Human-machine interface (HMI) auto-steer based upon-likelihood to exceed eye glance guidelines
First Claim
1. A method for presenting a display screen for a graphical human machine interface (HMI) for a moving vehicle based on likelihood to exceed eye glance guidelines, wherein the graphical HMI is configured, for a task requiring a user to view the graphical HMI, with a conventional HMI screen and an alternative HMI screen, the method comprising:
- receiving a user input corresponding to the task requiring the user to view the graphical HMI;
determining a user action required for the task,determining a time value associated with performing the user action required for the task, the time value being taken from the group consisting of;
an associated average standard glance time (ASGT) value, andan associated eyes off the road time (EORT) value;
determining whether the task would violate an eye glance guideline for the moving vehicle by comparing an eye glance guideline time value to the time value associated with performing the user action; and
conditionally presenting only one of the conventional and the alternative HMI screens by presenting the conventional HMI screen only if the task would not violate the eye glance guideline and otherwise presenting the alternative HMI screen.

Abstract
The described method and system provide for HMI steering for a telematics-equipped vehicle based on likelihood to exceed eye glance guidelines. By determining whether a task is likely to cause the user to exceed eye glance guidelines, alternative HMI processes may be presented to a user to reduce ASGT and EORT and increase compliance with eye glance guidelines. By allowing a user to navigate through long lists of items through vocal input, T9 text input, or heuristic processing rather than through conventional presentation of the full list, a user is much more likely to comply with the eye glance guidelines. This invention is particularly useful in contexts where users may be searching for one item out of a plurality of potential items, for example, within the context of hands-free calling contacts, playing back audio files, or finding points of interest during GPS navigation.

10. A tangible, non-transient computer-readable medium, part of a telematics unit on a telematics-equipped vehicle, having thereon computer executable instructions for presenting a display screen for a graphical human machine interface (HMI) based on likelihood to exceed eye glance guidelines, wherein the HMI is configured, for a task requiring a user to view the graphical HMI, with a conventional HMI screen and an alternative HMI screen, the computer executable instructions comprising instructions for:
-
receiving a user input corresponding to the task requiring the user to view the graphical HMI; determining a user action involved in the task, determining a time value associated with performing the user action required for the task, the time value being taken from the group consisting of; an associated average standard glance time (ASGT) value, and an associated eyes off the road time (EORT) value; determining whether the task would violate an eye glance guideline for the moving vehicle by comparing an eye glance guideline time value to the time value associated with performing the user action; and conditionally presenting only one of the conventional and the alternative HMI screens by presenting the conventional HMI screen only if the task would not violate the eye glance guideline and otherwise presenting the alternative HMI screen. - View Dependent Claims (11, 12, 13, 14, 15, 16)
