. We describe the motivation, design and implementation of App Movement, and report the findings from an 8 month deployment wherein 27 campaigns were created, 11 of which have been successful, and over 1,600 users pledged their support using the platform. We present three case studies to demonstrate its use and adoption in successful and unsuccessful campaigns. We discuss the implications of these studies, including questions of governance (ownership of content, liability of user generated content and moderation), sustainability and the potential to extend App Movement beyond location-based review apps.

Syrian Refugees and Digital Health in Lebanon: Opportunities for Improving Antenatal Health Vulnerable Populations and Technological Support / Talhouk, Reem / Mesmar, Sandra / Thieme, Anja / Balaam, Madeline / Olivier, Patrick / Akik, Chaza / Ghattas, Hala Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.331-342

ACM Digital Library Link

Summary: There are currently over 1.1 million Syrian refugees in need of healthcare services from an already overstretched Lebanese healthcare system. Access to antenatal care (ANC) services presents a particular challenge. We conducted focus groups with 59 refugees in rural Lebanon to identify contextual and cultural factors that can inform the design of digital technologies to support refugee ANC. Previously identified high utilization of smartphones by the refugee population offers a particular opportunity for using digital technology to support access to ANC as well as health advocacy. Our findings revealed a number of considerations that should be taken into account in the design of refugee ANC technologies, including: refugee health beliefs and experiences, literacy levels, refugee perceptions of negative attitudes of healthcare providers, and hierarchal and familial structures.

A Real-Time IVR Platform for Community Radio Vulnerable Populations and Technological Support / Kazakos, Konstantinos / Asthana, Siddhartha / Balaam, Madeline / Duggal, Mona / Holden, Amey / Jamir, Limalemla / Kannuri, Nanda Kishore / Kumar, Saurabh / Manindla, Amarendar Reddy / Manikam, Subhashini Arcot / Murthy, G.

Summary: Interactive Voice Response (IVR) platforms have been widely deployed in resource-limited settings. These systems tend to afford asynchronous push interactions, and within the context of health, provide medication reminders, descriptions of symptoms and tips on self-management. Here, we present the development of an IVR system for resource-limited settings that enables real-time, synchronous interaction. Inspired by community radio, and calls for health systems that are truly local, we developed "Sehat ki Vaani". Sehat ki Vaani is a real-time IVR platform that enables hosting and participation in radio chat shows on community-led topics. We deployed Sehat ki Vaani with two communities in North India on topics related to the management of Type 2 diabetes and maternal health. Our deployments highlight the potential for synchronous IVR systems to offer community connection and localised sharing of experience, while also highlighting the complexity of producing, hosting and participating in radio shows in real time through IVR. We discuss the relative strengths and weaknesses of synchronous IVR systems, and highlight lessons learnt for interaction design in this area.

Challenges for Designing new Technology for Health and Wellbeing in a Complex Mental Healthcare Context Mental Health in Technology Design and Social Media / Thieme, Anja / McCarthy, John / Johnson, Paula / Phillips, Stephanie / Wallace, Jayne / Lindley, Siân / Ladha, Karim / Jackson, Daniel / Nowacka, Diana / Rafiev, Ashur / Ladha, Cassim / Nappey, Thomas / Kipling, Mathew / Wright, Peter / Meyer, Thomas D. / Olivier, Patrick Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.2136-2149

ACM Digital Library Link

Summary: This paper describes the challenges and lessons learned in the experience-centered design (ECD) of the Spheres of Wellbeing, a technology to promote the mental health and wellbeing of a group of women, suffering from significant mental health problems and living in a medium secure hospital unit. First, we describe how our relationship with mental health professionals at the hospital and the aspirations for person-centric care that we shared with them enabled us, in the design of the Spheres, to innovate outside traditional healthcare procedures. We then provide insights into the challenges presented by the particular care culture and existing services and practices in the secure hospital unit that were revealed through our technology deployment. In discussing these challenges, our design enquiry opens up a space to make sense of experience living with complex mental health conditions in highly constrained contexts within which the deployment of the Spheres becomes an opportunity to think about wellbeing in similar contexts.

