Abstract: A CPU determines whether a first condition related to a current position of a subject is satisfied, determines whether a second condition different from the first condition and related to at least one of the current position of the subject and a motion state of the subject is satisfied, and controls a display mode of a display unit on the basis of a determination result as to whether the first condition is satisfied and a determination result as to whether the second condition is satisfied.

Abstract: At least one processor that identifies which of a plurality of exterior bodies individually formed in advance is an exterior body attached to a main body of an electronic device capable of executing at least a first function and a second function which are not display functions and are different from each other, enables at least the first function of the electronic device and disables at least the second function of the electronic device when the identified exterior body is a certain exterior body among the plurality of exterior bodies, and enables at least the second function of the electronic device and disables at least the first function of the electronic device when the identified exterior body is another exterior body different from the certain exterior body among the plurality of exterior bodies.

Abstract: An information display device includes a display and a processor. The display displays product information. The processor determines whether or not information relating to the product information is printable. The display displays a printability indication indicating that the information relating to the product information is printable in a case where the processor determines that the information relating to the product information is printable.

Abstract: Provided is a content output apparatus including: an acquisition unit configured to acquire, from a communication partner terminal, language information used by the communication partner terminal; and an output unit configured to output a content on the basis of the language information.

Abstract: A CPU determines whether or not the display position of a link character string is finger-touched when a touch sensor on a screen constituting a display unit is finger-touched, and when the link character string is touched, a user is informed that a jump to a link destination is possible through screen vibration or the like.

Abstract: When detecting that an other cellular phone device 1 is present in the vicinity of a local cellular phone device 1 through a short-range wireless communication unit 24, a CPU 11 receives and acquires a communication-partner ID from the other cellular phone device 1 through the short-range wireless communication unit 24. Next, the CPU 11 creates a e-mail indicating that the communication partner is present in the vicinity of the local cellular phone device based on the communication-partner ID. Further, the CPU 11 sends a predetermined communication terminal 4 of the created e-mail from a telephone communication unit 15 through a public mobile communication network 2.
