Projector alignment in a contact lens
First Claim
1. A contact lens comprising:
- a contact lens body;
a first femtoprojector embedded within the contact lens body and configured to project a first image onto a retina of a wearer of the contact lens;
a second femtoprojector embedded within the contact lens body and configured to project a second image onto the retina of the wearer of the contact lens; and
an alignment circuit configured to align the first femtoprojector and the second femtoprojector based on an input from the wearer of the contact lens.

Abstract
An electronic contact lens includes multiple femtoprojectors within the contact lens. Different femtoprojectors project images onto different portions of the retina. The images can be aligned by an alignment circuit within the contact lens. The alignment circuit can adjust the physical position or orientation of one or more femtoprojectors. Additionally, the alignment circuit can configure a location within a femtoprojector array from which an image is projected. A user can provide an input to align the femtoprojectors. For instance, a user can provide an input to adjust a location from which a first femtoprojector projects a test image until the test image is aligned with a test image projected by a second femtoprojector. The alignment circuit can, based on the user'"'"'s input, determine alignment information for the femtoprojectors, and the contact lens can project subsequent images based on the alignment information.

18. A method for calibrating an electronic contact lens comprising:
-
projecting, by a first femtoprojector embedded within the electronic contact lens, a first image onto a retina of a wearer of the electronic contact lens; projecting, by a second femtoprojector embedded within the electronic contact lens, a second image onto the retina of the wearer of the electronic contact lens; receiving, from the wearer of the electronic contact lens, an input based on the first image and the second image; and aligning, by the electronic contact lens, the first femtoprojector and the second femtoprojector based on the received input. - View Dependent Claims (19, 20)
