TOUCHLESS TABLET METHOD AND SYSTEM THEREOF
First Claim
1. A touchless tablet comprising:
- a sensing unit for identifying a touchless finger action above a form; and
a controller communicatively coupled to said sensing unit, wherein said controller associates said finger action with at least one form component on said form,wherein said touchless tablet identifies a selection of said form component based on said location and action of said finger above said form.

Abstract
A system (100) and method for a touchless tablet that produces a touchless sensory field over a form (111). The touchless tablet includes a touchless sensing unit (110) for identifying a finger action above the form, and a controller (130) communicatively coupled to the sensing unit for associating the finger action with at least one form component on the form. The touchless tablet identifies a selection of a form component (122) based on a location and action of the finger above the form. A display (140) connected to the touchless tablet can expose a graphical application, wherein a touchless selection of a form component corresponds to a selection of a graphical component on the graphical application.
