Abstract: A virtual reality (VR) or augmented reality (AR) head mounted display (HMD) includes multiple image capture devices positioned within the HMD to capture portions of a face of a user wearing the HMD. Images from an image capture device include a user's eye, while additional images from another image capture device include the user's other eye.

Abstract: An interactive system may include (1) a facial coupling subsystem configured to conduct a biopotential signal generated by a user's body, (2) a receiving subsystem electrically connected to the facial coupling subsystem and configured to receive, from the user's body via a compliant electrode of the facial coupling subsystem, the biopotential signal, and (3) a detection subsystem electrically connected to the receiving subsystem and configured to (a) determine a characteristic of the biopotential signal and (b) use the characteristic of the biopotential signal to determine a gaze direction of an eye of the user and/or a facial gesture of the user. In some examples, the facial coupling subsystem may include a plurality of compliant electrodes that each are configured to comply in a direction normal to a surface of the user's face.

Abstract: A virtual reality (VR) or augmented reality (AR) head mounted display (HMD) includes various facial sensors, such as cameras, that capture images of portions of the user's face outside of the HMD. For example, multiple facial sensors capture images of a portion of the user's face below the HMD. Through image analysis, points of the portion of the user's face are identified from the images and their movement is tracked. The identified points are mapped to a three dimensional model of a face. Additionally, a parametric representation of the user's face is determined for each captured image, resulting in various representations indicating the user's facial expressions. From the parametric representations and transforms mapping the captured images to three dimensions, a rendering model is used and applied to the three dimensional model of the face to render the user's facial expressions.

Abstract: A virtual reality (VR) or augmented reality (AR) head mounted display (HMD) includes various image capture devices that capture images of portions of the user's face and body. Through image analysis, points of each portion of the user's face and body are identified from the images and their movement is tracked. The identified points are mapped to a three dimensional model of a face and to a three dimensional model of a body. From the identified points, animation parameters describing positioning of various points of the user's face and body are determined for each captured image. From the animation parameters and transforms mapping the captured images to three dimensions, the three dimensional model of the face and the three dimensional model of the body is altered to render movement of the user's face and body.

Through image analysis, points of each portion of the user's face are identified from the images and their movement is tracked. The identified points are mapped to a three dimensional model of a face. From the identified points, a blendshape vector is determined for each captured image, resulting in various vectors indicating the user's facial expressions. A direct expression model that directly maps images to blendshape coefficients for a set of facial expressions based on captured information from a set of users may augment the blendshape vector in various embodiments. From the blendshape vectors and transforms mapping the captured images to three dimensions, the three dimensional model of the face is altered to render the user's facial expressions.

Abstract: The invention relates to a method for detecting objects on a pixel plane. Said movable object detection is frequently possible only by tracking the pre-segmented objects or the parts thereof. in this relation, the spatially adjacent objects often provoke problems, in particular in the case when a camera system or more precisely an observer is movable. The inventive method consists in determining a two-dimensional position of the relevant pixels inside a first image and in determining an associated remote value for each relevant pixel. Said pixels are tracked and localized on two ore more successive images, wherein the two-dimensional position or the pixel offset and the associated remote value are again determined for each pixel. The position and movement of the relevant pixels are also determined with the aid of a suitable filter. Finally, the relevant pixels are combined into objects under predefined conditions with respect to the position, moving direction and motion ratio thereof.
