Imagine being able to use your laptop without needing a keyboard or a mouse --- that's what BT researchers in the UK set out to make possible with BT Balance, an adaptor for laptops and tablet PCs that allows users to access applications, menus and other commands by moving or tilting the laptop. While it takes a leaf out of the gaming world by using Nintendo Wii-style technology, this device is all about everyday use.

Once the adaptor is inserted into the laptop, the user can move the mouse cursor around the screen or scroll through a dcoument by moving or tilting the laptop. How does it work? The adaptor has built-in movement sensors that send signals to the laptop, which then uses software to translate the motions read into actions and commands for the computer.

The BT Balance is designed primarily for computer users who might have difficulties with, or an aversion to, using the conventional mouse and keyboard, such as those who are disabled or elderly. For that matter, it might be handy for anyone who needs to quickly access data on the laptop but doesn't quite have enough elbow room to use the keyboard and mouse at the moment. It's still under development at BT, but is certainly a step in the direction towards making technology accessible to more people.
