Electronic device for supporting finger touch interaction and working method thereof

Abstract

Various embodiments of the present invention relate to an electronic device for supporting a finger touch interaction using a return loss of a radio frequency signal, and an operating method thereof, the present invention can release a radio frequency signal through an antenna and measure a return loss of the antenna, based on the measured return loss, it is confirmed whether or not a touch is made between a plurality of fingers separated by a preset distance from the antenna, whereby an interaction with the touch between the plurality of fingers can be provided.

Description

technical field [0001] Various embodiments of the present invention relate to electronic devices and methods of operation thereof for supporting finger touch interaction utilizing return loss of radio frequency signals. Background technique [0002] At present, the technology supporting finger touch interaction is mainly implemented by using a camera. The above technology utilizes the finger position information captured by the RGB camera or the depth camera to distinguish whether one finger is touched or not from another finger. However, the fingers that touch according to the position and direction of the hand cannot be distinguished by the camera because they are blocked by the back of the hand or other fingers. Methods of tracking the position of fingers without being limited by the position and angle of the camera include a method using the deformation of the back of the hand based on the movement of the fingers, a method using the deformation of the wrist and the arm,...

AI Technical Summary

Problems solved by technology

However, these methods indirectly estimate the position of the finger from the deformation of other parts of the finger, so it is difficult to distinguish whether the touch is based on the movement of the finger.

In addition, it is difficult to distinguish fine finger movements by using Doppler radar (Doppler radar) to measure hand movement to recognize gestures (gesture) or using a movement sensor.
