PDA-based Visualization Control and Annotation Interface

Virtual Reality (VR) system can be a useful tool to
support visualization tasks. However, the current available
input devices for VR limit the control and navigation within
the Virtual Environment (VE). To overcome this problem,
we designed a user interface by using Personal Digital Assistants
(PDA) for scientific visualization purposes. Through
this system, it is possible to change visualization parameters,
put marks, or write a memorandum within the VE. We
can use the VE for recording memoranda by using the PDA
as a writing utensil or by drawing on the PDA touch screen
for after-placement into the VE. The main advantage of this
method is that it supports the use of any language, because
the characters are drawn avoiding the necessity of typing.
We evaluated both kind of drawing tasks and verified that
the first method is suitable for drawing figures and the second
one is useful for drawing characters within a VE.
