Position and trajectory detection device

A position and trajectory detecting device, in particular, can position and instantly sense the position and position change trend of the sensed object, and convert the position and position change trend into a positional message for the controller or the controlled device to interpret and process. And the position and track detection device of the track information, and the sensing sensitivity and the sensing precision are customized according to the precision of the controlled device, and the use is flexible, and has the advantages of compact structure and low manufacturing cost.

The controller is divided into: a remote controller for controlling the remote control toy, or a mouse for controlling the upstream of the computer screen and various other types of controllers.

In the case of a remote control toy, the remote control toy operates by manipulating the joystick or button on the remote control to advance, reverse, and turn the remote control car. However, if the remote control toy is to be turned, it is necessary to separately control several controls. Buttons, therefore, the control is quite rigid and hard to do whatever you want.

Taking the mouse as an example, the mouse is mainly used to move the cursor on the computer screen, and the movement of the cursor mainly depends on the sensor or optical sensor with rubber or metal ball disposed in the center of the bottom of the mouse, wherein the optical sensor The utility model mainly comprises an induction engine, an optical output lens group, an optical input lens group and a light source, wherein the induction engine mainly comprises a CMOS photosensitive element and a DPS positioning chip, and the operation principle of the mouse is that the light source is widely irradiated to the surface of the object through the light output lens group. The light reflected from the surface of the object is collected by the optical input lens group and focused onto the CMOS sensor of the induction engine. The CMOS sensor converts the image into binary bit matrix information, and the DPS positioning chip is responsible for analyzing the comparison. The difference between the front and back matrices to calculate the positional offset of the mouse cursor.

However, the disadvantage of the prior art is that the user must move the mouse through the actual movement of the mouse to detect the movement of the mouse, so the user must always let the slide The mouse moves to move the cursor on the computer screen, so when the user uses the mouse for a long time, the hand will feel uncomfortable or even injured.

In addition, the mouse must move on the surface of the object, but not every object The surface can make the optical sensor work normally. For example, a protection plate such as a glass plate or an acrylic plate is often provided on the desk, and the glass plate or the acrylic plate cannot reflect the light of the light source, so the mouse often needs to cooperate with the sliding. Use the mouse pad.

Furthermore, the number of precision electronic components and mechanical components used by prior art mice The amount of the structure is complicated, and the assembly test is time-consuming and labor-intensive. In particular, the electronic components such as the CMOS photosensitive element and the DPS positioning chip in the optical sensor are relatively expensive, so that the overall manufacturing cost of the mouse is difficult to reduce.

Therefore, it is necessary to provide a fixed point and instantly sense the position and position of the sensed object. The change trend, and the position and position change trend is converted into a position and track detection device for the position information and the track information read and processed by the controller or the controlled device. The sensing sensitivity and the sensing accuracy of the present invention are visually controlled devices. Precision and custom made, more flexible in use.

The main purpose of the present invention is to provide a position and trajectory detecting device that can be installed in a controller, comprising at least a position and trajectory generating unit and a position and trajectory sensing unit, the position and trajectory generating unit comprising a rotatable An object, the surface of the object is provided with a plurality of sensed bodies, and the position and track sensing unit is configured to sense a position of the object to be sensed by the position of the object to generate a position message and transmit to the controller, and borrow Sensing the position change trend of the sensed body to generate a track message and transmitting to the controller, thereby forming a positionable and instantaneous sensing position and position change trend of the sensed object, and positioning and position The change trend is converted into a position and track detection device for position information and track information that is interpreted and processed by the controller or the controlled device.

In an embodiment of the present invention, the surface of the object further defines a plurality of grooves, wherein a groove is provided with a sensed body, and the grooves are spaced apart from each other. Preferably, the surface of the sensed body forms a common surface with the surface of the object, or the surface of the sensed body may also be lower or higher than the surface of the object.

The position and position of the main sensor and the auxiliary sensor change trend to generate a position information corresponding to the current position of the sensed body, and generate a track message corresponding to the change trend of the position of the sensed body.

In a preferred embodiment of the present invention, the object is further arranged as a guide of a grid pattern. a line to enhance the sensing sensitivity and sensing accuracy of the position and the track sensing unit of the object to be sensed. Wherein, the controller may be a remote controller for remote control toys or a mouse for operating a computer, and the controller transmits information to a controlled device by wired transmission or wireless transmission, such as a remote control toy, a computer, and a handheld device. Electronic device or other suitable controlled device.

In the remote control of the conventional remote control car, the user must separately operate the throttle The rocker and the direction rocker can make the remote control car make a turning movement, so the user cannot control the remote control car with one hand or a single finger to make a turn or even a more advanced traveling motion.

In particular, when the creation is used as a mouse, it is only necessary to rotate the object through the finger. 11 can move the cursor, so you don't need to move the mouse position, avoid hand injury, no need to use another mouse pad, and can be used on translucent glass or acrylic plates.

The feature of this creation is that the position and trajectory detection device of the creation can be According to the controlled device to be controlled, different sensing sensitivity and sensing precision are made. For example, when the controlled device is a remote control car, if the traveling mode of the remote control car is only forward, backward, left turn and right turn, the controller only The main sensor and the object are required. If the controller is to be used as a mouse, the main sensor, several auxiliary sensors, and wires with a grid pattern can be used.
