Provided is an example system in which an operation device includes a vibrator configured to vibrate at a specified frequency. When the vibrator vibrates at a first frequency, an upper portion of the operation device vibrates strongly. When the vibrator vibrates at a second frequency, a lower portion of the operation device vibrates strongly. When a cursor is located at an upper portion in a list, the vibrator is vibrated at the first frequency, whereby the upper portion of the operation device is caused to vibrate strongly. When the cursor is located at a lower portion in the list, the vibrator is vibrated at the second frequency, whereby the lower portion of the operation device is caused to vibrate strongly.
