"Tech'' a Deep Breath: Technology-guided Breathing Practise With or Without a Social Robot for Psychological and Emotional Well-Being

Most mental health conditions emerge during adolescence, making university years pivotal for intervention. Nearly 30% of students worldwide experience mental health difficulties, yet support remains constrained by stigma and limited resources. This work investigates how interactive technologies, integrated with a wear…

Initiating the Global AI Dialogues: Laypeople Perspectives on the Future Role of genAI in Society from Nigeria, Germany and Japan

With the rapid development and release of generative AI (genAI) applications, policy discourses primarily take place on an expert level. Little space is given to laypeople - who have to adapt to and adopt the genAI innovations - to share their opinions and experiences. Addressing this gap, we organized 6h/3.5h laypeop…

Predicting Signal Reception Information from GNSS Satellites in Indoor Environments without Site Survey: Towards Opportunistic Indoor Positioning based on GNSS Fingerprinting

Investigating Effect of Altered Auditory Feedback on Self-Representation, Subjective Operator Experience, and Task Performance in Teleoperation of a Social Robot

Teleoperating social robots requires operators to ``speak as the robot,'' as local users would favor robots whose appearance and voice match. This study focuses on real-time altered auditory feedback (AAF), a method to transform the acoustic traits of one's speech and provide feedback to the speaker, to transform the…

Designing a Multisensory VR Game Prototype for Older Adults - the Acceptability and Design Implications

Simultaneous declines in visual function (e.g., dynamic visual acuity), cognitive ability (e.g., cognitive control/multitasking), and physical function (e.g., balance) are major symptoms of aging. Integrating stimulation for those sensory channels into a game could be a suitable way for older adults to engage in long-…

GPS-assisted Indoor Pedestrian Dead Reckoning

Indoor pedestrian dead reckoning (PDR) using embedded inertial sensors in smartphones has been actively studied in the ubicomp community. However, PDR relying only on inertial sensors suffers from the accumulation of errors from the sensors. Researchers have employed various indoor landmarks detectable by smartphone s…

Out for In!: Empirical Study on the Combination Power of Two Service Robots for Product Recommendation

Service robots have increasingly been investigated in retailing. Previous studies mainly focused on the effectiveness of recommendation with regard to a single robot, and whether and how the use of two robots combined can achieve better performance remain unclear. In this study, we address this by exploring the combin…

XR-LIVE: Enhancing Asynchronous Shared-Space Demonstrations with Spatial-temporal Assistive Toolsets for Effective Learning in Immersive Virtual Laboratories

An immersive virtual laboratory (VL) could offer flexibility of time and space, as well as safety, for remote students to conduct laboratory activities through online experiential learning. Recording an instructor’s demonstration inside a VL is an approach that allows students to learn directly from a demonstration. H…

interiqr: Unobtrusive Edible Tags using Food 3D Printing

We present interiqr, a method that utilizes the infill parameter in the 3D printing process to embed information inside the food that is difficult to recognize with the human eye. Our key idea is to utilize the air space or secondary materials to generate a specific pattern inside the food without changing the model g…

Knowledge Graph Completion-based Question Selection for Acquiring Domain Knowledge through Dialogues

Building a perfect knowledge base in a certain domain is practically impossible, so it is effective for dialogue systems to acquire knowledge for enhancing an imperfect knowledge base through natural language dialogues with users. This paper proposes a framework for selecting questions for such knowledge acquisition w…
