Mobile Contexts for Information Retrieval [closed]

Question

I work with contexts for a Mobile Wiki Software. Contexts are used to serve the right information for a specific situation out of large pool of information units.

• For example: When you are at the customer, the system checks your location and presents you location based information.

• Another example: You are at the customer and the system checks your calendar to find appropriate information for your appointment there.

Which other context resources (beside location and calendar data) are used for mobile (smartphone) software?

Answer 1

I can think ok:

• incoming and outgoing phone calls with contact based information and location based information.
• call logs with contact based, call note and location based informatiopn.
• sms/mms again with into / output to calendar data, contact data and location data.
• email with into / output to calendar data, contact data and location data.
• tasks and task lists.

Answer 2

I guess address books are most important in such application.

Answer 3

browser bookmarks, preferences
