Strength and Limitations
The strength of this study is that (contrary to previous usability studies) it not only directly compares the opinions and demands of HPs and OAs but also provides valuable insights into country- and culture-related differences within both participant groups. Moreover, this study points to future pathways for developing feasible, user-friendly, and enjoyable exergame systems tailored for home settings.A major limitation of this study is that the system could only be tried out once, mainly because of COVID-19 restrictions. Nevertheless, the participants’ feedback indicated that they were able to immerse themselves in the exergame experience and that their expressed opinions were not solely based on their one-time gaming session but also took potential long-term use into account. Future feasibility trials will provide deeper insights into the usability and acceptance of the COCARE system when used over a longer period.
