A three-dimensional haptic rendering device and method based on plane interaction

Abstract

The invention relates to a three-dimensional haptic rendering device and a method based on plane interaction, belonging to the field of human-computer interaction. The device includes a positioning unit, a processing unit, a signal generator and an interaction unit, which can obtain the gray value and calculate the change rate of the corresponding gray value according to the position information of the finger on the image in real time, and further provide the tangential force by vibration, and provide the normal force by electrostatic force or air pressure film, and present the contour information by the three-dimensional haptic reproduction method based on the plane interaction. The advantages are: the portability of the device is good, at the same time, a tangential force and a normal force can be simultaneously applied to the finger, the feedback force is expanded from one dimension to two dimensions breaks through the restriction that electrostatic force only has feedback functionin the process of motion, the device and method realize the two-way width adjustment that the tangential force can be increased or decreased, and have more real three-dimensional haptic reproduction effect, which can be widely used in the field of human-computer interaction.

Description

technical field [0001] The invention belongs to the field of virtual reality and human-computer interaction, and in particular relates to a ternary fusion tactile reproduction device. Background technique [0002] The rapid development of science and technology has brought great changes to people's visual and auditory senses, causing overloading of people's visual and auditory senses, while touch, as a major sense of human beings, has not been fully utilized. In recent years, the field of artificial intelligence and human-computer interaction has ushered in an upsurge of development. As an important technology in the field of human-computer interaction, tactile reproduction technology occupies an important position in the realization of virtual reality and artificial intelligence. Efficient and natural tactile reproduction technology can give The perfect combination of people's real sense of immersion, hearing, vision and touch will give people a better multi-sensory experie...
