![]() The well-trained model was validated using follow-up data (HC group: n=38 MCI group: n=32 and AD group: n=22). To verify the effectiveness of our method, we compared the performance of a well-trained machine learning model using the extracted evaluation index with conventional demographic characteristics and time-related features. The distance between the recorded trajectories and reference was computed as an important evaluation index. First, the model identified a candidate trajectory as the standard answer (template) from the HC group. Among these features, novel template-based features were based on a vector quantization algorithm. Furthermore, we developed an efficient and interpretable cognitive impairment–screening model to automatically analyze cognitive impairment levels that were dependent on demographic characteristics and time-, pressure-, jerk-, and template-related features. In this way, all participants were instructed to perform the TMT-square and circle. A sheet of A4 paper was placed on top of the tablet to maintain the traditional interaction style for participants who were not familiar or comfortable with electronic devices (such as touchscreens). An electromagnetic tablet was used to record each participant’s hand-drawn stroke. Methods: This study included community-dwelling older adult individuals (n=297), who were classified into (1) cognitively healthy controls (HC n=100 participants), (2) participants diagnosed with mild cognitive impairment (MCI n=98 participants), and (3) participants with Alzheimer disease (AD n=99 participants). ![]() Objective: This study aimed to develop and validate a novel Trail Making Test (TMT) using a combination of paper and electronic devices. Particularly, digital sensor technology is a promising detection method.
