Summary: Over 1 million children under the age of 17 in the US have been identified with Autism Spectrum Disorder (ASD). These children struggle to recognize facial expressions, make eye contact, and engage in social interactions. Gaining these skills requires intensive behavioral interventions that are often expensive, difficult to access, and inconsistently administered.nWe have developed a system to automate facial expression recognition that runs on wearable glasses and delivers real time social cues, with the goal of creating a behavioral aid for children with ASD that maximizes behavioral feedback while minimizing the distractions to the child. This paper describes the design of our system and interface decisions resulting from initial observations gathered during multiple preliminary trials.

Backtracking Events as Indicators of Usability Problems in Creation-Oriented Applications / Akers, David / Jeffries, Robin / Simpson, Matthew / Winograd, Terry ACM Transactions on Computer-Human Interaction 2012-07 v.19 n.2 p.16

ACM Digital Library Link

Summary: A diversity of user goals and strategies make creation-oriented applications such as word processors or photo-editors difficult to comprehensively test. Evaluating such applications requires testing a large pool of participants to capture the diversity of experience, but traditional usability testing can be prohibitively expensive. To address this problem, this article contributes a new usability evaluation method called backtracking analysis, designed to automate the process of detecting and characterizing usability problems in creation-oriented applications. The key insight is that interaction breakdowns in creation-oriented applications often manifest themselves in backtracking operations that can be automatically logged (e.g., undo and erase operations). Backtracking analysis synchronizes these events to contextual data such as screen capture video, helping the evaluator to characterize specific usability problems. The results from three experiments demonstrate that backtracking events can be effective indicators of usability problems in creation-oriented applications, and can yield a cost-effective alternative to traditional laboratory usability testing.

Undo and erase events as indicators of usability problems Metrics / Akers, David / Simpson, Matthew / Jeffries, Robin / Winograd, Terry Proceedings of ACM CHI 2009 Conference on Human Factors in Computing Systems 2009-04-04 v.1 p.659-668

Keywords: critical incidents, erase, google sketchup, undo, usability testing, user-reported critcial incident technique

ACM Digital Library Link

Summary: One approach to reducing the costs of usability testing is to facilitate the automatic detection of critical incidents: serious breakdowns in interaction that stand out during software use. This research evaluates the use of undo and erase events as indicators of critical incidents in Google SketchUp (a 3D-modeling application), measuring an indicator's usefulness by the numbers and types of usability problems discovered. We compared problems identified using undo and erase events to problems identified using the user-reported critical incident technique [Hartson and Castillo 1998]. In a within-subjects experiment with 35 participants, undo and erase episodes together revealed over 90% of the problems rated as severe, several of which would not have been discovered by self-report alone. Moreover, problems found by all three methods were rated as significantly more severe than those identified by only a subset of methods. These results suggest that undo and erase events will serve as useful complements to user-reported critical incidents for low cost usability evaluation of creation-oriented applications like SketchUp.

Taskposé: exploring fluid boundaries in an associative window visualization Activity-based interaction / Bernstein, Michael S. / Shrager, Jeff / Winograd, Terry Proceedings of the 2008 ACM Symposium on User Interface Software and Technology 2008-10-19 p.231-234

ACM Digital Library Link

Summary: Window management research has aimed to leverage users' tasks to organize the growing number of open windows in a useful manner. This research has largely assumed task classifications to be binary -- either a window is in a task, or not -- and context-independent. We suggest that the continual evolution of tasks can invalidate this approach and instead propose a fuzzy association model in which windows are related to one another by varying degrees. Task groupings are an emergent property of our approach. To support the association model, we introduce the WindowRank algorithm and its use in determining window association. We then describe Taskposé prototype window switch visualization embodying these ideas, and report on a week-long user study of the system.

Improving the accuracy of gaze input for interaction Late breaking results: poster presentations / Kumar, Manu / Klingner, Jeff / Puranik, Rohan / Winograd, Terry / Paepcke, Andreas Proceedings of the 2008 Symposium on Eye Tracking Research & Applications 2008-03-26 p.65-68

Keywords: eye tracking, eye-hand coordination, fixation smoothing, focus points, gaze input, gaze-enhanced user interface design

ACM Digital Library Link

Summary: Using gaze information as a form of input poses challenges based on the nature of eye movements and how we humans use our eyes in conjunction with other motor actions. In this paper, we present three techniques for improving the use of gaze as a form of input. We first present a saccade detection and smoothing algorithm that works on real-time streaming gaze information. We then present a study which explores some of the timing issues of using gaze in conjunction with a trigger (key press or other motor action) and propose a solution for resolving these issues. Finally, we present the concept of Focus Points, which makes it easier for users to focus their gaze when using gaze-based interaction techniques. Though these techniques were developed for improving the performance of gaze-based pointing, their use is applicable in general to using gaze as a practical form of input.

