Exploring the Usability of Nesplora Aquarium, a Virtual Reality System for Neuropsychological Assessment of Attention and Executive Functioning

Abstract
Virtual reality (VR) has proved to be an efficient alternative to traditional neuropsychological assessment. As VR has become more affordable, it is ready to break out of the laboratory and enter homes and clinical practices. We present preliminary findings from a study designed to evaluate self-reported usability of a VR test for neuropsychological assessment of attention and executive function.

The main objective of the current study was to conduct self reported usability evaluation of Nesplora Aquarium. The sample size was 18 participants aged between 23 and 51 years old (M=29.55; SD=7.12) of which 10 were females (55.6%). First of all, it was carried out Nesplora Aquarium test, and after it, participants completed the System Usability Scale as a measure of self-reported system usability and learnability. The sample rated Nesplora Aquarium as good to excellent. The score rated was 84.16 (SD=12.63) over 100, suggesting that the facility with which people can use this particular tool is between 90 and 95% higher than the rest of the tools. Virtual Reality seems to be a useful and confident in the potential to be used for neuropsychological assessment by clinical practitioners. Beside, this study present a description of Nesplora Aquarium.