Expressy: Using a Wrist-worn Inertial Measurement Unit to Add Expressiveness to Touch-based Interactions Touch Interaction / Wilkinson, Gerard / Kharrufa, Ahmed / Hook, Jonathan / Pursglove, Bradley / Wood, Gavin / Haeuser, Hendrik / Hammerla, Nils Y. / Hodges, Steve / Olivier, Patrick Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.2832-2844

ACM Digital Library Link

Summary: Expressiveness, which we define as the extent to which rich and complex intent can be conveyed through action, is a vital aspect of many human interactions. For instance, paint on canvas is said to be an expressive medium, because it affords the artist the ability to convey multifaceted emotional intent through intricate manipulations of a brush. To date, touch devices have failed to offer users a level of expressiveness in their interactions that rivals that experienced by the painter and those completing other skilled physical tasks. We investigate how data about hand movement -- provided by a motion sensor, similar to those found in many smart watches or fitness trackers -- can be used to expand the expressiveness of touch interactions. We begin by introducing a conceptual model that formalizes a design space of possible expressive touch interactions. We then describe and evaluate Expressy, an approach that uses a wrist-worn inertial measurement unit to detect and classify qualities of touch interaction that extend beyond those offered by today's typical sensing hardware. We conclude by describing a number of sample applications, which demonstrate the enhanced, expressive interaction capabilities made possible by Expressy.

Speeching: Mobile Crowdsourced Speech Assessment to Support Self-Monitoring and Management for People with Parkinson's Health Support & Management / McNaney, Róisín / Othman, Mohammad / Richardson, Dan / Dunphy, Paul / Amaral, Telmo / Miller, Nick / Stringer, Helen / Olivier, Patrick / Vines, John Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.4464-4476

ACM Digital Library Link

Summary: We present Speeching, a mobile application that uses crowdsourcing to support the self-monitoring and management of speech and voice issues for people with Parkinson's (PwP). The application allows participants to audio record short voice tasks, which are then rated and assessed by crowd workers. Speeching then feeds these results back to provide users with examples of how they were perceived by listeners unconnected to them (thus not used to their speech patterns). We conducted our study in two phases. First we assessed the feasibility of utilising the crowd to provide ratings of speech and voice that are comparable to those of experts. We then conducted a trial to evaluate how the provision of feedback, using Speeching, was valued by PwP. Our study highlights how applications like Speeching open up new opportunities for self-monitoring in digital health and wellbeing, and provide a means for those without regular access to clinical assessment services to practice and get meaningful feedback on their speech.

ResViz: Politics and Design Issues in Visualizing Academic Metrics Visualization Methods and Evaluation / Elsden, Chris / Mellor, Sebastian / Olivier, Patrick / Wheldon, Pete / Kirk, David / Comber, Rob Proceedings of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.1 p.5015-5027

ACM Digital Library Link

Summary: The use of data and metrics on a professional and personal level has led to considerable discourse around the performative power and politics of 'big data' and data visualization, with academia being no exception. We have developed a university system, ResViz, which publicly visualizes the externally funded research projects of academics, and their internal collaborations. We present an interview study that engages 20 key stakeholders, academics and administrators who are part of the pilot release for the first version of this system. In doing so, we describe and problematize our design space, considering the implications of making metrics visible and their social use within a large organization. Our findings cut across the way people communicate, review and manage performance with metrics. We raise seven design issues in this space -- practical considerations that expose the tensions in making metrics available for public contestation.

Video Showcase: Using Expressy to Showcase Expressiveness in Touch-based Interactions Video Showcase Presentations / Wilkinson, Gerard / Green, David Philip / Wood, Gavin / Kharrufa, Ahmed / Hook, Jonathan / Pursglove, Bradley / Haeuser, Hendrik / Hammerla, Nils Y. / Hodges, Steve / Olivier, Patrick Extended Abstracts of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.2 p.11

ACM Digital Library Link

Summary: We present a video demonstration of how information about hand movements, generated from a wrist-worn IMU (inertial measurement unit), can be used to provide expressiveness to touch-based interactions. The IMU identifies features that were not previously accessible, such as instantaneous force, wrist roll and pitch. We demonstrate a range of applications that have been extended using Expressy, a system we describe in more detail in the full paper [1]. Tap force allows users to express their intent behind an interaction before touch. Wrist roll and pitch enriches the touch during the interaction. Flick force and wrist roll allows users to follow-up their touch interaction.

Refugees and HCI SIG: The Role of HCI in Responding to the Refugee Crisis SIG Meetings / Talhouk, Reem / Ahmed, Syed Ishtiaque / Wulf, Volker / Crivellaro, Clara / Vlachokyriakos, Vasilis / Olivier, Patrick Extended Abstracts of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.2 p.1073-1076

ACM Digital Library Link

Summary: The recent refugee crisis has escalated and expanded in to a global challenge. In their flight from hostility, refugee populations face challenges in accessing services that are often compounded by political and social tensions. The urgency and complexity of the situation calls for HCI researchers to contribute to the management of this crisis. This SIG aims to bring to the surface the challenges faced by refugees and elicit the experiences of the authors. It also calls for forming a collaborative network of researchers that have an interest in innovatively addressing issues surrounding refugee populations.

