Abstract: A game-agnostic event detector can be used to automatically identify game events. Game-specific configuration data can be used to specify types of pre-processing to be performed on media for a game session, as well as types of detectors to be used to detect events for the game. Event data for detected events can be written to an event log in a form that is both human- and process-readable. The event data can be used for various purposes, such as to generate highlight videos or provide player performance feedback.

Abstract: A method for tracking device orientation on a portable device is disclosed. The method comprises initializing a device orientation to a sensor orientation, wherein the sensor orientation is based on information from an inertial measurement unit (IMU) sensor. It also comprises initiating visual tracking using a camera on the portable device and capturing a frame. Next, it comprises determining a plurality of visual features in the frame and matching the frame to a keyframe, wherein capture of the keyframe precedes capture of the frame. Subsequently, it comprises computing a rotation amount between the frame and the keyframe. Responsive to a determination that a rotational distance between the frame and the keyframe exceeds a predetermined threshold, promoting the frame to a keyframe status and adding it to a first orientation map and adjusting the frame with all prior captured keyframes.
Abstract translation: 公开了一种在便携式设备上跟踪设备取向的方法。 该方法包括将装置取向初始化为传感器取向，其中传感器取向基于来自惯性测量单元（IMU）传感器的信息。 它还包括使用便携式设备上的相机启动视觉跟踪并捕获帧。 接下来，它包括确定帧中的多个视觉特征并将帧与关键帧匹配，其中关键帧的捕获先于帧的捕获。 随后，它包括计算帧和关键帧之间的旋转量。 响应于确定帧和关键帧之间的旋转距离超过预定阈值，将帧推广到关键帧状态并将其添加到第一方向图并且利用所有先前捕获的关键帧来调整帧。

Abstract: Apparatuses, systems, and techniques to determine position information for a gameplay session. In at least one embodiment, the position information is determined by at least matching features extracted from a mini-map to feature extracted from a map and determining a transformation matrix to be applied to a position within the mini-map.

Abstract: A game-agnostic event detector can be used to automatically identify game events. Event data for detected events can be written to an event log in a form that is both human- and process-readable. Descriptive text for the event data can come from a common event dictionary that is hierarchical in nature, such that events of the same type can be correlated across different games even though the precise nature or appearance of those events may be different. The event data can be used for various purposes, such as to generate highlight videos or provide player performance feedback.
