A new control system of a hand gesture-controlled wheelchair (EWC) is proposed. This smart control device is suitable for a large\nnumber of patients who cannot manipulate a standard joystick wheelchair. The movement control system uses a camera fixed on\nthe wheelchair. The patientââ?¬â?¢s hand movements are recognized using a visual recognition algorithm and artificial intelligence\nsoftware; the derived corresponding signals are thus used to control the EWC in real time. One of the main features of this\ncontrol technique is that it allows the patient to drive the wheelchair with a variable speed similar to that of a standard joystick.\nThe designed device ââ?¬Å?hand gesture-controlled wheelchairââ?¬Â is performed at low cost and has been tested on real patients and\nexhibits good results. Before testing the proposed control device, we have created a three-dimensional environment simulator to\ntest its performances with extreme security. These tests were performed on real patients with diverse hand pathologies in\nMohamed Kassab National Institute of Orthopedics, Physical and Functional Rehabilitation Hospital of Tunis, and the validity\nof this intelligent control system had been proved.
