Hi All
There have been quite a few discussions about the merits, or not, of touch screens, and thought that instead of adding it to other posts, a new thread would be in order.
Anyway here’s something to think about.
The human being works a lot more efficiently if they can press what they see, rather then having to look, to see which button they need to press, to achieve what they can see onscreen.
The touch screen is used in all types of jobs and walks of life, and because there are no moving parts, there is nothing to wear out or clog up; in fact for a lot of jobs and uses the touch screen is the best input device that was ever invented. (Thought control is still some way off)
There is however one thing about a touch screen that some keyboard manufactures have not yet realised, and which was identified in other industries a long time ago, and that is, that a screen that is too small, badly laid out or the use of the wrong colours, wreaks total havoc for the person that has to use it.
When keyboard manufactures get this sorted, (Some already have) then the touch screen will realise its full potential in keyboards.
A good touch screen BTW should allow you to just lower your eyes (Without moving your head) and not have to refocus to see it, and to also have large and well defined buttons, with similar functions grouped together.
Another viewpoint on the touch screen to consider.
