Accuracy and Precision

Definition

Accuracy refers to how close a measured value is to the true value, while precision indicates the consistency of repeated measurements. In the context of input methods and interaction paradigms in immersive environments, understanding both accuracy and precision is crucial for designing effective user interfaces and ensuring a seamless user experience. High accuracy means users can interact with virtual elements reliably, while high precision allows for detailed control, both of which contribute to the overall immersion and realism of the experience.

5 Must Know Facts For Your Next Test
