摘要：

Vibro-tactile support for navigation tasks is helpful, not only for visually impaired people. However many different prototypes exist which are not available for experimental usage or commercial ones are expensive. We developed a low-cost prototype of a wristlet and anklet that can easily be rebuild. We evaluated them in a two step procedure with 11 and 10 participants. Both prototypes are easy to use and comfortable to wear. However, the wristlet had a high error rate so that it was not used in the second test. Comparisons between the anklet and voice guidance during navigation in the second test showed the potential of vibration for navigation tasks, but implied a refinement of the design, which will be tested in further studies.
