From: Henry Lieberman <Henry%MIT-OZ@MIT-MC.ARPA> I kid you not. I recently had a demo of CMU's son-of-Zog system on the Perq. One thing that was impressive about it was the mouse interaction. They had adjusted their mouse software so that the distance the cursor moved in response to a unit distance movement of the mouse varied with the speed of the mouse movement. If you tried to move the mouse rapidly, it moved faster, good for getting the mouse across large screen distances quickly. If you moved it slowly, it moved more slowly, good for fine positioning. They used five different speeds. It made the mouse feel a lot more responsive. How 'bout the same thing for the Lisp machines, folks?

I recently had a demo of CMU's son-of-Zog system on the
Perq. One thing that was impressive about it was the mouse interaction.
They had adjusted their mouse software so that the distance the
cursor moved in response to a unit distance movement of the mouse
varied with the speed of the mouse movement. If you tried to move the mouse
rapidly, it moved faster, good for getting the mouse across large screen distances
quickly. If you moved it slowly, it moved more slowly, good for fine positioning.

This has existed on the CADR (LM-2) for many years. Not on the 3600 yet,
unfortunately. Probably it never got documented. Example code that uses it
(found in my init file):
(DEFUN HAWLEY-MOUSE-HACK ()
(MOUSE-SPEED-HACK 1 120 2))
;Aids to trying speed-dependent scaling
;Specs are scale-factor speed-break
;No attempt to treat X and Y differently
;Args of (1 120 2) seem to be about right for the Hawley mouse (10-second experiment)
(DEFUN MOUSE-SPEED-HACK (&REST SPECS)
(LOOP FOR (SCALE SPEED) ON SPECS BY 'CDDR
FOR I FROM 0 BY 2
DO (ASET (OR SPEED 37777777) TV:MOUSE-X-SCALE-ARRAY I)
(ASET (OR SPEED 37777777) TV:MOUSE-Y-SCALE-ARRAY I)
(ASET (// (FIX (* 2 SCALE 1024.)) 3) TV:MOUSE-X-SCALE-ARRAY (1+ I))
(ASET (// (FIX (* 3 SCALE 1024.)) 5) TV:MOUSE-Y-SCALE-ARRAY (1+ I))))rom%SCRC-VIXEN@sri-unix.UUCP (11/02/83)
