Study on Tactile Perception of Shape for Effective Tactile Display
The experiment of the shape recognition for a tactile display is carried out and analysed in this paper. The purpose of this research is the development of a tactile stimulator array to represent the obstacle information for the visually impaired to walk safely. As a first step of this research, we investigate the characteristics of tactile stimuli and design the experimental system for the phy...
متن کاملA Tactile Shape Display Using RC Servomotors
Tactile displays are used to convey small-scale force and shape information to the tip of the finger. In this paper, we present a 6x6 tactile shape display that uses commercial RC servomotors to actuate an array of mechanical pins. The display has a maximum pin deflection of 2 mm along with a resolution of 4 bits. Pin spacing is 2 mm with a pin diameter of 1 mm. The display can accurately repre...
متن کاملIi Effect . of Display Movement on Tactile Pattern Perception
Bliss and Crane (1965) and Linvill and Bliss (1966)* found considerable improvement in subject performance when tactually displayed letters were presented sequentially along a moving ticker-tape (Times Square) display rather than just a single stationary letter at a time. To study these tactile spatialtemporal interaction effects further, it was decided to test a different mode of stimulus patt...
متن کاملThermo-tactile Interaction Using Tactile Display Device
This paper proposes a tactile display mouse providing both pin-array type tactile display and thermal display. Micro shape and vibrotactile stimuli can be generated by pin-arrayed tactile display and various planar distributed patterns can be also displayed such as Braille cell patterns. Temperature and thermophysical property of object can be displayed by the thermal display device that is com...
متن کاملEffective tactile noise facilitates visual perception.
The fulcrum principle establishes that a subthreshold excitatory signal (entering in one sense) that is synchronous with a facilitation signal (entering in a different sense) can be increased (up to a resonant-like level) and then decreased by the energy and frequency content of the facilitating signal. As a result, the sensation of the signal changes according to the excitatory signal strengt...
