Our approach integrates a multidirectional point-select task to characterize cursor control over time, distance, and direction. The characterization is automatically employed to develop a computationally efficient keyboard layout that prioritizes each user\u2019s movement abilities through capturing directional constraints and preferences. We evaluated our approach in a study involving 16 participants using inertial sensing and facial electromyography as an access method, resulting in significantly increased communication rates using the personalized keyboard (52.0 bits\/min) when compared to a generically optimized keyboard (47.9 bits\/min). Our results demonstrate the ability to effectively characterize an individual\u2019s movement abilities to design a personalized keyboard for improved communication. This work underscores the importance of integrating a user\u2019s motor abilities when designing virtual interfaces.<\/jats:p>","DOI":"10.3390\/mti6080067","type":"journal-article","created":{"date-parts":[[2022,8,3]],"date-time":"2022-08-03T23:33:01Z","timestamp":1659569581000},"page":"67","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Ability-Based Methods for Personalized Keyboard Generation"],"prefix":"10.3390","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8670-1761","authenticated-orcid":false,"given":"Claire L.","family":"Mitchell","sequence":"first","affiliation":[{"name":"Delsys, Inc., Natick, MA 01760, USA"},{"name":"Altec, Inc., Natick, MA 01760, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5279-7336","authenticated-orcid":false,"given":"Gabriel J.","family":"Cler","sequence":"additional","affiliation":[{"name":"Department of Speech and Hearing Sciences, University of Washington, Seattle, WA 98105, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Susan K.","family":"Fager","sequence":"additional","affiliation":[{"name":"Institute of Rehabilitation Science and Engineering, Madonna Rehabilitation Hospital, Lincoln, NE 68506, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Paola","family":"Contessa","sequence":"additional","affiliation":[{"name":"Delsys, Inc., Natick, MA 01760, USA"},{"name":"Altec, Inc., Natick, MA 01760, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Serge H.","family":"Roy","sequence":"additional","affiliation":[{"name":"Delsys, Inc., Natick, MA 01760, USA"},{"name":"Altec, Inc., Natick, MA 01760, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gianluca","family":"De Luca","sequence":"additional","affiliation":[{"name":"Delsys, Inc., Natick, MA 01760, USA"},{"name":"Altec, Inc., Natick, MA 01760, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joshua C.","family":"Kline","sequence":"additional","affiliation":[{"name":"Delsys, Inc., Natick, MA 01760, USA"},{"name":"Altec, Inc., Natick, MA 01760, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0583-0228","authenticated-orcid":false,"given":"Jennifer M.","family":"Vojtech","sequence":"additional","affiliation":[{"name":"Delsys, Inc., Natick, MA 01760, USA"},{"name":"Altec, Inc., Natick, MA 01760, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"444","DOI":"10.1080\/02687038.2013.772293","article-title":"Mobile computing technology and aphasia: An integrated review of accessibility and potential uses","volume":"27","author":"Brandenburg","year":"2013","journal-title":"Aphasiolog"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"57","DOI":"10.1016\/j.procs.2014.02.008","article-title":"Accessibility to Mobile Interfaces for Older People","volume":"27","author":"Moreno","year":"2014","journal-title":"Procedia Comput.
