Abstract

Pedestrian navigation using a smartglass is more intuitive and easier to use because various information is dis-played directly in the field of view, and there is no need to look down to see the screen. The global positioning system (GPS) is widely used for pedestrian navigation, but its positioning accuracy is significantly degraded in indoors, undergrounds, and the area surrounded by high-rise buildings. Instead, in indoor areas, pedestrian dead reckoning (PDR) can estimate user's current positions using his/her device's sensors. PDR requires no external infrastructure and can be implemented at low cost, but since it estimates relative positions based on its initial position, errors accumulate as the walking distance increases. Reducing the accumulated errors is important in realizing PDR. In this paper, we propose a PDR method to reduce the accumulated errors for pedestrian navigation using smartglasses. When a user wearing a smartglass stops at some point, its downward acceleration value approaches the value of gravity acceleration. By effectively utilizing this property, the proposed method reduces the accumulated errors. Experimental evaluations show the effectiveness of the proposed method.
