Abstract

A projective touch apparatus includes a rail base, a plate standing vertically on the rail base, an optical touch module, a platform slidably disposed through a rail structure of the rail base, a projector, and a host. The optical touch module is disposed on the plate for positioning a touch position of a touch object on a touch surface of the plate. The projector is disposed on the platform and located under the plate, to move with sliding of the platform to a projecting position for projecting an image to the touch surface or a back surface of the plate, or to a containing position to be contained on the rail base. The host is disposed in the rail base for controlling the projector to project the image and for performing a touch operation of the touch object on the touch surface according to the touch position and the image.

Dependent claims

A projective touch apparatus comprising:

a rail base having a rail structure;
a plate standing vertically on the rail base and having a touch surface and a back surface opposite to the touch surface;
an optical touch module disposed on the plate for positioning a touch position of at least one touch object on the touch surface;
a platform slidably disposed through the rail structure;
a projector disposed on the platform and located under the plate for moving with sliding of the platform along the rail structure to a projecting position to project an image to the touch surface or a back surface of the plate, or to a containing position to be contained on the rail base;
and
a host disposed in the rail base and electrically connected to the projector and the optical touch module for controlling the projector to project the image and for performing a touch operation of the at least one touch object on the touch surface according to the touch position of the at least one touch object and the image.
