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 email log

• outgoing call log

• address book– links email, 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.

Knothole messaging

• filters incoming email 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

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

comMotion demo

Issues

• reliability of GPS tracks

• learning algorithms

• route detection/deviation/projection

• privacy– client based– might reveal to family/friends?

Nomadic Radio

• wearable audio

Nomadic Radio

• more effective alerting– voice cues– content, subject lines

• adaptive– user responses to stimuli– presence of speech/conversation

Nomadic Radio

• scaleable audio
