Eye-tracker complementary restraint components

Attachements for tighter securing of a Pupil Labs eye-tracker with an elastic headband. The provided components can be manufactured with a 3D-printer (e.g. Ultimaker), and attached with nuts and bolts to the temples of the Pupil -mount, with the elastic headband tightened between the parts.

The components were developed for a series of eye-tracking experiments for a vehicle driver, that necessiated a secure fit of the eye-tracking equipment despite active head movement of the user.
