Whilst many computer users take the mouse for granted, anyone who suffers with hand tremors finds it an extremely difficult device to use. Precise movements and static double-clicking are actions that anyone with unsteady hands and fingers can find well-nigh impossible, thus restricting them from the full potential of PCs.
To meet this need, IBM have developed an adapter that sits between a conventional PS2 mouse and the PC. Based on the ‘steadycam’ technology commonly used in video cameras to stabilise a picture, shaky hand movements are filtered out. The sensitivity of the adapter can be adjusted to the needs of the user.
A USB version of the device is under development, which should mean that it will be compatible with newer Apple Mac modelsâ€”which have never used the PS2 hardware formatâ€”as well as being hot-pluggable. The system does not work well with laptop PCs as it interferes with their built-in tracking hardware.
The Assistive Mouse Adapter retails at UKÂ£65 ($99.00 US/Canada/Rest of the world).
