• QC Speller: User Interface Design of a Hands-Free Touch-Free Speller with Brain Electroencephalogram Sensory Rhythm

  Tulika Nama, Debasis Samanta (2025) — ACM Transactions on Accessible Computing

  This paper presents QC Speller, a novel brain-computer interface (BCI) text entry system designed for people with severe motor impairments who cannot use traditional keyboards, mice, or touchscreens. The system uses electroencephalography (EEG) to de…

• EEG as a means of communication: preliminary experiments in EEG analysis using neural networks

  Charles W. Anderson, Saikumar V. Devulapalli, Erik A. Stolz (1994) — Proceedings of the First Annual ACM Conference on Assistive Technologies (Assets '94)

  This paper explores the use of electroencephalography (EEG) as a communication channel for paralyzed individuals, representing early brain-computer interface (BCI) research. The core premise is that if distinct mental states can be reliably identifie…
