Abstract—The term mobility aid used in this study refers to wheelchairs for disabled people. This product was designed with RFID technology to send and receive signals through processors. The protective device utilizes sound alarm and warning lights and is combined with fan-shaped or fence-type shutter gates as shields. The RFID device can be fixed to the wheelchair or temporarily attached to the permit, so that when the disabled person gets close to staircases or danger zones, the protective device installed would send off alarms and lights as a warning. If he continues to move toward that area and gets inside the default range of danger, the shield guard is activated to prevent the person from falling down the staircase or stumbling into the danger zone, thus ensuring his safety.
