Digital technologies ranging from biosensors to virtual reality have revolutionized the healthcare landscape by offering innovations that hold great promise in addressing the challenges posed by rapidly aging populations. To optimize healthcare experiences for older people, it is crucial to understand their user experience (UX) with digital health technologies. This systematic review, covering articles published from 2013 to 2023, aimed to explore frequently used questionnaires for assessing digital healthcare UX among older people. The inclusion criteria were original studies assessing UX in digital health for individuals aged ≥65 years. Of 184 articles identified, 17 were selected after rigorous screening. The questionnaires used included the System Usability Scale (SUS), the User Experience Questionnaire (UEQ), and the Post-Study System Usability Questionnaire. Customized questionnaires based on models such as the Technology Acceptance Model and the Almere model were developed in some studies. Owing to its simplicity and effectiveness in assessing digital health UX among older people, the SUS emerged as the go-to tool (52.9%). Combining the SUS with the UEQ provided comprehensive insights into UX. Specialized questionnaires were also used, but further research is needed to validate and adapt these tools for diverse cultural contexts and evolving technologies.

This paper deals with a haptic media and video transfer system in which users can touch and move a real object located at a remote place by using haptic interface devices while watching video of the object. Making use of the system, the users can do collaborative work in which the users lift and move the object by holding it between the styluses of the haptic interface devices. In the system, we investigate the influences of inter-stream synchronization error between haptic media and video on the media synchronization quality and the easiness of the collaborative work by subjective assessment. Assessment results show that as the synchronization error increases, the media synchronization quality and the easiness of the collaborative work become worse.
