Graphical authoring tools for vibrotactile patterns

This paper presents two graphical authoring tools, posVibEditor and VibScoreEditor, developed for the intuitive and convenient design of vibrotactile patterns. The posVibEditor is for the signal-level design and supports drag-and-drop design paradigm, XML data formats, multi-channel timeline interface and internal vibration player. It also includes a module for perceptually transparent rendering that can guarantee the delivery of perceptually correct vibration effects. On the other hand, the VibScoreEditor implements ldquovibrotactile scorerdquo, which is a metaphor of the musical score to vibrotaction for the effective composition of vibrotactile patterns. Another metaphorical feature called vibrotactile clef makes the composition process independent from the process of considering the signal-level characteristics of vibration.
