Hypothesis
How do the performance and usability of a mobile eye-tracker compare to stationary eye-trackers?
Conclusion
The mobile eye-tracker can reliably measure basic eye-movement parameters, while the stationary eye-tracker provides high-resolution data.
Supporting Evidence
- The mobile eye-tracker (TOM-rm) is suitable for basic eye movement data collection.
- The stationary eye-tracker (TOM-rs) provides high-resolution data.
- Data quality was affected by the need for compromises in experimental conditions.
Takeaway
This study looked at how well a new mobile eye-tracker works compared to two stationary ones. The mobile one is good for simple tasks, while the stationary ones are better for detailed measurements.
Methodology
Participants performed pro- and anti-saccade tasks and free-viewing tasks while their eye movements were recorded by three different eye-trackers.
Potential Biases
Potential bias due to the exclusion of data from subjects who could not be reliably tracked.
Limitations
The experimental conditions could not be optimized for all three eye-trackers simultaneously, affecting data quality.
Participant Demographics
30 participants (16 male, 14 female) with a mean age of 24.86 years.
