Introduction: Sensor-feedback systems can be used to support people after stroke during independent practice of gait. The main aim of the study was to describe the user-centred approach to (re)design the user interface of the sensor feedback system “Stappy” for people after stroke, and share the deliverables and key observations from this process. Methods: The user-centred approach was structured around four phases (the discovery, definition, development and delivery phase) which were fundamental to the design process. Fifteen participants with cognitive and/or physical limitations participated (10 women, 2/3 older than 65). Prototypes were evaluated in multiple test rounds, consisting of 2–7 individual test sessions. Results: Seven deliverables were created: a list of design requirements, a personae, a user flow, a low-, medium- and high-fidelity prototype and the character “Stappy”. The first six deliverables were necessary tools to design the user interface, whereas the character was a solution resulting from this design process. Key observations related to “readability and contrast of visual information”, “understanding and remembering information”, “physical limitations” were confirmed by and “empathy” was additionally derived from the design process. Conclusions: The study offers a structured methodology resulting in deliverables and key observations, which can be used to (re)design meaningful user interfaces for people after stroke. Additionally, the study provides a technique that may promote “empathy” through the creation of the character Stappy. The description may provide guidance for health care professionals, researchers or designers in future user interface design projects in which existing products are redesigned for people after stroke.

Game User Research is an emerging field that ties together Human Computer Interaction, Game Development, and Experimental Psychology, specifically investigating the interaction between players and games. The community of Game User Research has been rapidly evolving for the past few years, extending and modifying existing methodologies used by the HCI community to the environment of digital games. In this workshop, we plan to investigate the different methodologies currently in practice within the field as well as their utilities and drawbacks in measuring game design issues or gaining insight about the players' experience. The outcome of the workshop will be a collection of lessons from the trenches and commonly used techniques published in a public online forum. This will extend the discussion of topics beyond the workshop, and serve as a platform for future work. The workshop will be the first of its kind at CHI, tying together HCI research and Game User Research.

In this research, we explored how different variables influence the user experience in the TikTok social media channel. The engagement of the users in giving meaningful feedback to the posts was the main variable being observed. This is important because in several business-to-business and business-to-consumer applications the companies are interested in using meaningful feedback from the users to improve their products, be it a tangible device or a media product. So, instead of focusing on getting more followers, in situations like that, it is more important the kind of feedback received from the users. In this research, a mixed methods approach was applied. Joining the quantitative results with the insights from the qualitative part of the research, it is possible to conclude that the algorithm used by TikTok to define the content in the timelines has a bigger influence on engagement than the kind of content. To achieve the desired result of an increase in the number and quality of feedback by the viewers, it was found that being more direct can produce interesting increases. The posts where the viewers were asked to comment and reply with a certain answer have the most comments. In some instances, the increase is almost 300% more when comparing it to the average amount of comments. Most interviewees also stated that they would love to help out and would provide meaningful feedback if this was directly asked. The same goes for Q&A’s and interaction-based posts.

This poster sketches the outlines of a theoretical research framework to assess whether and on what grounds certain behavioral effects may be attributed to particular game mechanics and game play aspects. It is founded on the Elaboration Likelihood Model of Persuasion (ELM), which is quite appropriate to guide the evaluation structure for interventions that either aim at short term or long term attitude and behavior change.

While Augmented Reality (AR) is increasingly being implemented across a number of industry sectors, an open issue remains over the emotional as well as experiential impacts of this new technology within urban cultural heritage tourism. Therefore, the purpose of this study is to create a tourist experience model for AR tourism applications in the context of urban heritage tourism. The data were collected through five focus groups with a total of 49 participants. A theoretical tourist experience model was generated using Hassenzahl’s [(2003). The thing and I: understanding the relationship between user and product. In M. A. Blythe, K. Overbeeke, A. F. Monk & P. C. Wright (Eds.), Funology (pp. 31–42). Dordrecht: Kluwer Academic Publishers] model of user experience. Hassenzahl's (2003) model relies on the basic idea that product characteristics and features have an effect on the actual consequences. The data were analysed using thematic analysis in order to examine the alignment of themes according to previously identified themes from the literature as well as investigate new emergent themes from the focus groups. This study extends the theoretical aspect of the user experience model by Hassenzahl (2003) through empirical confirmation. The findings reveal that the user experience is formed by the correlation of product features and the perceptions and experiences of tourists. Due to the fact that successful implementation use cases of mobile AR applications is still limited, particularly within the tourism industry, the establishment of a comprehensive set of factors has been considered to be crucial for successful implementation.

