Kinect 4 ... holographic optical tweezers

The 3D position and orientation of a microtool confined in multiple optical traps needs to be controlled in order for one to perform modern, challenging experiments; for example, in order to utilize it as a scanning probe and investigate the surface of optically sensitive cells. The control interface has traditionally used the keyboard/mouse combination-limiting manipulations to a series of 1D/2D transforms. In this paper we demonstrate how the Kinect can be utilized to control the position and orientation of a microtool utilizing macroscopic models.
