Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for tap control and its control module for making it unnecessary to touch and release the finger or another object on a touch pad in a short time, resulting in requiring relatively small force and suppressing erroneous judgement. <P>SOLUTION: This tap control method is provided to make the control module of a touch controller identify the contact operation of an object on a touch controller, and to supply a control signal to be generated corresponding to the contact operation for the use of the following control function of a host, and to set a reference time in the control module. This tap control method is provided to detect the generation of the contact operation to be generated by the object on the touch controller, and to start measurement, and to continue to detect it, and to record the stay time of the object on the touch controller. When the stay time of the object exceeds the reference time, and the generation of the contact operation valid in the reference time is detected only once, a control signal expressing the contact operation is outputted, and supplied for the use of the host. When the stay time exceeds the reference time, it is judged that the contact operation is valid, and it is not necessary for the object to instantaneously separate from the controller so that power saving effects can be achieved. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a touch control method and a control module thereof, and more particularly, to a tap control method and a control module thereof that can be operated easily without a force.

Most software currently set up on computers displays window screens using a graphical user interface (GUI) method. The advantage of this is that the user can move auxiliary pointing devices such as mice and trackballs in a plane. For example, the cursor displayed on the computer can be moved to the corresponding position by the pointing device and operated on the window screen of the computer. Since this method matches the operation control method visualized by mankind, such a simple method is universally applied to various electronic products having a window screen.

In addition to commonly used pointing devices such as mouse devices and trackball devices, there are also devices that perform similar operations using touchpads and touch panels combined with screens. In view of the trend of gradually replacing desktop personal computers with desktop personal computers, the application range of touch control devices such as touch pads and touch panels that are small in volume and can be combined with electronic products will increase accordingly.

As shown in FIG. 1, the current signal processing method of the touch pad 110 will be described. The touch pad 110 is pressed to generate an analog press signal, the controller 120 performs analog / digital conversion, calculates the coordinate value of the contact point, and at the same time, the user taps (tap or clicks), double taps When it is identified whether or not to generate a gesture such as (double tap or double click), drag, or move, a control signal corresponding to the gesture is transmitted to the host 130 and the cursor on the screen 140 of the host 130 is controlled. Perform operations such as movement, object selection, and program execution.

As shown in FIG. S. Pat. No. In the touch control method for identifying the tap gesture submitted by 6,380,931, the determination of the tap gesture is a press signal 901 generated by tapping the touch pad once within the time t _{1 when the} finger is extremely short, This for the first time pulse time outputs a control signal 902 to t _2, to achieve the operations such object selection, program execution. That is, since the finger must be raised after the lowered within a short period of time t ₁ on the touch pad, the following disadvantages occur.
(1) This operation requires considerable power for the execution of a simple function.
(2) A misjudgment occurs because it is not possible to effectively suppress short noise that tends to cause a temporary pressing phenomenon.
U. S. Pat. No. 6,380,931

The known tap control method requires power and solves the disadvantage of being prone to misjudgment, and does not require a finger or other object to be lowered on the touchpad within a short time, thus requiring relatively high power. It is another object of the present invention to provide a tap control method and a control module thereof that are less prone to misunderstanding.

The tap control method of the present invention is a method for identifying a contact motion of an object on the touch control device by the control module of the touch control device, and further generating a control signal corresponding to the touch motion by a subsequent control function of the host. A reference time is set in the control module.
The tap control method detects the occurrence of a contact motion generated by the object on the touch control device, starts timing, and continues to detect and records the stop time of the object on the touch control device. If the stationary time of the object exceeds the reference time and the generation of a valid contact action is detected only once within the reference time, a control signal indicating the contact action is output to be used by the host. Provide.

