Abstract: Provided is a server device with which it is possible to suitably discern whether a user uses an elevator. The server device comprises a first generation unit, a second generation unit, and an output unit. The first generation unit analyzes image data obtained from at least one or more camera devices and generates elevator information pertaining to the usage state of an elevator The second generation unit generates, on the basis of at least the generated elevator information, during-movement reference information that is referred to when the user moves. The output unit outputs the generated during-movement reference information to signage.

Abstract: It provides a portable terminal in which a user can directly operate an operation unit while looking at a display unit, in a folding state, without concentrating on the operation unit. The mobile phone is designed so that the operation body and the display body are connected at the hinge portion in a rotative way and it can be transformed from the state where the operation body and the display body fold together in a closed state to the state where the operation body and the display body are open nearly at the angle of about 180°. Key functions depending on the processing condition of the mobile phone are set at the respective keys of the input operation unit and the contents of the key functions are displayed on the display unit overlapping the image of the keys.
