Interactive Vibrotactile Feedback Enhances the Perceived Quality of a Surface for Musical Expression and the Playing
Abstract:
An advanced multi-touch sensor surface aimed at musical expression was recently equipped by the authors with interactive multi-point localized vibrotactile feedback. Using such interface, a subjective assessment was conducted that measured how the presence and type of vibration affect the perceived quality of the device and various attributes related to the playing experience. Two clearly distinct sound settings each with three vibrotactile feedback strategies were tested. At each trial, the task was to play freely while comparing two related setups which used the same sound setting and differed only in the presence/absence of vibration. Independent of the sound setting, as compared to the respective non-vibrating setups, vibrations conveying frequency and amplitude dynamics cues coherent with the player's gesture and/or sonic feedback had the most positive effect. Vibrotactile feedback especially improved the enjoyment of playing and the perceived potential for musical expressivity.
