AI Technical Summary
Existing technologies make it difficult to integrate microphone functionality into contact lenses, especially since traditional microphones are incompatible with direct contact with the eyelids and are sensitive to airborne noise, making it impossible to effectively filter out environmental noise.
An accelerometer is used as a microphone to detect solid-borne sounds generated by the wearer. Taking advantage of the fact that the accelerometer is not sensitive to solid-borne sounds, it is integrated into the contact lens and connected to the communication circuit to achieve voice recognition and control.
It achieves clear voice signal acquisition in noisy environments, suppresses environmental noise, and combines voice detection and low-frequency acceleration sensing functions to meet the multifunctional needs of smart glasses.
