collision detection
Crash avoidance system
Collision detection is the computational process of determining when two or more objects in a digital space intersect or touch.
Essential in video games, physics simulations, and robotics, it governs whether a character can walk through walls, whether bullets hit targets, and whether virtual objects behave realistically: The game's collision detection is broken—I keep falling through the floor.
