An Expansion of Space Affordance by Sound Beams and Tactile Indicators
The information in mobile terminal should be connected to objects in an immediate space where a pedestrian walks. We propose a mobility assistance system by parametric speakers cooperating with the Braille blocks with embedded IC-tag so as to allow pedestrians to safely perform tasks in the artificial “space affordance.” Complicated structures in a town, perceptive information and cognitive information useful for various scenes in the town are also discussed.
