Journey analysis system and method
| DWPI Title: Mobile computing device i.e. mobile telephone for determining location of individual, has processor for powering off sensor, and for performing computing operation based upon estimated location of user of device in predefined travel segment |
| Abstract: The various technologies presented herein relate to determining a location of an individual, or an object, when a GPS may be unavailable/occluded. Readings from a plurality of sensors on a mobile device can be generating a plurality of data (e.g., speed, motion, temperature, biometric, etc.) which can be combined to generate a probability of a user of the mobile device being at a particular location, or not. Sensor readings can be weighted to enable sensors having a large effect on a degree of confidence of the probability of the user being determined to be at a location being given priority (e.g., battery priority) versus those sensors which have lesser effect on the degree of confidence. With the user determined to be at a location, information, a notification, an instruction, etc., can be presented to the user, via the mobile device. |
| Use: Mobile computing device i.e. mobile telephone (claimed) for determining a location of an individual or an object using a global positioning system. |
| Advantage: The device reduces transmission of periodically packaging sensor data from multiple sensors into a single data packet over a channel, and conserves battery life of a battery. The device maximizes probability of a data analysis system to correctly determine an activity of the user. The device presents a request on the device requesting the user to enable improved identification of the user location of the users. |
| Novelty: The device (130) has first sensor for outputting first sensor signal that is indicative of first parameter. Second sensor outputs second sensor signal that is indicative of second parameter. A processor (141) powers off the second sensor, while continuing to provide power to the first sensor in responsive to detecting that a battery defines low power state, where the second sensor is powered off based upon weight assigned to the second sensor signal being less than another weight assigned to the first sensor signal. The processor estimates the location of a user (110) of the mobile computing device in a predefined travel segment of the predefined journey subsequent to powering off the second sensor based upon the first sensor signal. The processor performs computing operation based upon the estimated location of the user of the device in the predefined travel segment. |
