Abstract: Improved Direction Signalization Technique Employing Vibrotactile Feedback
Tom Vierjahn, Björn Wöldecke, Christian Geiger, and Jens Herder. Improved Direction Signalization Technique Employing Vibrotactile Feedback, 11th Virtual Reality International Conference, VRIC'2009, Laval, France, April, 2009.
Vibrotactile feedback via body-worn vibrating belts
is a common means of direction signalization - e.g.
for navigational tasks. Consequently such feedback
devices are used to guide blind or visually impaired
people but can also be used to support other
wayfinding tasks - for instance, guiding actors in
virtual studio productions. Recent effort has been
made to simplify this task by integrating vibrotactile
feedback into virtual studio applications.
In this work we evaluate the accuracy of an improved
direction signalization technique, utilizing a body-worn
vibrotactile belt with a limited number of
tactors, and compare it to other work. The results
from our user study indicate that it is possible to
signalize different directions accurately, even with a
small number of tactors spaced by 90°.
