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 plurality of frames 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 plurality of frames.

A joystick, comprising:
- a body having an enclosed space, and further having a deformable bottom surface whereon a pattern is disposed, wherein the pattern is deformable along with the deformable bottom surface;
- an image sensor disposed inside the enclosed space and adapted to capture a plurality of frames about the pattern;
- a processor electrically connected with the image sensor and adapted to generate a displayed object control signal for determining whether the joystick is pinched or operated by other gestures according to pattern variation within the plurality of frames;
- and
- a light source disposed under the body and adapted to project a beam onto the deformable bottom surface;
- wherein the body is a hollow sunken structure, the deformable bottom surface is located on an inner of a top portion of the hollow sunken structure.
A control method capable of providing displayed object control function via a deformable bottom surface of a joystick, the control method comprising:
- an image sensor of the joystick acquiring a plurality of frames about the deformable bottom surface;
- a processor of the joystick identifying characteristics of a plurality of dots on the deformable bottom surface;
- and
- the processor of the joystick generating a displayed object control signal for determining whether the joystick is pinched or operated by other gestures according to characteristics variation of the plurality of dots within the plurality of frames;
- wherein the deformable bottom surface is a part of a body having an enclosed space, the image sensor is disposed inside the enclosed space, a pattern is deformable along with the deformable bottom surface, a light source of the joystick is disposed under the body and adapted to project a beam onto the deformable bottom surface, the body is a hollow sunken structure, and the deformable bottom surface is located on an inner of a top portion of the hollow sunken structure.
