Messaging and alerting Chris Schmandt MIT Media Lab

How much? interruption is essential in work and play just what we want and when we want it if too much, users will disable it tradeoff: benefit vs. annoyance

What can we do? filter messages adapt to user location aware augment sensory environment appropriate user interface

Filtering which messages arrive at async device? presentation order for synchronous reader - especially non-GUI rules: regular expressions by-example while reading how do rules age/expire? what does my computer know about me?

sent log outgoing call log address book –links , phone numbers, location calendar geographic location updated hourly (Unix cron) CLUES - dynamic filtering

How do we use CLUES? Message order and grouping for voice access over phones –Mailcall –Phoneshell –“You have three important messages and two timely ones” Voice alerting in office (finger or active badges) Selecting for forwarding to pagers, etc.

InternetDesktop Computer Pager Knothole Stefan Marti Speech Interface Group E Intelligent Paging

Knothole messaging filters incoming using CLUES proxy hides my outgoing address –recipient’s privacy –sender knows only one address replies originate to any internet address originate via address book –NOT a special local pager app

Knothole as PDA structured messages rolodex lookup calendar read/write local data (dictionary) web data (news, weather, traffic, stocks) Unix command line

Active Messenger

guarantee delivery of important messsges work in concert with other access –reading mail on the console –IMAP remote access –telephonic reading (Phoneshell) throttle delivery when less reachable across a variety of devices

Devices pagers –local, Skytel, Iridium,SMS to phones text-to-speech over phones –wireline, portable fax screen reading

Operation monitor device access –which pager –caller ID –finger, etc. track messages –device delivery status –reply status (via proxy service) model user activity / location

Why multiple devices? coverage cost of service support heterogeneous networks and multiple access modalities real goal: What is user’s attentive state? a process, not just a routing table

comMotion location aware computing messages and reminders learns user’s locations GPS auditory interface for driving

Issues reliability of GPS tracks learning algorithms route detection/deviation/projection privacy –client based –might reveal to family/friends?
