Apple considering small in-home wireless sensors?
Here's information on an Apple patent (from a former MIT'er) for little
wireless sensors that communicate with phones about activity in home/life:
These types of sensors could be used for automatic activity/context
detection that would provide powerful information for context-aware
experience sampling.
At MIT we've been considering this type of thing for a while and see great
potential. See
