NON-VISUAL NAVIGATION FEEDBACK SYSTEM AND METHOD

摘要

A system for generating a non-visual notification of a machine condition includes a machine condition sensor configured to sense a machine condition. A notification generation controller is in communication with the machine condition sensor. The notification generation controller generates a notification according to the sensed machine condition. In a feedback configuration the notification generation controller compares an integral of a rate of change of the sensed machine condition with a threshold to trigger the generation of a notification. In a guidance configuration the notification generation controller uses the deviation of the machine condition from a guidance direction determined with a steering algorithm to control the generation of a notification. A non-visual notification generator is in communication with the notification generation controller and generates a non-visual notification based on the notification.

1. A method for non-visually indicating a change in a machine condition comprising:
changing a machine condition; generating a non-visual increment notification of change of the machine condition based on a rate of change of the machine condition, generating the non-visual increment notification including:
sensing the rate of change of the machine condition,integrating the sensed rate of change of the machine condition to determine an instantaneous integral of the rate of change,comparing the instantaneous integral of the rate of change with a threshold, andgenerating the non-visual increment notification based on the comparison; and changing the instantaneous integral of the rate of change based on the generation of the non-visual increment notification.
