Presenting waypoint navigation on a visual display is not suited for all situations. The present experiments investigate if it is feasible to present the navigation information on a tactile display. Important design issue of the display is how direction and distance information must be coded. Important usability issues are the resolution of the display and(More)
The use of the tactile modality is not common in Human Computer Interaction. However, there may be good reasons to do so. For example in situations in which the visual sense is restricted (e.g., in virtual environments lacking a wide field of view, or for the visually handicapped persons), or overloaded (e.g., flying an airplane or driving in an unknown(More)
In this paper, we present three field-based evaluations of a tactile land navigation system. In Experiment 1, we transition from a laboratory setting to rugged terrain used to train US Army soldier land navigation. Navigation in this challenging terrain requires careful attention to one's surroundings. Participants navigated 3 waypoints along 600 meters(More)
This paper describes two aspects of the application of tactile information presentation in the cockpit. The first half of the paper discusses why the tactile channel might be used instead of, or in addition to, the more common visual and auditory channels. It lists several categories of information used in cockpits and explores their appropriateness for(More)
This paper describes the potential of using vibro-tactile displays for automobile drivers. Technological developments in the field of driver support systems and tactile displays, combined with the ever increasing need to enlarge the capacity of the driver's information channel, form the reason to review the possibilities of in-car tactile displays and to(More)
This in-traffic, field study examined the merit of using a car seat instrumented with tactile stimulation elements (tactors) to communicate directional information to a driver. A car seat fitted with an 8 times 8 matrix of tactors embedded in the seat pan was used to code eight different directions (the four cardinal and four oblique directions). With this(More)
We investigated experimentally the feasibility of using a tactile display developed by TNO Human Factors as a wayfinding aide for soldiers in the field. Participants walked ten routes on a open field, each route consisting of six waypoints. The participants used the PeTaNa tactile wayfinding aide on all trials. PeTaNa is a wearable system that presents(More)
