The eyes have it – Studying human behavior
Studying the complexities of human behavior, whether in the lab or in natural environments, requires data collection methods that are discrete as well as accurate.
Eye and gaze tracking solutions can assist in monitoring on-screen eye movements in reading, following verbal directions in finding objects, and saccades/anti-saccades based on read or verbal instructions for both the qualitative and quantitative observation of the following behavioral areas:
- Reading & dyslexia
- Language processing
- Sentence building, etc.
- Image processing
- Auditory processing
- Interpretation & symbolism
- Mental health disorders
Since it is finding increasing application in ever more demanding environments and situations, the optimum use of eye tracking with screen-based visual stimulation requires contact-free tracking allowing free head motion, fast and easy configuration, deployment and operation, as well as accurate and reliable data in real-time. The equipment also needs to be versatile and compatible with other systems.

Research of word recognition while using Hi-speed Eyetracking with EEG
Researchers from the Institute of Psychology at the Humboldt University of Berlin, Germany, show that reliable fixation-locked ERPs can be recorded in active vision tasks that closely resemble everyday left-to-right reading. Simultaneous recordings therefore provide a useful tool to study the temporal dynamics of word recognition in natural contexts. Eye movements were recorded using the iView X™ Hi-Speed eye-tracking system, and EEG signals were recorded using the BrainVision 64-channel EEG system.
