Problems solved by technology

[0007] The vibration feedback method needs a motor, which is bulky and consumes a lot of power. At the same time, the electronic device will also emit sound when it vibrates, which has poor confidentiality; the sound feedback method causes noise interference to the environment and has poor confidentiality. At the same time, it is difficult for users to hear electronic devices in noisy environments. sound of feedback

Abstract

The invention discloses a man-machine interaction feedback device and a method thereof. The device includes a detection module and an electrical contact module, wherein the detection module is used to detect whether an incident is triggered or not, and when the incident is triggered, the detection module informs the electrical contact module; the electrical contact module is used to give an electrical stimulation to a human body of a people who triggered the incident when that the incident is triggered is detected by the detection module. In the invention, by giving the electrical stimulation to the human body of the people who triggered the incident when that the incident is triggered is detected, the user is enable to perceive feedback even in a noisy condition without any noise interference, thereby improving the confidentiality as well as reducing the device volume and the power consumption.

Description

technical field [0001] The invention relates to the field of electronic circuits, in particular to a human-computer interaction feedback device and method. Background technique [0002] When a user performs human-computer interaction with an electronic device through a trigger point or other means, the electronic device usually designs a trigger point feedback behavior to notify the user that the operation of the trigger point has been received. [0003] Currently, human-computer interaction feedback methods mainly include vibration feedback methods and sound feedback methods. [0004] The vibration feedback method is that when the main chip detects that an event is triggered, it sends a control signal to the motor, which can drive the motor to vibrate, thereby achieving the effect of vibration feedback. [0005] The sound feedback method is to send a control signal to the speaker when the main chip detects that the event is triggered. The control signal can be an electrica...
