Claim Text:
1. An encoder for encoding data defining coded orientations representing a reorientation of an object based on spatio-temporal data representing a time series of orientations of the object, the encoder comprising: a deriver configured to derive a plurality of components describing an orientation change difference between a last coded orientation change from a second last coded orientation to a last coded orientation, and a current orientation change from the last coded orientation to a current orientation of the object; a selector configured to select a component of the plurality of components describing the orientation change difference; and a coder configured to code the current orientation of the object by coding the selected component of the plurality of components describing the orientation change difference, thereby defining a current coded orientation, wherein the coder is configured to not code another component or components of the plurality of components describing the orientation change difference; wherein the time series of orientations of the object is detected by an orientation sensor; the deriver is configured to derive the plurality of components describing the orientation change difference such that the plurality of components correspond to angular components of an angular coordinate system; the deriver is configured to derive the plurality of components describing the orientation change difference such that the plurality of components correspond to Euler angles of a reference system; and each of the deriver, the selector, and the coder is implemented using an integrated circuit, a field programmable gate array, or a digital signal processor, or a combination of at least two of the integrated circuit, the field programmable gate array, and the digital signal processor.
