Modern product design tends to be more intelligent and multi-functional than in the past, with the popularization of intelligent concepts. This supports the design of a new, fully functional, intelligent wheelchair that can assist people with lower limb disabilities in their day-to-day life. Based on the UCD (user-centered design) concept, this study focused on the needs of people with lower limb disabilities. Accordingly, the demand for different functions of intelligent wheelchair products was studied through a questionnaire survey, interview survey, literature review, expert consultation, etc., and the function and appearance of the intelligent wheelchair were then defined. A brain\u2013machine interface system was developed for controlling the motion of the intelligent wheelchair, catering to the needs of disabled individuals. Furthermore, ergonomics theory was used as a guide to determine the size of the intelligent wheelchair seat, and eventually, a new intelligent wheelchair with the features of climbing stairs, posture adjustment, seat elevation, easy interaction, etc., was developed. This paper provides a reference for the design upgrade of the subsequently developed intelligent wheelchair products.<\/jats:p>","DOI":"10.3390\/s24103000","type":"journal-article","created":{"date-parts":[[2024,5,9]],"date-time":"2024-05-09T05:16:45Z","timestamp":1715231805000},"page":"3000","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":14,"title":["A Brain-Controlled and User-Centered Intelligent Wheelchair: A Feasibility Study"],"prefix":"10.3390","volume":"24","author":[{"given":"Xun","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Mechanical Science and Engineering, Northeast Petroleum University, No. 99 Xuefu Street, Longfeng District, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2569-3290","authenticated-orcid":false,"given":"Jiaxing","family":"Li","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Fluid Power and Mechatronic Systems, School of Mechanical Engineering, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruijie","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Mechanical Science and Engineering, Northeast Petroleum University, No. 99 Xuefu Street, Longfeng District, Daqing 163319, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2797-0264","authenticated-orcid":false,"given":"Tao","family":"Liu","sequence":"additional","affiliation":[{"name":"The State Key Laboratory of Fluid Power and Mechatronic Systems, School of Mechanical Engineering, Zhejiang University, Hangzhou 310058, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,5,9]]},"reference":[{"key":"ref_1","unstructured":"Li, S.
