Summary:Ahstract- Light projection-based visual feedback navigation systems are advantageous in easily conveying direction. It also shifts the mental attention of the user from the screen to the environment, which increases safety. However, building an autonomous navigation system for fast navigation using light projection has the challenge of human motion sensitivity and tuning of navigation parameters based on human needs. In this paper, we present an autonomous wearable multiple laser projection stimulus (mLPS) based navigation system. The mLPS consists of three discrete laser lights for representing directional cues. This enables very quick switching for high-speed movements and precise navigation by visual cues. We designed a chest-based wearable suit for minimizing the sensitivity of light projection to human motion. Furthermore, we present a waypoint-based human navigation system and tuning of its navigation parameters based on both navigation performance and perceived human stress. Finally, a successful demonstration of the concept is presented.
