Abstract

A method of pointing a first object on a screen of an infotainment system is provided. The first object on the screen is displayed on the screen and, a location of a second object related to a user and a first predetermined gesture executed by the second object by one or more sensors can be detected. Coordinates of a center of the first object on the screen can be calculated based on the detected location of the second object where the coordinates cause a distance between the center of the first object and the second object substantially minimum, and a size of the first object associated with a distance between the detected location of second object and the screen is calculated. The first object with the calculated size at the calculated coordinates is displayed on the screen.

Claims

1. A method of pointing a first object on a screen of an infotainment system, the method comprising:

displaying the first object on the screen;

detecting a location of a second object related to a user and a first predetermined gesture executed by the second object by one or more sensors;

calculating coordinates of a center of the first object on the screen based on the detected location of the second object, wherein the coordinates are configured to cause a distance between the center of the first object and the second object substantially minimum;

calculating a size of the first object associated with a distance between the detected location of second object and the screen; and

displaying the first object with the calculated size at the calculated coordinates on the screen.

2. The method of pointing an object in the screen of claim 1, wherein the first object is a pointer.

3. The method of pointing the object in the screen of claim 1, wherein the first object is an object of interest comprising one or more target objects.

4. The method of pointing the object in the screen of claim 1, wherein the first object is a region of interest and the size of the first object is associated with a display scale of the region of interest.

5. The method of pointing the object in the screen of claim 1, wherein the first object is a combination of a pointer and a region of interest and the size of the first object is associated with a combination of a size of the pointer and a display scale of the region of interest.

6. The method of pointing the object in the screen of claim 1, wherein at least one of the one or more sensors is a gesture sensor.

7. The method of pointing the object in the screen of claim 6, wherein the gesture sensor is at least one of a camera, a proximity sensor, such as a projected capacitive touch sensor without direct touch, photoelectric sensor, thermo-sensor, radar, ultrasonic sensor, a gyro and an accelerometer, attached to or remotely located from the screen.

8. The method of pointing the object in the screen of claim 1, further comprising:

detecting a second predetermined gesture as a confirmation of a function to be executed.

9. The method of pointing the object in a screen of claim 8, wherein the function to be executed is a selection of a portion of the first object, further comprising:

selecting the portion of the first object.

10. The method of pointing the object in the screen of claim 9, wherein a selection of one object is achieved by repetition of selecting the portion of the first object according to gesture change of the user.

11. An infotainment system that allows a user to point a first object on a screen, the system comprising:

a screen configured to display the first object on the screen; and

one or more gesture sensor configured to detect a location of a second object related to a user and a first predetermined gesture executed by the second object;

a processor configured to calculate coordinates of a center of the first object on the screen based on the detected location of the second object, wherein the coordinates are configured to cause a distance between the center of the first object and the second object substantially minimum,

wherein the processor is further configured to calculate a size of the first object associated with a distance between the detected location of second object and the screen and to display the first object with the calculated size at the calculated coordinates on the screen.

12. The infotainment system of claim 11, wherein the first object is a pointer.

13. The infotainment system of claim 11, wherein the first object is an object of interest comprising one or more target objects.

14. The infotainment system of claim 11, wherein the first object is a region of interest and the size of the first object is associated with a display scale of the region of interest.

15. The infotainment system of claim 11, wherein the first object is a combination of a pointer and a region of interest and the size of the first object is associated with a combination of a size of the pointer and a display scale of the region of interest.

16. The infotainment system of claim 11, wherein at least one of the one or more sensors is a gesture sensor.

17. The infotainment system of claim 16, wherein the gesture sensor is at least one of a camera, a proximity sensor, such as a projected capacitive touch sensor without direct touch, photoelectric sensor, thermo-sensor, radar, ultrasonic sensor, a gyro and an accelerometer, attached to or remotely located from the screen.

18. The infotainment system of claim 11, wherein the gesture sensor is further configured to detect a second predetermined gesture as a confirmation of a function to be executed.

19. The infotainment system of claim 18, wherein the function to be executed is a selection of a portion of the first object, further comprising:

selecting the portion of the first object.

20. The infotainment system of claim 19, wherein a selection of one object is achieved by repetition of allowing a user to select the portion of the first object according to gesture change of the user.
