I would like to use gestures with a d415 to control video displays in the same way a mouse would.

Are there any such programs in existence.

You may be able to achieve your goal with software called Nuitrack

Here is a link to a gesture recognition demo with Nuitrack and RealSense D415.

​Well known RealSense developer UnaNancyOwen has produced a Nuitrack sample program that includes gestures.
