Fast Hands-free Writing by Gaze Direction

TL;DR

This paper introduces a gaze-based text entry method using inverse arithmetic coding, which is faster and more accurate than traditional on-screen keyboards by leveraging eye capabilities and language modeling.

Contribution

It presents a novel gaze-based writing system that combines inverse arithmetic coding with language models to improve speed and accuracy.

Findings

Faster text entry compared to on-screen keyboards

Higher accuracy in gaze-based writing

Effective use of language models for predictability

Abstract

We describe a method for text entry based on inverse arithmetic coding that relies on gaze direction and which is faster and more accurate than using an on-screen keyboard. These benefits are derived from two innovations: the writing task is matched to the capabilities of the eye, and a language model is used to make predictable words and phrases easier to write.
