Embodiment Construction

[0017] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] figure 1 It is a functional block diagram of the present invention. Among them are the teacher's console 1, the tactile display controller 2, the touch point 3, the finger 4, the finger arm 5 and the angle sensor 6. Among them, the teacher console 1 sends the graphic information to the tactile display controller 2 through a wired or wireless connection, and the tactile display controller 2 analyzes the graphic information and establishes its relationship with figure 2 The graphic and text dot matrix data mapping relationship of the virtual tactile display area 12 in the center, and extract the graphic and text pixel parameters corresponding to the current position of the touch point 3, and drive the touch point 3 at the same time, and stimulate the operator's finger 4 to make it sense in a tactile way The image and te...

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. About 90% of the 10,000 blind people are in developing countries. The latest research shows that the number of blind people in countries around the world, especially in developing countries, continues to increase. To care for the blind, October 15th is the annual International Blind Day. There are currently 8.77 million visually disabled people i...
