In this Gem, you will learn how to set up a basic bi-manual (two-handed) interaction, specifically through object manipulation and selection/manipulation of a selection volume. These techniques will be demonstrated using a LEAP Motion Hand Tracker, standard game controllers, and Android-based mobile devices. The programming code in this chapter has been tested with Unity (v 5.6.1f1), using MonoDevelop (v and Android Studio (v 2.3.1), though your solution is not limited to this compiler or Unity version.
