This document discusses working with location services and device sensors in mobile applications. It covers getting location data through GPS and setting accuracy levels. It also discusses using the Bing Maps API and integrating maps into apps. Regarding sensors, it describes how to use the accelerometer, compass, gyroscope, inclinometer and other sensors to gather motion and orientation data and provide examples of applications. The document is intended to demonstrate how to implement these features in mobile apps.

- 2. Overview Location Maps Device Sensors Accelerometer Compass Gyroscope Inclinometer
- 3. Location Location improves experience Facebook Foursquare Map apps Longitude and latitude coordinates Enable ‘Location’ under the capabilities Can define accuracy levels Rich emulator support
- 4. Demonstration HOW TO WORK WITH LOCATION SERVICES
- 5. Location: Running in the background Examples Location reminder Location tracker Runs 4 hours without user interaction Battery saver and device memory issues User disabling location Another app starts running in background
- 6. Maps Fully fledged Bing maps support Need to have a Bing maps key bingmapsportal.com Location and address Routes and directions Integration with other apps for directions
- 7. Demonstration WORKING WITH BING MAPS
- 8. Device Sensors Accelerometer Gyrometer/ Gyroscope Compass/ Magnometer Inclinometer Orientation Sensor Ambient Light Sensor Proximity Sensor
- 9. Device Sensors: Accelerometer Acceleration caused by the gravity or other external forces Device rotation and motion changes X, Y, Z values
- 11. Device Sensors: Compass/ Magnometer Returns a 2D heading with respect to magnetic north based on the horizontal plane of the earth. Should not be used in determining specific device orientation or for representing anything in 3D space. Some systems support both HeadingMagneticNorth and HeadingTrueNorth.
- 12. Device Sensors: Gyrometer/ Gyroscope Measures angular velocities along the X, Y, and Z axes. Do not concern with device orientation but device rotating at different speeds. Can suffer from noise in the data or a constant bias along one or more of the axes. Query the accelerometer to verify whether the device is moving in order to determine if the Gyrometer suffers from a bias
- 13. Device Sensors: Inclinometer Work best with apps that care about how the device is situated in space. Pitch and roll are derived by taking the accelerometer’s gravity vector and by integrating the data from the gyrometer. Yaw is established from magnetometer and gyrometer.
