Advanced Hand Calibration

Deprecated. Our hand-tracking system requires each new user to go through a hand calibration process to build a user profile. This process should take about five minutes and only needs to be done once ever. If the camera setup changes or the cameras are recalibrated, only the last (automatic) step of this process needs to be run again to update the profile. You should never have to go through the hand calibration for the same user twice.

1. Run the hand shape calibration for a new user:
   Windows: handcalibration.bat shape NewUserName
   Mac: ./handcalibration.sh shape NewUserName

   The hand shape calibration program captures a 3D scan of your hand and builds a hand model to fit the scan. Press space bar and spread out your fingers wide apart to begin. The scanner will start acquiring your hands when they are held still. If the shape calibration is successful, press 'q' to quit. Otherwise, press space bar to re-scan.

2. Run the hand pose calibration for a new user:
   Windows: handcalibration.bat pose NewUserName
   Mac: ./handcalibration.sh pose NewUserName

   The hand calibration program needs to scan your hand in several poses. Each pose is shown in the bottom left corner. You don't have to reproduce the poses exactly. Rather, do what feels comfortable or natural to you.

   For each of the poses, do the following:

   Place both arms on the desk, parallel. Raise the hands so that the arms form a 30 degree angle with the desk, and rotate the forearms slowly and continuously (See Video 1). Press space bar when you are ready to record this rotating motion.

   After recording each scan, the pose calibration will calibrate a hand model to the scan. If the calibration is successful, press Page Down to continue. If there are problems with the scan or calibration press space bar to re-scan.

Once you have generated a custom hand profile, you can launch the hand tracking server with,
Windows: nimble_server.bat NewUserName
Mac: ./nimble_server.sh NewUserName
