Non-contact Physiological Measurement

As humans are homeothermic, our internal temperature is closely linked with numerous physiological and psychological mechanisms. Given this, human thermal patterns have been explored to improve the understandings of our body for a couple of centuries (Cho, 2019). Researchers have shown that physiological signatures can be captured via non-contact thermal ...

Automatic Recognition of Psychological States (eg. Mental Stress)

With sensing technology becoming pervasive in our everyday life, the ability to monitor human psychological states has become important in human computer interaction. Amongst such states, high level mental stress or mental workload is a common problem affecting mental, physical health and life in our modern society (Nash & Thebarge, ...

Matlab source codes: Stress Induction Tasks for “DeepBreath” [ACII2017]

Source code for "DeepBreath Project" Description: We propose DeepBreath, a deep learning model which automatically recognises people's psychological stress level (mental overload) from their breathing patterns. Using a low cost thermal camera, we track a person's breathing patterns as temperature changes around his/her nostril. The paper's technical contribution is threefold ...

3D modelling files for “RealPen: Providing Realism in Handwriting Tasks on Touch Surfaces using Auditory-Tactile Feedback” [UIST 2016]

Description: 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 is to create a more engaging experience when writing on touch surfaces, such as screens of tablet computers. This is ...
