Possessing the player character. Since we won't have any controllers to use and it's all driven by hand tracking, I've decided to use some context dependent UI. In this case, when you are looking at the player character, a menu will show up with stuff you can do. Right now, the only thing you can do is possess the player character. To do so, you kinda point at the UI button and click it. To click, you bring your index and thumb fingers together and tap. After doing that, you will take over the player character's body. The cool part is that all the individual fingers on the player character are also mapped to your real finger movements.
