A projector based user interface unit is described for implanting an interactive workspace. The interface unit projects a graphical workspace onto a display surface and monitors user interactions with the workspace. A mirror is placed on or near the workspace to reflect the face of the user to the interface unit. The interface unit captures the mirrored face of the user and provides images of the face of the user to other users for use in conjunction with collaborative techniques such as video conferencing or content sharing.

Methods, systems and devices are described for determining positional information and force information for input objects using an input device. The various embodiments provide improved user interface functionality by detecting positional information and force information at a sensing surface having a configurable sub-region, and operating the input device in either a touchpad mode or a keypad mode based on whether the force information exceeds a threshold value.

A passive projection screen presents images projected thereon by a projection system. A surface of the screen includes elements that are reflective to non-visible light, such as infrared (IR) light. When non-visible light is directed to the screen, the non-visible light is reflected by the reflective elements back. Part of the reflected light may contact and reflect from a user's fingertip or hand (or other object, such as a stylus) while another part is reflected to the projection system. The projection system differentiates among distances to the surface and distances that include the additional travel to the fingertip. As the fingertip moves closer to the surface, the distances approach equality. When the distances are approximately equal, the finger is detected as touching the surface. In this manner, a projection surface equipped with reflective elements facilitates more accurate touch detection.

Input devices and methods are provided for effecting adjustment, in which a sensing system is adapted to detect motion of a first object and a second object in a sensing region and a processing system coupled to the sensing system. The processing system is adapted to detect a change in position of the first object relative to the second object, the first and second objects being simultaneously present in the sensing region, and effect a change in a parameter in response to a motion of the first object in the sensing region.
