Abstract: Examples of the present disclosure describe systems and methods for controlling video playback speed using user interaction. In aspects, user input may be detected during an aspect of video playback. The user input may correspond to, for example, adding user notes or drawings using one or more input devices (e.g., a stylus, a finger, etc.) to a video being played back. A set of features of the interaction may be determined using one or more sensors. Based on the determined features, a video playback speed may be determined and applied to the video. The video may be played at the determined video playback speed for the duration of the detected user input. When the user input is no longer detected, the video playback may automatically resume at the normal playback speed.

Abstract: The invention relates to a method, comprising: providing orientation measurement data of a gyroscope and accelerometer for a device, performing a sensor fusion algorithm for provided orientation measurement data for determining a sensor-based estimate of orientation of the device, and performing a correction step, wherein an viewfinder image matching algorithm is performed for aligning viewfinder frames captured by a camera sensor of the device for determining an error of sensor-based estimate of orientation of the device. The invention further relates to an apparatus and a computer program product that perform the method.
