Learning to play a string instrument takes years of practice. Novice players even find it difficult to play correct pitches, and chromatic tuners that visualize the errors in the played pitches have long been used as an effective aid. However, chromatic tuners can detract users’ visual attention from more essential visual cues such as musical scores. As an alternative, we have been developing HapTune (Haptic Tuner), which conveys the pitch errors to the user using haptic feedback. In this paper, we present an initial design of HapTune that relies on spatiotemporal information coding using two vibrotactile actuators. We also verified that the vibrotactile stimuli provided by HapTune can be easily recognized by a user experiment.
