Abstract
A prompting device for an optical finger navigation sensor, a prompting method thereof, and a prompting system are provided. The prompting device includes at least one light-emitting unit, which is disposed around the OFN sensor. The prompting device is integrated with the OFN sensor. According to the finger position transmitted back to the operating system from the OFN sensor and the action that the operation system can do accordingly, the light-emitting unit provides a blue or green optical indication for the user to perform the next action. Or when the operation system performs the action needed to prompt, the prompting device can prompt the user for the next action. Therefore, the optical indication of the present invention can prompt the user to perform the action, thereby providing a convenience for the user.
