1. A method for determining an indication of interaction in a direction towards a webcam, comprising the steps of:
- determining an object in a region of interest;
determining a first size of the object in the region of interest;
tracking the object in the region of interest;
determining a second size of the object in the region of interest; and
confirming that a push interaction has taken place if the ratio of the second size to the first size is greater than a predetermined value.

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.

12. A method for determining an indication of interaction in a direction towards a webcam, comprising the steps of:
-
determining an object in a region of interest; determining a first size of the object in the region of interest at a first time; tracking the object in the region of interest; determining a second size of the object in the region of interest at a second time; determining a third size of the object in the region of interest at a third time; and confirming that a push interaction has taken place if the ratio of the second size to the first size is greater than a first predetermined value, and the ratio of the third size to the first size is greater than a second predetermined value. - View Dependent Claims (13, 14, 15, 16)

17. A method for determining an indication of interaction in a direction towards a webcam, comprising the steps of:
-
determining an object in a region of interest; locating one or more distinguishing features of the object in the region of interest at a first time; tracking the object in the region of interest; locating the one or more distinguishing features of the object in the region of interest at a second time; determining a relative positioning of the distinguishing features of the object between the first and second time; and confirming that a push interaction has taken place based upon the determined relative positioning. - View Dependent Claims (18)

19. A system for determining an indication of interaction in a direction towards a webcam, comprising:
-
a webcam for capturing one or more images; and a processor for processing the one or more captured images, the processor determining an object in a region of interest of the one or more captured images, determining a first size of the object in the region of interest at a first time;
tracking the object in the region of interest, determining a second size of the object in the region of interest at a second time;
determining a third size of the object in the region of interest at a third time, and confirming that a push interaction has taken place if the ratio of the second size to the first size is greater than a first predetermined value, and the ratio of the third size to the first size is greater than a second predetermined value. - View Dependent Claims (20)
