Virtual display device for a vehicle instrument panel
First Claim
1. A display arrangement for a vehicle instrument panel which can be controlled by a vehicle user, wherein it comprises:
- a support structure wearable by the user, on which is disposed at least one transparent screen element which can be positioned in front of at least one of the user'"'"'s eyes in such a way as to permit the user to see at least part of the background through this screen;
virtual image generator means disposed on the said support structure, operable to generate a virtual image variable in time and to present it to the user'"'"'s eyes through the transparent screen at a predetermined distance, the said virtual image being superimposed on the scene visible by the user through the transparent screen;
means for detecting the position and orientation of the user'"'"'s head, at least partly disposed on the said support structure; and
a processor unit operatively connected to a plurality of vehicle control systems, operable to provide to the said virtual image generator means a video signal containing information to deliver to the user on the basis of system signals provided by the said plurality of control systems in such a way that the said virtual image generator generates a corresponding virtual visual information superimposed over the background in predetermined regions of the field of view, the said visual information being rendered stationary with respect to a frame of reference predetermined on the basis of a detection signal from the said means for detection of the position and orientation of the user'"'"'s head.

Abstract
A display arrangement for a vehicle instrument panel comprises a wearable support structure on which is disposed a transparent screen positioned in front of an eye of an user to permit part of the background to be seen through this screen; a virtual image generator disposed on the support to generate a virtual image and present it to the user'"'"'s eyes at a predetermined distance and superimposed over the scene visible through the transparent screen; a device for detecting the position and orientation of the user'"'"'s head; and a processor connected to vehicle control systems to provide the virtual image generator with a video signal containing information to deliver to the user on the basis of system signals provided by the control systems in such a way that the virtual image generator generates virtual visual information superimposed over the background in predetermined regions of the field of view. The visual information is fixedly located in relation to a frame of reference on the basis of a signal provided by the detection device.