Eyepatch: prototyping camera-based interaction through examples Novel interaction / Maynes-Aminzade, Dan / Winograd, Terry / Igarashi, Takeo Proceedings of the 2007 ACM Symposium on User Interface Software and Technology 2007-10-07 p.33-42

ACM Digital Library Link

Summary: Cameras are a useful source of input for many interactive applications, but computer vision programming is difficult and requires specialized knowledge that is out of reach for many HCI practitioners. In an effort to learn what makes a useful computer vision design tool, we created Eyepatch, a tool for designing camera-based interactions, and evaluated the Eyepatch prototype through deployment to students in an HCI course. This paper describes the lessons we learned about making computer vision more accessible, while retaining enough power and flexibility to be useful in a wide variety of interaction scenarios.

Gaze-enhanced scrolling techniques Wither the GUI / Kumar, Manu / Winograd, Terry Proceedings of the 2007 ACM Symposium on User Interface Software and Technology 2007-10-07 p.213-216

ACM Digital Library Link

Summary: Scrolling is an essential part of our everyday computing experience. Contemporary scrolling techniques rely on the explicit initiation of scrolling by the user. The act of scrolling is tightly coupled with the user's ability to absorb information via the visual channel. The use of eye gaze information is therefore a natural choice for enhancing scrolling techniques. We present several gaze-enhanced scrolling techniques for manual and automatic scrolling which use gaze information as a primary input or as an augmented input. We also introduce the use off-screen gaze-actuated buttons for document navigation and control.

Reducing shoulder-surfing by using gaze-based password entry Passwords / Kumar, Manu / Garfinkel, Tal / Boneh, Dan / Winograd, Terry Proceedings of the 2007 Symposium on Usable Privacy and Security 2007-07-18 p.13-19

Summary: Shoulder-surfing -- using direct observation techniques, such as looking over someone's shoulder, to get passwords, PINs and other sensitive personal information -- is a problem that has been difficult to overcome. When a user enters information using a keyboard, mouse, touch screen or any traditional input device, a malicious observer may be able to acquire the user's password credentials. We present EyePassword, a system that mitigates the issues of shoulder surfing via a novel approach to user input.
With EyePassword, a user enters sensitive input (password, PIN, etc.) by selecting from an on-screen keyboard using only the orientation of their pupils (i.e. the position of their gaze on screen), making eavesdropping by a malicious observer largely impractical. We present a number of design choices and discuss their effect on usability and security. We conducted user studies to evaluate the speed, accuracy and user acceptance of our approach. Our results demonstrate that gaze-based password entry requires marginal additional time over using a keyboard, error rates are similar to those of using a keyboard and subjects preferred the gaze-based password entry approach over traditional methods.

Progressive multiples for communication-minded visualization Collaboration and communication / Phan, Doantam / Paepcke, Andreas / Winograd, Terry Proceedings of the 2007 Conference on Graphics Interface 2007-05-28 p.225-232

ACM Digital Library Link

Summary: This paper describes a communication-minded visualization called progressive multiples that supports both the forensic analysis and presentation of multidimensional event data. We combine ideas from progressive disclosure, which reveals data to the user on demand, and small multiples [21], which allows users to compare many images at once. Sets of events are visualized as timelines. Events are placed in temporal order on the x-axis, and a scalar dimension of the data is mapped to the y-axis. To support forensic analysis, users can pivot from an event in an existing timeline to create a new timeline of related events. The timelines serve as an exploration history, which has two benefits. First, this exploration history allows users to backtrack and explore multiple paths. Second, once a user has concluded an analysis, these timelines serve as the raw visual material for composing a story about the analysis. A narrative that conveys the analytical result can be created for a third party by copying and reordering timelines from the history. Our work is motivated by working with network security administrators and researchers in political communication. We describe a prototype that we are deploying with administrators and the results of a user study where we applied our technique to the visualization of a simulated epidemic.

EyePoint: practical pointing and selection using gaze and keyboard Gaze & eye tracking / Kumar, Manu / Paepcke, Andreas / Winograd, Terry Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007-04-28 v.1 p.421-430

ACM Digital Library Link

Summary: We present a practical technique for pointing and selection using a combination of eye gaze and keyboard triggers. EyePoint uses a two-step progressive refinement process fluidly stitched together in a look-press-look-release action, which makes it possible to compensate for the accuracy limitations of the current state-of-the-art eye gaze trackers. While research in gaze-based pointing has traditionally focused on disabled users, EyePoint makes gaze-based pointing effective and simple enough for even able-bodied users to use for their everyday computing tasks. As the cost of eye gaze tracking devices decreases, it will become possible for such gaze-based techniques to be used as a viable alternative for users who choose not to use a mouse depending on their abilities, tasks and preferences.

