• Ubiquitous, Multiple-Device Access• Hint-Based Coaxing- user is “coaxed” to change Personal Presence Info when: logging on from the PC
at a location different than the “current” location connecting from the Mobile PDA and a different location is “current” starts typing on a PC (with liveupate-pc) and another location is “current”

Live addressbook:A small-scale trial
Three Workgroups:
• Group E -remotely located with much moving
-“high-tech” developers, designers collaborating on a single system
weekly, scheduled teleconferences
-heavy use of email and Instant Messaging
•Group P-co-located with frequent travel
-range of job functions and technology abilities.
-heavy use of telephone & email, not IM
Had Palm/Pocketnet PDA equipment
•Group M-remotely located, but less collaboration
- manager/employee relationship

Design Insights•How Much Information ?(Informativeness vs Privacy)
Personal Location and Availability Information are both useful for telephone communication.
• Telephone “buddy lists” can peacefully co-exist with standard personal phonebooks
•How to keep Information Up-to-date ? (Overhead vs Control)
Users will attempt to keep Personal Presence Information current, especially if the overhead is low.
Support for communication and Presence updates through multiple access methods is useful.
Mixing auto-detection and manual updating is a useful (and low-risk) overhead reduction strategy.
Personal Availability Information is much more difficult to keep current than Location.

Design Insights
• How to Convey the Information ? (Publish/Subscribe vs Situated Negotiation)
Publish/Subscribe works well for Location Information
Situated negotiation of Availability may be superior to the “publish/subscribe” model.
