Abstract
In some examples, a projector is controlled to project an image content onto a projection surface in a region defining a display area. Captured images are received that are captured by at least one optical sensor of the projected image content on the projection surface. In the captured images, user touches of a plurality of designated locations of the projected image content on the projection surface are detected. A position of an interaction area based on the detected user touches is determined, and, based on the determined position of the interaction area, it is determined whether the display area and the interaction area coincide.
Claims17
A method, comprising:
- performing by at least one processor:
- controlling a projector to project an image content onto a projection surface in a region defining a display area;
- receiving captured images captured by at least one optical sensor, the received captured images comprising at least a portion of the projected image content on the projection surface;
- detecting, in the captured images, user touch interactions with designated elements of the projected image content on the projection surface;
- determining a position of an interaction area based, at least in part, on the detected user touch interactions, wherein determining the position of the interaction area is based, at least in part, on detecting the user touch interactions at a plurality of corners of the projected image content;
- and
- determining, based on the determined position of the interaction area, whether the display area and the interaction area coincide.
A display system, comprising:
- a projector;
- and
- at least one processor to:
- control the projector to project an image content onto a display area of a projection surface;
- receive captured images captured by at least one optical sensor, the received captured images to comprise at least a portion of the projected image content on the projection surface;
- detect, in the captured images, user touch interactions with designated elements of the projected image content on the projection surface;
- determine a position of an interaction area based, at least in part, on the detected user touch interactions, wherein to determine the position of the interaction area comprises detection of the user touch interactions at a plurality of corners of the projected image content;
- and
- determine, based on the determined position of the interaction area, whether the display area and the interaction area coincide.
A non-transitory machine-readable storage medium encoded with instructions executable by at least one processor to:
- control a projector to project an image content onto a display area of a projection surface;
- receive captured images captured by at least one optical sensor, the received captured images to comprise at least a portion of the projected image content on the projection surface;
- detect, in the captured images, user touch interactions with designated elements of the projected image content on the projection surface;
- determine a position of an interaction area based, at least in part, on the detected user touch interactions, wherein determination of the position of the interaction area is further to comprise determination of the position of the interaction area based on detection of the user touch interactions at a plurality of corners of the projected image content;
- and
- determine, based on the determined position of the interaction area, whether the display area and the interaction area coincide.
