Touch controlled pointing control system and its method

Touch-type pointing control system and method

The present invention relates to a touch-type pointing control system and method, in particular to a touch-type pointing control system and method with simple operation functions.

As the functions of electronic products become more and more powerful, users have to operate these electronic products more and more complex. Take traditional handheld electronic devices as examples, including smart phones, PDAs or remote controls. The operation method is mainly through Input keys to perform specific functions. However, as the function of electronic products increases, the number of keys required increases. Therefore, it is easy to cause the size of handheld electronic devices to be too large. , Thin, short, and small requirements, so more and more handheld electronic devices use touch-type pointing control systems to replace or reduce the number of keys.

Please refer to FIG. 1, which is a system architecture diagram of a conventional handheld electronic device 1 with a touch-type pointing control system, including a screen 12, a pointing device 14, and a touch-type pointing control system 16 , The pointing device 14 is presented on the screen 12 in the form of a cursor. The touch-type pointing control system 16 includes a movement sensor 161, a pointing control module 163 and an induction coil 165. The movement sensor 161 is a The image capturing unit is disposed on the surface of the handheld electronic device 1 and used to sense the movement direction of the finger. The pointing control module 163 controls the pointing device 14 to move according to the movement direction of the finger sensed by the movement sensor 161. The screen 12 moves synchronously and in the same direction, and the induction coil 165 is arranged around the movement sensor 161, and its main purpose is to turn on or turn off the power of the touch-type pointing control system 16 to achieve the purpose of energy saving.

Please refer to FIG. 2, which is a schematic diagram of the appearance of a hand-held electronic device 1 with a touch-type pointing control system according to the prior art. It can be seen from the figure that the screen 12, the motion sensor 161, and the induction coil 165 are arranged on the outer surface of the handheld electronic device 1. When the user touches the induction coil 165 with a finger, the touch pointing control system 16 will be When activated, the cursor of the pointing device 14 will also appear on the screen 12. At this time, the user can control the movement of the pointing device 14 (or the cursor) by simply moving a finger on the movement sensor 161.

However, the conventional technology still has inconveniences in operation. Because the area of the motion sensor 161 is small, the distance that the user's finger can move on the motion sensor 161 each time is very short. If the user needs to move the screen 12 When the upper cursor moves a long distance, the finger must be moved back and forth until the cursor moves to the destination, which causes considerable inconvenience in operation for the user.

The main reason for the inconvenience of the conventional technology is that the area of the motion sensor is too small. In addition, when the users finger is separated from the motion sensor, the touch pointing control system stops controlling the movement of the pointing device. Therefore, If the shortcomings of the touch-type pointing control system of the prior art can be overcome, the operation of the handheld electronic device will be more convenient.

The main purpose of the present invention is to provide a touch-type pointing control system, which can control the pointing device in a continuous movement state after the finger is separated from the movement sensor, so as to improve the convenience of the operation of the handheld electronic device.

Another object of the present invention is to provide a touch-type pointing control method, which can control the pointing device in a continuous movement state after the finger is separated from the movement sensor, so as to improve the convenience of the operation of the handheld electronic device.

To achieve the above object, the touch-type pointing control system of the present invention includes a movement sensor, a pointing control module, an induction coil, and a logic control module, wherein the movement sensor is used to sense the movement of a finger in the The movement direction of the sensor. The pointing control module senses the movement direction of the finger according to the movement sensor, and controls a pointing device to move in the same direction and synchronously. The induction coil is used to sense whether the finger touches the induction coil , The number of contacts and the contact interval, and output the corresponding signal, and the logic control module is electrically connected with the induction coil, and according to the signal output by the induction coil, the pointing control module is controlled to enter the standby state , Sleep state, mobile state and continuous movement state.

The method of controlling the pointing control module by the logic control module is explained as follows: a. When the pointing control device is in the dormant state, if the induction coil is sensed by the finger, it will send a first signal to the logic control module , And then the logic control module controls the pointing control device in the "standby state".

b. When the pointing control device is in the standby state, if the direction sensor senses the movement of the finger, it sends a second signal to the logic control module, and then the logic control module controls the pointing control device In the "moving state", the pointing device will move synchronously and in the same direction with the moving direction and distance of the finger on the direction sensor.

c. When the pointing control device is in a moving state, if the motion sensor senses that the finger moves to the edge of the detection range, when the finger moves away from the detection range and does not touch the induction coil, a third signal is sent to the The logic control module controls the pointing control device in the "continuous movement state" by the logic control module. At this time, the pointing device will continue to move according to the moving speed and direction before the finger leaves the movement sensor.

d. When the pointing control device is continuously moving, if the motion sensor senses that the finger touches the induction coil, it sends a fourth signal to the logic control module, and then the logic control module causes the pointing The control device is controlled in the "standby state", at this time the pointing device will immediately stop moving.

e. When the induction coil is not sensed by the finger for a period of time T, a fifth signal is sent to the logic control module, and the logic control module controls the pointing control device in the "sleep state" , To achieve the purpose of energy saving.

In order to further reveal the advantages and spirit of the present invention, a detailed description is given below in conjunction with the drawings.
