METHOD AND APPARATUS FOR DETERMINING AN INDICATION OF A POINTED POSITION ON A DISPLAY DEVICE
According to an embodiment, a direction pointed by a controlling device with a first orientation may be obtained from a first image of a user handing the controlling device with the first orientation. For example, an initial indication of an initial pointed position may be displayed on a display device based on the direction. For example, angular information may be obtained. The angular information may be representative of a difference between the first orientation and a second orientation of the controlling device pointing to the pointed position. For example, an indication of a pointed position may be determined (e.g., for display) based on the initial pointed position and on the received angular information.
1 . A method comprising:
obtaining a direction pointed by a controlling device with a first orientation, the direction being obtained from a first image of a user handing the controlling device with the first orientation;
determining a first indication of a first pointed position on a display based on the direction;
obtaining angular information representative of a difference between the first orientation and a second orientation of the controlling device pointing to a second pointed position on the display; and
determining a second indication of the second pointed position on the display based on the first pointed position and on the obtained angular information.
2 . The method of claim 1 , wherein obtaining the angular information comprises receiving the angular information from the controlling device.
3 . (canceled)
4 . The method of claim 1 , comprising obtaining the first pointed position based on a projection of a first position of the controlling device along the obtained direction on the display.
5 . The method of claim 1 , wherein the second indication of the second pointed position is determined independently from a subsequent projection along a subsequent direction pointed by the controlling device.
6 . The method of claim 1 , comprising determining that the controlling device is pointing to the display before determining any of the first indication and the second indication.
7 . The method of claim 1 , wherein determining the first indication of the first pointed position comprises superimposing the first indication of the first pointed position on content at a center position on the display.
8 . The method of claim 1 , wherein determining the first indication of the first pointed position comprises modifying a visual property of an element to be displayed at a center position of the display.
9 . The method of claim 1 , wherein determining any of the first indication and the second indication comprises superimposing any of the first indication and the second indication at respectively any of the first pointed position and the second pointed position on the display.
10 . The method of claim 1 , wherein determining any of the first indication and the second indication comprises modifying a visual property of an element to be displayed at respectively any of the first pointed position and the second pointed position.
11 . The method of claim 8 , wherein modifying the visual property of the element comprises any of highlighting, resizing and surrounding the element.
12 - 16 . (canceled)
17 . An apparatus comprising a processor configured to:

determine a first indication of a first pointed position on a display based on the direction;
obtain angular information representative of a difference between the first orientation and a second orientation of the controlling device pointing to a second pointed position on the display; and
determine a second indication of the second pointed position on the display based on the first pointed position and on the obtained angular information.
18 . The apparatus of claim 17 , comprising the display configured to display the determined second indication of the second pointed position.
19 . The apparatus of claim 17 , wherein the processor is configured to receive the angular information from the controlling device.
20 . (canceled)

22 . The apparatus of claim 17 , wherein the processor is configured to determine the second indication of the second pointed position independently from a subsequent projection along a subsequent direction pointed by the controlling device.
23 . The apparatus of claim 17 , wherein the processor is configured to determine that the controlling device is pointing to the display before determining any of the first indication and the second indication.
24 . The apparatus of claim 17 , wherein the processor being configured to determine the first indication of the first pointed position comprises the processor being configured to superimpose the first indication of the first pointed position on content at a center position on the display.
25 . The apparatus of claim 17 , wherein the processor being configured to determine the first indication of the first pointed position comprises the processor being configured to modify a visual property of an element to be displayed at a center position of the display.
26 . The apparatus of claim 17 , wherein the processor being configured to determine any of the first indication and the second indication comprises the processor being configured to superimpose any of the first indication and the second indication at respectively any of the first pointed position and the second pointed position on the display.
27 . The apparatus of claim 17 , wherein the processor being configured to determine any of the first indication and the second indication comprises the processor being configured to modify a visual property of an element to be displayed at respectively any of the first pointed position and the second pointed position.
