Our patented mobile technology is highly effective and efficient in detecting the context of mobile device user - especially driving a car (it is being used in SpeedAlarm application)
To save device battery life during driving pattern detection, number of groups of sensors are used in a hierarchical way. The low-energy sensors are used first. If the result is positive it activates next group of sensors in a hierarchy. If the result is negative next group of sensors are not activated at all. In effect system can determine driving patterns with high accuracy and in low energy consumption way.
We created dSense SDK for Android platform. This approach allowed us to create a solution "out of the box", which you can easily and quickly integrate with other applications.
