The technology of immersive virtual reality (iVR) brings new possibilities into the field of psychodiagnostics. It enables 360-degree stereoscopic 3D visualization, provides a high degree of control over a psychological assessment situation, and enables accurate replication of assessment conditions. The stimuli which would be difficult to obtain or would behave unpredictably in objective reality can be created and precisely tuned in iVR. It also enables automatization for calculating results and for adaptive testing, in which case the system integrates the participant’s interim results and modifies the diagnostic situation or the stimuli accordingly. Another advantage is that data such as response time or hand movement can be recorded with high accuracy, which is difficult to achieve in the classic pen-and-paper psychodiagnostics. The aim of this thesis will be to evaluate the current technological options of iVR for psychodiagnostics and to implement an iVR application for an intelligence assessment. The implementation will be done in the Unity game engine and will include

• virtual assessment room inducing calmness but not interfering with user's attention,
• adaptation of the performance subtests from the Wechsler Adult Intelligence Scale (WAIS) for iVR,
• automatization of results calculation, and
• adaptive testing.

The focus will be given on the usability of the application for an intelligence assessment. The thesis will conclude with a simple evaluation of the implemented application, either in a form of a small user study or in a form of a case study comparing the proposed solution to its pen-and-paper counterparts.
