Title: How to Give a Talk on Computer-Aided Violin Design
Abstract:
I will present some guidelines on giving talks, giving "Do's" as well as "Don'ts". I will illustrate my points by giving two (very!) short versions of a talk on Computer-Aided Violin Design. The points I cover in my talk are discussed in the web page

ABSTRACT

The  last  decade  of  computer technology has seen the
proliferation  of  computer  graphics  applications. As
technology  advances,  there  is  a growing fascination
with three-dimensional (3D) object representations that
likely  comes from their greater ability to match "real
life"  than  their  two-dimensional  (2D) counterparts.
Unfortunately,  the  benefits  of  3D  editing  are not
without  a  price.   Most  techniques  for manipulating
objects   in   a   3D  environment  are  developed  for
conventional  hardware configurations that use 2D input
devices  and  CRT  displays.   The  difficulties lie in
mapping 3D spatial relationships to 2D displays, and in
mapping  2D  user input to 3D object manipulation. This
mapping   problem   is  somewhat  mitigated  by  adding
constraints   to   the   degrees   of  freedom  in  the
manipulation   task.   3D   surfaces   that  have  been
reconstructed from contours are interesting to consider
as  targets  of  3D interaction because they provide an
inherent  constraint  on  manipulation.  In this talk I
present  the results of an experiment that investigates
whether  3D  editing  benefits by constraining the data
points to lie on a set of 2D planes.
