Patent Images
1. A method for determining proper positioning of an object relative to a camera, comprising:
- presenting, on a display, 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; and
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.

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.

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, and 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18)
