Abstract: An apparatus and method of generating personalized HRTFs. The system is prepared by calculating a model for HRTFs described as the relationship between a finite example set of input data, namely anthropometric measures and demographic information for a set of individuals, and a corresponding set of output data, namely HRTFs numerically simulated using a high-resolution database of 3D scans of the same set of individuals. At the time of use, the system queries the user for their demographic information, and then from a series of images of the user, the system detects and measures various anthropometric characteristics. The system then applies the prepared model to the anthropometric and demographic data as part of generating a personalized HRTF. In this manner, the personalized HRTF can be generated with more convenience than by performing a high-resolution scan or an acoustic measurement of the user, and with less computational complexity than by numerically simulating their HRTF.

Abstract: A method comprising acquiring a set of voltage signals from a set of electrodes arranged in proximity to the ears of a user, based on the set of voltage signals, determining an EOG gaze vector in ego-centric coordinates, determining a head pose of the user in display coordinates, using a sensor device worn by the user, combining the EOG gaze vector and head pose to obtain a gaze vector in display coordinates, and determining a gaze point by calculating an intersection of the gaze vector and an imaging surface having a known position in display coordinates.

Abstract: Encoding/decoding techniques where multiple transform parameter sets are encoded together with a rendered playback presentation of an input audio content. The multiple transform parameters are used on the decoder side to transform the playback presentation to provide a personalized binaural playback presentation optimized for an individual listener with respect to their hearing profile. This may be achieved by selection or combination of the data present in the metadata streams.
