Efficient orientation estimation system using magnetic, angular rate, and gravity sensors

A system that efficiently estimates an object's orientation using magnetic, angular rate, and gravity sensors. The object may be for example a virtual reality headset or a user in a virtual reality environment. Magnetic and gravity data are used to correct errors that accumulate from integrating angular velocity. Unlike systems that use Kalman filter approaches, embodiments of the system apply a simple, highly efficient technique to generate magnetic and gravity error vectors; these error vectors are added directly to the angular velocity prior to integration. Error calculations are performed in the sensor reference frame rather than in the Earth reference frame. Magnetic error correction uses only the horizontal component of the magnetic field, which is efficiently calculated by subtracting off the projection of the magnetic field onto the measured gravity vector. Sensors and processors for calculating orientation may be integrated into a low-latency virtual reality display system.

Variable resolution virtual reality display system

A virtual reality display system that renders images at different resolutions in different parts of a display. Reduces rendering latency by rendering at a lower resolution in selected regions, for example on the sides of a display where human vision has lower resolution than in the center. Pixels in low resolution regions are combined into grid elements, and rendering may generate grid element values rather than individual pixel values. Rendering may use ray casting, rasterization, or both. Variable resolution rendering may be combined with variable level of detail geometry models to further reduce rendering time. Selected objects may be designed as high resolution objects that are rendered at a high resolution even in low resolution display regions.

Peripheral field-of-view illumination system for a head mounted display

A display system for a head mounted device that illuminates the peripheral regions of the user's field of view to enhance an immersive experience.

Peripheral light emitters may provide lower resolution images, or only with vertical resolution, corresponding to the user's lower resolution vision in these peripheral regions. Reflective surfaces and lenses may be used to direct peripheral light into desired shapes and patterns. Rendering of peripheral light colors and intensities at each peripheral pixel may use approximations for improved performance since users may not be sensitive to precise color values in the peripheral regions.

Virtual reality system with control command gestures

On the other hand, responsive to a determination that the information from the first sensor satisfies the first alert threshold and that the information from the second sensor satisfies the second alert threshold, the alert signal is generated for output thereof to a display device.

Virtual reality headset with relative motion head tracker

A virtual reality headset that tracks motion of a user relative to a moving vehicle in which the user is located. The system updates the headset's display based on relative motion, rather than on absolute motion due to vehicle movement. Data from sensors on the headset, the vehicle, or both is analyzed to determine the pose (orientation, position, or both) of the headset relative to the vehicle. Sensors may include headset-mounted cameras that observe the vehicle's interior from the user's viewpoint. Analysis of camera images may use optical flow or it may compare images to reference images captured from known poses. The system may also combine data from headset sensors and vehicle sensors to calculate the relative pose. Headset-mounted cameras may function both as relative pose sensors for virtual reality, and as image capture devices for display of the real environment on the headset.

Wide field-of-view head mounted display system

A display system for a head mounted device that provides a wide field-of-view image to the user. The system may use a pair of displays angled relative to one another, and a lens or lenses between the displays and the user's eyes to generate a wide field-of-view image. Lenses may be for example gradient index lenses, Fresnel lenses, or holographic optical elements in order to provide significant and complex bending of light across the field of view with relatively thin lenses. The system may provide lower resolution images at the periphery of the user's field of view, using for example light emitting elements at the periphery that are directed by the lens or lenses towards the outside edges of the field of view.

Dynamic bit rate control process

A process of bit rate control includes asymmetrical reactions to changes in the signal density of the digital video signals. In the process, two different averaging periods are employed to meet a long term bit rate target and to achieve a short term quick reaction. When encoding a motion picture, the bit rate control is relaxed during high motion scenes to allow high peaks of bit rate at those points. The coding process reacts slowly to transitions from low to high motion sequences to preserve the best overall video quality, and reacts quickly to transitions from high to low motion sequences to enhance the image quality.

Low-latency virtual reality display system

A low-latency virtual reality display system that provides rapid updates to virtual reality displays in response to a user's movements. Display images generated by rendering a 3D virtual world are modified using an image warping approximation, which allows updates to be calculated and displayed quickly. Image warping is performed using various rerendering approximations that use simplified 3D models and simplified 3D to 2D projections. An example of such a rerendering approximation is a shifting of all pixels in the display by a pixel translation vector that is calculated based on the user's movements; pixel translation may be done very quickly, possibly using hardware acceleration, and may be sufficiently realistic particularly for small changes in a user's position and orientation. Additional features include techniques to fill holes in displays generated by image warping, synchronizing full rendering with approximate rerendering, and using prediction of a user's future movements to reduce apparent latency.

Reflective surfaces and lenses may be used to direct peripheral light into desired shapes and patterns. Rendering of peripheral light colors and intensities at each peripheral pixel may use approximations for improved performance since users may not be sensitive to precise color values in the peripheral regions.

Neural Network Activation Scaled Clipping Layer

Activation scaled clipping layers for neural networks are described. An activation scaled clipping layer processes an output of a neuron in a neural network using a scaling parameter and a clipping parameter. The scaling parameter defines how numerical values are amplified relative to zero. The clipping parameter specifies a numerical threshold that causes the neuron output to be expressed as a value defined by the numerical threshold if the neuron output satisfies the numerical threshold. In some implementations, the scaling parameter is linear and treats numbers within a numerical range as being equivalent, such that any number in the range is scaled by a defined magnitude, regardless of value. Alternatively, the scaling parameter is nonlinear, which causes the activation scaled clipping layer to amplify numbers within a range by different magnitudes. Each scaling and clipping parameter is learnable during training of a machine learning model implementing the neural network.

Optimizing low precision and sparsity inference without retraining

An apparatus and method for efficiently creating less computationally intensive nodes for a neural network. In various implementations, a computing system includes a processor and a memory with circuitry that stores multiple input data values to process during inference of a trained neural network. The processor determines, during inference, which node input values, node intermediate values, and node output values of the trained neural network to represent in a respective one of multiple available floating-point formats with less precision. No retraining is performed, but rather, the updates to the representations occur during inference. The processor uses selection criteria to reduce the amount of computation involved for updating the representations during inference while maintaining accuracy above an accuracy threshold. To do so, the processor uses the selection criteria to reduce the number of layers, the number of nodes within a layer, and the number of weight values per node to inspect.
