ONLY FOR NEXUS 4 AND 5
PLEASE DO NOT RATE POORLY, READ FULL DESCRIPTION.
This app allows you to tune the vibration of your device at your own taste. As many of you have noticed, devices like Nexus 4 or Galaxy Nexus have a very quiet and discrete vibration, this app will allow you to turn it up a noch and personalize the feedback your device gives you.
Not every device is supported, the APP itself will detect and let you know if you can tune the vibration or not.
THIS APP REQUIRES:
Android 4.0.0 or newer
Root access -if not, the app can not change the default vibration-
A compatible device
(Mostly Nexus 4 and 5 devices, other may or may not let you set the vibration intensity, since this APP is developed to work with the vibration units that LG are using right now, if your phone DOES NOT HAVE ONE OF THOSE, will NOT work)
Please email me if you find a bug or want to make me any other comment or feature request.
If you like Vibration Widget, please consider installing my other app, Profile Widget, which can do the same as Vibration Widget and a lot more (control vibration, volume, connectivity, screen settings, ...) in a single widget.
Profile Widget Lite: https://market.android.com/details?id=com.cygnus.profilewidgetlite
Profile Widget Full: https://market.android.com/details?id=com.cygnus.profilewidget
You have to add the widget to one of your home screens to use it. Just long press on an empty space of your home screen or press the Menu Key and select Add -> Widgets to show a widgets list in which you can choose Vibration Widget.
shows reference to earthquake vibrations as classified by Mercalli intensity scale.
Vibrations are shown in all directions: X, Y, Z in different colors.
Place your device on stable surface and measure vibrations.
Mercalli intensity scale
I. Instrumental - Not felt. Recorded by seismographs.
II. Weak - Rarely felt, usually only on top floors of high buildings.
III. Slight - Felt indoors, like a passing light truck.
IV. Moderate - Windows, dishes, doors rattle. Like passing train.
V. Rather Strong - Felt by all. Small objects upset.
VI. Strong - Books off shelves. Trees shake. Isolated damage.
VII. Very Strong - Difficult to stand. Many poor buildings damaged.
VIII. Destructive - Significant damage. Branches broken from trees.
IX. Violent - General panic. Serious damage. Ground cracking.
X. Intense - Most buildings destroyed. Rails bent slightly.
XI. Extreme - Rails bent greatly. Pipelines destroyed.
XII. Catastrophic - Near total damage. Objects thrown into the air.
-Use the manual mode to make the phone vibrate while pressing a button
-Use the auto mode to turn your phone into an automatic vibration device! Set up your own custom vibration patterns and run them either once or infinitely!
Enjoy. If you have any questions, comments, or suggestions, please email email@example.com or tweet @anthq!
Vibrations visualizes current accelerometer sensor data, performs a Fast Fourier Transformation (FFT) and displays the results in an histogram. The dominant frequency (peak of the histogram) is highlighted. In the settings the accuracy of the fft can be adjusted in a range from 0.0625 Hz - 1.0 Hz. Results are shown in a separate tab for each axis.
Warning: High accuracy of the fft causes heavy load on the cpu. It may disturb the results!
For example, it can be used
• To measure the acceleration of a vehicle.
• To measure the vibrations caused by a vehicle (indicates the comfort level of this vehicle).
• To measure the inclination of a surface.
• As a quick assessment tool to measure how intense are the vibrations produced by a product you are going to buy.
• In any other professional or even fun usages you can think of.
• Time Domain Analysis
Shows the magnitude of vibrations or the acceleration over time.
• Frequency Domain Analysis
Displays a graph showing the measured frequencies on the X-axis and the magnitudes of each frequency on the Y-axis.
• Time Domain Parameters (Advanced)
Calculate features of the acquired vibration samples (Minimum, Maximum, Average, RMS, Variance, Skewness, and Kurtosis).
• Analysis can be done on the X,Y, and Z directions.
• Save snapshot of current analysis graph.
For any feedback, bug reports, or required features, please send an email at firstname.lastname@example.org.
Strobe Light and Flashlight
- Strobe your device's screen and/or flash LED from 1 - 30 Hz. Strobing helps one to see objects vibrating too fast for the eye to see.
- Turn your device's screen and/or flash LED into a flashlight; this makes a conveinient flashlight during test setups.
- NOTE: Not all device's LED flash can be controlled by the VR Mobile app.
- Remotely control VibrationVIEW from within the VR Mobile App (while on the same network).
- Start/Stop tests
- View graphs
- Adjust amplitude and frequency
Max Acceleration Calculator:
- Calculate the maximum amount of acceleration that a shaker (from a database or user input) can output based on the mass added to the system.
- Convert Acceleration, Force, and Mass units to and from common units.
- Based on sinusoidal motion, calculate Acceleration, Frequency, Velocity, and Displacement by inputting any two of these values.
- Pick between two impact types: Plastic or Elastic, and the pulse type. Shock Calculator will find the remaining two values given two inputs: Acceleration, Impact Time, Velocity Change, and Height Change.
- Measure minimum, current, and maximum dB from your mobile device's microphone. Note: A device must have a microphone in order to use this feature.
- Measure minimum, current, and maximum acceleration in each of your mobile device's accelerometer axes.
- Zero out acceleration to calibrate for an uneven surface.
- See Vibration Research's building on Google Maps (or any other map application installed on your mobile device).
- Call, fax, or email VR directly from the app.
- Watch YouTube videos from VR.
- Visit VR's website.
- View VR's 9500 Revolution Vibration Test Controller, and the ObserVR portable DAQ.
