Why Touch Is a Stretch for Desktop Computer Interaction

By Deane Barker on January 11, 2013

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.



  1. I agree, in it’s current vertical configuration touch is more or less useless but what if we replaced the mouse/keyboard with a touch equipped device that controlled the screen from a horizontal position? Basically show the screen in two ways, one without a keyboard overlay and one that has one, allowing us to see the keyboard for typing purposes (if necessary) but still allow us to move about the screen with our hands/fingers?
