Multitouch Control of Holographic Optical Tweezers - Sorting Beads

Here we demonstrate multitouch control of the holographic optical tweezers and the ease with which a user can manipulate large numbers of optical traps in real time and with great finesse.
Grouping of traps and transformation of said groups is also shown.

Yep, we use LabVIEW for our control environment. We're in the process of releasing a version of our multitouch control library for LabVIEW now. It will enable anyone to add multitouch functionality to their LabVIEW code.

awesome! and many questions (hints):

Do you use a graphical interface (graphic card) or pc processor? because i am thinking in the refresh rate to calculate the hologram every time. how many nucleus you use in your hardware?
