B4A Library NewHandwave - detecting hand motion (left, right, up, down) with front facing camera

Johan Schoeman · Oct 22, 2016

I came across this Github project and thought it might be interesting to see if I could "shortcut" wrap it and make it work "from B4A".

The B4A library files are too large to post here. You can download them from here:
https://www.dropbox.com/s/83w5g8tolgd4n31/NewHandWaveLibFiles.zip?dl=0

...or you can download the B4A generated APK files from here and install the trial app:
https://www.dropbox.com/s/1s6d15owfkqzldd/b4aNewHandWave.apk?dl=0

You need to enable AppCompat V3.20 and DesignSupport V2.00 to make use of this app.

Start the app and then move your have from left to right, right to left, bottom to top, and top to bottom over the front facing camera (about 15cm or so above the camera) - it should report the detected motion via a toast message.

Extract resource.zip, DemoRes.Zip, and LibRes.zip and copy the folders with their contents to be on the same folder level as that of the /Files and /Objects folders of the B4A project

Have tested this on S4 mini with KitKat and also on a device with Lollipop.

I will spend some time on it and try to convert this to a library that can be used 100% from within B4A - but this posting just to demonstrate the motion detection via the front facing camera

I can´t use this 3 parameters AFTER loadlayout because this error (with hv in layout)

This last error is in load layout when creating HV object

I will spend some time on it this coming weekend to trace the logic in the library and see if I can sort it out. Just for interest sake - what happens when you do this to Activity_Create:

B4X:

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
   
    hv.ExposureCompensation = 2
    hv.Enable_ISO_setting = False
    hv.EnableWhiteBalance = False
       
    Activity.LoadLayout("main")
    'hv.Initialize("hv")
    hv.ShowToast = False
   
End Sub

Hey Johan,

Now works with Nexus 4!

But, I tried with Samsung S4, Samsung S5 and Nexus 4 and all of them not recognize VERY WELL, in 80% when you pass your hand in front of camera, NOT start the events, in rest of 20% works but sometimes when you pass your hand to up, start left, or down....

Maybe some problem in original library.... I don´t know

Don't move your hand too fast past the camera, be at least 10 to 15cm away from the camera, and beware of casting a shadow over the camera from different directions as what you hand is moving. It will confuse it to death...

I have tried a different library but even the APK crashes. So, this is the next best that I could find. Library makes use of .so files so will have to check the Java code and see if I can find where it actually tries to recognize the hand movement.

But for me this is more about the principle of what could be done than anything else. Will nevertheless see if I can find something.

look this

I tried with 5,10,15 and 30cm

Alberto, it is not the wrapper - it is in the original code where it tries to recognize the hand movement.

Alberto, will you please run the attached B4A project and then copy and post the string that it writes to the B4A log (using your Nexus 4). The attached project uses inline java code to extract a whole lot of info about your camera. Please note that I have set....

B4X:

mCamera = Camera.open(1);

....in the inline Java code to get the parameters of the front facing camera (ID = 1)

You need to make sure that the JavaObject library (I have version 2.05) are enabled and take note of permission added to the B4A manifest file

B4X:

AddPermission("android.permission.CAMERA")

This is for eg what my Vodaphone (Lollipop 5.1) returns:

Here is a link to new library files (https://www.dropbox.com/s/6wms8ls0rszwgl8/NewHandWaveLibFiles_V_1_03.zip?dl=0). Also see the attached B4A project.
From your data dump it seems to me as if you should use:

B4X:

    hv.IsoParameterName = "iso"           'see popup help when using these two methods for possible values and also the B4A Log.....
    hv.IsoParameterValue = "ISO400"          '.....for what your camera(s) support (values returned by the inline Java code)

Change the code in the attached B4A project to the above and see if it runs/crashes.
