Reality mining

Tuesday, March 18th, 2008

Interesting article about reality mining. Basically it is about collecting “reality information” about people, mainly from their cell phones. For example positioning by GPS, Cell-ID, proximity to hotspots; social networks by analyzing phone logs and bluetooth proximity and so on. This is about the same thing you can do with IYOUIT, but what is explicit in this article is the use of data mining algorithms to analyze the data and factor analysis to find correlations among multiple variables. Using this they can for example “…accurately model the social networks of about 100 MIT students and professors. They could also precisely predict where subjects would meet with members of their networks on any given day of the week”.

This is an aspect to consider for personalizing learning reminders.

Location based services based on Cell-ID

Friday, March 14th, 2008

No activity here for a long time, but now it’s time to start blogging again.

Yesterday I found an interesting article about Place-Its, which might be described as mobile post-it notes that are activated on your cell phone when entering/exiting certain locations. The user can add notes and the criteria for activating the notes, such as “when arriving at work”. The positioning is based on GSM location (MCC, MNC, LAC and Cell-ID). This could be very interesting for mLearning, and relates to the concept Context Awareness, and applications such as IYOUIT and the papers written about that.

I will try to get a student to write some application about that, with the addition of a web based interface as well, and with the addition of adding links to reminders. This could be used for getting reminders of what to study in mLearning situations such as when entering the subway station. Python Series 60 is probably the best choice for developing such an application.
