SYSTEMS, DEVICES, AND METHODS FOR WEARABLE HEADS-UP DISPLAYS
First Claim
1. A wearable heads-up display comprising:
- a support structure that in use is worn on a head of a user;
a transparent element that is physically coupled to the support structure, wherein the transparent element is positioned within a field of view of an eye of the user when the support structure is worn on the head of the user; and
a scanning projector positioned on or proximate a surface of the transparent element in the field of view of the eye of the user, the scanning projector comprising;
a light source; and
a dynamic optical beam-steerer positioned to receive light signals provided by the light source and controllably redirect the light signals towards select regions of the eye of the user.

Abstract
Systems, devices, and methods for transparent displays that are well-suited for use in wearable heads-up displays are described. Such transparent displays include one or more scanning projector(s) that is/are mounted on or proximate the lens portion(s) thereof, directly in the field of view of the user. Each scanning projector includes a respective light source that sequentially generates pixels or other discrete portions of an image and a respective dynamic optical beam-steerer that controllably steers the modulated light directly towards select regions of the eye of the user. Successive portions of the image are generated in rapid succession until the entire image is displayed to the user by projection directly onto the eye of the user from one or more point(s) within the user'"'"'s field of view.

15. A method of operating a wearable heads-up display when the wearable heads-up display is worn on a head of a user, the wearable heads-up display including a transparent element positioned in a field of view of an eye of the user and a scanning projector positioned in the field of view of the eye of the user on or proximate the transparent element, the scanning projector comprising a light source and a dynamic optical beam-steerer and the method comprising:
-
configuring the dynamic optical beam-steerer of the scanning projector in a first configuration within the field of view of the eye of the user; generating a first light signal representative of at least a first portion of an image by the light source of the scanning projector within the field of view of the eye of the user; and redirecting the first light signal towards a first region of the eye of the user by the dynamic optical beam-steerer of the scanning projector within the field of view of the eye of the user. - View Dependent Claims (16, 17, 18, 19, 20)
