Perceptual Crossing with Artificial Eyes

April 14th, 2021 Comments off

PhD thesis by Siti Aisyah Binti Anas

Nowadays, objects are embedded with various sensors, making the objects knowledgeable and smart, gradually reducing users’ need to intervene. As a result, these intelligent objects that work quietly in the background are perceived as passive and reactive objects when interacting with users. The lack of communication between the objects and the users impedes the objects from being smarter and understanding the users’ requirements. Recently, many researchers actively and continuously research to improve the users’ interaction and engagement with the objects. The research objectives are to increase and improve the users’ awareness when interacting and engaging with the objects. Hence, it is essential to design useful feedback or feed-forward methods to indicate the objects’ internal operation state and facilitating communication with engaging users. Another different method, direct manipulation of the objects that exploits the human skills, also enhanced the interaction and engagement between the objects and the users. Looking at that, yet most human-object communication adopts one-directional communication, where the human always acts as the initiator when interacting and engaging with the objects. Thus, it is questionable and remains arguable to understand the objects’ smartness that could initiate and continuously communicate with the users.

Design for Story Sharing: Connect Seniors with their Children

March 25th, 2021 Comments off

PhD Thesis by Cun Li

The world is graying. The worldwide population over age 65 is expected to more than double from 357 million in 1990 to 761 million in 2025. Within the context of the ageing society, social isolation is widespread among older adults. Among all their social relationships, the older adults rank connections with family members second only to health, as the most important area of their lives. Given that one of the most precious characteristics of older adults is their memory of events, people, and places, storytelling could act as an effective way to keep them stay in touch with their children. However, while younger seniors are embracing online social technologies, their parents, many of whom are still living, are neglected in this trend; these non-tech-savvy elders are targeted in this research. Based on the situation described above, the research presented in this thesis attempts to answer the research question: How can interactive technology facilitate intergenerational storytelling, specifically for non-tech-savvy older adults?

A Review of CBT-i Apps

March 22nd, 2021 Comments off

A Review of Digital Cognitive Behavioral Therapy for Insomnia (CBT-I Apps): Are They Designed for Engagement?

There are different ways to deliver Cognitive Behavioral Therapy for Insomnia (CBT-I), of which in-person (face to face) is the traditional delivery method. However, the scalability of in-person therapy is low. Digital Cognitive Behavioral Therapy for Insomnia (dCBT-I) is an alternative and there are tools on the market that are validated in clinical studies. In this paper, we provide a review of the existing evidence-based CBT-I apps and a summary of the published usability-oriented studies of these apps. The goal is to explore the range of interaction methods commonly applied in dCBT-I platforms, the potential impact for the users, and the design elements applied to achieve engagement. Six commercially available CBT-I apps tested by scientifically valid methods were accessed and reviewed. Commonalities were identified and categorized into interactive elements, CBT-I-related components, managerial features, and supportive motivational features. The dCBT-I apps were effectively assisting the users, and the type of interactions promoted engagement. The apps’ features were based on design principles from interactive product design, experience design, online social media, and serious gaming. This study contributes to the field by providing a critical summary of the existing dCBT-I apps that could guide future developers in the field to achieve a high engagement.

ViBreathe: Heart Rate Variability Enhanced Respiration Training for Workaday Stress
Management via an Eyes-free Tangible Interface

Slow breathing guiding applications increasingly emerge, showing promise for helping knowledge workers to better cope with workaday stress. However, standard breathing guidance is non-interactive, with rigid paces. Despite their effects being proved, they could cause respiratory fatigue, or lack of training motivation, especially for novice users. To explore new design possibilities, we investigate using heart rate variability (HRV) data to mediate breathing guidance, which results in two HRV-enhanced guidance modes: (i) responsive breathing guidance and (ii) adaptive breathing guidance. These guidance modes are implemented on a soft haptic interface named “ViBreathe”. We conducted a user test (N = 24), and a one-week field deployment (N = 4) with knowledge workers, to understand the user experience of our design. The HRV-enhanced modes were generally experienced to reduce tiresome and improve engagement and comfort. And Vibreathe showed great potential for seamlessly weaving slow breathing practice into work routines. We thereby summarize related design insights and opportunities.

Less Collective Stress, Better Workspace

January 29th, 2021 Comments off

B2 project by Joost Buining and Yinying Miao

Work-related stress may result in under-performance and absenteeism of office workers. Employees often struggle to pause their work and reflect on their own stress level, resulting in a gap between one’s perceived and one’s actual level of stress. Therefore, there is a need to raise the awareness of office workers about their own stress levels.

To reach this goal, Stressvas is introduced. It is an office interactive installation using motors and projections to represent heart rate variability data, collected by sensors embedded in office chairs. It aims to stimulate a healthier working attitude through a collective visualization of employees’ stress levels. The approaches used are data-enabled design as well as the personal informatics model. By anonymously displaying the differences among colleagues in a team, employees can reflect on their own mental health from a more objective perspective. Therefore, triggering behavior change for a healthier and better workspace.

