Claim 5:
6. A tablet computing device comprising:
an enclosure;
a display coupled to enclosure; and
an eye-tracking camera assembly incorporated into the display, the eye-tracking camera assembly including: an infrared image sensor; a lens component;
and a mirror component;
a front panel that is substantially transparent to IR light and at least partially opaque to visible light;
wherein the infrared image sensor, lens component, and mirror component are substantially collinear along a principal axis; and 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 and a second angle of approximately 15 to 22 degrees relative to a second axis that is orthogonal to the first axis, the first and second axes being substantially parallel to a plane defined by the display.
