Gesture input device

A gesture input device, configured to interact with a handheld object wherein a plurality of magnetic generators are disposed on a holding portion of the handheld object, comprising:

• a plurality of magnetic sensors, disposed on a wearable object, and configured to sense a plurality of magnetic signals provided by the magnetic generators and generate a plurality of voltage signals according to the magnetic signals;
• and
• a controller, coupled to the magnetic sensors and configured to receive the voltage signals,
• wherein when the wearable object is worn on a user's hand, the magnetic sensors are respectively located at a palm of the user's hand, and when the user's hand holds the holding portion of the handheld object, the magnetic sensors sense the magnetic signals provided by the magnetic generators and at least one of the voltage signals generated by the magnetic sensors is correspondingly changed, and the controller determines a manner that the user's hand holds the handheld object according to a pairing result between the magnetic sensors and the magnetic generators which is derived from the voltage signals generated by the magnetic sensors.

A gesture input device, configured to interact with a wearable object on which a plurality of magnetic generators are disposed, and interact with a handheld object, wherein another plurality of magnetic generators are disposed on a holding portion of the handheld object, comprising:

• a plurality of magnetic sensors, disposed on the wearable object, and configured to sense a plurality of magnetic signals provided by the magnetic generators and generate a plurality of voltage signals according to the magnetic signals;
• another plurality of magnetic sensors, disposed on the wearable object, and configured to sense another plurality of magnetic signals provided by the another magnetic generators and generate another plurality of voltage signals according to the another magnetic signals;
• and
• a controller, coupled to the magnetic sensors and the another magnetic sensors, and configured to receive the voltage signals and the another voltage signals,
• wherein when the wearable object is worn on a user's hand, the magnetic generators and the magnetic sensors are respectively located at two sides of a plurality of joints of the user's hand such that the magnetic sensors are closer to a palm of the user's hand than the magnetic generators, and when a change of a gesture of the user's hand results in different relative positions of the magnetic generators and the magnetic sensors, at least one of the voltage signals generated by the magnetic sensors is correspondingly changed, and the controller determines that the gesture of the user's hand according to the voltage signals,
• wherein the another magnetic sensors are respectively located at the palm of the user's hand, and when the user's hand holds the holding portion of the handheld object, the another magnetic sensors sense the another magnetic signals provided by the another magnetic generators and at least one of the another voltage signals generated by the another magnetic sensors is correspondingly changed, and the controller determines a manner that the user's hand holds the handheld object according to a pairing result between the another magnetic sensors and the another magnetic generators which is derived from the another voltage signals generated by the another magnetic sensors.
