Abstract
An eye-mounted device includes a contact lens, a femtocamera, and a femtoprojector. The femtocamera and femtoprojector are both contained in the contact lens. The femtocamera detects imagery of a user's surrounding environment, and the femtoprojector projects corresponding imagery to the user's retina. A line of sight of the femtocamera and a line of projection of the femtoprojector can be parallel to, or even collinear with, each other. Imagery signal paths from the femtocamera to the femtoprojector are also contained in the contact lens. In some embodiments, the imagery signal paths are register-less and asynchronous. The eye-mounted device can include other components, such as image processing circuitry. Also, the eye-mounted device can communicate with another device worn by the user, e.g., in a necklace or a headpiece.
