FIG. 2A is a drawing for explaining an operation of an electronic device to identify a touch by a finger and a touch by a palm through a touch pad according to one embodiment.

Referring to FIG. 2A, according to one embodiment, the electronic device (201) may be implemented as a computing device (e.g., a PC or a laptop). According to one embodiment, the touch pad (202) may be implemented as a touch pad included in the computing device.

According to one embodiment, the electronic device (201) may execute a palm rejection function to determine that the touch (203) by the palm is an invalid touch and ignore the touch (203) by the palm when the touch identified on the touchpad (202) is identified as a touch by the palm (203).

According to one embodiment, the electronic device (201) may execute a palm rejection function that determines that the touch (204) by the finger is also an invalid touch and ignores the touch (204) by the finger when a touch (203) by the palm is detected while the touch (204) by the finger is moving.

However, conventionally, when a touch by a finger is detected while a touch by a palm is moving at a specific location on the touchpad, the electronic device would judge only the touch by the palm as an invalid touch and ignore only the touch by the palm, and could confirm the input corresponding to the touch by the finger. Therefore, conventionally, the electronic device had the problem of confirming the input corresponding to the touch by the finger that was not intended by the user.

That is, the electronic device (201) according to one embodiment can individually determine a touch by a finger (204) and a touch by a palm (203), and additionally determine whether the touch by the palm (203) is moving, and thereby determine whether to ignore the touch by the finger (204). If the touch by the palm (203) is moving, the electronic device (201) according to one embodiment can update the information indicating the touch by the palm to the information about the touch by the finger (204), and ignore the touch by the finger (204) according to the palm rejection function. Accordingly, if the touch by the finger (204) is confirmed while the touch by the palm (203) is moving, the electronic device (201) can determine that the touch by the finger (204) is an unintended touch by the user, and can ignore the touch by the finger (204).

FIG. 2b is a schematic block diagram of an electronic device according to one embodiment.

Referring to FIG. 2B, the electronic device (201) may include a touch pad (202), a sensor IC (240), and a processor (250). According to one embodiment, the sensor IC (240) may include a control circuit (220) and a memory (230) (e.g., the memory (130) of FIG. 1). According to one embodiment, the memory (230) is illustrated as a configuration included in the sensor IC (240), but may be implemented as a separate configuration from the sensor IC (240).

According to one embodiment, the electronic device (201) may be implemented identically or similarly to the electronic device (101) of FIG. 1. According to one embodiment, the processor (250) may be implemented identically or similarly to the processor (120) of FIG. 1.

According to one embodiment, the electronic device (201) may be implemented as a computing device (e.g., a personal computer or a laptop). According to one embodiment, the touchpad (202) may be implemented as a touchpad included in the computing device. Alternatively, according to one embodiment, the electronic device (201) may be implemented as a smartphone or a tablet PC. In this case, according to one embodiment, the touchpad (202) may be implemented as a touchscreen included in the smartphone or tablet PC. However, this is only an example, and the electronic device (201) may be implemented as various devices.

According to one embodiment, the touch pad (202) may include a circuit (e.g., a digitizer) capable of sensing touch based on an electro magnetic resonance (EMR) method.

According to one embodiment, the control circuit (220) can sense or confirm a touch by the user's body (e.g., palm, fingers) through the touch pad (202). For example, the control circuit (220) can sense a touch by the user's body and provide information (or a sensing value) about the touch to the processor (250).

For example, the control circuit (220) may provide the processor (250) with coordinate information about the point (or area) where the user's body is touched, information about the type of touch (e.g., touch by the palm or touch by the finger), and information to ignore the touch or confirm an input corresponding to the touch.

According to one embodiment, the control circuit (220) can generate information about a touch by a palm (e.g., a palm touch) so that the touch can be ignored, and provide the generated information to the processor (250). The processor (250) can check the information and ignore the touch by a palm (e.g., a palm touch).

According to one embodiment, the control circuit (220) can generate information about a touch so as to be able to confirm a touch by a finger, and provide the generated information to the processor (250). The processor (250) can confirm the information and confirm an input corresponding to the touch.

According to one embodiment, the control circuit (220) can identify a first touch by a palm and a second touch by a finger. For example, if the control circuit (220) determines that the area corresponding to the first touch is larger than a designated area, the control circuit (220) can identify the first touch as a touch by a palm. For example, if the control circuit (220) determines that the area corresponding to the second touch is not larger than the designated area, the control circuit (220) can identify the second touch as a touch by a finger. For example, the designated area may include a reference area identified as a touch by a palm by the control circuit (220). For example, the designated area may be set by the user or automatically set by the control circuit (220).

According to one embodiment, the control circuit (220) can determine whether the first touch has moved. According to one embodiment, the control circuit (220) can determine that the first touch has moved if it is determined that the first touch, which has been confirmed at a first location of the touch pad (202), has moved to a second location different from the first location without being released.

For example, the control circuit (220) can determine that the first touch has moved if the first touch confirmed at the first location of the touch pad (202) is confirmed at a second location that is greater than a specified distance from the first location while the first touch is not released. For example, the control circuit (220) can determine that the first touch has not moved if the first touch confirmed at the first location of the touch pad (202) is confirmed at a third location that is not greater than a specified distance from the first location while the first touch is not released. For example, the specified distance may include a reference distance at which it is determined that the first touch has moved. For example, the specified distance may be set to 10 mm. However, this is an example, and the specified distance may be set to various values, and may be set by the user or automatically set by the control circuit (220).

According to one embodiment, when the first touch is confirmed, the control circuit (220) may determine first information about the first touch. For example, the first information may include information for ignoring the first touch. According to one embodiment, the control circuit (220) may update the first information about the first touch with information indicating a touch by a palm. For example, the first information about the first touch may include coordinate information about the point where the first touch is confirmed, information indicating that the first touch is a touch by a palm, and information for ignoring the first touch. However, this is an example, and the first information about the first touch may further include various information, or some information may be omitted. According to one embodiment, the control circuit (220) may provide the first information about the first touch to the processor (250). According to one embodiment, the processor (250) may ignore the first touch based on the first information about the first touch.

According to one embodiment, when a second touch is confirmed while a first touch is moving, the control circuit (220) may confirm second information about the second touch as information indicating a touch by a palm. For example, the second information may include information for ignoring the second touch. According to one embodiment, the control circuit (220) may update the information indicating a touch by a palm to the second information about the second touch. For example, the second information about the second touch may include coordinate information about a point where the second touch is confirmed, information indicating that the second touch is a touch by a palm, and information for ignoring the second touch. However, this is an example, and the second information about the second touch may include various additional information or may omit some information. According to one embodiment, the control circuit (220) may provide the second information about the second touch to the processor (250). According to one embodiment, the processor (250) may ignore the second touch based on the information about the second touch.

According to one embodiment, when the second touch is confirmed and the first touch is confirmed not to have moved, the control circuit (220) may confirm second information about the second touch as information indicating a touch by a finger. For example, the second information may include information for confirming an input corresponding to the second touch. According to one embodiment, the control circuit (220) may update the information indicating a touch by a finger to the second information about the second touch. For example, the second information about the second touch may include coordinate information about a point where the second touch is confirmed, information indicating that the second touch is a touch by a finger, and information for confirming an input corresponding to the second touch.
