Adapting a warning output based on a driver's view
First Claim
1. An apparatus comprising processing circuitry configured to:
- determine which of a plurality of visual warning devices is within a first determined viewing angle of a driver; and
signal a first visual warning device, from among the plurality of visual warning devices, to output a first visual warning when the first visual warning device is determined to be within the first determined viewing angle of the driver.

Abstract
A human machine interface (HMI) can communicate warnings and messages to a driver by selecting among a variety of warning devices based on information related to the driver'"'"'s viewing angle. The variety of warning devices can include a primary-visual warning device (e.g., a heads up display), secondary-visual warning devices (e.g., an instrument cluster or a navigational screen), a portable device (e.g., a tablet or a cellular phone), an audio system, or a haptic device. The HMI apparatus displays warnings on visual warning devices within the driver'"'"'s view, can signal an active portable device to output a warning. Visual warnings can include directional cues. Audio warnings may accompany the visual warnings, and can be output with greater intensity when no visual devices are within the driver'"'"'s view.

18. A method comprising:
-
determining which of a plurality of visual warning devices is within a determined viewing angle of a driver; signaling a first visual warning device, from among the plurality of visual warning devices, to output a first visual warning when the first visual warning device is determined to be within the determined viewing angle of the driver; determining which, if any, of the plurality of visual warning devices are within view of the driver; signaling a non-visual warning device to output a first non-visual warning at a first warning level when none of the plurality of visual warning devices are determined to be within the determined viewing angle of the driver; signaling a portable device to output a portable-device warning when a state of the portable device is determined to be active; monitoring a response of the driver to the first visual warning, the first non-visual warning, and the portable-device warning; and augmenting one or more of the first visual warning, the first non-visual warning, and the portable-device warning when the response of the driver does not satisfy a predetermined criterion. - View Dependent Claims (19)

20. A system comprising:
-
a driver-monitor device configured to detect a viewing angle of a driver; a plurality of warning devices, including a plurality of visual warning devices and at least one non-visual warning device; control circuitry configured to; determine which of the plurality of visual warning devices is within the viewing angle of a driver; signal a first visual warning device, from among the plurality of visual warning devices, to output a first visual warning when the first visual warning device is determined to be within the determined viewing angle of the driver; signal the non-visual warning device to output a first non-visual warning when no visual warning device is determined to be within the determined viewing angle of the driver; determine whether the driver is responsive to the first visual warning or the first non-visual warning; and signal a portable device to output a portable-device warning when the driver is determined to not be responsive to the first visual warning or the first non-visual warning.
