Neglect App. Usability of a new application for assessment and rehabilitation of neglect

Unilateral Spatial Neglect is one of the most common neuropsychological disorders that can occur after vascular brain accidents. Virtual reality is a new paradigm that showed its effectiveness in clinical setting, enhancing the traditional methods of assessment and rehabilitation. However, usability of a virtual reality system is often undervalued. In this study we present and test the usability of a new mobile virtual reality platform: Neglect App. For the usability evaluation we interviewed four neuropsychologists. The expert showed problems only in five of the fourteen tasks. Only two tasks presented an high (negative) impact on the usability of the application. The results of the SUS showed high levels of usability of our application, both for the assessment and the rehabilitation parts.
