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. The images and the additional images are provided to a controller, which applies a trained model to the images and the additional images to generate a vector identifying a position of the user's head and positions of the user's eye and fixation of each of the user's eyes. Additionally, illumination sources illuminating portions of the user's face include in the images and in the additional images are configured when the user wears the HMD to prevent over-saturation or under-saturation of the images and the additional images.

Determining fixation of a user's eyes from images of portions of the user's face enclosed by a head mounted display

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. Various other apparatus, systems, and methods are also disclosed.

Apparatus, systems, and methods for sensing biopotential signals via compliant electrodes

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.

Generating a graphical representation of a face of a user wearing a head mounted display

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.

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. 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.

A virtual reality (VR) or augmented reality (AR) head mounted display (HMD) includes multiple image capture devices positioned within and on the HMD to capture portions of a face of a user wearing the HMD. Multiple image capture devices are included within the HMD to capture different portions of the face of the user within the HMD, and one or more other image capture devices are positioned to capture portions of the face of the user external to the HMD. Captured images from various image capture devices may be communicated to a console or a controller that generates a graphical representation of the user's face based on the captured images.

A system is provided that can include a 3D sensor. The 3D sensor can be configured to detect an area of an elevator on a harvester. The 3D sensor can further be configured to transmit a first signal associated with the area. The system can also include a processing device in communication with the 3D sensor. The system can further include a memory device in which instructions executable by the processing device are stored for causing the processing device to receive the first signal and determine a volume of a material on the elevator based on the first signal.
