Touch sensitive mat of a system with a projector unit
First Claim
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.

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.

8. A method to align content displayed from a projector on to a touch sensitive mat, the method comprising:
-
detecting a border of the mat, wherein the mat includes a surface area of a first spectral reflectance characteristic (SRC) on to which the projector is to project the content and the border of a second SRC surrounding a perimeter of the surface area, and wherein detecting the border of the mat comprises differentiating the second SRC of the border from the first SRC of the surface area, wherein; a computing device attaches to the projector via a coupling member of the projector; the computing device blocks a view of the projector when viewing the computing device from a viewing angle facing a display on a front side of the computing device; detecting a border of the content displayed on to the mat; adjusting projector settings for the border of the content displayed on to the mat to fit within the detected border of the mat; detecting corners of the touch sensitive surface; detecting corners of the projector display space; and determining a correspondence between the two sets of corners, based, at least in part, on homography. - View Dependent Claims (9, 10, 11)
