Acceleration Explorer will plot the acceleration sensor outputs in real time to the screen. The acceleration sensor outputs can also be logged to a .CSV file and be opened in any spreedsheet application. Analog gauges of the acceleration and rotation of the device are also displayed to help further visualize the acceleration sensor outputs. Acceleration Explorer allows users to investigate the noise, offset and skew associated with the accelerometer sensor on Android devices. After a quick calibration process, Acceleration Explorer will calculate the magnitude of each axis and the noise associated with it. Acceleration Explorer also determines the minimum and maximum amplitudes of each axis along with the update frequency of the acceleration sensor. Acceleration Explorer makes it easy to compare the performance of the acceleration sensors of multiple devices.
Acceleration Explorer was created with the intent of writing better applications that rely on acceleration sensors. However, it can also be useful to students and hobbyists who are interested in how acceleration sensors work. Acceleration Explorer can help fine tune your acceleration sensor algorithms, especially low-pass filters, mean filters and normalizing sensor outputs.
Examine the sensors noise density. The noise density, denoted in units of ug/sqrt(Hz), is defined as the noise per unit of square root bandwidth and can be used to determine the expected noise output from a sensor.
Measure sensor offset. Offset occurs when the same measurement, say gravity, is taken with both the positive and negative axis of an accelerometer sensor and a difference is apparent in the measurements.
Visualize the devices tilt and rotation angles in real-time based on the acceleration sensors measurements. This makes it easy to get a sensor for how well the acceleration sensor measures the tilt and rotation of the device.
Log the acceleration sensor outputs to an exernal .CSV file. These files can be opened in any spreadsheet application allowing you to perform any analysis of the data that you might want to see.
