1. A system, comprising:

  • a support structure including a base, an upright member extending upward from the base, and a cantilevered top extending outward from the upright member and including a fold mirror and sensors;

    a projector unit attachable to the upright member;

    a computing device attachable to the projector unit, wherein;

    the computing device attaches via a coupling member of the projector unit;

    the computing device blocks a view of the projector unit when viewing the computing device from a viewing angle facing a display on a front side of the computing device; and

    a touch sensitive mat communicatively coupled to the computing device, wherein;

    the mat includes a surface area of a first spectral reflectance characteristic (SRC) on to which the projector is to project an image and a border of a second SRC surrounding a perimeter of the surface area;

    the projector is to project the image upward to reflect off the mirror and on to the mat;

    the image projected onto the mat is different than the image displayed on a screen of the computing device; and

    wherein the computing device is to cause;

    the sensors to detect the border of the mat by differentiating the second SRC of the border of the mat from the first SRC of the surface area of the mat;

    the sensors to detect a border of the image reflected on to the mat; and

    the projector to adjust settings for the border of the image reflected on to the mat to fit within the detected border of the mat.
