Problems solved by technology

But larger differences will be perceived by the user and lessen the immersion
This undesirably large rotational deviation of the viewing direction in the rendering of the virtual environment can occur because the sensor device sometimes has measurement errors
Especially when the user utilizes the representation of the virtual environment for a long time, there may be a significant deviation of the viewing direction in the representation of the virtual environment due to the accumulation of erroneous measurements
Therefore, the perceived difference in the viewing orientation in the rendering of the virtual environment may also lead to physical discomfort of the user

Embodiment Construction

[0034] Various embodiments are now described with express reference to the accompanying drawings in which several embodiments are shown. In the drawings, thickness dimensions of lines, layers and / or regions may be exaggerated for clarity.

[0035] In the following description of the figures, which show only a few embodiments, the same reference numerals may designate the same or similar elements. Furthermore, relative reference numerals may be used for elements and objects that appear multiple times in one embodiment or one figure but are commonly described with respect to one or more features. Elements or objects described with the same or related reference numerals may be designed to be identical with respect to individual, multiple or all features, such as their dimensioning, but perhaps also to be different, unless The instructions express or imply otherwise.

[0036] Although the embodiments can be changed and modified in various ways, the embodiments are illustrated by...

Abstract

Provided is a method for setting a viewing direction in a representation of a virtual environment. The method includes recording a known object in a real environment with a recording device. The method further includes a determination of a rotational offset of the viewing direction in the representation of the virtual environment about a yaw axis of the representation of the virtual environment, based upon the recording of the object, a known position of the recording device in the real environment and a current viewing direction in the representation of the virtual environment. The method further includes a turning of the viewing direction in the representation of the virtual environment by the amount of the rotational offset.

Description

technical field [0001] Embodiments relate to the presentation of virtual environments. In particular, embodiments relate to methods for adjusting the viewing direction in the rendering of a virtual environment. Background technique [0002] Virtual reality (VR) refers to the computer-generated presentation and simultaneous perception of an interactive virtual environment and its physical characteristics. In order to create the feeling of being immersed in it, presenting the virtual environment to the user may be implemented, for example, through a display device fixed on the user's head. Such devices are known as head mounted displays (HMDs), head mounted display units or head mounted units (HMUs). The display device presents the virtual environment on, for example, a screen in front of the user's eyes, or directly projects it onto the user's retina. The orientation (i.e. the viewing direction) in the rendering of the virtual environment is then rotated around the horizon...
