Tim
Poston
Activities
Dr
Poston is an interdisciplinary scientist, with over seven hundred mentions
in the Science Citation and Social Science Citation Indices.
He
is co-author of two texts, one on geometry and General Relativity and the
other on Catastrophe Theory, that are still in print more than twenty-five
years after first publication.
He
has published in respected journals and proceedings, from the 5-dimensional
geometry of real binary quartics to vibration spectra of crystals, settlement
patterns in archaeology, rod buckling, vision (human and machine), 3D medical
image analysis, and human-machine interaction.
He
is an author of patent applications for a helical surgical probe (allowing
an indirect and often safer approach to deep brain lesions, with the guidance
algebra to make it usable to the surgeon), for a reach-in interface design,
for rapid means of surface and volume rendering, for a rapid instructional
animation creation system, and others in the area of image-guided drug delivery.
In
collaboration with Intel Corp. he has developed powerful 3D display methods.He
is a pioneer in the development and commercial deployment of desktop hand-immersive
user interaction.
Current Scientific Interests
3D
and 4D geometry as applied to the rapid display (to the senses of sight and
touch) of complex computed objects with
real-time mechanical distortion, biomedical simulation and surgical planning.
Human factors in productive interaction with complex shapes and structures
and with information structures. Access to relevant information in large,
dynamic and disparate collections of data.
