qc_open_library('quarc_library_beta/Devices/Third-Party/Leap Motion')Description
The Leap Motion block can be used to read linear velocity, rotation matrix and scale factor from Leap Motion detector. Also each output associates with a probability value for the user to distinguish the motion.
By default, the Leap Motion block uses right-handed coordinate system as shown below:
Limitations
Only one device supported!
This block only supports one device attached to the PC target.
Installation Requirements
In order to use the Leap Motion block, the Leap Motion driver version 2.3.1+31549 as well as development kit version 2.3.1+31549,
must be installed. Add the directory containing the Leap.dll file to the system PATH environment
variable, e.g. C:\Program Files\LeapSDK\lib\x86 for 32-bit Windows, or
C:\Program Files\LeapSDK\lib\x64 for 64-bit Windows.
Input Ports
This block has no input ports.
Output Ports
lin
outputs the linear translation of hand motion from the previous sample.
lin_prob
outputs the probability that the motion is a linear translation. The value ranges from 0 to 1.
rot
outputs the rotation matrix of hand motion from the previous sample.
rot_prob
outputs the probability that the motion is a rotation. The value ranges from 0 to 1.
scale
outputs the scale factor of hand motion from the previous sample.
scale_prob
outputs the probability that the motion is a scalar movement. The value ranges from 0 to 1.
con
indicates if the Leap Motion device is connected.
err
outputs error.
Parameters and Dialog Box
The Leap Motion block has no parameters.
