Abstract
Electric power wheelchairs (EPWs) enhance the mobility capability of the elderly and the disabled, while the human-machine interaction (HMI) determines how well the human intention will be precisely delivered and how human-machine system cooperation will be efficiently conducted. A bibliometric quantitative analysis of 1154 publications related to this research field, published between 1998 and 2020, was conducted. We identified the development status, contributors, hot topics, and potential future research directions of this field. We believe that the combination of intelligence and humanization of an EPW HMI system based on human-machine collaboration is an emerging trend in EPW HMI methodology research. Particular attention should be paid to evaluating the applicability and benefits of the EPW HMI methodology for the users, as well as how much it contributes to society. This study offers researchers a comprehensive understanding of EPW HMI studies in the past 22 years and latest trends from the evolutionary footprints and forward-thinking insights regarding future research.

Summary
Academic Editors: Joost van Hoof and Paul B. Publisher’s Note: MDPI stays neutral with regard to jurisdictional claims in published maps and institutional affiliations. According to the World Health Organization (WHO), globally, 75 million people needed a wheelchair by 2018 [1]. Due to the aging population and the growth of noncommunicable diseases, the need for wheelchairs is increasing. The electric power wheelchair (EPW), as an assistive device for mobility, may enhance the mobility capability and experience of the elderly or the disabled. The EPW human-machine interaction (HMI) methodology, referring to the two-way information exchange of various symbols and actions between the user and the EPW system, plays a key role in EPW design
