OPTICAL FINGER NAVIGATION DEVICE WITH INTEGRATED TACTILE SWITCH |
摘要 |
A system of a tactile switch and an optical navigation device. The system includes a user device. The user device includes an optical finger navigation device. The optical finger navigation device enables a user to control a function of the user device via the optical finger navigation device. The optical finger navigation device includes a circuit board, a sensor array electrically coupled to the circuit board, and a tactile switch electrically coupled to the circuit board. The sensor array detects light and generates a navigation signal that corresponds to the detected light. The tactile switch is physically aligned with the sensor array on the circuit board. The tactile switch generates a switch signal upon actuation of the tactile switch in response to a force on a packaging structure of the sensor array.
