Download the Android smart phone application AvocadoAC340k 

You will need to allow installation of non-Market applications on the Settings/Applications menu on your handset.


To continuously measure physical activity, classify activity by type and quantify activity intensity using the sensors of a smart phone.  Once known sports training activities are detected the specialist application Google MyTracks is invoked to record and analyse activities in more detail. 

 This information can be used to:

  • Provide life-style information on total exercise, health and activity levels.
  • Infer further lifestyle information by combining with other information sources, for example location data.
  • Provide context to reduce data gathered and data management problems for sports tracking by only gathering high bandwidth data when it’s likely to be useful.


The smart phone is an attractive platform for context-awareness because:

  •  People carry mobile phones around in their day-to-day lives.
  • Activity monitoring can run as a background application
  • Smart phones are becoming ubiquitous.


Battery life can not be significantly impacted.

Mobile phones are carried and used in a variety of ways.

Different model Android phones have different functionality. In particular some models disable the accelerometer when the screen is off. Therefore AvocadoAC will fail on some devices. See the list of tested handphones
