More Information
Summary:Motion sickness resulting from use of a virtual reality headset can be mitigated by displaying a virtual nose in the field of view of the user. Nose data can be obtained by a user selecting various options, or determined dynamically using various image analysis algorithms. Image data captured of the user's face can be data analyzed to determine aspects such as the size, shape, color, texture, and reflectivity of the user's nose. A three-dimensional nose model is generated, which is treated as an object in the virtual world and can have lighting, shadows, and textures applied accordingly. The pupillary distance can be determined from the image data and used to determine the point of view from which to render each nose portion. Changes in lighting or expression can cause the appearance of the nose to change, as well as the level of detail of the rendering.
