Eye Gaze & Access Technologies

At PRC, we recognize that everyone is unique. Solutions for one person may not be right for another. It's why we offer a wide variety of AAC device access options: to maximize an individual's ability to communicate. Our Consultants work with your speech-language pathologist (SLP) to create the right solution for you, your child or an adult using AAC.

Eye Gaze

Access your device…with just your eyes.

PRC's NuEye eye gaze system allows children and adults to control their AAC communication device using only their eyes


PRC’s NuEye® Tracking System is a robust solution for children and adults who need hands-free and switch-free device access. Built in conjunction with SMI, a world leader in eye-tracking technology, this powerful system offers highly precise selection, permitting individuals full control of their PRC device.

This is potentially life-changing for individuals with severe physical disabilities who are unable to control a computer through more conventional means, such as a mouse or keyboard, or are unable to utilize other methods which require access through touch – for example, via a switch or touchscreen.

NuEye is highly accurate, precise and easy to use. With NuEye, individuals with limited or declining physical abilities, such as those with ALS, can use their eyes to communicate and interact with others.

Small, portable and lightweight, the system attaches quickly and easily to the Accent® 1400 or Accent 1000.

Calibration takes no time at all, and individuals can be up and running in minutes. Images, words or letters are "selected" by gazing for a specified period of time to generate speech.

Extremely versatile, NuEye comes with a large track box area to accommodate a wide range of head movement. NuEye also works with eyeglasses and contact lenses. Highly tolerant to sunlight, NuEye can be used indoors or out.

Ideal for all ages, NuEye is an effective solution for ALS patients, Cerebral Palsy, Rett Syndrome and more.

Head Pointing

For those who have limited or no use of their hands, there’s NuPoint®.


NuPoint Attachment


NuPoint uses optical sensors to track the device user’s head movements to make on-screen selections. A small, reflective dot is placed on the individual's forehead, glasses or other convenient spot, converting the natural movement of the head to accurately control the pointer on the screen.

NuPoint calculates how light reflects off the dot to detect the head's movement, with the on-screen cursor moving in the same direction as the individual's head movements. Key activations are made by dwelling over the desired key.

Additional movement settings, like vertical and horizontal controls help customize control of the pointer to optimize accuracy and ease of use.

When eye gaze and head pointing aren’t possible, switches provide an option for AAC device access.

Switch Example


Switches can be activated using:

  • Hand
  • Knee
  • Elbow
  • Foot
  • Other body part

Switch scanning allows the person using the AAC device to select the desired word, letter or symbol as it’s being highlighted by the device.

Switches are entirely flexible, with 1-switch and 2-switch scanning available.

With 1-switch scanning, the individual activates the switch when the desired key is highlighted. With 2-switch scanning, two switches are used: One to move the scan while the other switch selects the key.

Switches can also be paired with other access methods such as head pointing or joysticks for maximum efficiency and ease of use.

Switches are also available in either wired or wireless configurations and can be used to control other types of devices including toys or environmental controls.

Joystick & Alternative Mouse Control

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:

  • How long it takes your device to register a selected location
  • How sensitive the movement of the cursor is to the movement of the joystick/mouse (both vertically and horizontally)
  • Whether a switch should be used in conjunction with the mouse/joystick
  • The appearance of the keys
