Abstract: A system includes a sensor to capture multiple images of a portion of a first object illuminated by coherent illumination and a time of capture of each of the images; and a processor to compare two images of the multiple images to identify one or more touch points. Each touch point has a difference in value between the two images that is greater than a threshold. Upon determining a spatial shape formed by the identified touch points that corresponds to a pointing end of a pointing object, the system provides at least one of: i) a touch location of the pointing end relative to the first object, where the touch location is based on the spatial shape formed by the identified touch points, or ii) the time of capture of a second image of the two images that produced the spatial shape.

Abstract: A method and system to make virtual changes to a real object is disclosed. Three-dimensional visual data regarding the object is received from a sensor cluster module, which tracks the location and orientation of the object. A three-dimension reconstructed model of the object is created from the visual data. User-selected virtual changes to the object are applied to the three-dimension reconstructed model. A two-dimensional image of the changes to the three-dimensional reconstructed model is projected with a projector onto the object in its current location and orientation.

Abstract: An example method is provided for. The method comprises receiving an image of an object on a surface, detecting features of the object, and presenting the image on the surface based on the features of the object. The features include location and dimensions, wherein dimensions of the image match the dimensions of the object and location of the image overlap with the location of the object on the surface.

Abstract: A projection system includes a video projector to project images having an image region on a surface having a border area associated with the surface, and a processing system including a graphical processing unit to evaluate the border area and the projected image region, the graphical processing unit to transform the projected image region into an aligned projected image region coinciding with the border area.

Abstract: Examples disclosed herein describe, among other things, a computing system. The computing system may include, for example, a touch-sensitive surface to obtain a capacitive signature representing an object disposed on the touch-sensitive surface, and a camera to obtain supplemental data representing the object. The system may also include an identification engine to obtain, based at least on the capacitive signature, identification data associated with the object, and to obtain, based at least on the supplemental data, at least one characteristic of the object.
