A controller device transmits operation data to an information processing device. The controller device wirelessly communicates with the information processing device. The controller device includes an operation unit, a generating unit, and a communication unit. The operation unit includes at least a gyrosensor, an acceleration sensor, a direction input unit, and a touch panel. The generating unit generates operation data based on data obtained from the operation unit. The communication unit wirelessly transmits the operation data to the information processing device for each iteration of a predetermined cycle. The operation data transmitted in a single transmission includes: data representing a value obtained by adding together nine pieces of angular velocity detected by the gyrosensor; data representing one piece of acceleration detected by the acceleration sensor; data representing one piece of direction detected by the direction input unit; and data representing ten pieces of position detected by the touch panel.
