Selectable projector and imaging modes of display table
First Claim
1. A method for enabling a user to selectively operate a display table in one of two different modes, including a first mode in which a video image is projected on a display surface of the display table and a second mode in which the video image is projected onto a separate surface that is not part of the display table, comprising the steps of:
- (a) enabling the user to selectively change a projection light path for the video image between a first path that is used when operating the display table in the first mode, and a second path that is used when operating display table in the second mode; and
(b) projecting the video image along the projection path selected by the user so that the video image is viewed on one of the display surface and the separate surface, in accord with the one of the first path and the second path selected by the user.

Abstract
A display table contains a projector that can either project an image onto a display surface of the display table or onto an external surface that is separate from the display table. A user can change the path of the light from the projector from the display surface to the external surface, either by rotating the projector to an appropriate position, or by moving a mirror into the path of light from the projector. A video camera included in the display table also has dual functionality and can selectively be used either to image objects on or above the display surface, or objects that are not adjacent to the display surface. A panel in the housing of the table is opened, and either the video camera is pivoted or a mirror is moved into its light path. Imaging a user with the video camera is useful for video conferencing.

9. A system that enables a user to selectively determine where a video image is projected, comprising:
-
(a) a display surface supported by a housing;
(b) a projector supported by the housing, said projector projecting a video image along a light path; and
(c) means for enabling a user to change the system between a first mode and a second mode of operation by altering the light path, wherein in the first mode, the projector projects the video image onto the display surface, and in the second mode, the projector projects the video image onto a separate surface that is spaced apart from the housing. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)
