Title: Method for tracking orientation of an object, tracker system and head or helmet-mounted display
Inventor: Simon Trythall
IPC: G06F3/01
Filed: 2021-09-08
Abstract: A method of finding the intended orientation of an augmented reality user’s head when subjected to vibrations or buffeting in a vehicle by: determining the force 210 at the point of contact (110 fig. 1), which may be a seat; using an adaptive filter 230 with a filter coefficient, such as a recursive least squares filter, to predict an involuntary change due to the force of the orientation of the user’s head at a certain time; determining, using a head tracking system 220 or maybe a predictive head tracker (330, figs 3 and 4), the orientation of the user’s head at that time; and subtracting 240 the predicted value from the orientation, to update the filter coefficient. Band-pass filters may be applied to the measured head orientation signals and to the force signals, which may be: position or velocity; rotary or linear; and from which the orientation may be predicted by a time delay. An output indicating the intended orientation may be derived from the force signal using a second filter (320, figure 3) such as a finite impulse response filter, using the same filter coefficient.

IPC: G11B27/031
Filed: 2021-10-25
Abstract: Acquiring a multimedia file and an operation information contained in each editing Track. Operation information is acquired to edit the multimedia file, a multimedia file frame contained in the each editing track at a current time detected in a case of editing the multimedia file in a chronological order, so as to obtain an edited file frame contained in the each editing track at the current time; and performing an encoding synthesis on the edited file frame contained in the each editing track at the current time. By performing the encoding synthesis on the multimedia file frames contained in different editing tracks at the current time, a granularity of the encoding synthesis may be reduced to a granularity of frame, which facilitates control of the encoding synthesis. This allows video, mapping, subtitle and audio tracks for example to be superimposed in an edited file frame, with an encoding synthesis progress according to the playback time, and reduce errors in FFmpeg bulky transcoding. A calculation of an audio waveform may be done, in audio mixing. Other operations may be filters, special effects, transition, multiple speed information, clipping, rotation, image brightness, chroma, saturation, size, duration or display coordinates.
