Douglas Engelbart is an American inventor and internet pioneer.
I didn't know that he invented cumputer mouse!
He was looking for efficient pointing devise for interactive display technology.
He had the idea that was to use small wheels traversing the tabletop, one turning horizontally, one turning vertically, each transmitting their rotation coordinates for analysis.
This first mouse had only one button.
I continue writing after I get home!
the first mouse is made of wood which looks very unique for me!
返信削除Mac mouse used to have only one button too, but recently they do have two bottons.
Don't forget to give it a title. Just for fun, when did the second mouse button come around?
