Title      : Designing presentations tools for multiple and high-resolution
             displays
 
Abstract   :
Slide presentations today are ubiquitous. In business meetings, conferences
and classrooms computer generated slides are used as the main visual aids to
support the talk. While current presentation software enable users to create
sophisticated presentations that use multimedia capabilities, animation and
other flashy elements, critics claim that they enforce a rapid, thin,
sequential style of presentation that may not be suited to learning contexts
in which non-linear and complex reasoning is needed. In this talk, I will
first describe an observational study we conducted in order to understand
how to design presentation software that would better support learning. In
the study, we compared presentation practices with electronic slides and
more traditional visual aids such as blackboards and whiteboards in both
classroom and conference settings. I will then describe MultiPresenter, a
presentation system that works on multiple and high resolution displays that
was designed according to the understandings from the observational study.
MultiPresenter provides short- and long-term persistency of information for
the audience. It also supports a wide range of presentation styles, ranging
from automated, scripted style to highly dynamic ad-hoc non-linear
presentations. MultiPresenter was used as the presentation tool in fifteen
classes by six different instructors throughout the semester. Evaluations of
MultiPresenter provide us insight into how large electronic surfaces could
be used for presentation purposes; both instructors and students highly
appreciated the new affordances provided by the tool.
