Abstract

The invention relates to a method for interacting with an object that is displayed to a user by smart glasses, which includes a display. The method includes displaying the object for the user using the display, detecting that the user closes a first eye and keeps the first eye closed during a predetermined period of time using a first camera, recording a hand of the user using a second camera determining that the user performs an input action during the predetermined period of time, wherein the input action includes the hand assuming an attitude, and a position from a perspective of a second eye of the user with respect to the object, that meet a predetermined condition, and performing an action with respect to the object, wherein the action is associated with the input action in advance.

Claims

1. A method for interacting with an object being displayed to a user via smart glasses, the smart glasses comprising a display, the method comprising acts of:

displaying the object for the user using the display of the smart glasses;

detecting that the user closes a first eye and keeps the first eye closed during a predetermined period of time using a first camera configured to record the first eye of the user;

recording a first hand of the user using a second camera;

determining that the user performs a first input action for the object during the predetermined period of time, wherein the first input action includes the first hand of the user assuming an attitude, and a position from a perspective of a second eye of the user with respect to the object, that meet a predetermined condition; and

carrying out a first action with respect to the object, wherein the first action is associated with the first input action in advance.

2. The method according to claim 1, wherein the predetermined condition includes one or more of the following:

an attitude of the first hand in which a ring or a circle is formed with one or more fingers, and the first hand is positioned such that the object is enclosed by the ring or circle from the perspective of the second eye;

an attitude of the first hand in which a thumb and an index finger are extended to form or symbolize an angle of approximately 90 degrees, and the first hand is positioned such that the object is at least partially located in an imaginary rectangle from the perspective of the second eye, wherein the imaginary rectangle has two short edge lengths corresponding to a length of the thumb and two long edge lengths corresponding to a length of the index finger, and a position of the imaginary rectangle from the perspective of the second eye is such that two edges correspond to the thumb and index finger;

an attitude of the first hand in which the thumb and the index finger, together, form approximately a U shape, and the first hand is positioned such that the object is at least partially contained in the U shape from the perspective of the second eye; and

an attitude of the first hand in which only the index finger is extended and the hand is positioned such that the index finger touches the object, or at least points in a direction of the object, from the perspective of the second eye.

3. The method according to claim 1, further comprising the act of:

recording a second hand of the user using the second camera;

wherein the first input action further includes the second hand of the user assuming an attitude and, a position from the perspective of the second eye of the user with respect to the object, that meet the predetermined condition, wherein the predetermined condition further includes the attitude and the position for both the first hand and the second hand.

4. The method according to claim 3, wherein the predetermined condition further includes:

an attitude of the first hand and an attitude of the second hand in which, for each attitude, a respective thumb and a respective index finger, together, form approximately a U shape, and the first hand and the second hand are each positioned such that the object is at least partially contained in the respective U shape from the perspective of the second eye, wherein the attitude and the position of the first hand and the second hand are such that openings of the respective U shapes point towards one another.

5. The method according to claim 1, the act of determining that the user performs the first input action further comprising:

determining a spatial position of the first hand with respect to a position of the display of the smart glasses; and

determining a position of the object within the display,

wherein a spatial position of the second eye with respect to the display of the smart glasses is known.

6. The method according to claim 1, the act of determining that the user performs the first input action further comprising:

determining a spatial position of the first hand with respect to the second eye of the user;

determining a position of the object within the display;

determining optical paths or vectors from points of the first hand to the second eye of the user;

determining a position of an intersection of the optical paths or the vectors using the display of the smart glasses; and

determining a position of the intersection with respect to the displayed object using the display;

wherein a spatial position of the second eye with respect to the display of the smart glasses is known.

7. The method according to claim 5, wherein the smart glasses includes the second camera and a direction of recording of the second camera is in a direction of viewing of the user looking straight ahead and the second camera is configured to determine one or more distances of at least some recorded picture elements in the recording.

8. The method according to claim 1, wherein the smart glasses includes the first camera.

9. The method according to claim 1, further comprising the acts of:

determining that the user performs a second input action during the predetermined period of time wherein the second input action includes the first hand of the user abandoning the attitude associated with the first input action, or the first hand of the user assuming a predetermined attitude; and

carrying out a second action with respect to the object, wherein the second action is associated with the second input action in advance.

10. The method according to claim 1, further comprising the act of:

displaying parts of the object only in areas in which the hand of the user, from the perspective of the second eye of the user, is not covered.

13. The method according to claim 2, wherein the ring or the circle is formed with the thumb and the index finger of the user.

14. The method according to claim 6, wherein the smart glasses includes the second camera and a direction of recording of the second camera is in a direction of viewing of the user looking straight ahead and the second camera is configured to determine one or more distances of at least some recorded picture elements in the recording.

11. A device comprising:

a display;

a first camera;

a second camera; and

at least one processor executing stored program instructions to;

display an object for a user using the display;

detect that the user closes a first eye and keeps the first eye closed during a predetermined period of time using the first camera configured to record the first eye of the user;

record a hand of the user using the second camera;

determine that the user performs an input action for the object during the predetermined period of time, wherein the input action includes the hand of the user assuming an attitude, and a position from a perspective of a second eye of the user with respect to the object, that meet a predetermined condition; and

carry out an action with respect to the object, wherein the action is associated with the input action in advance.

15. The device according to claim 11, wherein the device is smart glasses.

12. A non-transitory computer readable medium storing program instructions, the program instructions when executed by at least one processor performs a method comprising acts of:

displaying an object for a user using a display;

detecting that the user closes a first eye and keeps the first eye closed during a predetermined period of time using a first camera configured to record the first eye of the user;

record a hand of the user using a second camera;

determining that the user performs an input action for the object during the predetermined period of time, wherein the input action includes the hand of the user assuming an attitude, and a position from a perspective of a second eye of the user with respect to the object, that meet a predetermined condition; and

carrying out an action with respect to the object, wherein the action is associated with the input action in advance.

16. The non-transitory computer readable medium according to claim 12, wherein the computer program is executed on smart glasses.
