  In order to reduce the burden on caregivers, we developed an intelligent
electric wheelchair. We held workshops with caregivers, asked then regarding
the problems in caregiving, and developed problem-solving methods. In the
workshop, caregivers' physical fitness and psychology of the older adults were
found to be problems and a solution was proposed. We implemented a cooperative
operation function for multiple electric wheelchairs based on the workshop and
demonstrated it at a nursing home. By listening to older adults, we obtained
feedback on the automatic driving electric wheelchair. From the results of this
study, we discovered the issues and solutions to be applied to the intelligent
electric wheelchair.
