[IxDA Discuss] "Interface-Free" Interface

[Miguel Gonzalez]

A Stylus? No, it won't solve the problem.

Let me say something else about touch screens, it's not only the interface design, the software
running on it, but the ergonomic of the touch screen.

Right now, while you are reading this post, you may be sat in front of your screen and the
keyboard and mouse in between close to you, now do this test for some minutes...

Take away your keyboard and mouse and place the monitor in a suitable distance for you and start
touching the screen, or using an stylus, as it would be a real touch screen, after a few seconds
you will feel your arm muscles hitting up about your shoulder, after a couple of minutes, that
feeling will become discomfort, one more minute it will be pain. Our arm's muscles are not ready
for that position.

This could be solved by modifying the environment around the computer, your desk, placing the
touch screen in a position where you don't need to have your arm extended, placing the touch
screen in a position where your arms could be relaxed.

As you see, those are too many things to change to take one thing working, the market won't make
such a big change just to accommodate a new technology that is not better than what already exist.

Different is with one of those tablet computers but then we are talking of a different thing, I am
talking of a touch screen systems as a substitute for desktop computers.
