Abstract

The aim of this study was to explore the feature pattern of Mild Cognitive Impairment (MCI) in Virtual Reality based Instrumental Activities of Daily Living (VR-IADL) which runs on a tablet PC as well as requires participants a touch interaction to complete the task. Twelve participants (MCI: 4, history of MCI: 2, healthy elderly: 6) were recruited from the region of Philadelphia in USA to perform a VR-IADL task. We found that Non Touch Time (NTT) which is time interval during not touching screen on tablet was longer than that of MCI patients as well as healthy older adults with having history of MCI. Several types of feature patterns were extracted from the NTT such as … Based on the feature pattern, Support Vector Machine (SVM) was performed to calculate the accuracy of the feature patter for characterization of MCI. As the result, the identification rate was 75%.
