ABSTRACT
Dasher is one of the best known inventions in the area of text entry in recent years. It can be used with many input devices, but studies on user performance with it are still scarce. We ran a longitudinal study where 12 participants transcribed Finnish text with Dasher in ten 15-minute sessions using a Tobii 1750 eye tracker as a pointing device. The mean text entry rate was 2.5 wpm during the first session and 17.3 wpm during the tenth session. Our results show that very high text entry rates can be achieved with eye-operated Dasher, but only after several hours of training.

EyeSwipe: Dwell-free Text Entry Using Gaze Paths
CHI '16: Proceedings of the 2016 CHI Conference on Human Factors in Computing SystemsText entry using gaze-based interaction is a vital communication tool for people with motor impairments. Most solutions require the user to fixate on a key for a given dwell time to select it, thus limiting the typing speed. In this paper we introduce ...
Fast gaze typing with an adjustable dwell time
CHI '09: Proceedings of the SIGCHI Conference on Human Factors in Computing SystemsPrevious research shows that text entry by gaze using dwell time is slow, about 5-10 words per minute (wpm). These results are based on experiments with novices using a constant dwell time, typically between 450 and 1000 ms. We conducted a longitudinal ...
Leyenes: A gaze-based text entry method using linear smooth pursuit and target speed
AbstractGaze-based writing is one of the most widespread eye tracking applications for human–computer interaction. While eye tracking communication has traditionally been employed as an assistive technology, declining prices of eye trackers now make it a ...
Highlights- Leyenes is a new gaze-based writing method that exploits linear smooth pursuit.
- The interface consists of a series of targets moving along linear paths.
- Leyenes does not require any explicit calibration by the user.
