Abstract
Official abstract text for this publication.
A method for providing audible signals (such as speech) to a driver of a vehicle which appear to originate from a virtual sound source in front of the driver, so that it will feel normal for the driver to respond interactively by speaking without turning the head to the source of the audible signal. The driver's head position is estimated according to data provided by sensors in the driver's seat, and this position data, together with acoustical characteristics of the vehicle interior, is used to derive a transfer function for filtering electrical audible signals to the loudspeakers to simulate a virtual sound source in front of the driver.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for creating a virtual audible source for an audible signal at a virtual source location relative to a driver seated in a seat of a vehicle interior, the vehicle interior having interior acoustical characteristics and at least one loudspeaker having a predetermined loudspeaker location, the method comprising: obtaining seat data from one or more sensors located in the seat; computing an estimated head position of the driver based on the seat data;…
