DESCRIPTION:I'll be practicing two 15 min presentations that I'll be givin
 g at TABLETOP 2007 next week.\n\nAbstract for "T3: Rapid Prototyping of Hi
 gh-Resolution\nand Mixed-Presence Tabletop Applications":\nMulti-person ta
 bletop applications that require a high display resolution\, such as colla
 borative web-browsing\, are currently very difficult to create. Tabletop s
 ystems that support mixed-presence collaboration\, where some collaborator
 s are remote\, are also hard to build. As a consequence\, investigation of
  some important tabletop applications has been rather limited. In this pap
 er\, we present T3\, a software toolkit that addresses these challenges. T
 3 allows researchers to rapidly create high-resolution multi-person tablet
 op applications for co-located or remote collaborators. It uses multiple p
 rojectors to create a single seamless high-resolution tabletop display\, a
 nd allows multiple tabletops to be connected together to support mixed-pre
 sence collaboration. This engineering is hidden behind a simple\, flexible
  API. T3 also supports existing user interface components\, including butt
 ons and spreadsheets\, allowing the rapid creation of complex tabletop app
 lications.\n\nAbstract for "Distributed Tabletops: Supporting Remote and M
 ixed-Presence Tabletop Collaboration":\nMixed-presence tabletop interfaces
  aim to support collaboration between remote groups. However\, it is uncle
 ar why tabletop interaction techniques should be important for mixed-prese
 nce or remote collaboration\, and recent projects in this area differ as t
 o which elements of tabletop interaction they choose to support. In this p
 aper we discuss the benefits of tabletop interaction for mixed-presence an
 d remote collaboration. In particular\, we wish to support the natural tab
 letop awareness mechanisms of territoriality\, orientation and consequenti
 al communication. We derive design guidelines for such systems and present
  Distributed Tabletops\, a novel system that can be customised to investig
 ate various mixed-presence tasks. Our early observations of Distributed Ta
 bletops in use validate our design guidelines.\n\n
