Title
Stabilization of Projected Image for Wearable Walking Support System Using Pico-projector
Abstract
In this paper, we propose a concept of real-time walking support system for the elderly who need preventive care. The system presents visual information on the floor by a wearable projector. Moreover, we describe a method to reduce swing of projected images during walking. Such unstability of projected images does not only affect the view ability, but also makes it difficult to present spatial information, such as footstep. An implementation of a stabilizing functionality is presented. The result of a quantitative experiment showed that an error in the projected position was reduced by 48.7%. Additionally, the result of a qualitative evaluation supported the effect of stabilization.
