Abstract: An eyewear device is disclosed including an illumination device including illumination sources, each illumination source including a first illuminator, a second illuminator, and a third illuminator, and a spatial light modulator coupled to the illumination device to control when each of the first, second, and third illuminators are on during an illumination frame. The spatial light modulator is adapted to turn on the first illuminator while the second and third illuminators are off, turn on the second illuminator while the first and third illuminators are off, turn on the third illuminator while the first and second illuminators are off during a third time period of the illumination frame, and turn on the first, second and third illuminators during a fourth time period. An illumination method is also disclosed.

Abstract: Eyewear including a support structure defining a region for receiving a head of a user. The support structure supports optical elements, electronic components, and a use detector. The use detector is coupled to the electronic components and is positioned to identify when the head of the user is within the region defined by the support structure. The electronic components monitor the use detector and transition from a first mode of operation to a second mode of operation when the use detector senses the head of the user in the region.
