Abstract: Methods and systems are provided for head mounted display (HMD) implementations. In one example implementation, a HMD includes a circuit for communicating with a computing system that processes multimedia content for display in the HMD. Further included is a front unit of the HMD that has a screen for displaying multimedia content, and the front unit has a set of LEDs. The HMD includes an accelerometer and gyroscope disposed in the front unit of the HMD. A rear section of the HMD is provided having a set of LEDs. A headband connecting the front unit to the rear section is included, such that adjustment of the headband changes a separation distance between at least one of the set of LEDs of the front unit and at least one of the set of LEDs of the rear section.

Abstract: Inertial sensors within a head mounted display are used to track movement of the head mounted display. The tracked movement of the head mounted display is correlated to an action within a virtual reality scene that is currently displayed to a user wearing the head mounted display. The action within the virtual reality scene is based on a context of the virtual reality scene that is currently displayed. The detected movement of the head mounted display can be combined with other sensor data, such as gaze detection data, to determine the action within the virtual reality scene. In this manner, movements of the user as detected using the inertial sensors within the head mounted display are used as inputs to cause actions within the current context of the virtual reality scene as displayed to the user within the head mounted display.

Abstract: Systems and methods include receiving an image for presenting on a display screen of a head mounted display (HMD). The image is provided by an application. The received image is pre-distorted to enable optics provided in a HMD to render the image. An alignment offset is identified for an eye of a user wearing the HMD by determining a position of the eye relative to an optical axis of at least one lens of the optics of the HMD. The pre-distorted image provided by the application is adjusted to define a corrected pre-distorted image that accounts for the alignment offset. The corrected pre-distorted image is forwarded to the display screen of the HMD for rendering, such that the image presented through the optics of the HMD removes aberrations caused by the alignment offset.

Abstract: To calibrate a tracking system, a computing device receives positional data of a tracked object from an optical sensor as the object is pointed approximately toward the optical sensor. The computing device computes a first angle of the object with respect to an optical axis of the optical sensor using the received positional data. The computing device receives inertial data corresponding to the object, wherein a second angle of the object with respect to a plane normal to gravity can be computed from the inertial data. The computing device determines a pitch of the optical sensor using the first angle and the second angle.

Abstract: A number of brightness samples are taken outside a shape to compensate for blooming of the shape in an image generated by a digital camera. The brightness of each of the samples is determined and averaged, and the size of the shape is adjusted based on the difference between the brightness of the shape and the average of the brightness samples.

Abstract: A method for providing directional input to a video game is provided. The method initiates with capturing an image of a first object and a second object, the first object and the second object being defined at a fixed distance from each other. A three-dimensional location of the first object is determined based on analysis of the captured image, and a two-dimensional location of the second object is determined based on analysis of the captured image. An input direction for a video game is determined based on the three-dimensional location of the first object and the two-dimensional location of the second object.

Abstract: Consumer electronic devices have been developed with enormous information processing capabilities, high quality audio and video outputs, large amounts of memory, and may also include wired and/or wireless networking capabilities. Additionally, relatively unsophisticated and inexpensive sensors, such as microphones, video camera, GPS or other position sensors, when coupled with devices having these enhanced capabilities, can be used to detect subtle features about users and their environments. A variety of audio, video, simulation and user interface paradigms have been developed to utilize the enhanced capabilities of these devices. These paradigms can be used separately or together in any combination. One paradigm automatically creating user identities using speaker identification. Another paradigm includes a control button with 3-axis pressure sensitivity for use with game controllers and other input devices.

Abstract: To calibrate an positional sensor, a plurality of image locations and image sizes of a tracked object are received as the tracked object is moved through a rich motion path. Inertial data is received from the tracked object as the tracked object is moved through the rich motion path. Each of the plurality of image locations is converted to a three-dimensional coordinate system of the positional sensor based on the corresponding image sizes and a field of view of the positional sensor. An acceleration of the tracked object is computed in the three-dimensional coordinate system of the positional sensor. The inertial data is reconciled with the computed acceleration, calibrating the positional sensor.

Abstract: Methods and systems for beam forming an audio signal based on a location of an object relative to the listening device, the location being determined from positional data deduced from an optical image including the object. In an embodiment, an object's position is tracked based on video images of the object and the audio signal received from a microphone array located at a fixed position is filtered based on the tracked object position. Beam forming techniques may be applied to emphasize portions of an audio signal associated with sources near the object.

Abstract: An electronic file wrapper contains one or more files that are associated with virtual paths and conditional logic that collectively define a presentation sequence for the one or more files, access control, version control, and enables the reporting of usage metrics that are responsive to a variety of access request parameters. The file wrapper may include one or more of a file wrapper identifier, a version identifier, and an encrypted portion that contains the one or more files in encrypted form. The file wrapper identifier refers to the applicable and appropriate virtual path and conditional logic definitions contained within a database or other suitable information source that is independent of the file wrapper for a given set of access request parameters. The file wrapper may be constructed by an authoring application program or program component, and may be interpreted and presented by a viewer application program or program component.

Abstract: To correct an angle error, acceleration data is received corresponding to a tracked object in a reference frame of the tracked object. Positional data of the tracked object is received from a positional sensor, and positional sensor acceleration data is computed from the received positional data. The acceleration data is transformed into a positional sensor reference frame using a rotation estimate. An amount of error between the transformed acceleration data and the positional sensor acceleration data is determined. The rotation estimate is updated responsive to the determined amount of error.

Abstract: Some embodiments of the invention provide a user interface of editing video through a multi-stage editing process. The user interface selects a particular stage in the editing process. A particular editing operation is performed on a set of video images during the particular stage. After the selection of the particular stage, the user interface uses a background rendering process to render the result of the particular editing operation on the particular set of video images. The background rendering process is a process that the user interface performs separately from the multi-stage video editing process, so that a user may continue editing the video sequence while the rendering occurs. Some embodiments provide a preview of the rendering process in a preview window. Some of these embodiments update the preview in real time. In some embodiments, the rendering occurs to a temporary location and then stores to a persistent storage.
