Locating a head mounted display in a vehicle
A head mounted display is configured to determine the posture of the head mounted display relative to a vehicle. The head mounted display includes a display, a camera and an electronic computing unit; and is set up to: create recordings of the environment of the head mounted display with the aid of the camera; receive details relating to the position and/or orientation of a movable object in the interior of the vehicle; detect the image of the object in the recordings from the camera; and determine the posture of the head mounted display taking into account the image of the object in the recordings relative to the vehicle. The posture of the head mounted display indicates the position of the pair of data glasses and the alignment of the pair of data glasses.
1. A head-mounted display configured to determine a posture of the head-mounted display relative to a vehicle, comprising:
a display;
a camera; and
an electronic computation unit;
wherein the electronic computation unit executes processing to:
take recordings of an environment of the head-mounted display using the camera;
receive statements relating to a position and/or an alignment of a movable object in an interior of the vehicle;
detect an image of the movable object in the recordings of the camera; and
determine the posture of the head-mounted display by taking into consideration the image of the movable object in the recordings relative to the vehicle, wherein the posture of the head-mounted display indicates the position of the head-mounted display and the alignment of the head-mounted display,
wherein the electronic computation unit further executes processing to:
check whether a number of static features sufficient to determine the posture of the head-mounted display is detectable in the recordings of the environment of the camera; and
if an insufficient number of static features are detectable, performing said processing of receiving statements, detecting the image and determining the posture of the head-mounted display taking into consideration the image of the movable object in the recordings relative to the vehicle.
2. The head mounted display according to claim 1 , wherein the electronic computation unit further executes processing to:
receive statements relating to a change rate of the position and/or the alignment of the movable object in the interior of the vehicle.
3. The head mounted display according to claim 1 , wherein the detection of the image of the movable object is carried out in dependence on the received statements related to the position and/or the alignment of the movable object.
4. The head mounted display according to claim 3 , wherein the detection of the image is carried out via pattern recognition, the pattern recognition being adapted to the received statements relating to the position and/or the alignment of the movable object.
5. The head mounted display according to claim 3 , wherein the detection of the image is carried out via a classifier, the classifier being adapted to the received statements relating to the position and/or alignment of the movable object.
6. The head mounted display according to claim 1 , wherein
the movable object is a steering wheel of the vehicle,
the position is a position of the steering wheel, and
the alignment is a steering angle of the steering wheel, wherein the steering angle is a rotational orientation of the steering wheel about a steering wheel axis.
7. The head mounted display according to claim 1 , wherein the determination of the posture of the head-mounted display further takes into consideration one or more non-movable objects in the interior of the vehicle.
8. A method of determining a posture of a head-mounted display in a vehicle, wherein the head-mounted display comprises a display, a camera and an electronic computation unit, the method comprising the acts of:
taking recordings of an environment of the head-mounted display using the camera;
checking whether a number of static features sufficient to determine the posture of the head-mounted display is detectable in the recordings of the environment of the camera;
if an insufficient number of static features are detectable, the method further comprises:
receiving statements relating to a position and/or an alignment of a movable object in an interior of the vehicle;
detecting an image of the movable object in the recordings of the environment taken using the camera and
determining the posture of the head-mounted display by taking into consideration the image of the movable object in the recordings, wherein the posture of the head-mounted display indicates the position of the head-mounted display and the alignment of the head-mounted display.