Digital Civics: Citizen Empowerment With and Through Technology SIG Meetings / Vlachokyriakos, Vasillis / Crivellaro, Clara / Dantec, Christopher A. Le / Gordon, Eric / Wright, Pete / Olivier, Patrick Extended Abstracts of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.2 p.1096-1099

ACM Digital Library Link

Summary: The current economic crisis has thrown the relationship between citizens, communities and the state into sharp relief. Digital Civics is an emerging cross-disciplinary area of research that seeking to understand the role that digital technologies can play in supporting relational models of service provision, organization and citizen empowerment. In particular, how digital technologies can scaffold a move from transactional to relational service models, and the potential of such models to reconfigure power relations between citizens, communities and the state. Through examples of Digital Civics systems. that question conventional models of service provision, this SIG aims to bring together researchers and practitioners to critically discuss and explore the theoretical underpinnings, development and deployment of digital tools, platforms and processes within a Digital Civics research agenda.

Everyday Surveillance Workshop Summaries / Briggs, Pam / Churchill, Elizabeth / Levine, Mark / Nicholson, James / Pritchard, Gary W. / Olivier, Patrick Extended Abstracts of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.2 p.3566-3573

ACM Digital Library Link

Summary: Surveillance, literally the 'close watching over' of a person or a group, was historically carried out to monitor adversaries and criminals. The digital era of sensor-rich, connected devices means that new forms of everyday surveillance -- what some are calling 'dataveillance' -- are emerging. These are changing the power structures that link people, businesses and governments. In this multidisciplinary, one day workshop, we seek to rethink and understand everyday surveillance practices, asking: what are new forms of surveillance that accompany developments in Big Data and the emerging Internet of Things; what are the anticipated and unanticipated effects of a surveillance culture; how does surveillance need to be (re)configured in order to empower the citizen or contribute to social good? We will ask who "owns" the data that arises from these everyday acts of surveillance and what can result from rethinking these ownership models. We will consider the role and place of research in surveillance data collection and analysis.

Interactivity: Using Expressy to Demonstrate Expressiveness in Touch-based Interactions Interactivity Demos / Wilkinson, Gerard / Wood, Gavin / Hook, Jonathan / Nappey, Tom / Kharrufa, Ahmed / Pursglove, Bradley / Haeuser, Hendrik / Hammerla, Nils Y. / Hodges, Steve / Olivier, Patrick Extended Abstracts of the ACM CHI'16 Conference on Human Factors in Computing Systems 2016-05-07 v.2 p.3800-3803

ACM Digital Library Link

Summary: We present an interactivity demonstration of Expressy. A system that augments existing touchscreen devices with a variety of continuous expressive interaction capabilities, using movement data from a wrist-worn IMU. Our demonstration comprises a set of applications that show how the expressive touch interaction capabilities, offered by Expressy, can enable intuitive and meaningful interactions, in contexts including productivity, entertainment and lifestyle apps. This demo submission accompanies a full paper, describing a conceptual model of expressive touch interaction and the implementation and evaluation of Expressy.

Evaluating Digital Tabletop Collaborative Writing in the Classroom HCI for Education / Heslop, Philip / Preston, Anne / Kharrufa, Ahmed / Balaam, Madeline / Leat, David / Olivier, Patrick Proceedings of IFIP INTERACT'15: Human-Computer Interaction, Part II 2015-09-14 v.2 p.531-548

Summary: We present an evaluation of an "in the wild" classroom deployment of Co-located Collaborative Writing (CCW), an application for digital tabletops. CCW was adapted to the classroom setting across 8 SMART tables. Here, we describe the outcomes of the 6 week deployment with students aged 13-14, focussing on how CCW operated as a tool for learning within a classroom environment. We analyse video data and interaction logs to provide a group specific analysis in the classroom context. Using the group as the unit of analysis allows detailed tracking of the group's development over time as part of scheme of work planned by a teacher for the classroom. Through successful integration of multiple tabletops into the classroom, we show how the design of CCW supports students in learning how to collaboratively plan a piece of persuasive writing, and allows teachers to monitor progress and process of students. The study shows how the nature and quality of collaborative interactions changed over time, with decision points bringing students together to collaborate, and how the role of CCW matured from a scaffolding mechanism for planning, to a tool for implementing planning. The study also showed how the teacher's relationship with CCW changed, due to the designed visibility of groups' activities, and how lesson plans became more integrated utilizing the flexibility of the technology. These are key aspects that can enhance the adoption of such technologies by both students and teachers in the classroom.

