Presentation Transcript

  1. Dan Cutting • Computer Science at UNSW 1995-1998. • First class honours under supervision of Gernot Heiser. • ‘Protection domains and threads in Mungi’. • Honours thesis. • Mungi is a distributed single address space operating system. • Thesis dealt with making the security and execution abstractions orthogonal. • Travelled and worked in industry. • Backpacked around Europe for a year and a half. • Worked at a few web design companies building web sites and web applications. • Software engineering background using technologies such as J2EE, JSP, C++, etc. • Began PhD in April 2003. • University of Sydney under a UPA and with the SIT CRC. • Aaron Quigley is Supervisor and John Zic is Associate Supervisor. • Interested in Intelligent Environments, specifically management of identity within such context-aware systems.

  2. Stick-es (Jason Pascoe et al., Uni. of Kent at Canterbury) • Mobility of devices is a feature, not a flaw. • Extend UI to user’s environment. The concept of ‘Situated Information Spaces’ is to attach metadata to physical objects. • Can generalise the metaphor to tagging various contexts with metadata. • Contextual information includes location, time, etc. plus higher level inferred information. • Gloss/Hearsay (Alan Dearle et al., Uni. of St. Andrews) • Region Transition Hypothesis. • Allows construction of tree hierarchy of contextual servers/nodes. • Hearsay similar in utility to Stick-e project. • Gloss concentrates more on scalable infrastructure than matching of contextual situations. • WISE/UBIWISE (John Barton et al., Stanford/HP) • Simulator for ubiquitous computing environments. • WISE focuses on mobile/wireless device interfaces. • UBIWISE extends WISE with a 3D environment. • Berkeley Motes • Small, self-organising, wireless sensors (Mote/Mica/Dust/Spec) running TinyOS. • Latest devices measure 2mm x 2.5mm.

  3. MagicBook (Mark Billinghurst et al., HIT Lab NZ) • Augment physical environment with virtual objects. • Uses fiducial markers printed into a physical book, and a headset to view virtual objects. • Not directly relevant to intelligent environments, but could be used to augment or improve user perception of such spaces. E.g. Would work well with Stick-es. • Identity management • Certainty of identity impossible (Roger Clarke, ANU). • Should be considered when designing systems relying on notion of identity. • But often considered an axiom (e.g. DNA testing). • Use concept of ‘evidence of identity’ not ‘proof of identity’. • Same concept can be applied to context-awareness. • Schedule • CRC Student Workshop (June 5-6). • Submission to UbiComp Doctoral Colloquium (July 11). • UbiComp conference in Seattle (October 12-15). • Proposal for thesis (November-December).
