What is gaze-based interaction?brief introduction to eye-tracking
![Page 6: Technical Innovation of the Day](https://reader036.fdocuments.net/reader036/viewer/2022062705/5563be6bd8b42a38198b553d/html5/thumbnails/6.jpg)
Gaze-based Interaction
Interaction simply by looking at the screen
Eye movement replaces mouse movement
Can be combined with traditional interaction
![Page 7: Technical Innovation of the Day](https://reader036.fdocuments.net/reader036/viewer/2022062705/5563be6bd8b42a38198b553d/html5/thumbnails/7.jpg)
Eye-Tracking
Reflecting invisible infrared light onto an eye
Recording reflection pattern with sensor system
Calculating exact point of gaze

Relevance of gaze-based interaction?motivation and expectations
![Page 9: Technical Innovation of the Day](https://reader036.fdocuments.net/reader036/viewer/2022062705/5563be6bd8b42a38198b553d/html5/thumbnails/9.jpg)
Advantages of Gaze-based Interaction*
Gaze jumps directly to points of interest
Gaze preludes manual selection with mouse or keyboard
Requires no physical movement or hand-eye coordination
*in a graphical operating system
