3.2 How the Chin Rest works
The Chin Rest is used to hold a participant’s head in place when conducting eye tracking
experiments with screen-based eye trackers.
The Chin Rest can be mounted on a tabletop up to 50 mm thick using the clamp at the base of
the assembly. After firmly attaching the Chin Rest on the tabletop, the chin support and the
forehead support can be adjusted vertically along the entire length of the posts. This ensures a
comfortable fit for each participant while holding the head in place during the entire experiment.

The Chin Rest is designed to be fully adjustable for comfort. The forehead support has a 10°
angle for a comfortable positioning of the participants forehead. The chin cup is adjustable on the
chin support in a front and back direction by +/- 5 mm, with the help of the knob under the chin
cup. This allows for different chin and head shapes and sizes.
No tools are needed for attaching the Chin Rest or for adjusting the movable parts.
The knobs should be tightened firmly by hand. For the side knobs, adjust both sides at
the same time.
The Chin Rest base has rubber pads to protect the tabletop. To ensure minimal tilt of
the Chin Rest when the participant leans forward, consider reducing the overall
elasticity of the setup. You can do this by using a sturdy tabletop and by removing the
rubber pads from the Chin Rest base.
Overtightening the adjustment knobs can cause damage to the related components.
