Problems solved by technology
Rutgers University invented the Rutgers Master II-ND, which can provide a maximum continuous force of 16N, and the air flow is controlled by a servo valve, but this drive device limits the range of finger movement
These pneumatic devices require more expensive servo valves or piezoelectric valves, and the use of compressed air to drive makes the entire device not safe enough and poor in portability

The invention discloses a pneumatically driven force feedback and tactile feedback apparatus. The force feedback and tactile feedback apparatus comprises a tactile-force feedback glove apparatus and a tactile-force control system, wherein the tactile-force control system comprises a main control module, a tactile feedback module, a force feedback module and an AD conversion module; the AD conversion module performs analog-digital conversion on finger force data acquired by a sensor arranged on the tactile-force feedback glove apparatus; the main control module controls the opening or closing of an air cylinder in the force feedback module according to the converted finger force data to generate force feedback, and controls a diaphragm pump in the tactile feedback module to fill an airbag with air according to the converted finger force data to generate tactile feedback; and the tactile-force feedback glove apparatus performs a movement according to the force feedback generated by a piston movement in the force feedback module and the tactile feedback generated by the airbag mounted on gloves in the tactile feedback module. The force feedback and tactile feedback apparatus has the advantages of safety, portability and low cost.
Description
technical field [0001] The invention relates to the technical field of tactile and force-sense human-computer interaction, in particular to a force feedback and tactile feedback device driven by air pressure. Background technique [0002] The emergence of virtual reality technology has changed the way humans interact with computers. VR headsets, such as the Oculus Rift, allow the user to experience the virtual environment that the user desires with their vision. In addition to sight and hearing, researchers are beginning to realize that information can be better understood by using more natural ways of interacting. In order to improve the immersion of interaction in the virtual world, haptic interaction devices allow humans to touch and manipulate virtual objects in a more intuitive way. It can be said that haptic interaction breaks the boundary between virtual and reality. [0003] Among the many devices that can provide haptic feedback to various parts of the human body,...
