Abstract: An apparatus and method for position determination in a 3D model of an environment and a computer-executed iterative method for position determination in a 3D model of an environment. The method includes the steps of: a) acquisition of camera, gyroscope and accelerometer data, b) determination of visual features from the acquired camera sensor data, c) creation of a current key image of the pose (PK) from the visual features and the gyroscope and accelerometer sensor data, d) addition of the key image of the pose (PK) to a database, and e) position determination by comparing the current key image of the posture (PK) with those of the database.

Abstract: A computer-implemented method for simultaneously recording a media recording and an event recording includes recording a media recording, recording an event recording simultaneously with the media recording, the event recording encoding a plurality of events, an event being related to one or more user interactions with an input device associated with the media recording and recording the event recording includes for each of a plurality of events of the event recording generating data characterizing the particular event and generating a corresponding time stamp for the particular event by polling a system time of a computer device at the time the particular event takes place, the method further includes providing the data characterizing the particular event and the corresponding time stamp for storage.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for obtaining first position information of a first user interaction with a multimedia content item that is presented at a first time to the first user in a presentation area on a first computer device; obtaining, in response to obtaining the first position information, second position information of a second user interaction with the multimedia content item that was presented at a second time to a second user in a presentation area on a second computer device, the second time occurring before the first time; calculating a correlation score that is indicative of the relatedness of the second user interaction to the first user interaction; and in response to the correlation score meeting a threshold value, providing a first data set provided by the second user and associated with the first user interaction to the first user.
