Claim 9:
10. A system for determining textual transcription from minute facial skin movements, the system comprising:
at least one coherent light source;
at least one sensor configured to receive light reflections from the at least one coherent light source;
at least one processor configured to:
control the at least one coherent light source to illuminate a region of a face of a user;
receive from the at least one sensor, reflection signals indicative of coherent light reflected from the face in a time interval;
analyze the reflection signals to determine minute facial skin movements in the time interval, wherein analyzing the reflection signals to determine minute facial skin movements includes detection of changes in speckle patterns that occur due to the minute facial skin movements;
based on the determined minute facial skin movements in the time interval, determine a sequence of words associated with the minute facial skin movements; and
output a textual transcription corresponding with the determined sequence of words.
