TL;DR
This paper introduces a statistical model for Ticker, a probabilistic stereophonic single-switch text entry system designed to improve communication for visually impaired users with motor disabilities.
Contribution
It develops a new probabilistic model specifically tailored for Ticker, enhancing single-switch text entry efficiency for users with visual and motor impairments.
Findings
Improved text entry accuracy for visually impaired users
Enhanced efficiency of single-switch communication
Validated through experimental results
Abstract
This paper presents the statistical model for Ticker [1], a novel probabilistic stereophonic single-switch text entry method for visually-impaired users with motor disabilities who rely on single-switch scanning systems to communicate. All terminology and notation are defined in [1].
