How to implement custom gestures in visionOS

To implement custom gestures in visionOS, you can follow these guidelines from the session "Explore game input in visionOS":

Design Intuitive Gestures: Ensure that any custom gestures you create are easy for players to learn and remember. They should be a natural fit for the actions in your game, making them intuitive for users.
Provide Feedback: When designing custom gestures, it's important to provide feedback to the player to confirm they are performing the gesture correctly. This can be done through visual effects and sounds.
Use Full Hand Skeleton Tracking: visionOS provides access to full hand skeleton tracking through ARKit. This allows you to define custom gestures by tracking the positions of hand joints in world coordinates.
Example of a Custom Gesture: For instance, to create a circle-shaped gesture, you can check the distance between the tips of both index fingers and thumbs. If the distance is smaller than a certain threshold, the gesture is recognized, and your game can respond accordingly.
Mix with System Gestures: You can combine system gestures with custom gestures within the same game to create a seamless experience. This allows for creative and flexible input methods.
Consider Accessibility: Always provide alternatives for players with different abilities. For example, offer options for one-handed play if your game typically requires two hands.
