Summary: Design patterns were initially proposed in architecture and later
appropriated in software engineering and HCI. Over the years they have proved
to be useful for modelling design experience in these domains. We introduce
patterns for designing distributed user interfaces (DUIs) as an aid for HCI
researchers and practitioners. The patterns are foreseen to work as building
blocks meant for scaffolding the design process. We describe the procedure for
collecting the patterns, as well as the effort undertaken towards development
of a pattern language by identifying relationships between individual patterns
and organising them into a hierarchy. Finally, an overview is given of the
future steps for assessing the expressiveness of this pattern language for
analysing existing and specifying new DUIs.

Summary: In this paper we explore the state of HCI practices in the Nigerian software
industry. Our societies have evolved quickly into an information age, and the
criticality of software and humans as components of socio-technical systems
becomes more worthy to address. In Nigeria, the level of HCI practices is not
yet known. We understand clearly, the role of software systems and services to
strengthen information societies, and we decided to run a survey of the local
software organizations. The results from the survey indicate some level of HCI
awareness. Therefore, we conducted some semi-structured interviews in order to
deepen our understanding of HCI practices in the industry. The results show
there is a knowledge limit regarding HCI practices in the industry. We present
a preliminary report of the results obtained from our studies of software
organizations in Nigeria.

Summary: The information society is expected to use information technologies
extensively. This expectation often results to pressure on the software
industry to develop rapidly, software systems to provide e-services to the
society. Unfortunately, many unusable systems are developed and deployed to the
society in the process. In Estonia, more than 90% of the inhabitants use IT for
various activities, and most government and business services are delivered
through the Internet. Further, the field of human-computer interaction (HCI) is
still very young, and Tallinn University, remains the only institution in the
Baltic zone, running a programme (masters) in HCI. This study presents the
preliminary results of a recently conducted online survey on the extent of
uptake of HCI practices. The outcomes of the study show that awareness and
knowledge of HCI are still very low in the Estonian software industry.

Summary: Although Human-Computer Interaction (HCI) has thrived well in the academia,
its practice, and that of its related fields such as interaction design,
usability engineering, and user experience, has yet to be much appreciated by
software practitioners. This does not help the future of HCI and its related
fields. In order to grasp the gap between HCI in academy and practice, a study
was conducted surveying and interviewing Estonian software industry
representatives. The goal of the study was to depict not only HCI practices but
also to understand what is it that this representatives expect from the field.
The purpose of the study was to develop a master level curriculum with insights
from the industry, that would facilitate the uptake of HCI and its related
fields activities in the local software development industry. The results of
study show that most of the participants are involved with service, system or
software design and these consider that educational programmes in HCI should be
predominantly technical, hands-on, market-oriented with strong input from
abroad. The study also shows that the curriculum should include compulsory
internships, and be either project or course-based.

Summary: Recent studies imply the value of participatory methods in business (Buur et
al., 2008; Roser et al. 2013; Hamid et al., 2011). Participatory design
provides the organizations with the opportunity to share knowledge about users,
deliver innovative products and build competitive advantage. The goal of this
workshop is to explore how insights from user studies might be transferred into
business processes. During the workshop participants will share their
experiences regarding cooperation between the design and business teams and
work on bridging the identified barriers using participatory methods. We aim to
provide a setting where researchers, designers and practitioners will have an
opportunity to gain practical knowledge on applying participatory methods into
business practices.

Summary: It is undoubted that design is of great importance for companies at present.
Therefore, an increasing number of companies decide to align their offerings
with user needs and desires and deliver recognized design values in final
products or services. Nevertheless, the role of business is to deliver
profitable products or services, which bring return on investment as well as
meet other company requirements. Although a high interest in design
deliverables might be distinguished, in practice design values tend to fall
behind business decisions and overall low awareness of user needs can be
observed throughout the company. Finally, there is the gap between the design
and business.
This article describes work in progress aimed at investigating and
systematizing the understanding of the gaps between the design and business. On
the basis of the literature review and conducted interviews it identifies
relevant research gaps and questions that would benefit future scholarly
attention.

Summary: The purpose of this article is to introduce and assess the expressiveness of
a design space for trust-enabling interaction design; or in other words aims to
assess the extent to which the design space can explain/describe trust-enabling
interactions. It starts by situating trust in the domains of Human-Computer
Interaction and Computer-Mediated Interactions.
Then, presents the proposed design space analytical tool. A tool, which
serves for moving away from artifact-centered design to an intentional creation
of value, i.e. support interaction designers on further reflecting on
trust-enabling interactions design values.
These design space's dimensions are rationally derived from the model of
Human-computer Trust, which builds on uses perceived trust. This model has been
previously validated and was also used as a research lens for providing a
greater understanding of how individuals interact with systems, in interaction
processes like openness, knowledge sharing, user's privacy awareness, and
collaboration.
The article concludes with two examples of application through a comparative
inspection of 2 peer-production platforms: Wikipedia and Wordpress. And a
reflection on how the proposed analytical tool can be used as a facilitator for
supporting trust-enabling interaction design processes.

