Development of a Manually Operated Communication System (MOCS) for patients in intensive care units

Augment Altern Commun. 2021 Dec;37(4):261-273. doi: 10.1080/07434618.2021.2016958. Epub 2022 Jan 13.


Nonvocal alert patients in the intensive care unit (ICU) setting often struggle to communicate due to inaccessible or unavailable tools for augmentative and alternative communication. Innovation of a hand-operated non-touchscreen communication system for nonvocal ICU patients was guided by design concepts including speech output, simplicity, and flexibility. A novel communication tool, the Manually Operated Communication System (MOCS), was developed for use in intensive care settings with patients unable to speak. MOCS is a speech-output technology designed for patients with manual dexterity impairments preventing legible writing. MOCS may have the potential to improve communication for nonvocal patients with limited manual dexterity.
