This paper presents prototypes of a hardware interface that is directed towards possible integration with a Point-of-Care Testing Environment for Neurological Assessment (POCTENA). While the complete system is intended to assist with diagnosis of mild Traumatic Brain Injury (TBI), the focus of this paper is to present designs of necessary hardware that can be used to assess upper-limb motor performance in a point-of-care setting. The hardware interface is expected to facilitate execution of several visuomotor tasks in an attempt to reliably quantify motor deficits. System usability results are shown to corroborate future directions of the POCTENA system.
