Has anybody shown that they are sensible form of panning technique?
I'm glad Sun haven't gone for them straight off, as it may encourage
toolkit implementors to look at alternative forms of panning before
settling myopically for scroll bars.

Common alternatives are dragging a point in the picture to the
clipping window edge (as in MacPaint - love it) or moving the cursor
just over the edge of the clipping window (works on some Mac
Applications). There is a comprehensive survey of interaction
techniques in:

%A J.D. Foley
%A V.L. Wallace
%A P. Chan
%T The human factors of computer graphics interaction techniques
%J IEEE Computer Graphics and Applications
%V 4(11)
%P 13-48
%D 1984

Smart CAD/CAM implementors may also have done something that the GWU
crowd don't know about, so you could extend your repetoire by having a play
at the next CAD/CAM exhibition near you.

Oh - and be sure to see a psychologist before you hard-code anything :-)
If you don't get on, at least get some ideas from:

%A W. Buxton
%T There's More to Interaction Than Meets the Eye: Some Issues in Manual Input
%B User Centred System Design
%E D.A. Norman
%E S. Draper
%I Laurence Erlbaum
%P 319-337
%D 1986

Bill Buxton has some nice ideas about gesture input which are more digestible
than raw Human Factors papers (unless you're a Human Factors
specialist, in which case they digest easily but make you wish you'd
eaten somewhere a bit more adventurous and cosmopolitan :-))
