Embodiment Construction

[0026] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0027] The learning and cognitive system based on texture tactile reproduction of the present invention has a structure such as figure 1 As shown, it includes an image acquisition device, a main control module, a drive module, a tactile reproduction module, and a finger position detection module.

[0028] In this specific embodiment, the tactile reproduction module, such as figure 2 As shown, it includes a transparent tactile panel 1 , a piezoelectric ceramic vibrating piece 2 , and a liquid crystal display 3 . Among them, there are 4 pieces of piezoelectric ceramic vibrating pieces 2, which are respectively installed at the four corners of the transparent tactile panel 1, so as to realize the consistency of the coefficient of friction on the entire tactile panel surface. The liquid crystal display screen 3 is arranged on the bottom of the tactile pa...

Abstract

The invention discloses a learning and cognitive system based on texture haptic display. The system comprises a haptic display module, a drive module, a finger position detection module, and a main control module, wherein the haptic display module includes a transparent haptic panel and a vibration device capable of making the haptic panel vibrate at different amplitudes; the drive module is respectively connected with the main control module and the vibration device, and is used for driving the vibration device to vibrate according to an instruction from the main control module; the finger position detection module is used for detecting the position information of a finger touching the haptic panel, and transmitting the position information to the main control module; and the main control module is used for extracting texture features of an externally-input image, calculating according to the extracted image features and the position information detected by the finger position detection module, and generating a corresponding control instruction to control the drive module so as to drive the vibration device to generate vibration. The system provided by the invention has plentiful and stable touch sense, and is suitable for the learning and cognition of character and image information for the blind and preschool children.

Description

technical field [0001] The invention relates to a learning and cognition system, in particular to a texture-tactile reproduction-based learning and cognition system, which is used for visually impaired people and preschool children to learn and cognition text and image information. Background technique [0002] As an emerging human-computer interaction technology, tactile reproduction has been paid more and more attention by people. Haptic reproduction technology enables operators to touch, perceive and manipulate virtual objects by means of tactile reproduction equipment and computer simulation environment. The existing tactile reproduction methods mainly include: tactile reproduction based on force sense reproduction, tactile reproduction based on array device, and tactile reproduction based on friction force control. [0003] The force sense reproduction device is mainly designed to realize the force feedback in the process of human-computer interaction. When the operat...
