The invention discloses a music teaching touch device for blind people, which comprises a supporting seat and a teaching touch seat, and a plurality of dynamic dot matrix seats are arranged on the teaching touch seat in an array. Three rows and two columns of flexible pads are arranged at the top of each dynamic dot matrix base to form a Braille display matrix, and an electromagnetic plunger assembly is arranged below each dynamic dot matrix base to independently drive each dot position to protrude and reset, so that dynamic display of music Braille and graphs is achieved. The bottom of the dynamic dot matrix seat is connected through a silica gel bowl, and a conducting strip is arranged in the bowl and can be in contact with a corresponding conducting material on a circuit board in the teaching touch seat. When a user presses the dynamic dot matrix seat displaying specific notes, pitch sounding of the notes is triggered. According to the invention, the dynamic tactile display function and the pressing input function are integrated, so that refreshing and interactive learning of the braille music score are realized, and a multi-mode feedback closed loop is realized through tactile sense, auditory sense and operation.

A tactile human-user interface system provides a refreshable tactile display that communicates text and images. The system includes a processor and a set of transducers. The processor receives text and / or image input and defeatures any images in the input to produce a simplified image. The processor translates the input into tactile form, which it converts into a set of electrical signals associated with a set of pixels of a display. Each transducer of the set of transducers corresponds to a respective pixel of the set of pixels. The set of transducers receive, from the processor, the set of electrical signals. The set of transducers generates, in response to the set of electrical signals, tactile outputs, detectable by a finger of a human user, at locations corresponding to the set of pixels.

This application provides a large-format portable Braille reader, belonging to the technical field of tactile display for the blind. Specifically, it includes a control motherboard, an infrared detection device, a controller, and a tactile display device. The controller has a communication interface for communicating with an external host computer. The host computer sends control signals to the controller to control the touch points of the tactile display device to protrude or retract. The controller receives gesture marking information and analyzes it in conjunction with the state of each touch point of the tactile display device when the person marks the gesture to obtain touch point marking information. The touch point marking information includes the state of the touch points in the marked area when the person marks the gesture. The controller sends the touch point marking information to the host computer for storage. The host computer converts the touch point marking information into control signals to control the protrusion or retraction of the touch points in the corresponding area of ​​the tactile display device. This allows for the reproduction of the Braille in the marked area, enabling note archiving and rereading.

This application provides an electronic paper display panel and an electronic paper display device. The electronic paper display panel includes: a substrate and an array substrate stacked together, multiple pixel electrodes, and multiple receiving cavities corresponding to the multiple pixel electrodes; the receiving cavities are filled with reactants, multiple first charged particles, and multiple second charged particles; wherein the surface of the first charged particles is coated with a first photocatalyst, and the surface of the second charged particles is coated with a second photocatalyst; an elastic film is disposed on the side of the receiving cavity opposite to the substrate. The first photocatalyst can cause the reactants to decompose under light and generate gas, causing the elastic film to bulge; the second photocatalyst can cause the gas to undergo a chemical reaction under light and generate reactants, causing the elastic film to recover its deformation. This electronic paper display panel can achieve tactile display by controlling the deformation of the elastic film under ambient light.

This invention relates to the field of human-computer interaction technology, providing a haptic display device that integrates tactile and motion-sensing displays. The tactile display unit in this device is adapted to conform to a localized area of ​​the user's skin and generates pressure feedback on the skin based on input signals. The motion-sensing display unit is adapted to be fixed to both sides of a joint on the user's body and generates torque feedback at the joint. A flexible connector passes through the motion-sensing display unit and connects to the tactile display unit. When the user's joints move, the tension of the flexible connector changes, and this tension change is transmitted to the tactile display unit to generate localized pressure, simultaneously generating corresponding torque feedback at the joint. This invention mechanically couples tactile and motion sensations together through a single flexible connector, ensuring a high degree of synchronization between the two sensations in time and intensity, thus enhancing the realism and immersion of the tactile feedback.
