Why We Won't Be Switching to Touchscreen PCs Anytime Soon
TechCrunch's Michael Arrington found himself wondering why even he ends up reverting to the mouse and keyboard when using a touchscreen device like HP's TouchSmart. The simple answer is that they're just not comfortable. When sitting at a desk, constantly raising your arms to touch a screen quickly brings discomfort. Experts told Arrington this has to do with the cardiovascular strain of lifting your hands above your heart. This is also why these devices tend to work well in a kitchen, where you're standing at a counter and above the level of the screen. For the same reason, the Microsoft Surface table-top computer is relatively comfortable for users.
Arrington suggests the solution is to, simply enough, angle the screen. His inspiration? The architect's desk -- a slightly angled desk that's set at a height lower than those of most computer stations. If HP were to angle such a computer at roughly 25 degrees, with the bottom of the screen almost at lap height, Arrington thinks consumers would love it and could toss their keyboards and mice (mouses?) in good conscience.
Of course, those of us who have tried to peck out more than just a few short sentences on a touchscreen keyboard know that, while touch might replace a mouse, those physical QWERTY keys won't be getting the heave-ho anytime soon. [From: TechCrunch]
