custom hand gesture vision

To create custom hand gestures in visionOS, you can utilize the full hand skeleton tracking provided by ARKit. Here are some key points on how to define and implement custom gestures:

1. Hand Skeleton Tracking: You have access to full hand skeleton tracking, which allows you to get the positions of various joints in world coordinates.

2. Gesture Definition: For example, to create a circle-shaped gesture, you can check the distance between the tips of both index fingers and both thumbs. If the distance is smaller than a certain threshold (e.g., 4 units), the gesture is recognized.

3. Combining Gestures: You can combine system gestures with custom gestures within the same game. This allows for a more intuitive and seamless user experience.

4. Feedback Mechanism: When designing custom gestures, ensure that players know they are performing the gesture correctly by providing appropriate visual and auditory feedback.

5. Accessibility: Consider building alternatives for players with different abilities. For instance, provide options for one-handed mode if your game typically requires two-handed input.
