摘要：
The disclosure features systems and methods for detecting a user's facial movement and expression, that include a plurality of radiation sources, a plurality of radiation detectors, where each radiation detector is paired with a different one of the radiation sources and configured to detect radiation emitted by its paired radiation source, and a controller connected to the radiation detectors and configured to receive signals corresponding to measurements of emitted radiation from each of the radiation detectors, determine, for each radiation source-detector pair, information about whether a radiation path between the source and detector is blocked by a portion of the user's face, and determine a facial movement or expression of the user based on the information.
