Hi to all,
I am new to the Android world and was thrown in by a project I am working on that logs sensor data on the device using the gps and accelerometer and then this data is sent to a database. The data recorded will be mapped so that if a crowd is formed in a certain place this is identified.
At the time the data is sent after a period of time and by using a connection to the laptop with the database.
I have looked at the Sensor simulator on OpenIntents.org and saw the data generated when the device is moved.
What I would like to ask is how to interpret the data produced by the accelerometer to know if the person carrying the device is walking. If the device is in a pocket will the accelerometer data change?
I know that the most obvious sensor to use is the GPS but if the person is in a bad gps reception area it will be a problem to get accurate reading, hence the use of the accelerometer.
In more open spaces, the GPS will be used to fine tune the location and with a timestamp the person's velocity may be computed so it can be known that that person may have encountered a crowd that is blocking or restricting easy flow.
The app will be tested on Nexus One's as they are available for the project.
Thank for any help, anyone may give. I also appreciate if links to other threads are given if no first hand help is at hand. Thanks.
