Claim 10:
11. A method of manufacturing a tablet computing device, the method comprising:
providing an enclosure;
providing a display;
forming an eye-tracking camera assembly including an infrared image sensor, a lens component, a front panel that is substantially transparent to IR light and at least partially opaque to visible light, and a mirror component, all of which are substantially collinear along a principal axis;
interconnecting the enclosure, display, and eye-tracking camera assembly such that such that the mirror component is oriented at a compound angle configured to redirect incident IR light along the principal axis, the compound angle characterized by a first angle of approximately 45 degrees relative to a first axis substantially parallel to a plane defined by the display, and a second angle of approximately 15-22 degrees relative to a second axis that is orthogonal to the first axis, wherein the second axis is substantially parallel to the plane defined by the display.
