Enhanced Presence Evaluation in Virtual Reality Feedback System with TOPSIS Model

Shuo Li et al.

Researcher has been trying to optimize the method for evaluating presence in virtual reality (VR) to address variability and uncertainty in quick evaluations using questionnaires. We recommend using the Technique for Order Performance by Similarity to Ideal Solution (TOPSIS) model to calculate the iGroup Presence Questionnaire to measure users’ overall presence in VR prototyping, instead of the weighted sum approach. The effects of two presence factors (scene density and motion trajectory technology) on a self-developed VR swimming virtual system were tested using the TOPSIS model with 20 participants each 12 tasks in a user experiment. The results were compared using two different weighting methods, fuzzy hierarchical analysis and uniform weighting methods. TOPSIS had a narrower range of data within the 95% confidence interval and a significantly lower coefficient of variation (CV). This indicates enhanced precision in evaluating presence and can be used to compare different technique setting of virtual systems.

Children with Autism Spectrum disorder (ASD) often experience high levels of anxiety and stress. Many children with ASD have difficulty in being aware of their stress and communicating distress to family and caregivers. Stress detection and regulation are vital for their mental well-being. This paper presents a stress-aware pen (ApEn) that detects real-time stress-related behaviors and interacts with users with vibrotactile and light as a feedback indication of interpreted stress levels. ApEn is a context-aware tool for collecting behavioral data related to the expression of stress and can increase users’ stress awareness. A pilot test was conducted with typical developed children to investigate how to detect stress in their daily environment. The pilot test results indicate that ApEn is a promising tool for detecting stress-related behaviors and can attend the user about the detected stress through designed sensory feedback.

Co-constructing Stories Based on Users Lived Experiences to Investigate Visualization Design for Collective Stress Management

Mengru Xue, Pengcheng An, Rong-Hao Liang, Zengrong Guo, Jun Hu, Preben Hansen,
Loe Feijs

Collective stress is the stress within a group or an organization. It affects individuals’ well-being and group productivity. HCI research has started exploring collective stress visualization to facilitate group awareness and collective coping via testing prototypes in controlled settings. However, an in-depth understanding of users’ needs and envisaged scenarios based on their authentic experiences are still lacking. In this study, we utilized a participatory approach called co-constructing stories to investigate how a collective stress visualization would be used in office workers’ authentic workday routines. We constructed use case stories with a group of office workers separately based on their personal lived experiences, using a design probe called AffectiveGarden. Our results categorized six clusters of benefits for collective coping through visualization and their implications for future design practice.

Can blindfolded users replace blind ones in product testing? an empirical study

Shi Qiu, Jun Hu, Ting Han &Matthias Rauterberg

During the design, it is important to evaluate the user experience of representative users in many human product interactions. But, in some cases, it is difficult or even impossible to recruit representative users because they have disabilities that do not allow them to take part in such investigations. Thus, alternative populations are widely studied. The most common way to replace real blind people is to use sighted but blindfolded users when studying design solutions. To test whether such alternative or proxy users can be used to represent blind people in social interactions, we examined the communication quality of 20 blind-sighted pairs and 20 blindfolded-sighted pairs in two different experiments. A prototype named E-Gaze glasses was evaluated as the testing tool. Results clearly show that the blindfolded participants achieved significantly higher communication quality than the blind participants. In qualitative data analysis, the blindfolded participants also reported their user experience of being blindfolded in conversations. Our qualitative results strengthen the conclusion that blindfolded users’ behaviour is different from real blind users’ behaviour. We recommend that blind users should not be substituted for blindfolded users in human product evaluations when communication quality is measured.

Towards the Senior Resident Social Interaction System: A CaseStudy of Interactive Gallery

The number of older adults residing in nursing institutions is increasing, and many of them experience social isolation. The social interaction of older adults constitutes a complex system that involves multiple stakeholders, including fellow residents, caregivers, members of the local community, etc. This paper proposes an Interactive Gallery, comprising a cluster of scenery collectors and an interactive installation resembling a gallery. It aims to promote social interaction among nursing home residents and members of the local community, as well as between senior residents within the nursing home. We conducted a field study that employed behavior observation and semi-structured interviews. Our findings show that the Interactive Gallery had a positive impact on the social interaction of senior participants, and it also stimulated their interest in sharing their experiences with individuals outside of the nursing home. The implications of our field study are significant. We highlight the social interaction system and behavioral characteristics of senior residents, strategies for enhancing social interaction within the nursing home, and strategies for promoting social interaction between senior residents and members of the local community. The Interactive Gallery presents a novel approach to addressing the issue of social isolation among senior residents in nursing homes. Our field study findings demonstrate its potential to improve the quality of life of seniors by promoting social interaction and engagement.

The effect of fantasy on learning and recall of declarative knowledge in AR game-based learning

With increasing research attention on the application of Augmented Reality (AR) and Game elements in education, fantasy elements as imaginary, fictional game features have been shown to improve learners’ motivation and are critical to engaging and immersive experiences in AR game-based learning. With its affordance of enriching real-life education with virtual effects, AR game-based learning has shown its potential to improve recall performance in previous research. However, educators and researchers have concerns regarding the effect of employing fantasy game elements in AR game-based learning, suggesting learning with such elements will add cognitive load for children leading to a lower recall. To explore the effect of AR and fantasy in game-based learning for recalling declarative knowledge, we conducted an experiment involving 98 children participants and 26 adult participants from the Netherlands and China, using our own designed AR game- ChemiKami AR. We used a mixed ANOVA to identify the effect of fantasy and AR on knowledge recall. This study showed that using AR fantasy in game-based learning can improve recall of declarative knowledge and increase learning effectiveness in classroom learning contexts for children. We offer insights and guidelines for designing AR and fantasy experiences that enhance declarative knowledge recall for target groups with different ages, learning capacities, and cultural backgrounds.

Social Balance Ball: Designing and Evaluating an Exergame That Promotes Social Interaction between Older and Younger Players

As the population ages rapidly, there is a strong focus on the healthy aging of older adults. A central part of healthy aging is keeping people connected in later social life. Exergames are recommended as one of the coping strategies to help improve health and quality of life in older adults. In our study, we developed an exergame called Social Balance Ball to engage older and younger people to play together, encouraging social interaction between generations. From May to July 2021, we evaluated this exergame in Shanghai, China, performing a user experiment with 18 unfamiliar young-old pairs under three test conditions (virtual player, mediated human player, and o-located human player). To evaluate the exergame, our main findings demonstrated that participants felt significantly perceived social interaction in mediated play and co-located play than in virtual play. Overall, older participants perceived significantly higher social interaction than younger participants. In this study, we contribute (1) empirical research findings on how the SocialBalance Ball exergame enhances social interaction in generations; (2) design implications for informing future design and development of social exergames
