Assessment of surgical performance typically requires that expert evaluators complete structured grading assessments while trainees perform tasks [1]. Objective assessments of surgical task performance based on kinematics of tool movements are gaining traction since they can be automatically computed [2], but many of these metrics are computed after the training tasks are completed. With both approaches, trainees are not provided with real-time performance feedback, and therefore do not gain insight on how to improve task performance or change strategies during training. To overcome this, we introduce a method for the provision of real-time performance feedback through the measurement of SPARC, a frequency-domain measure of movement smoothness. Vibrotactile cues corresponding to SPARC scores are provided through an adjustable bracelet worn on the arm during the task. This provides users insight into their performance as they train in real-time allowing them to adapt their strategies leading to better training outcomes.
