Abstract

A method and apparatus for determining an indication of interaction in a direction towards a webcam. The method includes the steps of determining an object in a region of interest, determining a first size of the object in the region of interest and tracking the object in the region of interest. A second size of the object in the region of interest is then determined, and a push interaction is confirmed as having taken place if the ratio of the second size to the first size is greater than a predetermined value.

Claims

1. A method for determining proper positioning of an object relative to a camera, comprising:

presenting on a display of a device an indication of a desired location for placement of the object relative to a field of view of the camera;

determining a movement of the object towards the camera when it appears that the object is moving angularly away from the camera but its size is not changing materially;

determining a position of the object within the field of view of the camera relative to the desired location for placement of the object based on at least the determined movement of the object towards the camera;

providing one or more instructions in response to the determination of the position of the object to the desired location to aid in guiding the user to move the object within the field of view of the camera towards the desired location;

determining a further position of the object within the field of view of the camera relative to the desired location for placement of the object; and

presenting on the display an indication of proper positioning of the object within the field of view of the camera relative to the desired position of the location for placement of the object.

2. The method of claim 1, wherein guiding placement of the object relative to the indication of desired location for placement of the object is repeated until it is confirmed that the object is properly placed.

3. The method of claim 1, further comprising employing the determined movement of the object towards the camera to aid in determining positioning of the object relative to the desired location for placement of the object.

4. The method of claim 1, further comprising displaying an image of the desired location for the placement of the object.

5. The method of claim 4, wherein the desired location for the placement of the object is displayed to a user to aid in properly placing the object.

6. The method of claim 1, wherein if the object is removed from a field of view of the camera and then repositioned within the field of view of the camera, determining a position of the object is performed again.

7. The method of claim 1, wherein the object is a medication pill.

8. The method of claim 1, wherein the object is a free standing object.

9. A system for determining proper positioning of an object relative to a camera, comprising:

a webcam for capturing one or more images;

a display arranged to present an indication of a desired location for placement of the object-relative to a field of view of the camera; and

a processor arranged to process the one or more captured images, the processor operable to present on the display an indication of a desired location for placement of the object relative to the field of view of the camera, provide an instruction guiding in the field of view of the camera placement of the object relative to the indication of desired location for placement of the object, determine a movement of the object towards the camera when it appears that the object is moving angularly away from the camera but its size is not changing materially, determine a position of the object in the field of view of the camera relative to the desired location for placement of the object based on at least the determined movement of the object towards the camera, determine a further position of the object in the field of view of the camera relative to the desired location for placement of the object, and present on the display an indication of proper positioning of the object in the field of view of the camera relative to the desired position for placement of the object.

10. The system of claim 9, wherein the object is a medication pill.

11. The system of claim 9, wherein the processor is operable to guide repeatedly placement of the object relative to the indication of desired location for placement of the object until the processor confirms that the object is properly placed.

12. The system of claim 9, wherein the processor employs the determined movement of the object towards the camera to aid in determining positioning of the object relative to the desired location for placement of the object.

13. The system of claim 9, wherein the processor is arranged to cause to be displayed on the display an image of the desired location for the placement of the object.

14. The system of claim 13, wherein the desired location for the placement of the object is displayed to a user to aid in properly placing the object.

15. The system of claim 9, wherein if the object is removed from a field of view of the camera and then repositioned within the field of view of the camera, the processor determines the first size of the object.

16. The system of claim 9, wherein the object is a free standing object.

17. The system of claim 9, wherein the processor is arranged to repeatedly provide an instruction guiding in the field of view of the camera placement of the object relative to the indication of desired location for placement of the object until the processor confirms that the object is properly placed.

18. The system of claim 9, wherein if the object is removed from a field of view of the camera and then repositioned within the field of view of the camera, the processor determines a position of the object again.