Summary: Many user studies have been conducted to understand the relationship between
interface aesthetics and product's usability. Results of experiment by De
Angeli et al. (2006) show that the link between aesthetics and usability is
more complex than the strong claim -- "What is beautiful is usable".
Interaction has an episodical nature where events follow each other in time and
different stimuli affects users' decisions while completing the task.
This Paper reports the preparation of upcoming user study which will attempt
to explain how aesthetics is influencing quality of interaction. The idea is to
use multiple methods -- usability metrics, psychophysiological metrics
simultaneously with self-reported experience -- and collect data both during
the study and retrospectively.

Summary: The purpose of this paper is to illustrate the use of design space analysis
for structuring the state of the art in a selected domain. The resulting design
space was created based on a literature review and is an analytical tool that
can help interaction designers identify the goals, characteristics, challenges,
enabling technologies, and quality attributes that are relevant to the design
and development of ubiquitous computing systems. This paper describes the
procedure of selecting the design space categories, provides examples of using
the design space, and discusses the limitations and perspective.

Summary: The key aim of introducing information and communication technology (ICT) in
museum settings is to enhance the visitors' experience. However, the concrete
strategies or best practices for digitally augmenting the museums remain to be
determined. The main role of the ICT solutions in a museum context should be
the mediation of the communication between the visitors and the museum
artefacts to support the meaning making process. However, a large number of
existing solutions fail to fulfil this task. In this paper we evaluate two
digital interactive displays in different museums with Semiotic Engineering
methods to detect mismatches between designers' intentions and visitors'
perceptions in this communication process.

Summary: This paper explores the use of semiotic engineering in interaction design
processes. The role of semiotics in HCI has been extensively explored and
evaluation methods have been developed to facilitate the pragmatic application
of semiotics to human-computer interaction. These methods can be applied in
both formative and summative evaluation strategies and, especially when used in
for formative evaluation purposes, they adequately feed back into the design
process. However, with the growing emphasis on co-design, we see the need of
supporting the design process with a frame of reference informed by the
semiotic principles, thus shifting the contribution of semiotics to interaction
design i.e. from an evaluation standpoint to a design decision role. We build
upon a case study to explore the interplay between the semiotic inspection
method and the interaction design process laying the ground for future work in
this direction.

Summary: This paper describes HCI research conducted at Interaction Design Lab of
Institute of Informatics, Tallinn University towards a situated model of
sustainable software appropriation. The overall question of the proposed
research is how to cater for software sustainability by designing for software
appropriation? In this study we are interested to know if and how interaction
design can ensure the sustainability of software solutions by introducing
appropriation signifiers in them that allow users to adapt the software
according to their needs. In the proposed model, users engage in appropriative
behavior that allows the proposed software solutions to evolve through time
while meeting the changing needs of the users. Our paper describes a study
aimed at developing and validating this model situated in the public schools of
Estonia.

Summary: There are no clear instructions for making nice looking visual design.
Beauty depends on many aspects, starting with person who looks at the object
and ending with style, accepted at present moment of time [4]. Absolute truth
can not be revealed, but there exist some guidelines that are called
composition rules [5]. Few talented people create masterpieces intuitively, but
if others follow composition rules, the work will be done attractively as well.
Visual aesthetics of interaction design influences both pragmatic and hedonic
properties of interactive product. Relations between aesthetics and interaction
design have been already well researched and proved, that aesthetic look of
interface adds attractiveness, helps to engage users and will be positively
remembered providing better User Experience (UX). This paper focuses on
establishing connections between visual aesthetics of interface and its
interactive features. The intention of study is to show that aesthetic
interaction design does not only provide better UX but also increases its
pragmatic properties e.g. usability.

Summary: There are many factors that contribute towards good user experience (Roto,
Law, Vermeeren and Hoonhout, 2011). These factors include the content and its
organization, the functionality and features, the information and interaction
design, as well as the visual design (Garett, 2002; Morville's, 2004; and
Hassenzahl, 2005).
This paper builds on the contribution of visual design into user experience
as grounds to tackle the assessment of visual aesthetics evaluation methods.
The intention of the study is to test objective and subjective evaluation
methods with the same objects for comparison. Finding out the correlations
between the objective and subjective evaluation results enables the usage of
computerized image analysis for the purposes of evaluating aesthetics. The work
reported in this paper thus contributes towards identifying a suitable
objective method for a mathematical description of beauty.

Summary: We propose that sustainable interaction design can benefit from the notion
of appropriation-enabling design in the sense that designing for appropriation
can promote renewal and reuse of software and hardware artifacts. To this end,
we establish the relation between sustainable interaction design and
appropriation, identify three appropriation-enabling design challenges, suggest
tentative solutions to them and assess an existing system to illustrate effects
of certain appropriation-enabling design decisions on overall system
sustainability. We propose that the perspective propagated by us can further
HCI paradigms that allow for appropriative interaction, thus helping to sustain
computing resources by promoting the prolonged use of software artifacts. This
approach is based on the assumption that prolonged use of software solutions
will ultimately lead to the longevity of the hardware artifacts on which they
operate.
