Background

To meet ergonomic requirements, the surface of the touch mouse may be designed to fit the palm of the user's hand. In this case, the finger shape of the finger detected from the surface of the touch mouse is not the same as the finger shape of the fingertip detected by the touch panel. Further, when the user operates the touch mouse, a finger is always placed on the surface of the touch mouse to operate the mouse, which may cause a wrong gesture command of the finger movement unintended by the user.

Detailed Description

Various exemplary embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some exemplary embodiments are shown. The inventive concept may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive concept to those skilled in the art.

FIG. 1 is a schematic view of a handheld device of the present invention. Fig. 2 is a system block diagram of a touch controller of a handheld device according to an embodiment of the invention. Referring to fig. 1 and 2, the handheld device 1 includes a body 2 having an operation surface 3, and the touch controller of the handheld device 1 includes a touch sensor 4, a displacement sensor 5, a processor 6, at least one key 7 and a storage unit 8. The touch sensor 4 is configured to sense a touch on the operation surface 3 to output a touch signal. The displacement sensor 5 is disposed on the body 2 and senses a displacement of the body 2 to output a displacement signal. The key 7 outputs a key signal when pressed. The processor 6 is connected to the touch sensor 4 to receive the touch signal. The processor 6 is connected to the displacement sensor 5 to receive the displacement signal. The processor 6 is connected to the keys 7 to receive the key signals. The processor 6 is connected to the storage unit 8 to read a plurality of values in the storage unit 8 and compare the values with a measurement value. The handheld device 1 may be a touch mouse, a smart phone, a touch pad, etc., but the invention is not limited thereto.

When the processor 6 receives the touch signal, the processor 6 generates a control command. For example, when the handheld device 1 is the touch mouse as shown in fig. 1, the control command may be sent to a host computer to scroll pages on a web page or perform a shortcut gesture. When the handheld device 1 is a smartphone, the processor 6 may execute the control command on a screen, such as a swipe, click, or rotation.

In one embodiment, the handheld device 1 is a touch mouse. The processor 6 receives the touch signal and the displacement signal generated corresponding to the displacement of the body 2. When the displacement signal is greater than a movement threshold, the processor 6 disables the touch sensor 4 and/or the touch signal for a first time interval, such as 1 microsecond, 1 millisecond, 1 second, etc., but the invention is not limited thereto.

In this case, the touch signal may be considered as an unintentional action of the user. The displacement signal represents a displacement of the body 2, for example a distance between two different positions or two different coordinates. The storage unit 8 stores a plurality of movement threshold values, and the movement threshold value stored in the storage unit 8 is set to one of the movement threshold values on the basis of an operation mode of the handheld device.

In addition, the processor 6 may also accumulate a plurality of displacement signals in a movement time interval and compare the accumulated displacement signals with the movement threshold. The storage unit 8 stores a plurality of moving time interval values, and the moving time interval stored in the storage unit 8 is set to one of the moving time interval values based on an operation mode of the handheld device 1. It should be noted that the time length of the first time interval may be the same as the time length of the moving time interval, but the invention is not limited thereto.

Further, the disabling of the touch signal by the processor 6 in the first time interval may be represented by the processor 6 ceasing to generate the control command formed by the received touch signal in the first time interval, the processor 6 ceasing to receive the touch signal in the first time interval, or the processor 6 resetting the received touch signal to represent no touch in the first time interval when the received touch signal does not form the control command.

For example, the handheld device 1 is a touch mouse. When the user moves the touch mouse as shown in fig. 1, the user may unintentionally touch the operation surface 3. The processor 6 receives the touch signal sensing the touch on the operation surface 3 via the touch sensor 4, and receives the displacement signal sensing the displacement of the touch mouse via the displacement sensor 5. When the processor 6 determines that the displacement signal (e.g., a distance signal representing a distance such as 3cm) is greater than the movement threshold (e.g., 0.5cm), the processor 6 disables the touch sensor 4 and the touch signal during the first time interval regardless of whether the control command is formed by the touch signal. In this way, the processor 6 determines that the user merely moves the touch mouse and does not intend to touch on the operation interface 3. It should be noted that the distance signal may be represented by the touch mouse moving a distance relative to the desktop or the mouse cursor moving several pixels on an image array in the screen.

Fig. 3 is a flowchart of a control method of an embodiment of the present invention. The processor 6 executing the control method includes step S101: receiving a touch signal sent by the touch sensor 4, for sensing a touch on the operation surface 3 to output a control command; s103: when a displacement signal sent by the displacement sensor 5 for sensing a displacement of the body is greater than a movement threshold, the touch signal is disabled in a first time interval.

The hand-held device 1 is a touch mouse, and a user can click the button 7 on the touch mouse, move the touch mouse, and touch the operation interface 3. When the user moves the touch mouse, the user may unintentionally touch the operation surface 3. At this time, the processor 6 receives the touch signal and the displacement signal at the same time. When the processor 6 determines that the displacement signal is greater than the moving threshold, the processor disables the touch sensor 4 and/or the touch signal in a second time interval.

In one embodiment, the handheld device 1 is a touch mouse. The key 7 outputs a key signal when pressed, and the processor 6 receives the key signal. When the user clicks the key 7, the user will also touch the operating surface 3 unintentionally. At this time, the processor 6 receives the touch signal and the key signal at the same time. When the processor 6 determines that the key 7 is pressed, the processor 6 disables the touch sensor 4 and the touch signal in the second time interval, and outputs a key control signal. It should be noted that the time length of the second time interval may be the same as the time length of the first time interval, but the invention is not limited thereto.

In this case, the touch signal may be considered as an unintentional motion of the user. The processor 6 disabling the touch signal in the second time interval may be represented by the processor 6 stopping generating the control command formed by the received touch signal in the second time interval, the processor 6 stopping receiving the touch signal in the second time interval, or the processor 6 resetting the received touch signal in the second time interval to represent no touch when the received touch signal does not form the control command.

For example, when the user presses the key 7, the user unintentionally touches the operation surface 3. The processor 6 receives the touch signal sensing the touch on the operation surface 3 via the touch sensor 4 and receives the key signal of the key 7 being pressed. When the processor determines that the key 7 is pressed, the processor 6 disables the touch sensor 4 and/or the touch signal during the second time interval regardless of whether the control command is formed by the touch signal. In this way, the processor 6 determines that the user clicks the button 7 instead of intending to touch the operation interface 3.

Fig. 4 is a flowchart of a control method according to another embodiment of the present invention. The processor 6 executing the control method includes step S301: and judging that the key 7 is pressed so as to disable the touch signal in a second time interval and output a key control signal.

When the processor 6 determines that the key 7 is pressed by the user, the processor 6 disables the touch sensor 4 and/or the touch signal in the second time interval.

Based on the above, the touch controller of the handheld device and the control method thereof of the present invention can use the physical keys and the touch detection to assist the adjustment of the gesture command, so as to avoid the occurrence of the wrong gesture command.

The above-mentioned embodiments are merely preferred embodiments of the present invention, and all equivalent changes and modifications made in the claims of the present invention should be covered by the present invention.
