Keyson, D. V. (1994): Tactile Path Information in User Interface Navigation. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. p. 971.

“Current means of showing a path for movement in graphical user interfaces tend to rely on visual indicators which can be distracting if presented during a task that requires visual attention. In the current study, the use of tactile and combined visual-tactile directional cues as a means for communicating a direction of movement was explored. Tactile, visual, and combined visual-tactile cues were contrasted in their abilities to indicate a direction of movement in a single and dual-task game. In the single task, participants were instructed to rotate a trackball in the indicated direction. In the dual-task a visual search task was performed in addition to the movement task. The tactile cue, compared to the visual cue, reduced movement response times, whereas movement accuracy was sometimes lower. The combined visual-tactile cue produced response times equal to the tactile cue and greater movement accuracy in all conditions. Performance gains using tactile cue information under visual load were attributed to a higher degree of sensory compatibility between a tactile directional cue and a motoric response as opposed to a visual cue and a motoric response. Benefits of game feedback and a simulated task in studying navigational performance using multi-sensory cue information are discussed.”
