Export accelerometer measures

هذا التطبيق يسمح لك أن تأخذ التدابير التسارع مع جهازك.

This app allows you to take accelerometer measures with your device, and export them by email as text. The minimum period of acquisition of the data is 0.01 seconds approx. This app allows you to set the period of acquisition and the total time of the acquisition.

You can use the text data as you please but I recommend to use Excel or any similar application and click import data from text and paste the text. You can alternatively also paste the raw text from the email to a .txt file and import it in Excel, the data will appear organized, in columns.

More precisely this app returns the Linear acceleration which is the acceleration of the device minus gravity acceleration. It returns the three coordinates of the acceleration of your device as specified in the android developer guide: "In general, the sensor framework uses a standard 3-axis coordinate system to express data values. For most sensors, the coordinate system is defined relative to the device's screen when the device is held in its default orientation. When a device is held in its vertical and most common position, the X axis is horizontal and points to the right, the Y axis is vertical and points up, and the Z axis points toward the outside of the screen face. In this system, coordinates behind the screen have negative Z values."
