Desktop feeling blind teaching device based on vision/feeling function replacement

Abstract

The invention provides a desk-top touch blind teaching device based on functional replacement of vision by touch. The desk-top touch blind teaching device comprises a teaching console, a touch display controller, a touch point, an upper arm angle sensor, an upper arm, a lower arm angle sensor, a lower arm, a finger-arm angle sensor, a touch display area and a desk, wherein, the teaching console is connected with the touch display controller which is connected with the touch point through the upper arm angle sensor, the upper arm, the lower arm angle sensor and the lower arm by wires; and the upper arm, the upper arm angle sensor, the lower arm and the touch point are placed on a desk in the manner of sequence cascade through the upper arm angle sensor. When a blind operator drives an arm link to move on the desk by the tip of a finger, the touch display controller can calculate in real time a touch graph-text pixel parameter at the position of the current touch point to cause the blind operator to perceive touch graph-text pixel information at the position of the current touch point in the manner of touch stimulation. The desk-top touch blind teaching device has simple structure and low cost and is convenient for use and characterized by real-time.

Description

technical field [0001] The invention relates to a table-top tactile blind teaching device used for teaching the blind, in particular to a table-top tactile blind teaching device that enables the blind to realize "visual-tactile function replacement" by means of virtual tactile display technology. Background technique [0002] People with disabilities have been born with disabilities. Blind people are a special group of people with visual impairment. According to the World Health Organization, there are currently nearly 45 million blind people in the world, 135 million people with visual impairment, and 4,500 blind people worldwide.
