Sensor Logger Introduction This application records any changes in your phone\'s accelerometer and magnetic field sensors over a period of 50 seconds. The purpose is to automatically determine what activity you are performing (such as walking, standing or sitting). Once 1,000 entries have been recorded (around 50 seconds), the data will be analysed to try and determine your activity. You can then say whether or not this is correct, and submit the data and the verdict to a website in order to help improve the software in the future. When you click Begin there will be a 10 second delay to allow you to put the phone in your pocket or usual carrying place. After that, data will be recorded for approximately 50 seconds. You\'ll hear a beep when it\'s done. Begin Starting in... Put the phone away and wait for the beep! Error: disconnected from service Recording... Analysing...
