Abstract

Disclosed are a system and a method for hands free operating of a head mounted device. An example method includes reading sensor data from sensors associated with a head mounted device worn by a user. The method allows recognizing, based on the sensor data, a gesture generated by a movement of a head of the user. In response to the recognition, an operation associated with the recognized gesture and a mode of the head mounted device of the head mounted device is performed. The gesture can include a rotation, a pitch, and a roll. The operation includes zooming an image on a screen of the head mounted device, panning the image, scrolling a series of images on the screen, and switching modes of the device. A speed of execution of the operation is proportional to a ratio determined from an angle of the head movement.

Claims

1. A method for hands free operating of a head mounted device, the method comprising:

reading sensor data from at least one sensor associated with a head mounted device, the head mounted device being worn by a user;

recognizing, based on the sensor data, a gesture generated by a movement of a head of the user; and

in response to recognition, performing an operation of the head mounted device, the operation being associated with the recognized gesture and a mode of the head mounted device.

2. The method of claim 1, wherein the gesture includes one or more of the following:

a rotation, a pitch, and a roll.

3. The method of claim 1, wherein the operation includes one of:

zooming in and zooming out an image displayed by a screen of the head mounted device, panning the image on the screen, scrolling a series of images on the screen, and switching the mode.

4. The method of claim 3, wherein the switching the mode is carried out in response to a left head tilt to at least a pre-determined angle.

5. The method of claim 3, wherein:

the zooming out the image is carried out in response to rotating the head from a center to the right; and

the zooming in the image is carried out in response to rotating the head from the center to the left.

6. The method of claim 3, wherein a direction of scrolling the series of the images is determined in response to rotating the head from a center to the left or to the right.

7. The method of claim 1, wherein recognizing of gestures includes determining a ratio based at least on an angle associated with the movement and a pre-determined maximum angle in a direction of the movement.

8. The method of claim 7, wherein a speed of execution of the operation is proportional to the ratio.

9. The method of claim 8, further comprising providing at least one indicator on a screen associated with the head mounted device, the at least one indicator showing a degree of fulfillment of the operation.

10. The method of claim 1, wherein recognizing the gesture includes

determining that parameters of the movement exceed minimal pre-defined thresholds.

11. A system for hands free operating of a head mounted device, the system comprising:

a processor;

a memory communicatively coupled to the processor, the memory storing instructions which when executed by the processor perform operations comprising;

reading sensor data from at least one sensor associated with a head mounted device, the head mounted device being worn by a user;

recognizing, based on the sensor data, a gesture generated by a movement of a head of the user; and

in response to the recognition, performing an operation of the head mounted device, the operation being associated with the recognized gesture and a mode of the head mounted device.

12. The system of claim 11, wherein the gesture includes one or more of the following:

a rotation, a pitch, and a roll.

13. The system of claim 11, wherein the operation includes one of the following:

zooming in and zooming out an image displayed by a screen of the head mounted device, panning the image on the screen, scrolling a series of images on the screen, and switching the mode.

14. The system of claim 13, wherein the switching of the mode is carried out in response to a left head tilt to at least a pre-determined angle.

15. The system of claim 13, wherein:

the zooming out of the image is carried out in response to rotating the head from a center to the right; and

the zooming in the image is carried out in response to rotating the head from the center to the left.

16. The system of claim 13, wherein a direction of scrolling the series of the images is determined in response to rotating the head from the center to the left or to the right.

17. The system of claim 11, wherein recognizing the gestures includes determining a ratio based at least on an angle associated with the movement and a pre-determined maximum angle in a direction of the movement.

18. The system of claim 17, wherein a speed of execution of the operation is proportional to the ratio.

19. The method of claim 18, further comprising providing at least one indicator on a screen associated with the head mounted device, the at least one indicator showing a degree of fulfillment of the operation.

20. A non-transitory computer-readable medium having instructions stored thereon, which when executed by one or more processors, perform the following operations:

reading sensor data from at least one sensor associated with a head mounted device, the head mounted device being worn by a user;

recognizing, based on the sensor data, a gesture generated by a movement of a head of the user; and

in response to recognition, performing an operation of the head mounted device, the operation being associated with the recognized gesture and a mode of the head mounted device.
