Hello Developers,
Here I have an exciting example which allows you to control your mouse cursor by tracking hand movements with a camera.
The VI makes use of the powerful IMAQ Optical Flow VI from the NI Vision Development Module to track location changes of pixels over consecutive frames.
From here, the program can be simply used to draw crosshairs on your hands and track their movement.
Alternatively, if the Control Mouse Mode (Control) on the Front Panel is True, then a user can take advantage of this feature tracking to interface with Cursor movement and simulate a Left-Click Event.
Instructions:
1. Select your Camera Hardware then run the VI and place your hands in the highlighted areas. Be careful the image is mirrored!
2. This will track your hand movement on-screen whilst drawing crosshairs on the points being tracked.
3. Stop the program and restart with the Control Mouse Mode (Control) set to True. You will go through the same 5 second hand calibration process as before however this time your Front Panel will become Transparent.
4. Now, your right hand movement will control the cursor whilst shaking the left will click!
5. If either of the tracked points go out of the camera's field of view you will be prompted to re-calibrate.
Have Fun!
