AVEID: Automatic Video System For Measuring Engagement in Dementia

Engagement in dementia is typically measured using behavior observational scales (BOS) that are tedious and involve intensive manual labor to annotate, and are therefore not easily scalable. We present AVEID, a low-cost and easy to use video-based engagement measurement tool to determine the level of engagement of a person with dementia (PwD) when interacting with a target object. We show that the objective behavioral measures computed via AVEID correlate well with subjective expert impressions for the popular MPES and OME BOS, confirming its viability and effectiveness.
