- Help-seekers adjust their diction to be more empathic and tactful when they perceive co-workers as stressed.
- Help-seekers experience less negative emotional shifts when rejected by stressed rather than relaxed co-workers, suggesting empathy towards stressed individuals.
- Social messaging applications could boost workplace empathy by enabling stress status sharing, albeit with caution for relaxed status displays.
- For privacy and reduced stigmatization, using subtle haptic vibrations could be considered for signaling users’ negative or sensitive emotional states.

Background: Mediated social touch has been widely studied for remote affective communication in the field of human-computer interaction. Goal: We conducted this literature review to comprehensively understand the state of the art of the designs and evaluations of mediated social touch for mobile devices. Method: We selected 52 articles based on related keywords from four main digital libraries, i.e., ACM, IEEE, Springer, and Scopus. Results: We summarized from these articles how mediated social touch signal is designed, prototyped, and evaluated, and what the main research findings are. Based on the analysis, we identified opportunities for later work.

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.

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.

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.

Engaging people with dementia (PWD) in meaningful activities is the key to promote their quality of life. Design towards a higher level of user engagement has been extensively studied within the human-computer interaction community, however, few extend to PWD. It is generally considered that increased richness of experiences can lead to enhanced engagement. Therefore, this paper explores the effects of rich interaction in terms of the role of system interactivity and multimodal stimuli by engaging participants in context-enhanced human-robot interaction activities. The interaction with a social robot was considered context-enhanced due to the additional responsive sensory feedback from an augmented reality display. A field study was conducted in a Dutch nursing home with 16 residents. The study followed a two by two mixed factorial design with one within-subject variable – multimodal stimuli – and one between-subject variable – system interactivity. A mixed method of video coding analysis and observational rating scales was adopted to assess user engagement comprehensively. Results disclose that when additional auditory modality was included besides the visual-tactile stimuli, participants had significantly higher scores on attitude, more positive behavioral engagement during activity, and a higher percentage of communications displayed. The multimodal stimuli also promoted social interaction between participants and the facilitator. The findings provide sufficient evidence regarding the significant role of multimodal stimuli in promoting PWD’s engagement, which could be potentially used as a motivation strategy in future research to improve emotional aspects of activity-related engagement and social interaction with the human partner.

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.
