Provided is an information input system, wherein an operator can easily conduct information input actions to a small information device. The information input system is provided with a vibration element that applies a vibration to a forefinger of an operator, a vibration sensor that measures the vibration transmitted through the forefinger and the thumb, and a first input information specifying module that specifies the position on the thumb where another finger of the operator is in contact with the thumb based on a change in transmission property of the transmission system caused by the fact that the finger of the operator, which is in contact with the thumb, is in contact with the vibration transmission system formed by including the forefinger and the thumb. The information input system outputs the detected position of the contact of the finger as positional information.
