The Grid 2 has been designed to be accessed by everyone, from those with complex disabilities to people with good motor control.
Switches are one of the most common alternatives to a keyboard and mouse for people with disabilities. Switches come in many shapes and sizes, and can be used almost anywhere there is a reliable, reproducible physical movement.
The Grid 2 supports the use of up to 8 switches, although most people use just one or two.
Making selections using switches involves a process called scanning, in which cells are highlighted in turn. The Grid 2 has many options for scanning to allow all users to get the most efficient and least frustrating setup. Some of the switch features include:
- Simple or row-column scanning
- Automatic, tap-to-advance or hold-to-advance scans
- Adjustable switch timing
- Hold a switch for a long time for a different action
- Use additional switches for extra functions
- Filtering of accidental switch presses
- Switch settings preview (for testing settings as you change them)
Touch screens are a very common way to access a communication aid. A touch screen provides direct access to the options on the screen.
Using a touch screen in The Grid 2 is straightforward. The following options are available:
- Ignore accidental presses
- Select "on touch", "on release" or by holding down your finger
- Magnified cells
- Fix grid layouts so that a keyguard can be used
Head pointers such as the SmartNAV detect head movement. The Grid 2 allows you to make selection with a switch or by resting on a cell, and supports use with other programs via Computer Control.
The Grid 2 has comprehensive support for several major eye gaze systems: MyTobii, Alea Intelligaze, LC eyegaze and EyeTech Quick Glance (other systems can be used via the mouse control options). The eye gaze features include:
- Select with dwell, blink or external switch
- User-adjustable selection time
- Selection of ways to show highlight and dwell selection, including option to show/hide the gaze point
- Eye monitor to provide feedback from camera
- Rest function to provide a break from eye gaze
Keyboard and mouse
You can also access The Grid 2 with a standard or modified keyboard and mouse. The speech and word finding features in The Grid 2 allow quick and effective voice output communication, whilst the simplified email and sms grids can allow people who are not proficient with computers to access these methods of communication.
