Abstract: Methods and apparatus of encoding/decoding haptic signal representative of haptic effect. The haptic signal is encoded according to a hierarchical representation, which includes a plurality of layers, a different hierarchical level being associated with each layer. The encoding of the haptic signal comprises the encoding, in the first layer, of a first set of base signals, which includes one or more base signals. First data representative of each base signal of the first set is encoded in this first layer, each base signal being represented in a determined space. Second data is encoded in the first layer in addition to the first data, the second data being representative of modulation of each base signal. Third data representative of the determined space is then encoded in a layer, different from the first layer, having a hierarchical level higher than a hierarchical level of the first layer.

Abstract: Methods and apparatus of signaling/parsing data representative of a mapping between a body part of a body model targeted by a haptic effect and a haptic device comprising a set of haptic actuators the configured to render the haptic effect on at least a part of the body part are disclosed. The signaling/parsing of the data comprises writing/reading, into/from a container, first data representative of the body part and second data representative of a spatial distribution of the set of haptic actuators in a determined multidimensional space.
