Touchless interactive display system

A method for touchless interaction with a display, the method comprising the steps of:

• providing a display area defined by a boundary of a display, a reflective surface located along a portion of the boundary and perpendicular to a surface of the display, and one optical sensor disposed opposing the reflective surface, wherein the optical sensor faces the reflective surface and has a primary field of view towards the reflective surface and a secondary filed of view reflected back from the reflective surface, wherein the primary field of view covers a first portion of the display area less than the whole display area, and the secondary field of view covers a second portion of the display area, such that the first and second portions of the display area cover the entire display area;
• and
• detecting an object placed within at least one of its first and second fields of view without having the object touch the display.

A touchless interactive display system, comprising:

• a display with a display area defined by a boundary of the display;
• one depth camera, wherein the depth camera has a field of view that covers the entire display area;
• and a processor coupled with the depth camera and the display, wherein the depth camera and processor are operable to detect an object placed within the field of view without having the object touch the display.
