A detection-rate calculating unit calculates a detection rate representing a ratio of number of interval data representing a time interval of one cycle of a waveform of at least one of a pulse and a heart rate, generated within a predetermined reference time to a sum of the number of the interval data and number of error data representing a content of an error occurred while the interval data is generated. When the detection rate is larger than the first threshold, an index calculating unit calculates an autonomic-nervous index representing an autonomic-nervous activity state, based on the interval data generated within the reference time.

A display input device comprises a display unit having a flexibility; and a first form change detection unit having a flexibility. The first form change detection unit is able to detect a deformation ascribed to the flexibility as a change in a electrical property. A display input system further comprises a display driving unit that supplies a display signal to the display unit and a signal judging unit that judges a input data based on the change in a electrical property in the first form change detection unit. The input of a first data can be performed by adding the deformation to the display input device.