Exploring Fantasy Play in MathMythos AR

December 22nd, 2020 Comments off

Fostering fantasy play for young children through augmented reality has the potential to support 21st century learning activities by stimulating creativity, communication, and flexibility. We present a design exploration of MathMythos AR, an augmented reality card-based math addition game that enables children to engage in basic math tasks embedded in fantastical narratives. We provide insights into our design process, the effects of fantasy and everyday narratives, and discuss implications for AR card games that show potential to foster motivation for learning math. The presented insights are the foundation for the the next iteration of MathMythos AR, where we aim to create compelling and immersive AR narratives for learning.

Effects of the Level of Interactivity of a Social Robot and the Response of the Augmented Reality Display in Contextual Interactions of People with Dementia

July 30th, 2020 Comments off

The well-being of people with dementia (PWD) living in long-term care facilities is hindered due to disengagement and social isolation. Animal-like social robots are increasingly used in dementia care as they can provide companionship and engage PWD in meaningful activities. While most previous human–robot interaction (HRI) research studied engagement independent from the context, recent findings indicate that the context of HRI sessions has an impact on user engagement. This study aims to explore the effects of contextual interactions between PWD and a social robot embedded in the augmented responsive environment. Three experimental conditions were compared: reactive context-enhanced robot interaction; dynamic context-enhanced interaction with a static robot; a control condition with only the dynamic context presented. Effectiveness evaluations were performed with 16 participants using four observational rating scales on observed engagement, affective states, and apathy related behaviors. Findings suggested that the higher level of interactivity of a social robot and the interactive contextualized feedback helped capture and maintain users’ attention during engagement; however, it did not significantly improve their positive affective states. Additionally, the presence of either a static or a proactive robot reduced apathy-related behaviors by facilitating purposeful activities, thus, motivating behavioral engagement.

Social Glasses: Simulating Interactive Gaze for Visually Impaired People in Face-to-Face Communication

June 9th, 2020 Comments off

Eye contact is crucial in social interactions, linking with sincerity and friendliness. However, blind people cannot see and make eye contact when they communicate with sighted people. It influences the involvement of blind people in blind-sighted conversations. Based on this context, we implemented Social glasses with an eye-tracking system, aiming to improve the communication quality between blind and sighted people in face-to-face conversations. Social glasses attempts to simulate the appropriate gaze for blind people, especially establishing the “eye contact” in blind-sighted conversations. To evaluate the impact of the interactive gaze displayed on the Social glasses, we performed dyadic conversation tests under four experimental conditions (No Gaze, Constant Gaze, Random Gaze, and Interactive Gaze) for 40 participants. Quantitative results showed that the Interactive gaze has a positive impact on improving the communication quality between blind and sighted people, which were consistent with a qualitative analysis of the participants’ comments.

Supporting intergenerational memento storytelling for older adults through a tangible display: a case study

March 21st, 2020 Comments off

Mementoes act as emotional companions that anchor stories. Older adults typically have a rich knowledge of family mementoes. However, storytelling and preservation of mementoes are still problematic for them: their mementoes are still mostly in physical format, which is difficult to share and preserve. Additionally, digital applications and websites for sharing mementoes usually are inaccessible for them. As a result, they spend much time collecting mementoes, but spend less time on telling and recording the related stories. In response to this, we report our study driven by the research questions: Rq1: What are the characteristics of older adults’ intergenerational memento storytelling? And Rq2: In which ways could a tangible display facilitate intergenerational memento storytelling for older adults? We designed a tangible device named Slots-Memento. We first conducted a preliminary evaluation to refine the prototype. In the field study, eight pairs of participants (each pair consisting of an older adult and his/her child) were recruited to use the prototype for around 1 week. Semi-structured interviews were then conducted both with the older adults and their children. Subsequently, mementoes collected were categorized and analyzed. Stories collected were firstly transcribed, then were conducted with structural and interactional analysis. In the concluding discussion, we present abstract implications for the research questions: two tables summarizing characteristics of their intergenerational memento storytelling, and related strategies of designing a tangible display individually.

Enhancing Social Closeness between Drivers by Digital Augmentation

March 14th, 2020 Comments off

Chao Wang, Jacques Terken, Jun Hu, and Matthias Rauterberg

Driving is a social activity: Drivers need to coordinate and cooperate with each other to share the infrastructure. The relationship between drivers influences their driving behavior and experience. Lights, horn and speed are the most frequently used means to exchange information, limiting both the range and the bandwidth of the connectivity and leading to isolation, loneliness, and competition. We present “iSticker” and “MusicHound”, two concepts that aim to establish a connection by presenting similarity information between drivers. The two concepts were prototyped and evaluated with users in a driving simulator. The results showed that iSticker and MusicHound enhance drivers’ social closeness with each other and belongingness during the journey.