Abstract Background Visuospatial neglect (VSN) is a cognitive disorder after stroke in which patients fail to consciously process and interact with contralesional stimuli. Visual Scanning Training (VST) is the recommended treatment in clinical guidelines. At the moment, several mixed reality versions of Visual Scanning Training (VST) are being developed. The aim of this study was to explore the opinions of end-users (i.e., therapists) on the use of Virtual Reality (VR) and Augmented Reality (AR) in VSN treatment. Methods Therapists played one VR and two AR Serious Games, and subsequently flled out a questionnaire on User Experience, Usability, and Implementation. Results Sixteen therapists (psychologists, occupational, speech, and physiotherapists) played the games, thirteen of them evaluated the games. Therapists saw great potential in all three games, yet there was room for improvement on the level of usability, especially for tailoring the games to the patient’s needs. Therapists’ opinions were comparable between VR and AR Serious Games. For implementation, therapists stressed the urgency of clear guidelines and instructions. Discussion Even though VR/AR technology is promising for VSN treatment, there is no one-size-fts-all applicability. It may thus be crucial to move towards a plethora of training environments rather than a single standardized mixed reality neglect treatment. Conclusion As therapists see the potential value of mixed reality, it remains important to investigate the efcacy of AR and VR training tools.

The user’s experience with a recommender system is significantly shaped by the dynamics of user-algorithm interactions. These interactions are often evaluated using interaction qualities, such as controllability, trust, and autonomy, to gauge their impact. As part of our effort to systematically categorize these evaluations, we explored the suitability of the interaction qualities framework as proposed by Lenz, Dieffenbach and Hassenzahl. During this examination, we uncovered four challenges within the framework itself, and an additional external challenge. In studies examining the interaction between user control options and interaction qualities, interdependencies between concepts, inconsistent terminology, and the entity perspective (is it a user’s trust or a system’s trustworthiness) often hinder a systematic inventory of the findings. Additionally, our discussion underscored the crucial role of the decision context in evaluating the relation of algorithmic affordances and interaction qualities. We propose dimensions of decision contexts (such as ‘reversibility of the decision’, or ‘time pressure’). They could aid in establishing a systematic three-way relationship between context attributes, attributes of user control mechanisms, and experiential goals, and as such they warrant further research. In sum, while the interaction qualities framework serves as a foundational structure for organizing research on evaluating the impact of algorithmic affordances, challenges related to interdependencies and context-specific influences remain. These challenges necessitate further investigation and subsequent refinement and expansion of the framework.

Although growing numbers of researchers are studying the role of social engagement in ubiquitous technologies and applications, few frameworks have been proposed that attend to the lived experience of the individual and social dynamic within which it is intimately enmeshed. We present empirical insights using grounded theory from data gathered during a 102-day walk of the second author around Wales. This study inductively developed a substantive social engagement framework of the Walking experience that appears to be simple and flexible. The main aim of this paper is to present the developed framework, where even apparently 'solitary' walking is set within a rich technical and social matrix. The primary characteristics of this framework, namely accuracy of social judgements, accountability of decisions and actions, enhancing self-esteem, and satisfying intrinsic motivation goals, are in line with social user experience and show promise of being useful in ubiquitous technologies, regardless of user activity.

The concept of immersion has been widely used for the design and evaluation of user experiences. Augmented, virtual and mixed-reality environments have further sparked the discussion of immersive user experiences and underlying requirements. However, a clear definition and agreement on design criteria of immersive experiences remains debated, creating challenges to advancing our understanding of immersive experiences and how these can be designed. Based on a multidisciplinary Delphi approach, this study provides a uniform definition of immersive experiences and identifies key criteria for the design and staging thereof. Thematic analysis revealed five key themes – transition into/out of the environment, in-experience user control, environment design, user context relatedness, and user openness and motivation, that emphasise the coherency in the user-environment interaction in the immersive experience. The study proposes an immersive experience framework as a guideline for industry practitioners, outlining key design criteria for four distinct facilitators of immersive experiences–systems, spatial, empathic/social, and narrative/sequential immersion. Further research is proposed using the immersive experience framework to investigate the hierarchy of user senses to optimise experiences that blend physical and digital environments and to study triggered, desired and undesired effects on user attitude and behaviour.

BACKGROUND: Non-use of and dissatisfaction with ankle foot orthoses (AFOs) occurs frequently. The objective of this study is to gain insight in the conversation during the intake and examination phase, from the clients’ perspective, at two levels: 1) the attention for the activities and the context in which these activities take place, and 2) the quality of the conversation. METHODOLOGY: Semi-structured interviews were performed with 12 AFO users within a two-week period following intake and examination. In these interviews, and subsequent data analysis, extra attention was paid to the needs and wishes of the user, the desired activities and the environments in which these activities take place. RESULTS AND CONCLUSION: Activities and environments were seldom inquired about or discussed during the intake and examination phase. Also, activities were not placed in the context of their specific environment. As a result, profundity lacks. Consequently, orthotists based their designs on a ‘reduced reality’ because important and valuable contextual information that might benefit prescription and design of assistive devices was missed. A model is presented for mapping user activities and user environments in a systematic way. The term ‘user practices’ is introduced to emphasise the concept of activities within a specific environment.
