This in-lab study evaluated a vision-guided shared control (VGS) system with twelve users completing two multi-step kitchen tasks: a drinking task and a popcorn making task. Using a mixed methods approach participants compared VGS and manual joystick control, providing performance metrics, qualitative insights, and lessons learned. Data collection included demographic questionnaires, the System Usability Scale (SUS), NASA Task Load Index (NASA-TLX), and exit interviews. No significant SUS differences were found between control modes, but NASA-TLX scores revealed VGS control significantly reduced workload during the drinking task and the popcorn task. VGS control reduced operation time and improved task success but was not universally preferred. Six participants preferred VGS, five preferred manual, and one had no preference. In addition, participants expressed interest in robotic arms for daily tasks and described two main operation challenges: distinguishing wrist orientation from rotation modes and managing depth perception. They also shared perspectives on how a personal robotic arm could complement caregiver support in their home.<\/jats:p>","DOI":"10.3390\/s25154768","type":"journal-article","created":{"date-parts":[[2025,8,4]],"date-time":"2025-08-04T16:41:54Z","timestamp":1754325714000},"page":"4768","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Evaluation of a Vision-Guided Shared-Control Robotic Arm System with Power Wheelchair Users"],"prefix":"10.3390","volume":"25","author":[{"given":"Breelyn Kane","family":"Styler","sequence":"first","affiliation":[{"name":"Human Engineering Research Laboratories, VA Pittsburgh Healthcare System, Pittsburgh, PA 15206, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7933-389X","authenticated-orcid":false,"given":"Wei","family":"Deng","sequence":"additional","affiliation":[{"name":"Human Engineering Research Laboratories, VA Pittsburgh Healthcare System, Pittsburgh, PA 15206, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cheng-Shiu","family":"Chung","sequence":"additional","affiliation":[{"name":"Human Engineering Research Laboratories, VA Pittsburgh Healthcare System, Pittsburgh, PA 15206, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Ding","sequence":"additional","affiliation":[{"name":"Human Engineering Research Laboratories, VA Pittsburgh Healthcare System, Pittsburgh, PA 15206, USA"},{"name":"Department of Rehabilitation Science and Technology, University of Pittsburgh, Pittsburgh, PA 15206, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"939","DOI":"10.1080\/09638280500052799","article-title":"Understanding and measuring powered wheelchair mobility and manoeuvrability.
