Apple is recently investigating the use of context and contextual sensors for contextual marketing (see report from AppleInsider http://is.gd/ciEmm ). This is doing a lot of stuff we have been exploring the Learning Media Lab about using barcode scanners, RFID readers, location tracking indoor and outdoor for filtering content for the current context of the user. The description includes also different aspects as personalisation and contextualisation. So I wonder if one could use the the iAd framework not only for selling advertisements but also learning nuggets ?
