We introduce Purrfect Pitch, a system consisting of a wearable haptic device and a custom-designed learning interface for musical ear training. We focus on the ability to identify musical intervals (sequences of two musical notes), which is a perceptually ambiguous task that usually requires strenuous rote training. With our system, the user would...

... also dropped outliers beyond 2í µí¼ (17.2s) -most of these long guess times involved the user asking a question and were not considered a valid trial. Figure 9 shows the mean response time over the course of the study for each condition. We performed another mixed-effect linear regression, modeling the response time based on haptic input, the number of trials, the interaction term, and a random effect for participant ID. ...

Recent progress in imitation learning from human demonstrations has shown promising results in teaching robots manipulation skills. To further scale up training datasets, recent works start to use portable data collection devices without the need for physical robot hardware. However, due to the absence of on-robot feedback during data collection, t...