Using IMUs to Identify Supervisors on Touch Devices HCI for Education / Kharrufa, Ahmed / Nicholson, James / Dunphy, Paul / Hodges, Steve / Briggs, Pam / Olivier, Patrick Proceedings of IFIP INTERACT'15: Human-Computer Interaction, Part II 2015-09-14 v.2 p.565-583

Summary: In addition to their popularity as personal devices, tablets, are becoming increasingly prevalent in work and public settings. In many of these application domains a supervisor user -- such as the teacher in a classroom -- oversees the function of one or more devices. Access to supervisory functions is typically controlled through the use of a passcode, but experience shows that keeping this passcode secret can be problematic. We introduce SwipeID, a method of identifying supervisor users across a set of touch-based devices by correlating data from a wrist-worn inertial measurement unit (IMU) and a corresponding touchscreen interaction. This approach naturally supports access at the time and point of contact and does not require any additional hardware on the client devices. We describe the design of our system and the challenge-response protocols we have considered. We then present an evaluation study to demonstrate feasibility. Finally we highlight the potential for our scheme to extend to different application domains and input devices.

Comparing Fatigue When Using Large Horizontal and Vertical Multi-touch Interaction Displays Touch and Haptic / Al-Megren, Shiroq / Kharrufa, Ahmed / Hook, Jonathan / Holden, Amey / Sutton, Selina / Olivier, Patrick Proceedings of IFIP INTERACT'15: Human-Computer Interaction, Part IV 2015-09-14 v.4 p.156-164

Summary: We report on a user study that compared muscle fatigue experienced when using a large multi-touch display in horizontal and vertical configurations over a one-hour period. Muscle fatigue is recognized as the reduction in a muscle's capacity to generate force or power output and was measured objectively and subjectively before and after a puzzle-solving task. While subjective measures showed a significant level of overall arm muscle fatigue after the task for both configurations, objective measures showed a significant level of muscle fatigue on the middle deltoids and the non-dominant extensor digitorum for the vertical configuration only. We discuss the design implications of these findings and suggest relevant future areas of investigation.

Dancing with horses: automated quality feedback for dressage riders Interacting with animals and flying robots / Thompson, Robin / Kyriazakis, Ilias / Holden, Amey / Olivier, Patrick / Plötz, Thomas Proceedings of the 2015 International Conference on Ubiquitous Computing 2015-09-07 p.325-336

ACM Digital Library Link

Summary: The sport of dressage has become very popular not only amongst professional athletes but increasingly also for private horse owners. In well-defined tests, rider and horse execute movements, which demonstrate the strength, endurance, and dexterity of the animal as well as the quality of the interaction between rider and horse. Whilst at a professional level intensive expert coaching to refine the skill set of horse and rider is standard, such an approach to progression is not usually viable for the large amateur population. In this paper we present a framework for automated generation of quality feedback in dressage tests. Using on-body sensing and automated measurement of key performance attributes we are able to monitor the quality of horse movements in an objective way. We validated the developed framework in a large-scale deployment study and report on the practical usefulness of automatically generated quality feedback in amateur dressage.

Beyond activity recognition: skill assessment from accelerometer data Skills development / Khan, Aftab / Mellor, Sebastian / Berlin, Eugen / Thompson, Robin / McNaney, Roisin / Olivier, Patrick / Plötz, Thomas Proceedings of the 2015 International Conference on Ubiquitous Computing 2015-09-07 p.1155-1166

ACM Digital Library Link

Summary: The next generation of human activity recognition applications in ubiquitous computing scenarios focuses on assessing the quality of activities, which goes beyond mere identification of activities of interest. Objective quality assessments are often difficult to achieve, hard to quantify, and typically require domain specific background information that bias the overall judgement and limit generalisation. In this paper we propose a framework for skill assessment in activity recognition that enables automatic quality analysis of human activities. Our approach is based on a hierarchical rule induction technique that effectively abstracts from noise-prone activity data and assesses activity data at different temporal contexts. Our approach requires minimal domain specific knowledge about the activities of interest, which makes it largely generalisable. By means of an extensive case study we demonstrate the effectiveness of the proposed framework in the context of dexterity training of 15 medical students engaging in 50 attempts of surgical activities.

