Going to a Virtual Supermarket: Comparison of Different Techniques for Interacting in a Serious Game for the Assessment of the Cognitive Status

摘要

An increasing number of people suffers from cognitive impairments, also related to aging. Several approaches are used to evaluate the mental status of people affected by cognitive diseases, and there is a growing interest toward approaches that allow a quantitative and personalized evaluation of such impairments. Such approaches comprise serious games and VR-based cognitive assessment systems. Nevertheless, few works attempt to understand how people interact in such systems, and which human-computer interaction modalities are to be preferred when targeting impaired people. The aim of this work is to quantitative and qualitative compare two solutions to play in a virtual supermarket (a PC and a tablet-based solution). The obtained results can be used as a starting point to design VR-based serious games to be used instead of questionnaire-based approaches, thus improving both clinical evaluation performances and patients' motivation.
