Abstract
A wearable head-up display which allows for convenient and safe stowage when not in use. A hinge component is positioned within the optical path from an image projector to a display component which ensures optical alignment for projection. A detection means is provided to signal when the wearable device is in a folded position in order to deactivate the projector.
Claims20
A wearable head-up display, comprising:
- an arm supporting an image projector including at least one collimation optic for directing image-bearing light;
- and
- a frame supporting a combiner assembly, wherein the frame is hingeably attached to the arm by a hinge at a location between the collimation optic and the combiner assembly, such that the combiner assembly is arranged to receive the image-bearing light output by the image projector when the hinge is in an unfolded position.
A wearable head-up display system, comprising:
- an image projector configured to output image-bearing light;
- an arm supporting the image projector;
- a frame to which the arm is hingeably attached by a hinge, such that the arm has a range of movement relative to the frame, the range of movement including an unfolded position and a folded position;
- and
- a combiner supported by the frame and arranged to receive the image-bearing light output by the image projector and to direct the received light to a wearer's eye,
- wherein the image projector is arranged to output the image-bearing light onto a surface when the hinge is in a folded position.

A wearable head-up display system, comprising:
- a processing device configured to receive data;
- an image projector including at least one collimation optic and configured to output image-bearing light representative of the data;
- a first arm and a second arm, one of the first and second arms supporting the image projector;
- a frame to which each of the first and second arms is hingeably attached by a corresponding hinge, such that each of the first and second arms has a range of movement relative to the frame, the range of movement including an unfolded position and a folded position;
- and
- a combiner supported by the frame and arranged to receive the image-bearing light output by the image projector and to direct the received light to a wearer's eye,
- wherein one of the corresponding hinges is located between the collimation optic and the combiner.
