Lateral-Force-Based Haptic Display
Touching through a screen to a displayed object has been one of a goal of human interface.
Several researchers employ vibrations in order to display texture information. However no systems realize to display geometrical shapes and textures.
In this research we propose a method of feeling both large bump and precise textures simultaneously through a touchscreen. Our method employs lateral force and high frequency direction-controlled vibration. Vibration, normal to moving direction of finger enables independent display between geometrical and texture information. The technology realizes not only geometrical shapes but also textures to be felt.