The control module of the present invention is used to identify a contact motion on an object touch control device, and further provides a different control signal generated in response to the touch motion for use in a subsequent control function of the host. The module comprises a calculation unit and a gesture unit connected to the calculation unit and the host.
Each time the computing unit detects the appearance of the object on the touch control device, it generates a corresponding press signal, and each press signal corresponds to the start time of appearance on the touch control. The generation starts and ends when the appearance of the current time is finished. The gesture unit is used to receive these pressing signals, and further, based on these pressing signals, calculates the time of appearance of the object on the touch control device and the accumulated movement amount to identify the movement of the object. The reference time is set in the gesture unit.
The gesture unit detects the occurrence of a contact operation generated by the object on the touch control device and starts timing, and continues the detection to record the stop time of the object on the touch control device. When the stationary time of the object exceeds the reference time and the generation of an effective contact operation is detected only once within the reference time, a control signal indicating the contact operation is output for use by the host.

Compared with the known tap control method, if the finger is not lowered and raised within a short period of time, the tap control method of the present invention is not recognized as an effective touch motion. Since it is determined that the contact operation is effective only after the reference time T exceeds the reference time T, and it is not necessary to instantly remove the finger or other object from the touch control device, it is more labor-saving and temporary. Short noise that easily causes a pressing phenomenon can be effectively suppressed, and there is an advantage that it is difficult to cause misunderstandings. This improves elasticity and convenience when using the touch control device.

As shown in FIG. 3, in the preferred embodiment of the control module 13 of the present invention, the control module 13 can be modularly mounted and connected between the touch control device 10 and the host 3. The main actions are the X and Y coordinate position parameters detected by the X direction processing unit 11 and the Y direction processing unit 12 on the touch control device 10 for the finger 2 or other object, and the touch of the finger 2 or other object. Various pressing positions due to pressing by the control device 10 are detected, a pressing signal 101 corresponding to the position is output, this is converted into a corresponding control signal 102, and used for the host 3 through the transmission interface 14. . The host 3 may be a device such as a general personal computer, a notebook personal computer, or a portable electronic product.

The control module 13 includes a calculation unit 131 and a gesture unit 132 connected between the calculation unit 131 and the host 3. Each time the calculation unit 131 detects the appearance of the finger 2 or other object on the touch control device 10 once, the calculation unit 131 generates a corresponding press signal 101, and each press signal 101 touches the finger 2 or another object. Generation is started in response to the start time of appearance on the control device 10, and is stopped after the end of the appearance.

The gesture unit 132 is used to receive the pressing signal 101, and further calculates the time of appearance of the finger 2 or other object on the touch control device 10 and the cumulative movement amount based on the pressing signal 101, and the finger 2 or other Identify the motion of the object. A reference time T is set in the gesture unit 132.

  As shown in FIGS. 4 and 5, the tap control method according to the present invention is a gesture unit when a contact operation of a finger or other object on the touch control device 10 occurs as shown in flows 401 and 402. 132 detects and starts timing, and continues the detection to record the stop time of the finger or other object on the touch control device 10. In FIG. 5, the positive edge (temporary state during the transition from the low level to the high level) of the waveform of the pressure signal 101 indicates the occurrence of the contact operation.

  As shown in a flow 403, when the contact operation of the finger or other object with the touch control device 10 exceeds the reference time T, that is, the cumulative time obtained from the gesture unit 132 reaches the reference time T, the time is measured. Upon termination, as shown in flow 404, if the gesture unit 132 detects the generation of a valid contact action only once within the reference time T, it may determine that this contact action is a tap gesture, If the conditions of the flows 403 and 404 do not match, as shown in a flow 405, it is determined as a non-tap gesture and another operation is determined.

The flow 403 “contact operation of the finger or other object to the touch control device has exceeded the reference time T” and the flow 404 “effective contact operation has been generated only once within the reference time T” If the condition is met, the flow 406 is performed, and the control signal 102 for the tap gesture as shown in FIG. 5 is output. This control signal 102 is output only after the tap gesture occurs and the reference time T has elapsed. The host 3 is then used. That is, if the stop time of the finger 2 or another object on the touch control device 10 exceeds the reference time T, the control signal 102 is sent to the host 3.
