- Excuse me if my observations are old stuff--I just dropped in on comp.
- human-factors this evening. The experiences quoted were very
- interesting. I would like to propose, however, that trackballs and mice
- serve different purposes, and different people need different pointing
- devices:
-
- profession typing skill pointing device
- ---------- ------------ ---------------
- Secretaries Touch Neither
- Writers Handicaped Trackball
- Two-fingered Mouse
- Touch Both
-
- Secretaries format as they type, according to the instructions on
- their paper "copy". For them formatting with control and escape keys
- is best, for they needn't remove their eyes from the paper; and
- pointing devices of any kind are of questionable value.
-
- Writers view the screen as they type. My writing is separated into
- three stages: composing with minor editing, major editing and revising,
- and formatting. I'm a touch typist. When composing, I don't look at the
- keyboard; the minor edits needed I perform by pressing the first letters
- on menu selections, but I could easily use a trackball permanently mounted
- on the keyboard. During major editing I need a pointing device, but one
- whose position I know as well as a key's. Formatting, previewing, and
- reformaltting is a totally different activity which I prefer to do moved
- away from the desk, with my legs crossed comfortably--a cola in one hand
- and a mouse in the other.
-
- Those who look at the keyboard aren't distracted by having to find a
- mouse, though handicaped typists with limited movement find trackballs
- better or necessary.
-
- The above are just my un-read opinions. (Fact is, at home I don't use
- a word processor. I compose and edit with a program editor, then add
- ASCII formatting codes when I'm done. A post-processor formats for me.)
