1. A system for sensing touch detection, the system comprising: a memory; a processing unit coupled to the memory; an object sensing component executed by the processing unit and configured to sense and to detect an object over an interactive surface, the interactive surface being illuminated with an infrared source; a shadow analysis component executed by the processing unit and configured to track a shadow of the object appearing on the interactive surface based on the interactive surface reflecting infrared when the object is moving; and the shadow analysis component executed by the processing unit and further configured to enable touch detection by examining the shadow of the object to determine if the object is hovering over or touching the interactive surface based on an analysis of the shadow of the object.
