Head mountable systems, methods, and non-transitory computer readable media including instructions for identifying individuals using
facial skin micromovements are disclosed. An example head mountable
system may include a wearable housing, a coherent
light source, a
detector, and at least one processor. The at least one processor may analyze reflection signals from the
detector to determine specific
facial skin micromovements of an individual wearing the head mountable
system. Thereafter, the at least one processor may access memory correlating a plurality of
facial skin micromovements with the individual, and search for a match between the determined specific facial
skin micromovements and at least one of the plurality of facial
skin micromovements in the memory. If a match is identified, the processor may initiate a first action; and if a match is not identified, the at least one processor may initiate a second action different from the first action.
