PROJECTION-BASED USER INTERFACE
First Claim
1. A computing device with a virtual touch screen, comprising:
- a projector to project a user interface image;
a depth camera to detect objects in a vicinity of the user interface image;
a touch service that receives image data from the depth camera and analyzes the image data to generate touch event data; and
a User Input (UI) device driver that receives the touch event data from the touch service and reports the touch event data to an operating system of the computing device;
wherein the touch service and UI device driver comprise system level software that is operable prior to a user logging onto the computing device.

Abstract
Techniques for providing a virtual touch screen are described. An example of a computing device with a virtual touch screen includes a projector to project a user interface image and a depth camera to detect objects in the vicinity of the user interface image. The computing device also includes a touch service that receives image data from the depth camera and analyzes the image data to generate touch event data. The computing device also includes a User Input (UI) device driver that receives the touch event data from the touch service and reports the touch event data to an operating system of the computing device. The touch service and UI device driver are system level software that is operable prior to a user logging onto the computing device.
