“…The proposed GUI incorporates both a manual mode and a self-driving mode. The manual interface is based on our previous study [58] [59], features an on-screen joystick suitable for patients with cervical spinal cord injury. The wheelchair can be operated manually by the operator dragging this on-screen joystick.…”

Electric wheelchair-mounted robotic arms can help patients with disabilities to perform their activities in daily living (ADL). Joysticks or keypads are commonly used as the operating interface of Wheelchair-mounted robotic arms. Under different scenarios, some patients with upper limb disabilities such as finger contracture cannot operate such interfaces smoothly. Recently, manual interfaces for different symptoms to operate the wheelchair-mounted robotic arms are being developed. However, the stop the wheelchairs in an appropriate position for the robotic arm grasping task is still not easy. To reduce the individual’s burden in operating wheelchair in narrow spaces and to ensure that the chair always stops within the working range of a robotic arm, we propose here an operating system for an electric wheelchair that can automatically drive itself to within the working range of a robotic arm by capturing the position of an AR marker via a chair-mounted camera. Meanwhile, the system includes an error correction model to correct the wheelchair’s moving error. Finally, we demonstrate the effectiveness of the proposed system by running the wheelchair and simulating the robotic arm through several courses.

Approximately half of the patients with spinal cord injuries in Japan have a cervical spinal cord injury. Owing to the trunk dysfunction, patients with high-level spinal cord injuries have particular difficulty when searching for or picking up objects from the floor. Recently, welfare robot arms have been developed to help such individuals increase self-reliance. In this study, we propose an operating system that includes an eye-in-hand system with a touchscreen interface for grasping objects from the floor and delivering them to the individual. In the proposed method, the visual information of the target object is shown on a touchscreen interface. The patient specifies the target position for the robot arm by drawing a line on the target object on the interface. We conducted an experiment to compare the proposed interface with an on-screen joystick to demonstrate the proposed system’s efficiency and its ability to reduce physical burden. The results show that the proposed method is both quicker to use and effectively reduces the physical burden on the user compared to the conventional method.
