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.
