FINGERTIP TACTILE FEEDBACK APPARATUS BASED ON WEIGHTED AMPLITUDE-FREQUENCY VIBRATION SUPERPOSITION

WIPO Patent Application WO/2023/245786

A1

Disclosed in the present invention is a fingertip tactile feedback apparatus based on weighted amplitude-frequency vibration superposition, comprising fingerstalls, vibration conduction structures, straps, a touch screen, a control box, a wristband, and connecting wires. The fingerstalls are worn on fingertips, the vibration conduction structures are fixed to finger pulps of the fingerstalls and are connected to an interface of the control box by means of the connecting wires, the control box is fixed on the wristband and comprises a power supply, a Bluetooth module and a data processing module inside, and the touch screen is located above the control box. According to the present invention, the overall fluctuating state and the roughness degree of the surface of an object are simulated: two vibration motors are enabled to respectively generate high- and low-frequency vibrations, and by adjusting the weights of the amplitude and the frequency and superposing the two vibrations by means of the vibration conduction structures, different vibration waveforms are generated, and people feel different tactile sensations.
