Abstract
A stand-alone appliance can detect a user's face/eyes and provide violet light to the user. The appliance can include a fixture mounted on a platform and at least one motor to move the platform. A directed light source, coupled to a processor, can emit a light signal directed to an adjustable focal point. A camera, coupled to the processor, can detect the user and provide an image of the user's face to the processor. The processor can signal the motor to orient the platform to bring an eye into a center of a frame and adjust the focal point. A distance sensor, coupled to the processor, can estimate a distance between the fixture and the eye to ensure that an appropriate optical energy density is applied to the user. The camera, the directed light source, and/or the distance sensor can be embedded in the fixture.
