1. A mobile apparatus comprising:

  • a main body;

    a touch screen disposed on a front surface of the main body and configured to display at least one operation switch at a display position for receiving an input signal from at least one digit of a hand of a user holding the mobile apparatus, wherein the at least one digit is a thumb of the hand; and

    a biosensor disposed on a top side surface of the main body that is above the front surface and extends in a direction orthogonal to the front surface, the biosensor being configured to detect a biosignal from another digit of the hand of the user holding the mobile apparatus, other than the at least one digit of the hand, or of another hand of the user holding the mobile apparatus,wherein, in response to detecting the biosignal, the at least one operation switch is displayed at the display position on the touch screen arranged along a circular arc of a virtual circle having a center point located near a carpometacarpal joint of the at least one digit of the hand of the user holding the mobile apparatus and having a radius that corresponds to a distance from the carpometacarpal joint to a tip of the at least one digit of the hand of the user holding the mobile apparatus, wherein the center point and the radius are set in advance based on stochastic data, andwherein the biosensor is a photoelectric pulse wave sensor, and the detected biosignal is a photoelectric pulse wave signal, wherein the at least one operation switch is displayed at the display position on the touch screen in response to the another digit of the hand holding the mobile apparatus, other than the at least one digit of the hand, or of the another hand of the user holding the mobile apparatus touching the photoelectric pulse wave sensor.
