The Tobii Pro Spectrum is Tobii’s flagship screen-based eye tracker for advanced scientific research. Unlike wearable systems such as Tobii Pro Glasses 3 and Tobii Glasses X, Spectrum is designed for highly controlled laboratory experiments where maximum temporal precision and data quality are critical.
What Makes It Special?
Ultra-High Sampling Rates
Tobii Pro Spectrum can record gaze data at up to 1200 Hz (1,200 measurements per second).
This allows researchers to study:
- Micro-saccades
- Very rapid eye movements
- Pupil dynamics
- Reading behavior
- Visual attention mechanisms
- Cognitive processing
Higher sampling rates provide greater temporal accuracy, which is essential when studying events that occur within milliseconds.
Research Applications
Neuroscience
Researchers use Spectrum to investigate:
- Visual perception
- Attention mechanisms
- Cognitive workload
- Brain-behavior relationships
Psychology
Suitable for studies involving:
- Decision making
- Learning
- Memory
- Emotion
- Social cognition
Reading and Language Research
The high sampling frequency enables detailed analysis of:
- Word fixation durations
- Reading patterns
- Language processing
- Dyslexia research
Human Factors & Ergonomics
Used to evaluate:
- Interface usability
- Operator attention
- Safety-critical tasks
- Control room performance