GUIDe: gaze-enhanced UI design Interactivity / Kumar, Manu / Winograd, Terry Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007-04-28 v.2 p.1977-1982

ACM Digital Library Link

Summary: The GUIDe (Gaze-enhanced User Interface Design) project in the HCI Group at Stanford University explores how gaze information can be effectively used as an augmented input in addition to keyboard and mouse. We present three practical applications of gaze as an augmented input for pointing and selection, application switching, and scrolling. Our gaze-based interaction techniques do not overload the visual channel and present a natural, universally-accessible and general purpose use of gaze information to facilitate interaction with everyday computing devices.

Gaze-enhanced scrolling techniques Work-in-progress / Kumar, Manu / Winograd, Terry / Paepcke, Andreas Proceedings of ACM CHI 2007 Conference on Human Factors in Computing Systems 2007-04-28 v.2 p.2531-2536

ACM Digital Library Link

Summary: We present several gaze-enhanced scrolling techniques developed as part of continuing work in the GUIDe (Gaze-enhanced User Interface Design) project. This effort explores how gaze information can be effectively used as input that augments keyboard and mouse. The techniques presented below use gaze both as a primary input and as an augmented input in order to enhance scrolling and panning techniques. We also introduce the use of off-screen gaze-actuated buttons which can be used for document navigation and control.

SIDES: a cooperative tabletop computer game for social skills development Displays / Piper, Anne Marie / O'Brien, Eileen / Morris, Meredith Ringel / Winograd, Terry Proceedings of ACM CSCW'06 Conference on Computer-Supported Cooperative Work 2006-11-04 p.1-10

ACM Digital Library Link

Summary: This paper presents a design case study of SIDES: Shared Interfaces to Develop Effective Social Skills. SIDES is a tool designed to help adolescents with Asperger's Syndrome practice effective group work skills using a four-player cooperative computer game that runs on tabletop technology. We present the design process and evaluation of SIDES conducted over six months with a middle school social group therapy class. Our findings indicate that cooperative tabletop computer games are a motivating and supportive tool for facilitating effective group work among our target population and reveal several design lessons to inform the development of similar systems.

Cooperative gestures: multi-user gestural interactions for co-located groupware Gestures and visualizations / Morris, Meredith Ringel / Huang, Anqi / Paepcke, Andreas / Winograd, Terry Proceedings of ACM CHI 2006 Conference on Human Factors in Computing Systems 2006-04-22 v.1 p.1201-1210

ACM Digital Library Link

Summary: Multi-user, touch-sensing input devices create opportunities for the use of cooperative gestures -- multi-user gestural interactions for single display groupware. Cooperative gestures are interactions where the system interprets the gestures of more than one user as contributing to a single, combined command. Cooperative gestures can be used to enhance users' sense of teamwork, increase awareness of important system events, facilitate reachability and access control on large, shared displays, or add a unique touch to an entertainment-oriented activity. This paper discusses motivating scenarios for the use of cooperative gesturing and describes some initial experiences with CollabDraw, a system for collaborative art and photo manipulation. We identify design issues relevant to cooperative gesturing interfaces, and present a preliminary design framework. We conclude by identifying directions for future research on cooperative gesturing interaction techniques.

TeamTag: exploring centralized versus replicated controls for co-located tabletop groupware Interacting with large surfaces / Morris, Meredith Ringel / Paepcke, Andreas / Winograd, Terry / Stamberger, Jeannie Proceedings of ACM CHI 2006 Conference on Human Factors in Computing Systems 2006-04-22 v.1 p.1273-1282

ACM Digital Library Link

Summary: We explore how the placement of control widgets (such as menus) affects collaboration and usability for co-located tabletop groupware applications. We evaluated two design alternatives: a centralized set of controls shared by all users, and separate per-user controls replicated around the borders of the shared tabletop. We conducted this evaluation in the context of TeamTag, a system for collective annotation of digital photos. Our comparison of the two design alternatives found that users preferred replicated over shared controls. We discuss the cause of this preference, and also present data on the impact of these interface design variants on collaboration, as well as the role that orientation, co-touching, and the use of different regions of the table played in shaping users' behavior and preferences.

