Sensory feedback has been shown to improve the functionality of prosthetic devices in terms of increased control precision. This increase in control is related to the importance of sensory feedback in the context of motor control. To ensure precise control, ideal feedback should be recognized by the user both swiftly and accurately. Transcutaneous electrotactile stimulation is a prevalent choice for providing sensory feedback due to its non-invasive nature. However, it is not yet clear how to optimize this kind of stimulation for speed and accuracy of response. In this study, we set out to investigate how we can affect the Speed-Accuracy Tradeoff (SAT) during responses to an instantaneous change in electrotactile stimulation intensity. Nineteen participants completed an intensity discrimination task. Participants were asked to either prioritize speed or accuracy during specific blocks, while cognitive load, magnitude of intensity shift and direction of shift were manipulated. The results imply that the magnitude of intensity shift needs to be well beyond the just noticeable difference to ensure fast and accurate responses.
