【實用工具app】Acceleration Explorer|最夯免費app-綠色工廠好玩App

Acceleration Explorer plots the output from the acceleration sensor in real-time allowing you to visualize the devices acceleration. You may also view the acceleration as a two dimensional vector and save the sensor data to an external .CSV file which can be opened and viewed within any spreadsheet application. The tilt and acceleration of the device are also displayed on analog gauges allowing you to further visualize the behavior of the acceleration sensor.

Acceleration Explorer allows the user 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.

Why would you want to know about noise, offset and skew?

We want to know about noise, offset and skew because they are aspects that make the sensor less accurate that we can partially compensate for. For example, you may want to implement a low-pass filter or mean filter to smooth the acceleration sensors output and knowing how much noise the sensor has is very useful. Or you may want to know how accurately your device measures gravity, tilt or acceleration.

Compare devices!

Acceleration Explorer makes it easy to compare the performance of the acceleration sensors of multiple devices. Not every Android device is the same and knowing the range of how acceleration sensors perform can be very helpful.

Write better code!

Acceleration Explorer can help fine tune your acceleration sensor algorithms.
