Abstract
This paper investigates the effect of adaptive auditory feedback on continued player performance for stroke patients in a reaction time tablet game. The feedback sound pitch followed a saw-tooth shape that cumulatively increased for fast reaction times and flying back to the base pitch after a single slow reaction time. The analysis was based on data obtained in a field trial with lesion patients during their regular rehabilitation. The auditory feedback events were categorized by feedback type (positive/negative) and the associated pitch change of either high or low magnitude. Both feedback type and magnitude significantly affected on players performance. Negative feedback improved patients reaction times in subsequent hits by 0.42 s and positive feedback impaired their performance by 0.15 s.
