Abstract: A pen-like optical input device includes a body. A light source, a light sensing unit and a lens are disposed in the body, a light ray is emitted by the light source to the outside of the body, and a reflected light ray is generated outside the body. The reflected light ray then is received by the light sensing unit after being refracted by the lens, in which the light sensing unit has a light receiving surface, and a normal of the light receiving surface inclines to an optical axis of the lens, thereby forming an angle with the optical axis.

Abstract: A specific wavelength selecting method for an optical input device includes the following steps. A light source for respectively emitting at least two light rays in different wavelength regions is first enabled. Next, the two light rays are projected to a working surface to obtain at least two corresponding reflected light rays. Then, optical signals of the reflected light rays are detected and compared to obtain a preferred optical result. Finally, a light ray in the most suitable wavelength region is selected and enabled according to the preferred optical result.

Abstract: An input device includes a motion sensor for sensing a first axis value, a distance sensor for sensing a limb distance between two limbs, and a controller. The controller is used to perform a method for controlling zooming of an object. The method includes using the motion sensor to sense the first axis value; and initiating a zooming program when the first axis value meets an initiating condition. The zooming program includes the following steps of using the distance sensor to sense the limb distance between two limbs, comparing the limb distance with a reference value; and based on a comparison result outputting a zooming control signal to zooming of an object.

Abstract: A wearable input device includes a body and a soft battery. The body is connected to the soft battery to form a collar range, and the soft battery surrounds a hand of a user. The soft battery supplies an electric power to a finger-contact control module and a wireless transmitter in the body, such that the finger-contact control module senses a movement of an object (for example, a finger) on the body, and generates a control signal corresponding to a moving position of the object, and then the wireless transmitter transmits the control signal to a computer host, thus manipulating a cursor on an operating system frame of the computer host.

Abstract: A detecting method for a pen-like optical input device with multiple optical components includes the following steps. At least two optical components for emitting light rays respectively are first enabled. The optical components are disposed within a pen-like body of the optical input device respectively at different angle. Next, the optical components separately emit light rays to a working surface respectively, so as to obtain at least two corresponding reflected light rays. Then, optical signals of the reflected light rays are detected and compared with each other to obtain a preferred optical result. Then, according to the optical result, a most appropriate optical component is selected to be enabled continuously for operation.

Abstract: A manipulation input device structure includes a foundation base and an operating base. The foundation base has a rotation slot, such that the operating base is pivoted therein, and the operating base may relatively pivots to the foundation base and is fixed at a using position or a packaging position. When the operating base pivotally rotates to the packaging position, a space occupied by the manipulation input device is smaller than a space occupied by the manipulation input device when the operating base is located on the using position.
