Instant Automated Inference of Perceived Mental Stress through Smartphone PPG and Thermal Imaging
Youngjun Cho, Simon J. Julier, Nadia Bianchi-Berthouze
Background: A smartphone is a promising tool for daily cardiovascular measurement and mental stress monitoring. A smartphone camera-based PhotoPlethysmoGraphy (PPG) and a low-cost…
Automatic Detection of Reflective Thinking in Mathematical Problem Solving based on Unconstrained Bodily Exploration
Temitayo A. Olugbade, Joseph Newbold, Rose Johnson +6
For technology (like serious games) that aims to deliver interactive learning, it is important to address relevant mental experiences such as reflective thinking during problem sol…
Deep Thermal Imaging: Proximate Material Type Recognition in the Wild through Deep Learning of Spatial Surface Temperature Patterns
Youngjun Cho, Nadia Bianchi-Berthouze, Nicolai Marquardt +1
We introduce Deep Thermal Imaging, a new approach for close-range automatic recognition of materials to enhance the understanding of people and ubiquitous technologies of their pro…
RealPen: Providing Realism in Handwriting Tasks on Touch Surfaces using Auditory-Tactile Feedback
Youngjun Cho, Andrea Bianchi, Nicolai Marquardt +1
We present RealPen, an augmented stylus for capacitive tablet screens that recreates the physical sensation of writing on paper with a pencil, ball-point pen or marker pen. The aim…
