    Abstract: Examples disclosed herein relate to aligning content displayed from a projector on to a touch sensitive mat. Examples include detecting a border of the mat, wherein the mat includes a surface area of a first spectral reflectance characteristic on to which the projector is to project the content, and the border of a second spectral reflectance characteristic different from the first spectral reflectance characteristic surrounding a perimeter of the surface area. As an example, detecting the border of the mat generally includes differentiating the second spectral reflectance characteristic of the border from the first spectral reflectance characteristic of the surface area. Examples include detecting a border of the content displayed on to the mat, and adjusting projector settings for the border of the content displayed on to the mat to fit within the detected border of the mat.

    Abstract: Examples disclosed herein relate to manipulating three-dimensional image in response to user gestures. Examples include rendering three-dimensional images based on three-dimensional image data, receiving sensor data corresponding to a user gesture, and recognizing the user gesture based on the sensor data Based on the recognized user gesture and the three-dimensional image data, determining and performing a function to update the corresponding three-dimensional image data and, consequently, alter the rendered three-dimensional images. The three-dimensional image data can be generated by a sensor coupled to the same computing device used to render the three-dimensional images.

    Abstract: Examples disclosed herein describe, among other things, a computing system. The computing system may in some examples include a touch-sensitive surface, a display, and at least one camera to capture an image representing an object disposed between the camera and the touch-sensitive surface. The computing system may also include a detection engine to determine, based at least on the image, display coordinates, where the display coordinates may correspond to the object's projection onto the touch-sensitive surface, and the display is not parallel to the touch-sensitive surface. In some examples, the detection engine is also to display an object indicator at the determined display coordinates on the display.

    Abstract: A plurality of homography operators define respective mappings between pairs of coordinate spaces, wherein the coordinate spaces include a coordinate space of a first visual sensor, a virtual coordinate space, and a coordinate space of a second visual sensor. Calibration between the first and second visual sensors is provided using the plurality of homography operators.
