Voodle utilizes sound symbolic properties of speech for haptic design. Conventionally, the morpheme is considered to be the smallest unit of meaning in language and many natural language interfaces look to understand meaning at the level of the morpheme or word. However, there is evidence of meaning arising from submorphemic aspects of language, such as the form of the speech signal itself. Voodle explores the meaningful relationship between the form of the speech signal and the form of the haptic signal. We investigate how users develop a personal language around a haptic device, what that sounds like, and finally how such a language may be used to facilitate the design of new haptic behaviours.
