AI Technical Summary

Problems solved by technology

At present, most of the haptic interaction devices of mobile terminals are designed by combining electrostatic force with mobile terminals, and there are few external haptic interaction devices.

Moreover, the existing external haptic devices generally have shortcomings such as bulky volume, high power consumption, and unrealistic and accurate haptic feedback, which cannot give users a good realistic experience of haptic interaction.

Inconvenient portability and poor applicability lead to poor practicality of most devices

[0004] Most of the published haptic interaction devices based on mobile terminals use different haptic generation methods, such as electrostatic membranes, vibration motors, electrode arrays, etc., but these devices often do not fully consider human haptic characteristics and interaction processes. Influence of the user's active finger force change and finger posture change on the force-tactile interaction experience

The mobile touch screen can only track the touch position of the finger but cannot obtain the gesture of the finger, so it cannot simulate the tactile sensation of the finger touching the virtual object to the greatest extent realistically, especially the tactile expression of hardness and shape

In some systems, the gesture of the user's finger is captured in real time through the camera, but this will greatly increase the size of the system, reduce portability and consume too much calculation

The finger interaction characteristics on the plane of these mobile terminals lack the detection of necessary depth and interaction posture information, which limits the accurate calculation and expression of the contact state in the virtual interaction process.
