+While this research is going on, there has been a huge expansion in the
+ ownership, use and power of mobile telephones.
+ Mobile telephones are so ubiquitous and now come with such a large sensor
+ platform that they are the obvious choice for implenting activity-aware
+ technologies for use in day-to-day life.
