Abstract: A tactile reproduction system achieves a data amount reduction of a tactile signal while ensuring reproducibility of a tactile sense. A decoding apparatus includes a decoding unit configured to decode tactile coded data obtained by performing encoding of compressing an information amount, on a tactile signal using higher-order perception in a tactile sense. Therefore, a data amount reduction of a tactile signal can be performed in accordance with a tactile characteristic of a human.

Abstract: To achieve simplification in configuration and reduction in cost of a tactile reproduction system that reproduces tactile information. The signal generation device according to the present technology includes a signal generation unit that generates a tactile signal on the basis of a detection value of a motion detection unit that is provided in an imaging device and detects motion of the imaging device. This eliminates the need to provide a separate motion detection unit other than the motion detection unit provided in the imaging device in order to realize a system that reproduces tactile information together with visual information.

Abstract: A system related to tactile reproduction is made more efficient by achieving a data amount reduction of a tactile signal while ensuring reproducibility of a tactile sense. An encoding apparatus includes an encoding unit configured to encode tactile signals using different data formats between different regions of a human body. Therefore, for example, a data amount reduction of a tactile signal can be performed considering difficulty in perceiving tactile stimulation of a region, by reducing a data distribution of a tactile signal for a region with low tactile sensitivity using a difference in tactile sensitivity between regions of a human body, and the like.

Abstract: To reduce data amount while ensuring tactile reproducibility of a two-dimensional tactile signal, and improve the efficiency of a system related to tactile reproduction.
Coding is performed to compress information amount by orthogonally transforming a two-dimensional tactile signal based on a time signal. By orthogonally transforming a two-dimensional tactile signal based on a time signal, it is possible to compress information amount by removing frequency components that are difficult for humans to perceive, as in the case of an image signal, for example. Accordingly, it is possible to reduce data amount while ensuring tactile reproducibility of a two-dimensional tactile signal, and improve the efficiency of a system related to tactile reproduction.
