A keyboard device includes a key switch corresponding to a character, a plurality of touchpads, a memory to store mapping information, a communication interface to communicate with an information processing apparatus, and circuitry. In the mapping information, a code to be output to the information processing apparatus is set for each combination of operations on the plurality of touchpads. When a combination of operations on the plurality of touchpads is received, the circuitry identifies a code corresponding to the combination of operations on the plurality of touchpads based on the mapping information and outputs the identified code to the information processing apparatus via the communication interface.
