AAC devices offer a variety of alternate access methods including eye tracking, head tracking, AAC switches and joysticks so individuals with physical limitations can operate his or her device. Return to Overview
Users can work with their AAC device using a variety of access methods:
Multiple selection methods can enable children with even severe physical limitations to use and communicate with their AAC device.
Almost something out of science fiction, eye gaze is ideal for children and adults who needs hands-free and switch-free device access.
It works by continually tracking the movement of the user’s iris – the center part of the eye – to give users full control of the device. Keys are “selected” by gazing for a specified period of time to generate speech.
Precise and accurate, eye gaze systems can be calibrated as needed for both children and adults, and works with most eyeglasses and contact lenses.
Easy to use and simple to set up, PRC's Look™ Eye Tracking System is the only system available where most users can make developer-grade adjustments themselves for maximum control and effectiveness.
PRC's NuPoint® headpointing module is an effective access solution for those who have limited or no use of their hands.
Using optical sensors, NuPoint tracks a small reflective dot on the user’s forehead, glasses or other convenient spot, allowing the user to control the device. Key activations are made by dwelling over the desired key. Additional movement settings, like vertical and horizontal controls, help customize control of the cursor to optimize the user’s accuracy and ease of use.
When direct (touch) access isn’t possible, some users may opt to use a standard USB mouse or joystick.
Most standard USB mouse and joysticks work with PRC Accent® devices, though some extra equipment (available from PRC) may be required.
In addition, products such as the BJOY ring, available from PRC in either a wired and wireless option, has the added advantage of eliminating the need for multiple controllers.
Settings for an external mouse or joystick can be customized within the Accent software, according to an individual's need. Specific adjustments include:
PRC devices are compatible with a wide variety of switches that can be activated by a hand, knee, elbow, foot or other body part to control a device.
Switch scanning allows the user to select the message by activating a switch at the moment the desired word, letter or symbol is highlighted.
Switches can be wired or wireless and adjusted independently to accommodate a broad spectrum of physical abilities.
We offer a wide variety of switches that can accommodate a range of motor abilities.
