The scroll wheel becomes indispensable in many applications, and the four buttons can be programmed to perform different app-specific functions. It’s a solid, well built and responsive input device. Using the setup utility to put it into pen mode rather than mouse mode, and adjust the height sensitivity and speed of the pen, means I can quickly move around the three 24-inch screens I have in my setup.įor the trackball, I have a Kensington Expert Pro. The tablet doesn’t need to be large or over specced I currently use a medium Wacom One, which is 18.9cm x 27.7 cm, with an active area of 21.6 x 13.5 cm. The key to the prevention of pain and injury, I have found, lies in dealing with the ‘R’ of ‘RSI’ - the repetition, so now I have settled on using both a tablet and a trackball, regularly swapping between them. I switched to a trackball, and then some time later developed pains across my hand, so switched back to the pen and tablet. Predictably, sometime later I started to notice pain in my shoulder whenever using the tablet - caused by the minor but repetitive pressure applied whenever pressing the pen down. Also, I found myself working a lot quicker, being able to move around the real estate of the screen so much faster - and using the pencil tool to draw out unwanted clicks became a breeze. The hand, being in a more vertical position, felt more recognisable and natural, with less ‘gripping’ to add prolonged stress to all the muscles and tendons in the active limb. Initially, it felt a little strange and unwieldy, but by swapping back to the mouse every so often after a couple of days I found myself using the tablet all the time. Nothing felt comfortable or efficient until I borrowed a Wacom pen and tablet.
