Patent attributes
Wearable coherent light sensing systems and methods are disclosed. In one implementation, a system may include a wearable coherent light source configured to direct light towards a facial area; a wearable sensor configured to receive light source reflections and to output associated reflection signals; and a processor operable in an idle mode and in a high power mode. In the idle mode, the processor is configured to receive the reflection signals, process the reflection signals to identify trigger in the reflection signals, and automatically switch to the high power mode upon identification of the trigger. In the high power mode, the processor is configured to analyze the reflection signals to identify facial movements associated with silent speech. Following the identification of the facial movements associated with the silent speech, the processor is configured to decipher the facial movements and generate an output associated with the silent speech.
