Abstract

A head mounted device includes a helmet with a guide, a lens frame, at least one display surface mounted to the lens frame. The guide extends from a cavity of the helmet. The lens frame is moveably connected to the guide and moves along an axis of the guide between a first position within the cavity of the helmet and a second position outside the cavity of the helmet. The display surface is transparent and configured to display augmented reality content.

First claim

What is claimed is:

1. A head mounted device comprising:
an enclosure having a cavity;
a visor coupled to the enclosure;
a guide extending from the enclosure;
a lens frame coupled to the guide, the lens frame configured to move along an axis of the guide between a first position within the cavity of the enclosure and a second position outside the cavity of the enclosure;
a first and a second display lens mounted to the frame, the first and second display lens being distinct from the visor;
an optical sensor configured to detect real-world objects in a physical environment;
a receiver module configured to determine that a real-world object detected by the optical sensor is associated with an Augmented Reality (AR) content and, in response to determining that the real-world object detected by the optical sensor is associated with the AR content, cause the lens frame to extend from the first position to the second position; and
an augmented reality module, implemented by a hardware processor, configured to cause display of the AR content on at least the first display lens in response to the lens frame being extended from the first position to the second position.

2. The head mounted device of claim 1 , wherein the enclosure comprises a helmet, wherein the guide extends away from a cavity of the helmet, wherein the at least one display lens is transparent and configured to display augmented reality content.

3. The head mounted device of claim 1 , further comprising:
a motor disposed within the enclosure; and
a belt connecting the motor to the lens frame, wherein the motor is configured to wind a portion of the belt to move the lens frame to the first position of the lens frame, and to unwind the portion of the belt to move the lens frame to the second position of the lens frame.

4. The head mounted device of claim 3 , further comprising:
a belt guide disposed adjacent to the motor in the cavity of the enclosure, wherein the belt guide routes the belt from the motor to the lens frame, a portion of the belt between the belt guide and the lens frame being parallel to the axis of the guide.

5. The head mounted device of claim 1 , further comprising:
an actuator disposed within the enclosure, wherein the actuator is configured to extend and contract along the axis of the guide between the first position of the lens frame and the second position of the lens frame.

6. The head mounted device of claim 1 , further comprising:
a sensor configured to detect a first condition and a second condition,
the controller further configured to initiate an extension of the lens frame from the first position to the second position in response to the sensor detecting the first condition, and to initiate a retraction of the lens frame from the second position to the first position in response to the sensor detecting the second condition.

7. The head mounted device of claim 6 ,
wherein the augmented reality module is further configured to cause at least the first display lens to display augmented reality content in response to the first condition, and to cause at least the first display lens to hide the augmented reality content in response to the second condition.

8. The head mounted device of claim 6 ,
wherein the augmented reality module is configured to cause at least the first display lens to display augmented reality content in response to the lens frame being in the second position, and to cause at least the first display lens to hide the augmented reality content in response to the lens frame being in the first position.

9. The head mounted device of claim 6 , wherein the sensor comprises an audio sensor or an optical sensor.

10. The head mounted device of claim 6 , further comprising:
a wireless module configured to wirelessly communicate with a wearable device external to the head mounted device, the wireless module configured to receive a first message and a second message from the wearable device, wherein the controller is configured to correlate the first message with the first condition and the second message with the second condition.

11. The head mounted device of claim 10 , wherein the first message corresponds to a first state of the wearable device, the second message corresponds to a second state of the wearable device.

12. The head mounted device of claim 11 , wherein the first state of the wearable device corresponds to a first relative position between the wearable device and the head mounted device, wherein the second state of the wearable device corresponds to a second relative position between the wearable device and the head mounted device.

13. The head mounted device of claim 6 , wherein the controller is configured to power on at least the first display lens in response to the first condition, and to power off at least the first display lens in response to the second condition.

14. The head mounted device of claim 6 , wherein the controller is configured to power on at least the first display lens in response to the lens frame being in the first position, and to power off at least the first display lens in response to the lens frame being in the second position.
