Abstract
A wristwatch includes a case and a corresponding crystal, and an integrated circuit sized to be received with the case. The wristwatch has a first, second, third, and fourth capacitive touch sensor adapted to be located beneath the crystal and within the case when the wristwatch is assembled. The capacitive touch sensors are in electrical communication with the integrated circuit to control operation of the wristwatch. The capacitive touch sensors are located adjacent to the periphery of the crystal and are spaced apart.
Claims15
A wristwatch comprising:
- a case and a crystal;
- an integrated circuit received within the case;
- and
- first, second, third, and fourth capacitive touch sensors located beneath the crystal and in electrical communication with the integrated circuit to control operation of the wristwatch;
- wherein the capacitive touch sensors provide four inputs to the integrated circuit to control operation of the watch, the first input through a user activating the first sensor, the second input through the user activating the second sensor, the third input through the user sweeping along the crystal and activating the first sensor prior to the second sensor within a predetermined time limit, and the fourth input through the user sweeping along the crystal and activating the second sensor prior to the first sensor within the predetermined time limit;
- wherein the capacitive touch sensors provide a fifth input to the integrated circuit to control operation of the watch, the fifth input through the user sweeping along the crystal and activating the first sensor, the second sensor, and the third sensor in sequence within another predetermined time limit;
- wherein the fifth input unlocks a touch function for the wristwatch with the first sensor continuously activated for at least a predetermined time period before the second and third sensors are activated by sweeping;
- and
- wherein each capacitive touch sensor is spaced apart from an adjacent capacitive touch sensor.
