Eye Tracking


Access your device…with just your eyes.

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

 

PRC’s Look™ eye tracking module is a robust and potentially life-changing solution for children and adults 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.

The large track box provides freedom of movement and operation from a variety of positions, and combined with a very fast gaze recovery can be used seamlessly and continuously.

Look provides the refinement necessary for specific populations. For individuals with progressive neurological diseases, Look has a full range of calibration (0, 5, 7, and 9) and adjustment for speed of cursor movement, stability, dwell selection and timing to create a precise and accurate control required for extensive use for text, communication and control of the Windows environment.

Look has a variety of performance adjustments available for cursor movement, selection and custom interfaces, improving efficiency and ease of use during communicative interactions. Look also works well with eyeglasses and contacts under a variety of lighting environments, and allows for single- and two-eye use.

Small and light, Look offers equal or enhanced performance over other solutions. Look offers industry-leading ease of use and customizations for improving user performance.

Combined with its sleek design, low power consumption and robust performance, Look is an ideal access method for a wide variety of individuals with disabilities requiring the use of eye tracking.

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.

Switches


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
