Force-Plate Actometer Acquisition System
The Force-Plate Actometer, invented by Stephen Fowler, has been an active part of many research efforts at KU and elsewhere.
This IDL effort was directed toward replacement of the data acquisition system and providing a Real-Time Graphical User Interface (GUI) for it. The new acquisition system is less expensive, equally precise, and has the convenience of a USB connection.
The new Graphical User Interface, rTrack, provides real-time visualization and interaction.
