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
Challenges
Everywhere Messaging - the ability to send and receive messages
all the time
• minimize interruption
• adapt to user
• location awareness
• user interface
: 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?
Context - awareness
The ability of the computer to sense and act upon information
about its environment.
• location
• time
• temperature
• user identity
• user activity
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
• reminders
• to-do lists
• messages
• Web content
delivered in a timely manner
when in the relevant context
triggered by user’s geographic location
Deliverables
Speech Interface
• mobile
• hands/eyes busy
• core functions have speech interface
- auditory cues
- speech recognition
- text-to-speech synthesis
- audio playback
