Usability assessment of natural user interfaces during serious games: Adjustments for dementia intervention

Serious games based rehabilitation program needs a comprehensive and people-centred design for a better efficacy. In most studies benchmarking the computer-interaction interfaces is a prerequisite for adjusting the most appropriate user input for the rehabilitation application. The present study examines a comparison between three natural user interfaces and two standard computer interfaces in two different virtual reality tasks. The results illustrate that the acceptance and user-friendliness of a device regarding the completion of a specific task strongly depends on the task itself and on the abilities of the users
