- presenting on a display of a device an indication of a desired location for placement of the object held in the hand of the user relative to a field of view of the camera;
displaying an indicator on the display of the device for guiding placement of the object held in the hand of the user within the field of view of the camera relative to the indication of desired location for placement of the object;
determining a position of the object in the hand of the user within the field of view of the camera relative to the desired location for placement of the object;
adjusting the indicator on the display 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;
after adjusting the indicator on the display in response to the determination of the position of the object to the desired location, determining a position of the object in the hand of the user within the field of view of the camera relative to the desired location for placement of the object; and

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.

10. A system for determining proper positioning of an object held in the hand of the user 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 in the hand of the user relative to a field of view of the camera, and to display an indicator for guiding placement of the object held in the hand of the user relative to the field of view of the camera so that the display of the object is guided towards the indication of the desired location; 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 held in the hand of the user relative to the field of view of the camera, display an indicator on the display guiding in the field of view of the camera placement of the object held in the hand of the user relative to the indication of desired location for placement of the object, determine a position of the object in the hand of the user in the field of view of the camera relative to the desired location for placement of the object, adjust the indicator on the display 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 towards the desired location, determine a position of the object in the hand of the user 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 hand of the user in the field of view of the camera relative to the desired position for placement of the object. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
