Abstract: A wiper operation system for a construction machine, enabling a plurality of wiper operating modes set for the operation of the wiper device to be easily checked and being capable of preventing erroneous selection of the wiper operating mode, includes a display, an operation reception unit that receives a mode selection operation for selecting one wiper motion mode from among a plurality of wiper motion modes, and a wiper control section that makes the wiper device perform a motion in the selected wiper motion mode. The display includes a wiper motion display unit performing a display of a plurality of icons corresponding to a plurality of wiper action modes respectively, and an identification display enabling the icon of the selected wiper action mode to be identified.

Abstract: An information processing system is provided, including: a sensor provided in a working machine; and a key information generator that generates key information based on one or more sensor values received from the sensor, the key information generator being provided in the working machine, the key information being used to transmit and receive information between the working machine and an external device provided outside the working machine. An information processing method and a non-transitory computer-readable recording medium are also provided.
