Combining Low-Cost Eye Trackers for Dual Monitor Eye Tracking
The increasing use of multiple screens in everyday use creates a demand for multi-monitor eye tracking. Current solutions are complex and for many use cases prohibitively expensive. By combining two, low-cost single monitor eye trackers, we have created a dual monitor eye tracker requiring only minor software modifications from the single monitor version. The results of a user study, which compares the same eye trackers in a single monitor and a dual monitor setup, show that the combined system can accurately estimate the user’s gaze across two screens. The presented approach gives insight into low-cost alternatives for multi-monitor eye tracking and provides a basis for more complex setups, incorporating even more screens.
