This Engineering Doctorate (EngD) research project builds on a 2016 to 2020 research collaboration between Emteq Ltd and BU CDE. CDE Research Engineer Ifigenia Mavridou's research findings show that the Emteq VR technology has significant ability to recognise valence and arousal measurements from participants exposed to affective environments. However, processing signals with different temporal characteristics, and subsequently inferring the affective state of a person based on those signals, is a challenging task. This task requires the development of novel algorithms for event detection and signal synchronisation. Furthermore, the relationship between these objective measures of affective states and the feelings of presence and immersion in the VR environment are not fully understood and further work is required on this topic.
