Interaction with a tele-rehabilitation platform through a natural user interface: A case study of hip arthroplasty patients

Abstract

Using a tele-rehabilitation platform for motor recovery obliges the user to interact at a remote distance from the computer. In such a situation, a natural user interface can be used both to record the therapeutic movements performed by the patient, and to navigate in the web application. Nevertheless, it is necessary to assess the user experience to validate the system usability. The present paper describes an experiment to test the usability of a platform designed to enhance the recovery of patients after hip replacement surgery. The user experience is evaluated through several metrics (completion time and usability questionnaire) and the results are related to a sociodemographic questionnaire. A clustering approach is implemented to identify a relationship between the user’s profile and the interaction performance with the platform.
