Hi, I am a design student in a course about Human Factors and Inclusive Design. I am working on a project to redesign self-checkout machines at grocery stores to make them more inclusive for people in wheelchairs and those with mobility issues. I am hoping to learn about the issues people struggle with most when using the machines or why people do not use them. Is the height or distance away from the screen an issue? Would it be helpful if the screen was adjustable or moveable? Are the messages on the screen clear? I would really appreciate any feedback, comments, or suggestions. Thank you for your time!
