Abstract - The smart wheelchair is need of disabled person for transportation and a replacement for walking especially in indoor and outdoor environment. Wheelchairs and stretchers are the most essential part of the hospital for transportation of patients. Transferring the patients from wheelchair to stretcher or to the medical bed is always an issue for the patients as well as for the attendants/ nurses. This may even result in musculoskeletal disorders to those who are not trained to do so especially, when it comes to the caretakers. So there is a need of automatic gesture control wheelchair with stretcher to facilitate the disabled patient’s mobility and to provide novel medical equipment for use in the hospitals. The caregiver can merely shift the patient from a bed on to the device while the device is in the form of a stretcher, otherwise in absence of caregiver patient can operate wheelchair by itself. The device can be convert wheelchair into stretcher automatically with a press of a button. This can be done in the reverse direction as well as, when the patients in sitting in the wheel chair can be converted to a stretcher smoothly for the purpose of diagnosis etc. Wheelchairs are used by the people who cannot walk due to physical illness, injury or any disability. The present article presents a gesture based wheelchair with stretcher which controls the wheelchair using hand movements. The system is divided into two main units: MEMS Sensor and wheelchair control. The MEMS sensor, which is connected to hand, is a 3axis accelerometer with digital output that provides hand gesture detection. The wheelchair control unit is a wireless unit that is developed using other controller. Key Words: Mobility Aid, Stretcher, Wheelchair control, Hand gesture recognition, Wireless. Automatic wheelchair is a device which can gives the independent mobility to the paralyzed person. Automatic wheelchair can control by the hand gesture. The most of wheelchair can operate buttons, joysticks to control the motion wheelchair. The system enables the patient to have command over the wheelchair its direction of movement and conversion of wheelchair into stretcher. This wheelchair helps the user to move in environments without help of other persons. This work is based on previous research in wheelchairs must be highly interactive to enable the system |
2. NEED OF PROJECT The movement of wheelchair is possible in four direction, that will tried to achieve backward, forward, left, stop and right motion which gives the independent mobility to paralyze person.

to work most efficiently. To avoid the problem associate with wheelchair having joysticks, the alternative to joystick control various motions of human body such as head movement, hand gesture, voice controller, chin controller Electromyogram (EMG), or Electrocephalogram (EEG) signal controller are developed to improve comfortless and easy to operate the wheelchair to the patient. The hand gesture recognizes the detecting, tracking and directing which is works as human robot interface for the intelligent wheelchair. It is demonstrate that the accelerometer is to transmit the effective signals. The accelerometer is device which measure magnitude and direction of gravity to movement induced acceleration. The accelerometer sensor can works in three axes with respect to gravity, by using a single chip wireless solution with a MEMS (Micro Electro-mechanical system) accelerometer. The gesture controlled wheelchair is suitable to physically challenged people. For hand gesture controller consist (Micro Electro-mechanical system) MEMS accelerometer sensor which highly sensitive and able to sense the tilt. By using accelerometer sensor the motion wheelchair can change by the tilting the figure. Due to accelerometer sensor wheelchair movement possible in left, right, forward, backward and stop direction. It can easy to operate by the patient. Hence the physically chandelled person can control their wheelchair with their hand gesture. [3]

Study helps to identify the need of the product, product environment and users experience. From literature survey wheelchair with stretcher is basic need in hospital. The many of people due to accident, unspecified birth issue, post- polio syndrome, spinal cord injury and many other problems causes a paralysis. The paralyze person suffering from independent mobility, they require need help of other person to travel from one place to another .Due to lack of force paralyze person can’t manipulate wheelchair with their arm. So to overcome this problem, the gesture controller wheelchair comes. The gesture controller wheelchair can ISO 9001:2008 Certified Journal
