Final Prototype of Gaze Glasses

The final design of the gaze glasses uses tie-on mechanism for both cameras.

The main objective of the Gaze Glasses project was to redesign the PUPIL eye tracker headset to make it adaptable for different head shapes and adjustable for different users. A re-sizing of the PUPIL headset was initially proposed, but it was rejected in favor of tie-on camera mount design which would fit onto readily-available consumer glasses. The tie-on mounts are two L-bracket that sandwich and attach onto glasses frames, and these mounts are 3D printed out of acrylic. Gooseneck tubing with a diameter of 4.75 mm was used to connect the camera mounts to the arm mounts, which in turn were attached to the temple of the glasses. This design allows for the Gaze Glasses to be used on a wide variety of head shapes and sizes.

Gaze Glasses Performance:

• The assembly of the Gaze Glasses proved that the arm mounts stay in place and moves along with the glasses frame as if it is one unit, indicating that the two L-bracket design of the arm mount stays stable.

• Both the eye and the scene cameras have been recognized by the software without major adjustment.

• The gooseneck tubing held the required weight of the eye camera assembly, and stayed in fixed position relative to the eye.
