Problems solved by technology

However, because direct touch of the display surface requires placing the hand between the user's eyes and the surface, it is not possible to prevent all occlusions

Embodiment Construction

[0028] reverse touch table

[0029] Figure 2 illustrates a direct touch sensitive display system according to one embodiment of the present invention. The system includes a workbench 210 with a display surface 220, one or more chairs 240, a projector 250, and a processor 260, with a touch-sensitive surface 230 mounted on the back of the display surface. For convenience, the table 210 is placed on the auxiliary support surface 211 .

[0030] As used throughout, "front" means on the side facing the user, and "rear" means the opposite side facing away from the user. For desktop installations, these correspond to "top" and "bottom".

[0031] Touch-sensitive surface 230 is geometrically identical to display surface 220 . That is, there is a one-to-one correspondence between locations on the touch-sensitive surface and locations on the display surface, making the input device a direct touch input device.

[0032] To allow the user to maintain the feeling of direct touch input wh...

Abstract

A direct touch-sensitive input device includes a display surface configured to display images on a front of the display surface, and a direct touch-sensitive surface mounted on a back of the display surface. The display surface and the direct touch-sensitive surface are geometrically coincident. The device can also include a touch-sensitive surface mounted on the front of the device.

Description

technical field [0001] The present invention relates generally to input devices for computer systems, and more particularly to touch-sensitive input devices. Background technique [0002] There are basically two types of touch-sensitive input devices: indirect touch and direct touch. One example of an indirect touch input device is the touchpad on a laptop computer. Here, the touch surface does not coincide with the display surface or screen: typically, the touch-sensitive surface is arranged in a horizontal plane, while the display surface is substantially vertical. Additionally, the aspect ratio (ie, the ratio of the horizontal dimension to the vertical dimension) of most indirect input devices is different from the aspect ratio of the display surface. This lack of uniformity makes these types of devices indirect touch input devices. As an advantage, touching the surface does not obscure the display surface from the direction of the user. [0003] There are basically t...
