Information processing system and pen-type input device

An information processing system comprising:

• an information processing device and
• a pen-type input device, wherein
• the information processing device includes
• a sensor unit which is configured to detect contact of the pen-type input device and
• a parameter output unit which is configured to transmit feedback parameters which contain at least a parameter for controlling vibration of the pen-type input device to the pen-type input device in accordance with detection of the contact by the sensor unit,
• the pen-type input device includes
• a vibration unit and
• a vibration control unit which is configured to vibrate the vibration unit on the basis of the feedback parameters which are received and
• at least either the pen-type input device or the information processing device includes a sound output control unit which is configured to output sounds from the sound output unit at a timing which accords with the vibration of the vibration unit on the basis of the feedback parameters that the parameter output unit outputs.
