Graphical Manipulation of Human's Walking Direction with Visual Illusion

SIGGRAPH 2016 Emerging Technologies 2016
Conventional research on pedestrian navigation systems has explored the possibilities of presenting information to users both visually and aurally. Existing navigation systems require users to recognize information, and then to follow directions as separate, conscious processes, which inevitably require attention to the system. This study proposes a novel method that enables pedestrians to be guided without conscious interaction with a navigational system. In this study, we employed a combination of an HMD and a stereo camera for pedestrian control. This system, displaying images as if the HMD were transparent, controlled the pedestrian's direction by superimposing a visual illusion onto the raw images. When users walk, our system provides them with real-time feedback to their sight by processing the images that they have just perceived. To determine how to control pedestrian direction using the image processing method, we examined four image processing types: without processing, the moving stripe pattern method, magnification, and the changing focal region method. Based on the result, the changing focal region method worked most effectively for pedestrian movement control, and changed the pedestrian's walking path by about 190 mm/m on average.
