1. A mobile tablet computer system comprising: a tablet computer chassis; a touchscreen display contained within the chassis, the touchscreen display including a surface with a surface linear polarizing filter; a first arm and a second arm, a first end of the first arm being coupled with the chassis at a first location and a first end of the second arm being coupled with the chassis at a second location different from the first location, the first and second arms being extended upright from the first and second locations respectively relative to the touchscreen display surface; a first camera positioned for a first camera view to capture visual data within a first target area, the first target area to include a first sub-area that includes the touchscreen display surface and a second sub-area that does not include the touchscreen display surface, the second sub-area being outside of and not on top of the touchscreen display surface, wherein the first camera is coupled with a second end of the first arm and includes a first linear polarizing filter to block view of the touchscreen display by the first camera; a second camera positioned for a second camera view different from the first camera view to capture visual data within a second target area, the second target area to include a first sub-area that includes the touchscreen display surface and a second sub-area that does not include the touchscreen display surface, the second sub-area being outside of and not on top of the touchscreen display surface, wherein the second camera is coupled with a second end of the second arm and includes a second linear polarizing filter to block view of the touchscreen display by the second camera, the second sub-area of the first target area and the second sub-area of the second target area including an overlapping target area visible by both the first camera view and the second camera view, wherein the mobile tablet computer system is to be calibrated such that an object viewed by first camera view and the second camera view in the overlapping target area is reported as a single object; a processor; and software to be executed via the processor to: generate a first graphical image to be displayed on the touchscreen display, identify, from the captured visual data from the first camera and the second camera, a physical object other than the touchscreen display surface that is within the first target area visible to the first camera or the second target area visible to the second camera, including the overlapping target area visible to both the first camera and the second camera, determine coordinates of a location of the detected physical object using the first view of the first camera, the second view of the second camera, or both the first view of the first camera and the second view of the second camera, process an interaction between the physical object and the first graphical image, said interaction being based upon one or more of location, height, velocity, acceleration, gesture, and physical orientation of the physical object in the overlapping target area with respect to the first graphical image, and generate and display a second graphical image on the touchscreen display, the second graphical image including a graphical representation of the interaction between the physical object and the first graphical image.