Social Media As a Resource for Understanding Security Experiences: A Qualitative Analysis of #Password Tweets Authentication Experience / Dunphy, Paul / Vlachokyriakos, Vasilis / Thieme, Anja / Nicholson, James / McCarthy, John / Olivier, Patrick Proceedings of the 2015 Symposium on Usable Privacy and Security 2015-07-22 p.141-150

Summary: As security technologies become more embedded into people's everyday lives, it becomes more challenging for researchers to understand the contexts in which those technologies are situated. The need to develop research methods that provide a lens on personal experiences has driven much recent work in human-computer interaction, but has so far received little focus in usable security. In this paper we explore the potential of the micro blogging site Twitter to provide experience-centered insights into security practices. Taking the topic of passwords as an example, we collected tweets with the goal to capture personal narratives of password use situated in its context. We performed a qualitative content analysis on the tweets and uncovered: how tweets contained critique and frustration about existing password practices and workarounds; how people socially shared and revoked their passwords as a deliberate act in exploring and defining their relationships with others; practices of playfully bypassing passwords mechanisms and how passwords are appropriated in portrayals of self. These findings begin to evidence the extent to which passwords increasingly serve social functions that are more complex than have been documented in previous research.

Designing for mental wellbeing: towards a more holistic approach in the treatment and prevention of mental illness Ageing, health and wellbeing / Thieme, Anja / Wallace, Jayne / Meyer, Thomas D. / Olivier, Patrick Proceedings of the 2015 British Human Computer Interaction Conference 2015-07-13 p.1-10

ACM Digital Library Link

Summary: To date, HCI for mental health has primarily responded to challenges in the treatment of mental illness, with a focus on therapy access and engagement. However, approaches to improving and protecting people's mental wellbeing have received less attention. Prompted by recent discussions in Western Healthcare and Psychology, we argue for a more holistic approach to promoting mental health that expands the field's focus to include strategies for enhancing mental wellbeing. A closer consideration of mental wellbeing can increase the effectiveness of mental health interventions, help in preventing mental illness and relapse, and extend our knowledge as to how we can support people to flourish as individuals and enhance their quality of life more generally. Our aim is to encourage more research on positive aspects of mental health in the treatment and care provision of people with mental health problems, and to support preventive approaches. To this end, the paper provides a comprehensive definition of mental wellbeing as positive emotional, psychological and social health; presents a review of HCI literature illustrating how the field is beginning to respond to the mental wellbeing agenda; and proposes avenues for future design and research in this area.

CueS: cueing for upper limb rehabilitation in stroke Ageing, health and wellbeing / Holden, Amey / McNaney, Róisín / Balaam, Madeline / Thompson, Robin / Hammerla, Nils / Ploetz, Thomas / Jackson, Dan / Price, Christopher / Brkic, Lianne / Olivier, Patrick Proceedings of the 2015 British Human Computer Interaction Conference 2015-07-13 p.18-25

ACM Digital Library Link

Summary: Upper limb weakness is one of the most distressing, long-term consequences of stroke and can be difficult to rehabilitate due to an overreliance on the opposing limb in everyday life. Previous studies have shown potential for cueing to improve upper limb rehabilitation, although these have been conducted in clinical settings. In this paper we describe CueS, a wrist worn cueing device which prompts the wearer to move their upper limb more frequently in their day to day lives. We conducted two, week-long 'in the wild' deployments of CueS with seven participants to obtain reflections and experiences around using the device. All participants reported increased general activity levels from wearing CueS and objective data showed increased levels of activity following cue provision. We reflect upon the potential of wearable cueing devices for upper limb rehabilitation after stroke.

MyRun: balancing design for reflection, recounting and openness in a museum-based participatory platform Designing for reflection II / Clarke, Rachel / Vines, John / Wright, Peter / Bartindale, Tom / Shearer, John / McCarthy, John / Olivier, Patrick Proceedings of the 2015 British Human Computer Interaction Conference 2015-07-13 p.212-221

ACM Digital Library Link

Summary: Cultural organisations are increasingly looking towards using digital technologies to supplement, augment and extend visitors' experiences of exhibits and museums. In this paper, we describe the design and evaluation of MyRun, a 'participatory platform' for a museum. Our goal with MyRun was to use experience-centered design principles of reflecting, recounting and openness as a basis for engaging visitors in sharing stories about experiences related to a nationally significant cultural event. We undertook a qualitative evaluation of the system based upon observations of its use, the contributions visitors made to the platform, and interviews with 10 visitors. We discuss how visitors approached MyRun, contributed and browsed stories, and the challenges associated with the expectations visitors and curators placed on cultural exhibits. We close by identifying a series of design opportunities for future participatory platforms in museum settings.

