The number of haptic algorithms has been growing over the past few years. However, little research has been performed in evaluating these algorithms. This paper provides both a theoretical framework and a practical discussion of how the correctness and performance of force-feedback algorithms can be verified. The practical discussion is necessary as the theoretical framework proves that an infinite number of cases should be considered when evaluating a haptic algorithm. However, using statistical techniques, this evaluation can be performed within a reasonable frame of time. The evaluation method in this paper has itself been validated by evaluating two algorithms. From this test, we can conclude that the evaluation method is a reliable method for verifying if haptic algorithms are correct.
