by 2004, we may have 1 billion users of internet, 40% of those may be using a wireless device to retrieve internet data
wireless trends
- messaging services
- mobile commerce
- mobile gaming
- location based services (LBS)
-- pull, push
LBS: applications that react according to a geographic trigger based on the
position of a mobile device anywhere anytime
- AKA: whereware, location aware computing, location finding technologies,
etc....
24 GPS satellites, move around the early twice per day, need info from 3 satellites to find lat and long, if you want to know altitude you need a 4th sattelite
can use traditional wifi networks to find location of users as well
LBS by 2005 all cell phones will have enhanced-911 capability
- can do proximity searching
as humans we are not used to broadcasting our location all the time
in Finland, legislation is being considered that will let parents monitor the location of their children without their consent

another application: can track vehicles, determine who is driving, the speed of the vehicle, etc
also: can use digital fences to have house arrest
DOD locating soliders, vital signs, tracking
England: have Zingo (to hail a taxi, they know where you are and you can know where taxis are, shortcut, less taies)
MS: SPOT - smart personal objects technology using FM technologies
- time auto adjusts, info about weather, etc
- uses FM radio frequencies
GPS drawing
- can walk in a city with a mobile device, as you walk through the city you
can make shapes and share those with people
- can do that by air or sea also, some people are sharing these types of drawing
mobile commerce (M-Commerce)
- mobile wallet, device knows who we are and what we want
Learning Paradigms (Sussan Wheeler)
- learning paradigm = accepted framework of teaching and learning
1- situated congnition: not based on classroom outline, more situational and context based
2- paradigms of online learning
-- autoomous learning: e-reading, self paced
-- online apprenticeship
3- Inquiry based learning
-- learning ocurrs best when person is seeking that information (Montesourri
method)
-- encourages learners to pursue their learning based on their interests
SUGGESTING NEW LEARNING PARADIGM
- seek information based on location
- facilitator is the mobile device which is LPL capable
- learners dictate what they want to know in reference to location
- learner is in control of line of inquiry and be subject to type of info they
have based on "location specific knowledge base"
- for JILL to be a reality, design of databases must be indexed by location
me: this reminds me of map indexing engine in development by TTU Vietnam Center
a standard for encoding location must be defined and used
- open LS is currently being considered for use in XML tags
JILL examples
- provide the istory of a building to an active learner
- geographical location is determined
- surrounding area of the learner is identified
- JILL identifies the location, displays topics for learning opportunities,
info about accessiblity
Potential JILL opporutunities
- historical (location-based) timelines
- learners request historical data based on location
-- request details about the buildings around them
-- see the evolution of the structure
-- read anecdotes on the personalities living in the building
-- review events
Timeline
- a visit to the White House, see the modifications over time
Other
- in geology, visualization of physical evolution of the area
- weather, historical weather patterns, unusual weather events, forecasts
- health: health hazards alerts
- Ecosystems: learn about flora and fauna, evolutionary patters, environmental
issues: pollen count, or air and water pollution
Just in location learning
- empower lifelong learners to acquire
embedded metatags in XML (xyz coordinates) so that devices can pull those coordinates
