1. A compact eye-tracking camera assembly for a computing device having a display, the eye-tracking camera assembly including:
an infrared image sensor;
a lens component; and
a mirror component;
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;
a front panel that is substantially transparent to IR light and at least partially opaque to visible light.
