Developing tactile feedback for wearable presentation: observations from using a participatory approach

In this paper, we describe a participatory-based approach to developing tactile feedback for a head-mounted device. Three focus groups iteratively designed and evaluated tactile interaction concepts for user-generated use-case scenarios. Results showed productive design insights from the groups regarding approaches to tactile coding schemes addressing the scenario conditions, as well as method-innovations to participatory design techniques for interaction development in unfamiliar sensory modalities such as touch. The study has culminated in the development of a library of tactile icons relating to spatial concepts, which will be tested as part of future work.
