Early screening of mild cognitive impairment (MCI) is important to prevent progression to Alzheimer’s disease. Recent studies have shown that technology-activities of daily living (T-ADL) ability, such as how well older adults use kiosks, is useful in assessing their cognitive impairment. Using virtual reality (VR) and eye tracking technology, an older adult’s T-ADL ability can be quantified through non-invasive eye tracking data. In this context, this study developed a ‘virtual kiosk test’ to assess T-ADL ability through eye tracking data analysis in VR, as a novel method for early screening of MCI. Nine healthy controls and 11 MCI patients were recruited. Subjects performed a virtual kiosk test and neuropsychological tests in a random order. Results showed that MCI patients exhibited worse eye tracking data-lower fixation count (p=0.04) and duration (p=0.03) for the target menu items-when performing the virtual kiosk test compared to healthy controls. A Support vector machine (SVM) using these eye tracking data was able to screen MCI patients with 80.16% accuracy, 72.73% sensitivity, 72.73% precision, and 72.73% F1 score. Our findings demonstrated the effectiveness of the virtual kiosk test to early screen MCI patients.
