Tactile display and CAD system
First Claim
1. A tactile display that locally applies a stimulus on a finger joint position of a human palmar-side skin in response to a movement of a human hand, the display comprising:
- a tactile device wearable on the human hand and having at least one extensible rod that extends from a surface of the tactile device and that has a tip positioned to face toward a finger joint;
a sensor that detects a movement of the tactile device;
a memory unit that stores surface shape data of the object; and
a controller that controls a stroke from the surface of the tactile device to the tip of each rod;
wherein the controller is programmed to place in a virtual space a virtual object that is defined by the surface shape data, and to determine a position of the tactile device on a surface of the virtual object model based on an output of the sensor,wherein the controller is further programmed to determine the stroke of each rod in accordance with a height of a relief at a surface position of the virtual object corresponding to a position of each rod, andwherein the controller is further programmed to push the tip of each rod toward each corresponding finger joint in accordance with the determined stroke of each rod.

Abstract
Provided is a technique capable of allowing a person to perceive a fine relief on an object surface clearly. A tactile device of a tactile display slides above an object. The tactile device comprises three rods which are free to move up and down. Lower ends of the rods are in contact with a surface of the object. Upper ends of respective rods touch a palmar-side skin equivalent to positions of three joints of a first finger or a second finger. When the tactile device is slid, upper ends of respective rods move up and down in accordance with a surface relief of the object. In response to the movement of the tactile device, the three rods push three finger joint positions of the palmar-side skin with a stroke equal to a height of the relief.
