The Vocal Joystick: Evaluation of Voice-based Cursor Control Techniques
This paper presents the Vocal Joystick, a system that enables continuous mouse cursor control through vocal parameters — specifically vowel quality, loudness, and pitch. Unlike traditional speech recognition systems that process discrete commands ("m…

Non-speech Input and Speech Recognition for Real-time Control of Computer Games
This paper compares two acoustic input methods — speech recognition and non-speech humming — for controlling the arcade game Tetris in real time. The motivation is that while turn-based and strategic games are not greatly affected by motor impairment…

Alternative Text Entry Using Different Input Methods
This paper presents the HaMCoS (Hands-free Mouse Control System) framework and its text entry applications, designed for people who cannot use their hands to operate a keyboard. HaMCoS works by detecting intentional muscle contractions — specifically…

Indirect Text Entry Using One or Two Keys
This paper introduces a new descriptive model for indirect text entry — text composition methods where the number of input devices (switches) is significantly smaller than the number of selectable characters. This is the primary text entry paradigm f…
