3 results about "Tactile display" patented technology

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.

Systems, methods, and apparatuses for rendering fine detail surface geometry on an active surface haptic display. One system includes a haptic surface, a plurality of actuators and a plurality of channel decorrelator elements. Each actuator is configured to generate mechanical waves in the haptic surface through control of each of the plurality of actuators, and wherein individual pixels of a plurality of pixels of the haptic surface are individually addressable by multiplexing of (either time or frequency of) the mechanical waves which generate mechanical displacement of one or more vector axes at locations of each of the individual pixels, wherein the plurality of channel decorrelator elements are located and configured to decorrelate different transmission paths between the plurality of actuators and the locations of the plurality of pixels on the haptic surface.
