    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: A digital light projector having a plurality of color channels including at least one visible color channel providing visible light and at least one invisible color channel providing invisible light. The digital light projector including a projecting device projecting light from the plurality of color channels onto an environment in the form of an array of pixels which together form a video image including a visible image and an invisible image, the video image comprising a series of frames with each frame formed by the array of pixels, wherein to form each pixel of each frame the projecting device sequentially projects a series of light pulses from light provided by each of the plurality of color channels, with light pulses from the at least one visible color channel forming the visible image and light pulses from the at least one invisible color channel forming the invisible image.
