Tactile pin display apparatus
First Claim
1. A dot figure display apparatus for displaying a dot figure on a pin matrix having a plurality of pins disposed in a matrix pattern on an upper surface of a dot figure display main body and allowing touch sense of said dot figure by touching said pin matrix with a finger tip, the dot figure display apparatus comprising:
- an infrared LED for irradiating infrared rays to a surface of said pin matrix;
a video camera for receiving said infrared rays reflected and detecting an infrared ray image reflected from a main finger tip depressed said pin matrix;
a pressure sensor for detecting a press force to said pin matrix; and
a control unit for detecting a touch position of said main finger tip on said pin matrix as a main finger tip touch position, in accordance with a detection result of the reflected infrared ray image of said video camera and detecting a press force to said pin matrix from a detection output of said pressure sensor.

Abstract
A pin matrix having a plurality of pins disposed in a matrix pattern is mounted on a display unit disposed on an upper surface of a dot figure display main body in the housing of a dot figure display apparatus. As pins are driven, a dot figure capable of being touched and sensed is displayed. Infrared rays are irradiated from an infrared LED to the pin matrix. A video camera receives infrared rays reflected from a recursive reflection marker attached to a main finger tip to detect the position of the main finger tip on the pin matrix. A pressure sensor is mounted at each corner of the dot figure display main body. A pressure barycenter position and a press force relative to the pin matrix are calculated from a pressure detected with each pressure sensor. The manipulation state of the pin matrix is judged from the main finger tip touch position, pressure barycenter position and press force.
