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 techniques to determine a location of the touch sensitive surface corresponding to a touch by an object are described. In an example, an indication of actuation of touch sensitive surface, based on a touch, by an object, at a point on a touch sensitive surface is received. An image of the touch sensitive surface is received from an image capturing device, in response to the receiving of the indication. The touch sensitive surface has N touch sensors and the resolution of the image capturing device has an image resolution comprising "X" pixels which is greater than "N". A location of the touch sensitive surface corresponding to the touch by the object is identified based on the image.

Abstract: An example processor-implemented method for generating corners of a display area is provided. The method comprises detecting a dominant line for each side of the display area, each dominant line used to identify corners, detecting subline segments on each side of the display area, determining a distance between the corners identified by the dominant lines and the sub-line segments on each side, and generating the corners of the display area based on the distance.
