Overview
Abstract
Many studies have shown that robots can provide medical help to patients, such as supporting physical movements, managing mood, or simulating cognitive function. However, robotic cognitive/language assessment, which is vital for mental health care, has not been fully explored and is limited to only a few types of assessment. The aim of this study is to present and evaluate a social robot equipped with a web-based language assessment for Sentence Comprehension Test (SCT) with a dialogue system involving yes/no questions. A total of 50 participants took the test with 36 items conducted by a robot (robot-SCT), while a total of 55 participants took the same test but conducted by a human examiner (human-SCT). Comparative analyses were performed to evaluate the validity of the robot-SCT in terms of test scores and time-related measures. Usability was evaluated through the system usability score and interview feedback. With regard to the validity of the robot-SCT, the test scores indicated no significant differences between the robot-SCT and human-SCT. In addition, conditional differences in reaction time for the test items were observed, similar to the previous paper-and-pencil researches. The high system usability scores (i.e., mean = 78.5, SD = 11) demonstrated the high usability of the robot-SCT. This study demonstrates the validity and usability of robotic language assessment among normal adults. However, further evaluation is required for people with dementia or mild cognitive impairment.
