How to Use a Computer If You're Paralyzed
- 1). Setting up a device that interprets brain signals is one the best ways to allow paralyzed PC users quick and easy access to their computer. These methods are still new, and many advances are being made to streamline the functionality of these devices. Several devices are on the market currently that monitor a user's brainwaves and interpret them into input commands for the PC. Electrodes that are worn on the head monitor the user's beta brainwaves, and the user can calibrate these systems to interpret the impulses into usable commands. These devices work differently for each user and are highly customizable. One user may be able to set up these types of devices to work with certain thoughts, and other users may calibrate the device to work with muscle commands. In either circumstance, after calibrating the device, computer use will become much easier.
- 2). Implementing head motion tracking software can help users that have some level of control of their neck muscles. Tracking equipment is attached to the computer that monitors the location of the user's head and interprets motions into input commands. Sensor arrays use infrared cameras to locate and track the position of the user's head and eyes. Using the software that controls the sensor, commands are calibrated to be associated with certain movements and positions. These commands have a broad range and are used to control everything from keyboard commands to mouse movements and clicks. Eye movements can also be interpreted to a large extent and used for a large range of commands, which makes this option valid for individuals who do not have a wide range of head movement.
- 3). Purchase a light-operated mouse and keyboard. Light-operated mouse and keyboard setups are used to track input commands from a user via a laser pointer that is attached to his head. The device works by using a control panel that is made up of more than 100 photosensitive keys that are activated when the laser is aimed at them. These keyboard and mouse setups are effective and allow users that have a range of head motion to navigate their computers and type messages effectively.
