Abstract:
In a projection-type video display device that displays an image by projecting the image onto a projection object starting from a desk surface, a display screen on which a position and a gesture operation of a user are reflected is displayed in a predetermined area. An illumination and a camera are disposed in the projection-type video display device installed on the desk surface, a gesture using user's fingers is detected, and, for example, a menu screen and an operation guide are displayed according to the gesture. The shadows of the fingers are photographed by the camera, and a gesture is detected. According to the gesture, the display screen is moved, rotated, divided, or enlarged/reduced, or a menu screen is displayed. The display direction is determined in consideration of the direction of sides of the desk.

Claim (Index 1):
A projection-type video display device comprising:\n a video projector that projects a video; at least one light source that emits illumination light different from that of the projected video onto a surface at least partly overlapping a video projection surface onto which the video projector projects the video; an image capture device that performs imaging using reflected light of the illumination light; and a control system including a circuit board and being configured to execute software instructions, wherein the control system: detects at least a position at which an operator's finger is brought into contact with the video projection surface based on a captured image acquired by the image capture device; and performs a plurality kinds of operations such that at least one partial video included in the video projected by the video projector is changed based on a result of the detection acquired by the control system, wherein, the plurality kinds of operations includes: a first operation in which the control system divides a first partial video of video projected by the video projector and generates a plurality of new partial videos if the control system detects that the operator's finger moves into the first partial video from outside of the first partial video and traverses the partial video while being brought into contact with the video projection surface; and a second operation in which the control system moves a second partial video of video projected by the video projector if the control system detects that the operator's finger moves from a start position in the second partial video while being brought into contact with the video projection surface.