Exploring Gesture Sonification to Support Reflective Craft Practice What do I hear? Communicating with Sound / Smith, Thomas / Bowen, Simon J. / Nissen, Bettina / Hook, Jonathan / Verhoeven, Arno / Bowers, John / Wright, Peter / Olivier, Patrick Proceedings of the ACM CHI'15 Conference on Human Factors in Computing Systems 2015-04-18 v.1 p.67-76

ACM Digital Library Link

Summary: Much of the knowing employed in skilled craft practice is difficult to communicate solely through written or verbal description. Consequently, the reflection and development of a craft practice in this manner may miss important nuances of practitioners' skills and experiences. We created digital technologies to sonify (using audio to perceptualize data) a group of craft practitioners' gestures to explore how we can aid their reflection in and on their craft, and consequently develop it. Over a number of workshops, the design of these sonifications were iterated based on how the practitioners responded to them. We found that direct sonification of gesture (sounds generated directly from motion sensor data) helped practitioners understand and reflect upon their own and each other's practice, encouraged discussion and enabled modification of craft technique.

LApp: A Speech Loudness Application for People with Parkinson's on Google Glass Making & Sharing Assistive Technologies / McNaney, Roisin / Poliakov, Ivan / Vines, John / Balaam, Madeline / Zhang, Pengfei / Olivier, Patrick Proceedings of the ACM CHI'15 Conference on Human Factors in Computing Systems 2015-04-18 v.1 p.497-500

ACM Digital Library Link

Summary: Reduced vocal volume in Parkinson's is extremely common and can have significant social and emotional impact. We describe the development and evaluation of LApp -- an application for Google Glass to help people with Parkinson's (PwP) monitor their speech volume and cue themselves to speak louder when necessary. Our findings highlight enthusiasm for using the application both at home as a volume training tool and in public social settings as a situated cueing device. We contribute insights to the literature on how eyewear technologies can provide assistance to people with health conditions and offer insights for the design of future self-monitoring and management applications on Google Glass.

Designing for and with People with Parkinson's: A Focus on Exergaming Making & Sharing Assistive Technologies / McNaney, Roisin / Balaam, Madeline / Holden, Amey / Schofield, Guy / Jackson, Daniel / Webster, Mary / Galna, Brook / Barry, Gillian / Rochester, Lynn / Olivier, Patrick Proceedings of the ACM CHI'15 Conference on Human Factors in Computing Systems 2015-04-18 v.1 p.501-510

ACM Digital Library Link

Summary: Parkinson's is a complex and multifaceted condition with a myriad of symptoms, thus, designing for and with this user group requires careful consideration. We reflect upon two studies, employing different design methodologies, relating to the design of rehabilitative exergames in Parkinson's. The first explored the concept of designing 'for' People with Parkinson's (PwP) and focused on specifications outlined by clinical stakeholders. The second used a designing 'with' approach and modified a pre-established participatory design method for use with PwP. We call attention to the importance of carrying out design work with PwP and contribute; an empathic understanding of living with Parkinson's, a set of recommendations for how to design with PwP and a set of wider considerations for developing rehabilitative exergames for PwP.

Your Money's No Good Here: The Elimination of Cash Payment on London Buses The Value of Things / Pritchard, Gary / Vines, John / Olivier, Patrick Proceedings of the ACM CHI'15 Conference on Human Factors in Computing Systems 2015-04-18 v.1 p.907-916

ACM Digital Library Link

Summary: As digital payments become increasingly important features of economic exchange, traditional forms of payment such as cash are becoming phased out in certain settings. We study one such context-the elimination of cash payment on London buses in July 2014. We conducted ethnographic fieldwork, interviews with drivers and collected online and social media comments before, during and shortly after the introduction of cashless fares. We explore how drivers and passengers were fearful of the change due in part to a lack of information and communication, the anticipation of negative effects on vulnerable passengers and a compromise in freedom, flexibility and surveillance. We highlight the ways cashless payments can alter the social function of money, create new forms of work for drivers and passengers, and if not carefully introduced can cause emotional stress and fears of state surveillance and control.
