Abstract

The invention discloses a wide range friction control tactile reproduction device and method. The device comprises a tactile reproduction module, a piezoelectric ceramic excitation signal generation module, an electrode array excitation signal generation module, an electromagnet array excitation signal generation module, and a finger position detection module. module, a permanent magnet attached to the back of the operator's finger, and a central control module; the tactile reproduction module includes a tactile panel, a transparent electrode array module, a piezoelectric ceramic array module, an electromagnet array module, a display module and a housing. The reproduction method of the present invention combines the three principles of air pressure film effect, electro-vibration effect and electromagnetic force control to realize the increase and decrease of the friction force between the operator's finger and the tactile reproduction module. A tactile reproduction of performance. The invention can realize multimodal perception and has great practical value.

Description

technical field [0001] The invention relates to the field of human-computer interaction of tactile reproduction, in particular to a device and method for controlling tactile reproduction with wide-width friction force. Background technique [0002] Among the human perception systems such as vision, hearing, smell, taste and force touch, force touch provides a two-way information exchange channel between humans and the environment, forming various active behaviors that cannot be realized by other sensory systems (such as touch perception). objects, manipulating tools and exploring the environment, etc.), and thus have a unique importance. At present, tactile reproduction technologies mainly include: vibration-based tactile reproduction, force feedback device-based tactile reproduction, array-based tactile reproduction, etc. [0003] Vibration-based information representation is a commonly used mode of tactile reproduction. Various vibrotactile actuators provide a solution f...

Problems solved by technology

However, this method also has certain disadvantages: limited operating range, bulky, expensive, inherent and system stability of the equipment can easily affect the tactile reproduction performance, etc.

The advantage of the array tactile reproduction system is that it is more intuitive and can actively apply tactile stimulation to the operator, but it also has certain limitations: limited by the technology and technology level, high power consumption and cost, and difficult to miniaturize, etc.

The electrode array used in this tactile interface is not easy to process, and the adjustment range of the coefficient of friction is not wide enough
