Mobile learning technologies and context awareness
Context awareness
• What can we do with it? Deliver appropriate content Customise content, interface and interaction
– level of detail– order of presentation– appropriate display on different devices
Recommend and offer services and options– e.g. communication, databases, web sites
Enable appropriate activities– e.g. collaboration, physical movement
Mobile learning technologies and context awareness
Aims
1. Support users of mobile devices without distracting their attention from the task or environment
2. Allow relevant content (including learning objects and services) to be selected, filtered, and passed to the user
3. Enable users to either engage with the content or select other content from the filtered set
4. Provide users with detailed information about the current derived context model and allow them to change it
Mobile learning technologies and context awareness
Context Model
• Purpose: Context enables appropriate action - in this
case learning
• Process:Context = a dynamic and historical process……constructed from context states…… which are constructed through interaction
between actors, situations, objects and activities... etc

relevant to the current focus of learning and desired level of context awareness
Context StateElements from the Learning and Setting at one particular point in time, space, or goal sequence

Making it easy
• Developers/content creators can define: Context features
– what do they look for– what do they do when they find it
rank +/- n exclude link to another feature
Links– pairs of context features that pass:

CAGE at Nottingham Castle
• Context awareness: which painting? how long? been there before?
• Highlight links between paintings
• Encourage physical movement

Desktop Authoring System
• Import map image• Scale map to GPS
coordinates• Associate
multimedia with regions on the map
• Create tours linking map locations
Mobile learning technologies and context awareness
CAERUS client
• Show map based on current location
• Show an pointer to the next location on the tour
• Multimedia content automatically ‘pops up’ when you enter a region
• Use menu to explore more detailed content
