A haptic feedback method and terminal

Abstract

The invention discloses a tactile feedback method. The method comprises the steps of determining a corresponding regional electrode, in a first position of a terminal, of a touch point position of a user, and connecting the determined regional electrode with an electrode in a second position of the terminal to form an electrode loop; and inputting different low-frequency currents to the electrode loop through control, thereby feeding back different types of tactile senses to the user. Meanwhile, the invention furthermore discloses the terminal.

Description

technical field [0001] The invention relates to signal induction processing technology, in particular to a tactile feedback method and a terminal. Background technique [0002] When operating on mobile terminals such as mobile phones, tablets and other touch-screen electronic devices, the touch screen will not give feedback on pressure like physical buttons, nor will there be any other tactile feedback; for example, the lack of hand feeling when playing mobile games has always been insurmountable chasm. [0003] The industry is constantly trying to use many ways to enhance the interactive capabilities of touch devices. For example, Apple's latest application of 3D Touch technology enables the iPhone 6S to distinguish the weight of the user's pressure. The so-called 3D Touch technology is an improvement on the existing capacitive touch screen. The technology is upgraded by adding a deformation sensor under the existing touch screen to measure the deformation of the screen an...

Problems solved by technology

[0007] Among the above two feedback technologies, the physical tactile feedback technology has the following disadvantages: the size of the mechanical terminals that can generate motion is large, and it is not easy to integrate into electronic devices; it is easy to wear and tear, difficult to repair and replace, and consumes a lot of energy; the tactile sensation is single

[0008] For the current stimulation feedback technology, there are the following disadvantages: due to the small contact area between the finger and the screen, the generated coupling capacitance is very small, and the small-capacity capacitor has the characteristics of hindering the passage of low-frequency current and facilitating the passage of high-frequency current. The conductivity continues to increase, but as the frequency increases, the stimulating effect of the current on the body will rapidly weaken. Using the capacitive coupling method, the conductivity of the low-frequency current that can have exciting sensation and motor nerves below 1000Hz is very poor, so the resulting low-frequency Limited current size makes it difficult to provide obvious tactile feedback