Benefits of merging command selection and direct manipulation / Guimbretière, François / Martin, Andrew / Winograd, Terry ACM Transactions on Computer-Human Interaction 2005 v.12 n.3 p.460-476

ACM Digital Library Link

Summary: Toolglass [Bier et al. 1993] demonstrated a two-handed command selection technique that combined command selection and direct manipulation. While empirical evaluations showed a speed advantage for ToolGlass, they did not examine the relative importance of two possible factors in its improved performance: (1) the use of two hands and (2) the merging of command selection and direct manipulation.
We conducted a study comparing the relative benefits of three command selection techniques that merge command selection and direct manipulation: one two-handed technique, Toolglass, and two one-handed techniques, namely, control menus [Pook et al. 2000] and FlowMenu [Guimbretière and Winograd 2000]. Participants performed sequences of operations that required both selecting a color and designating the endpoints of a line. Our results show that control menus and FlowMenu are significantly faster than Toolglass. Further analysis suggests that the merging of command selection and direct manipulation is the most important factor in the performance of all three techniques.

Individual audio channels with single display groupware: effects on communication and task strategy Interactions with shared displays / Morris, Meredith Ringel / Morris, Dan / Winograd, Terry Proceedings of ACM CSCW'04 Conference on Computer-Supported Cooperative Work 2004-11-06 p.242-251

ACM Digital Library Link

Summary: We introduce a system that allows four users to each receive sound from a private audio channel while using a shared tabletop display. In order to explore how private audio channels affect a collaborative work environment, we conducted a user study with this system. The results reveal differences in work strategies when groups are presented with individual versus public audio, and suggest that the use of private audio does not impede group communication and may positively impact group dynamics. We discuss the findings, as well as their implications for the design of future audio-based "single display privacyware" systems.

Where the wild things work: capturing shared physical design workspaces Bridging the physical and the digital / Ju, Wendy / Ionescu, Arna / Neeley, Lawrence / Winograd, Terry Proceedings of ACM CSCW'04 Conference on Computer-Supported Cooperative Work 2004-11-06 p.533-541

ACM Digital Library Link

Summary: We have built and tested WorkspaceNavigator, which supports knowledge capture and reuse for teams engaged in unstructured, dispersed, and prolonged collaborative design activity in a dedicated physical workspace. It provides a coherent unified interface for post-facto retrieval of multiple streams of data from the work environment, including overview snapshots of the workspace, screenshots of in-space computers, whiteboard images, and digital photos of physical objects. This paper describes the design of WorkspaceNavigator and identifies key considerations for knowledge capture tools for design workspaces, which differ from those of more structured meeting or classroom environments. Iterative field tests in workspace environments for student teams in two graduate Mechanical Engineering design courses helped to identify features that augment the work of both course participants and design researchers.

Post-cognitivist HCI: second-wave theories Panels / Kaptelinin, Victor / Nardi, Bonnie / Bødker, Susanne / Carroll, John / Hollan, Jim / Hutchins, Edwin / Winograd, Terry Proceedings of ACM CHI 2003 Conference on Human Factors in Computing Systems 2003-04-05 v.2 p.692-693

ACM Digital Library Link

Summary: Historically, the dominant paradigm in HCI, when it appeared as a field in early 80s, was information processing ("cognitivist") psychology. In recent decades, as the focus of research moved beyond information processing to include how the use of technology emerges in social, cultural and organizational contexts, a variety of conceptual frameworks have been proposed as candidate theoretical foundations for "second-wave" HCI and CSCW. The purpose of this panel is to articulate similarities and differences between some of the leading "post-cognitivist" theoretical perspectives: language/ action, activity theory, and distributed cognition.

PointRight: experience with flexible input redirection in interactive workspaces Papers: breaking out of the monitor / Johanson, Brad / Hutchins, Greg / Winograd, Terry / Stone, Maureen Proceedings of the 2002 ACM Symposium on User Interface Software and Technology 2002-10-27 p.227-234

ACM Digital Library Link

Summary: We describe the design of and experience with PointRight, a peer-to-peer pointer and keyboard redirection system that operates in multi-machine, multi-user environments. PointRight employs a geometric model for redirecting input across screens driven by multiple independent machines and operating systems. It was created for interactive workspaces that include large, shared displays and individual laptops, but is a general tool that supports many different configurations and modes of use. Although previous systems have provided for re-routing pointer and keyboard control, in this paper we present a more general and flexible system, along with an analysis of the types of re-binding that must be handled by any pointer redirection system This paper describes the system, the ways in which it has been used, and the lessons that have been learned from its use over the last two years.
