Abstract
A joystick has a related control method to provide displayed object control function. The joystick includes a body, an image sensor and a processor. The body has a deformable bottom surface whereon a pattern is disposed. The image sensor is disposed under the body and adapted to capture a frame about the pattern. The processor is electrically connected with the image sensor and adapted to generate a displayed object control signal according to pattern variation within the frame.
Claims8
A control method capable of providing displayed object control function via a deformable bottom surface of a joystick, wherein an image sensor is equipped facing the deformable bottom surface of the joystick, the control method comprising:
- receiving a frame captured by the image sensor about the deformable bottom surface;
- identifying characteristics of a plurality of dots on the deformable bottom surface from the received frame;
- and
- generating a displayed object control signal for determining whether the joystick is pinched according to characteristics of the plurality of dots within the frame, wherein the deformable bottom surface where the dots are formed on is deformed due to the pinching;
- wherein the deformable bottom surface is a part of a body having an inner space to form a hollow sunken structure, the image sensor is disposed inside the inner space, the plurality of dots forms a pattern and the pattern is deformable along with the deformable bottom surface, and the deformable bottom surface is located on an inner of a top portion of the hollow sunken structure.
