Resolution

Definition

In the context of haptic interfaces and related technologies, resolution refers to the smallest change in a physical parameter that can be detected or produced by a sensor or actuator. High resolution means that the system can sense or control very fine changes, which is crucial for accurate feedback and interaction.
