Tactile interaction device and method for 360-degree suspension light field three-dimensional display system

Abstract

The invention discloses a tactile interaction device and method for a 360-degree suspension light field three-dimensional display system, and belongs to the technical field of computer vision. The device comprises a Leap Motion arranged on one side of a high-speed rotating screen and used for collecting hand position information, a fingerstall with a vibration function and a processor used for processing information and transmitting signals. The processor is in communication connection with the Leap Motion to obtain hand position information, the processor is provided with a Bluetooth transmitting module, instructions are sent to the fingerstalls through the Bluetooth transmitting module to control vibration of the fingerstalls, and Bluetooth receiving modules are arranged in the fingerstalls. Finger information reading, coordinate conversion, model judgment, Bluetooth transmission, hardware driving and other steps are carried out to realize interaction of fingers and model force touch. When the fingers are in contact with the boundary of the display model within a certain range, the finger sleeves can exert vibration force on the fingers, and the effect of force tactile interaction is achieved. Namely, when the hand touches the display model, the fingers have vibration touch feeling. Therefore, more real sensory experience is provided for the user.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a tactile interaction device and method for a 360° suspended light field three-dimensional display system. Background technique [0002] With the development of computer science and projection technology, three-dimensional display technology has developed rapidly in recent years. Among them, the real 3D image can enable the observer to see the display in the space, and have a correct view and occlusion relationship when looking around the scene, and the 3D display with the naked eye has become a hot research topic. [0003] By reconstructing the light field of a 3D scene, a large-scale high-quality 3D color image display with correct occlusion relations can be realized. By simulating the way real objects emit light, the light field distribution of the 3D scene is reconstructed, so that different observers around the display system can see the correct 3D image. The scann...

Problems solved by technology

[0006] In the prior art, distributed tactile stimulation that is consistent with the three-dimensional shape information of the virtual object and the contact posture information between the fingers and the virtual object is fed back to the operator, thereby simulating the tactile sensation generated when the human hand touches a virtual object of different shapes with different postures. A technology that provides users with a good tactile interaction experience, such as a method for tactile reproduction of a virtual object's three-dimensional shape based on a finger-style device disclosed in the Chinese patent document with the publication number CN107831892A, but this technology uses a virtual three-dimensional scene, Unable to make users have a real sensory experience
