Why Touch Screens Will Not Take Over: I gotta say, I agree with this guy. Everyone says touch will come to all computers, even the ones that you sit in front of at your desk. But I just don’t see it.
I’ll tell you why not: because of “gorilla arm.”
There are three big differences between these handy touch screens and a PC’s screen: angle, distance and time interval.
The screen of a phone or tablet is generally more or less horizontal. The screen of a desktop (or a laptop on a desk), however, is more or less vertical.
Yes, a mouse is old school. But it’s also damn comfortable. I can’t imagine reaching up to my monitor all day long. Throw in a brutal morning workout at the gym, and I’m really not going to be in the mood.
Bottom line, computers need to support both interaction models. At least for the foreseeable future.
