Abstract
Although it has been demonstrated that cutaneous informational displays can be used effectively in certain types of systems, little is known of the characteristics of such displays that may affect performance. The present investigation was designed to determine which of three degrees of preciseness of electrocutaneous feedback information results in the most accurate tracking performance for each of two levels of task difficulty. Contrary to expectations, the most precise (continuous) error information did not result in the best performance. On both levels of task difficulty, the best performance resulted when error information of an intermediate precision was used.
