The number n of times of chewing is counted by chewing number of times calculation means () based on a change in the distance l from a photoreflector (), which is received together with time t by measurement value receiving means (). To vary hardness h of a bag () to a stage that can be sensed, according to the number n of times of chewing, a required air pressure is set according to the current number n of times, based on a hardness/air pressure correspondence recording unit () in which stages that have a significant difference therebetween and are stored in association with the number n of times of chewing are recorded. To realize the set air pressure inside the bag (), the amount of sucking performed using a vacuum pumpis controlled by air pressure control means ().

An embodiment of the present invention is provided with a projective transform model including a plurality of nodes and a projection table, the plurality of nodes each holding a reference vector having a dimension corresponding to the dimension of multi-dimensional data. The projection table indicates the correspondence relation between the number of each node and a coordinate in a two-dimensional space as a projection target of the reference vector held by the node. First in a learning phase, multi-dimensional input data of a positive example and a negative example is acquired, the amplitude characteristic amounts thereof are calculated, and this amplitude characteristic amount data is learned as the reference vectors of the nodes for each sample. Subsequently, the Euclidean distance between coordinates when the nodes learned based on the amplitude characteristic amount data of the positive example and the nodes learned based on the amplitude characteristic amount data of the negative example are projected into the two-dimensional space in accordance with the projection table is calculated, and coordinates in the projection table are updated so that the calculated Euclidean distance becomes equal to or larger than a threshold value.

To reduce a burden on a user in editing tree structure data with a text editor. When a selection range is designated on an edit screen, a node selection unit of a tree structure data editing device selects one or more node IDs in the tree structure data, based on the position of the selection range. When a paste target for the selection range is designated on the edit screen, a connection target determination unit determines a connection target node ID in the tree structure data, based on the position of the paste target. A tree structure data editing unit edits the tree structure data such that the node or nodes identified by the one or more node IDs is/are connected to the node identified by the connection target node ID. A conversion unit convers the tree structure data edited by the tree structure data editing unit into text data. A display control unit updates the edit screen displayed, based on the text data converted by the conversion unit.

The present invention aims to provide a more generally applicable programming environment for visual programming languages than conventional programming environments and to reduce data size of programs. With programming language data (a text VPL), which is a text based programming language data combining functions and connection characters composed of character data and defines relationships between the functions based on positional relations of the functions with reference to the connection characters in a display space of a text editor, the functions and the connection characters in character strings of the programming language data are distinguished and relationships between the functions are interpreted based on the positional relations in the display space. Interpretation of the text VPL enables a computer device to perform processing according to the text VPL, consequently realizing a generally applicable programming environment and reducing program data size.
