2. Mobile Communication email ubiquitous wireless technology pervasive
increasing ways of being contacted
increasing pace of communication
desire to communicate at any time and place
information overload and continuous interruptions

3. Challenges
Everywhere Messaging - the ability to send and receive messages
all the time
minimize interruption
adapt to user
location awareness
user interface

4. How many times have you gone to the grocery store but left
: a context-aware communication system
How many times have you gone to the grocery store but left
the shopping list on the refrigerator door?
Wouldn’t it be more efficient to have a reminder to buy
groceries and the shopping list delivered to you when you
were in the vicinity of the store?

5. Context - awareness
The ability of the computer to sense and act upon information
about its environment.
location
time
temperature
user identity
user activity

6. Location-learning agent
user tracked via GPS
salient locations automatically determined
latitude/longitude translated to virtual location
to-do list associated (site specific or shared)
no bootstrapping necessary

7. Deliverables reminders to-do lists messages Web content
delivered in a timely manner
when in the relevant context
triggered by user’s geographic location

8. Speech Interface mobile hands/eyes busy
core functions have speech interface
- auditory cues
- speech recognition
- text-to-speech synthesis
- audio playback
