BubbleLevel Silverlight is a simple WP7 Silverlight application that uses
accelerometer sensor information to calculate the inclination of the device
and presents this as a traditional Bubble level. The application provides a
calibration feature to handle any possible errors in accelerometer readings.
The application is rewrite of the QtBubbleLevel application written in Qt for
Symbian and Maemo devices.
PREREQUISITIES
C# basics
Development environment ‘Microsoft Visual Studio 2010 Express for Windows
Phone’
KNOWN ISSUES
None.
BUILD & INSTALLATION INSTRUCTIONS
Preparations
Make sure you have the following installed:
Windows 7
Microsoft Visual Studio 2010 Express for Windows Phone
Launch Bubble Level on your device. The bubble in the glass tube will show
the level of the device’s x-axis relative to gravity. When the device is
tilted to either direction 20 degrees or more, the bubble will be at the
corresponding end of the tube.
The accelerometer sensor of the device can be calibrated by pressing the tool
icon beside the QtBubbleLevel sign, placing the device on a level surface, and
tapping the Calibrate button. The calibration data will be saved into the
device’s memory and it will be applied on the next startup of the application.
ACCELEROMETER
The application heavily bases on accelerometer sensor. Please follow the link
below for instruction about using accelerometer in applcations. Accelerometer can
be also tested now on the Windows Phone Emulator.
