A head array system is an assistive technology that allows individuals to control their power wheelchair using head movements. This system typically consists of a series of sensors or switches strategically placed around the headrest.

When the user moves their head, these sensors detect the motion and translate it into commands that control the wheelchair's movement and functions.

The headrest is equipped with multiple sensors or switches. These sensors can detect various head movements, such as tilting forward, backward, or to the sides. The user is able to move the chair forward by pressing their head against headrest, and move it left and right by tilting their head against the sensors on either side.

The sensitivity of the sensors can be adjusted to match the user's range of motion and strength, ensuring precise control over the wheelchair. The left and right pad can be individually adjusted, allowing for smooth driving for users who have varying levels of head control on their left and right sides.

Some head array systems include auditory or visual feedback to confirm the command execution, enhancing the user experience. Often, this comes in the form of a color display screen, as seen on this Quickie QM-710.

With this display screen, the user is able to adjust the maximum speed of the chair, turn the chair on and off, and cycle through the options menu.

Enhanced Independence: For individuals with limited or no use of their arms and hands, head array systems provide a viable solution for independent mobility. Users can control their wheelchair without the need for hand-operated joysticks or buttons.

Customizable and Adaptable: These systems can be tailored to suit individual needs. The placement of sensors, the sensitivity settings, and the control interface can all be customized to ensure optimal performance for each user.
