Abstract: An information displaying device has a virtual hand generating portion that generates a virtual hand that displays an image of a hand of a user. The virtual hand generating portion includes a transformation ratio calculating portion that calculates a display scale for an object in a display screen, based on the spacing between objects and/or the sizes of objects included in the display data, and calculates a virtual hand transformation ratio from the display scale and the finger widths of the virtual hand. The virtual hand generating portion also includes a virtual hand transforming portion that transforms the virtual hand to a size suited to the objects in the screen display through enlarging or reducing the virtual hand based on the transformation ratio.

Abstract: A case base generator divides an input space of history data into unit input spaces according to a desired output allowable error, and creates a representative case from the history data arranged in the unit input spaces, thereby generating a case base. A case retrieving section of a soft sensor retrieves a case corresponding to new input data from the case base. An output estimating section calculates and outputs estimated output data corresponding to the new input data on the basis of the output data on the retrieved case. An output evaluating section calculates and outputs an estimation error in the estimated output data on the basis of the topological distance between the new input data and the retrieved case. A function evaluating section evaluates the soft sensor on the basis of the estimation error, the estimated output data, and true output data.
