key considerations Neon is a modular eye tracker which consists of the Neon Module (eye tracking hardware) and a frame which can be switched out. There are frames available for many different use cases making it a very flexible eye tracking system.	key considerations • Post-import only • Fully compatible with iMotions’ analysis tools.	key considerations • Post-import only • Fully compatible with iMotions’ analysis tools. • Solid frame for Industrial research situations	key considerations • Post-import only • Fully compatible with iMotions’ analysis tools. • Custom-printed children’s sizes. • Mobile recording available with Android devices.
