Talk:Light pen
From Wikipedia, the free encyclopedia
A light pen is not the same thing as a laser pointer. -- Zoe
It was a blank entry anyway - I didn't remove or move any text. write it or delete it if I was wrong. I'm trying to clear up some of the stubs - ATM there are fifty entries with a zero character list so any that can be made redirects or removed should be. ~KJ
[edit] Date of first use
The first light pen was used around 1957 on the Lincoln TX-0 computer at the MIT Lincoln Laboratory. it was first reported to the public in 1969 by Ivan Sutherland.
When merging Lightpen and light pen, one had: The first light pen was used around 1957 on the Lincoln TX-0 computer at the MIT Lincoln Laboratory. the other had: it was first used in 1969 by Ivan Sutherland.
Which one is correct. I think:
- Lincoln TX-? (0, 1, or 2)
- Ivan Sutherland
- MIT Lincoln Laboratory
are correct, but i cant find which one it should be, or the date tooto 16:36, 6 Aug 2004 (UTC)
Ivan Sutherland made many contributions to computer graphics but the light pen is not one of them, nor did he "first report it to the public." It was used in the SAGE air defense system (developed by Lincoln Lab) in the 1950's. The IBM 2250 announced in 1964 came with a light pen and that feature was not considered innovative at the time. Also see the article on light gun.

[edit] what is this lightpen
[edit] "guns" on arcade machines
Would I be correct in thinking that the guns used in certain arcade machines (the sort where you stand and literally shoot at the screen) work on the same principle?
If so, perhaps the article could mention this.
You would be mostly correct, however there is already a link to Light Guns in the article in the See Also section. -Branin
