- Fast pointer movements can skip over elements in hover detection, similar to game physics tunneling issues.
- The problem arises because pointer positions are sampled discretely, leading to gaps where hover events are missed.
- A solution from game development involves testing the line path of the pointer instead of just its point position.
- Using the slab method, which checks intersection of the pointer's path with element bounding boxes, improves hover detection.
- Implementing this with Motion APIs allows for continuous hover detection, even with fast pointer movements.
