Original Kurzfassung:
In this work we propose a wearable solution for boundary
detection (using ultrasonic range finders) and notification (via
tactile actuators) under conditions of poor visibility. ?Personal
Radar? is not ?yet another? belt-like tactile feedback system
used for walking navigation, the unique feature of our obstacle
scanning
and notification solution is, that it is self-contained
and fully self-governed. User studies have confirmed that using
?Personal Radar? can increase safety in close proximity to unseen
obstacles by reducing the movement speed in that region. To
compensate for this speed reduction, studies demonstrated a speed
up
in walking pace in regions distant to obstacles as compared
to subjects moving sightlessly and without technology assistance.
Finally, evaluation revealed that learning increases utilization
performance of the system significantly.
