If your only complaint against a touch screen is fingerprints then you don’t need to be that worried. I’ve been looking around and have found more then one way of eliminating them almost entirely. (The most common I found is to coat the screen so that it has the same index of refraction in oil as in air, and as a side bonus it makes the screen have a low index of refraction as a whole.)
basse, no wonder your happy, you have a Wacom. So your already halfway to where I think we should be as a whole.
Here are some reasons I have for and against mice. (this is more conceptual, some of it may not be very practical as we lack the technology to do it… yet. So try not to knock down only the stawmen, but please do point holes and weaknesses out when you see them.)
The small amount of motion is nice because of the laziness factor, but unless you have some medical condition or are really old, the slight bit extra movement of a touch screen wont hurt you in the long run.
Buttons, no where (that I know of) in nature can you find a single “button” that is ether on or off with no in between. Everywhere you look there is going to be a whole scale of pressure sensitivity, I think we should have more of that control when interacting with a computer.
Movement, our brains, and body’s are really good at picking up patterns and using them to our advantage. An example of this is that in order to move the mouse on the screen we have to make a completely abstract movement with our hand on the mouse, but our brains, have learned the pattern of movement well enough that we don’t even have to think about where to move our hand to get that mouse cursor to go where we want it to. I think we could use this “feature” of our brains more effectively then we are with the current mouse design.
I think we have conformed to the limitations of the machines around us so well that I wounder if we even know we are conforming to them anymore. With computers the limit has been raised, but we are still using the old method that was made to conform to the old limit. (qwerty keyboards are an obvious example here.)
Hope that makes what I’m getting at clearer, and I hope there are people on here willing to respond and add to what I’m trying to get at.
