The first thing to consider with communication aids is their weight and size. They can range from very light aids to large heavy dedicated devices.
Consider the following devices:
- Tobii Dynavox I-15+ which weighs 4 Kg
- Smartbox Grid Pad Eye 11 which weighs 1.7 Kg
- iPad Air which weighs 456 g.
Each of these devices will have different requirements:
- The Tobii Dynavox at 4 Kg will require a stronger mounting arm to support its weight.
- The lighter Smartbox Grid Pad Eye at 1.7 Kg could use a lighter solution.
- The iPad Air at 456 g can be securely mounted with even smaller, lighter solutions.
Older, heavier devices can be 7 or 8 Kg in weight.
Consider the following when choosing a solution:
- Mounting a communictaion aid may have implications for safety and so use the Mounting Assistive Technology Documentation (MAT-DOC) Best Practice Guidelines.
- If the device is heavy, will it effect the stability of the wheelchair?
- How will a wheelchair cope with inclines/slopes with the mounting arm and device attached?
- Can the user see past the device when attached?
- Will the device need a quick release mechanism?
- Is the wheelchair frame (or the edge of a desk) strong enough to support a heavy mounting and device?
