Input device and input method, and an electronic apparatus,

The present invention is a mobile phone to be able to continuously acquire the biometric indicator, explicit acquisition operation when used in the user calls, the normal use manner in the operation or the like of the mail input or the like as continuously the biomarkers can be measured position without performing, when the surface on which the display screen provided for displaying the guidance display and information for operation and the housing front side portion of the outer peripheral surface side of the phone or corner, or providing a GSR sensor on the operating surface of the operation input buttons. In a non-foldable mobile phone (1), provided the GSR sensors (50a) on the side surface of the outer peripheral surface of the housing (14), the outer peripheral surface side corner portion (15) to the GSR detection sensor housing ( 50b) providing a. Furthermore, providing a GSR sensor (50c) on the operation surface of the operation input buttons (12). Further comprising a data processing unit for processing the detected value detected by the biological sensor, the detection value judging unit (105), selecting the optimum value from the detected values ​​processed by the data processing unit.
