Abstract

The present invention relates to a method capable of automatically answering or hanging-up incoming call based on gesture-navigated operation, which is applied to a mobile phone. When receiving an incoming call signal, the mobile phone triggers a distance sensor. When determining that its distance to the adjacent object exceeds a distance threshold value, the mobile phone triggers an inclination sensor. Moreover, when determining that its inclination angle is under the erecting state (such as -130 degrees to -45 degrees), the mobile phone triggers a direction sensor. Afterwards, the mobile phone can calculate a plurality of direction angles to determine whether it is moved to the side of the ear and, if yes, the mobile phone automatically picks up the incoming call. Subsequently, after determining that the inclination angle of the mobile phone is under horizontal state (such as -10 degrees to 10 degrees), the mobile phone automatically hangs up the incoming call. Thus, by simply picking up the mobile phone and placing it close to the ear, the user is able to speak over phone. After completing the phone talk, the user is able to directly hang up the phone by simply placing it on the surface of the desk, without the need of additionally pushing the virtual answer/hang-up button, thereby greatly enhancing the convenience in use.

Method of automatically answering or hanging up an incoming call according to a somatosensory operation

The invention relates to a method for answering an incoming call or hanging up an incoming call of a mobile phone, in particular to detecting whether the user completes the answering call by detecting the inclination and the azimuth angle of the mobile phone, and automatically answering the call, or How to hang up the call.

According to, after Apple Inc. released the first generation of iPhone in 2007, the smart phone has become a popular trend and has been widely loved by people. Today, many mobile phone manufacturers, such as HTC HTC Corporation, Nokia Corporation, Samsung Electronics Co., Ltd., etc., have launched a variety of smart phones, according to market research firm Canalys According to the data, during the period of 2011, the global sales volume of smart phones was 488 million units. Therefore, in order to be able to occupy a huge market in the smart phone market, the industry will not strive to address the lack of existing smart phones. Improvement, or research and development to design new software features to improve the convenience of the use of smart phones.

Generally speaking, most of the existing smart phones use a touch panel as a display screen. This will also cause the operation mode of the smart phone, which is different from the operation mode of the traditional microphone phone. Take the action of hanging up the call as an example to illustrate the difference between the two. First, in the case of a conventional microphone phone, when it receives an incoming call and rings, the user will lie down the microphone. Pick up and put the microphone upright, hey, move the microphone to the ear to start the call, and finally, hang the microphone back to its original position to hang up the call; however, in the case of a smart phone, when it receives a call When the bell rings, the user picks up the smart phone that is lying down, so that the smart phone is in an upright state, so as to check the electric number, the user needs to slide (or touch) the virtual answer button with the finger, and After the smart phone moves to the ear, it can start talking. Finally, when the user wants to end the call, he still needs to touch the virtual hang up button with his finger before putting the smart phone back to the original position; therefore, the wisdom is known. Both the mobile phone and the traditional microphone phone have two steps of "sliding (or touching) virtual answering button" and "touching the virtual hanging button" for the action of answering/hanging the incoming call.

As mentioned above, for the elderly or young children, the operation mode of the smart phone is that it must be learned before it can correctly answer/hang up the call, that is, the operation of answering/hanging the call of the existing smart phone. The steps are not intuitive enough to cause difficulties for the elderly or young children. In particular, for the elderly, the habit of using traditional microphone-type telephones for a long time cannot be easily changed, and most elderly people usually For high-tech products, subjective psychology that causes learning difficulties, unattainable or mysterious feelings, makes smart phones less popular with older people. In addition, today's smart phones are increasingly using capacitive touch panels as display screens to enable the smart phone to support multi-touch, allowing users to perform diverse operations with different gestures. However, since the capacitive touch panel uses the capacitance change between the finger and the panel to detect the user's operation gesture, when the user wears the general glove, the smart phone cannot be operated smoothly. When the weather is cold If the smart phone receives an incoming call, the user must take off the glove before receiving the call. Otherwise, the user needs to purchase special gloves to operate the smart phone correctly. The above situation will undoubtedly reduce the wisdom. The convenience of using the mobile phone, and increasing the user's extra expenses.

Therefore, in the current fierce competition of smart phones and huge market profits, how to design a new application method to solve the above problems becomes one of the important topics for the present invention to be discussed here, and it is also a large number of consumption. New products that people are looking forward to.

In view of the operation of answering/hanging calls of existing mobile phones (such as smart phones), it is not intuitive enough, and it is different from the operation of traditional microphone phones. Therefore, the inventors finally developed after years of hard work and experimentation. The invention provides a method for automatically answering or hanging up an incoming call according to a somatosensory operation, so as to provide a better operation of answering/interrupting an incoming call by the present invention, so as to solve the problem that the elderly cannot learn easily or cannot In the case of wearing general gloves, operate a mobile phone and other issues.

An object of the present invention is to provide a method for automatically answering or hanging up an incoming call according to a somatosensory operation, which is applied to a mobile phone, mainly simulating a somatosensory operation mode of a conventional microphone type telephone, so that the user does not need to The mobile phone includes a central processing unit, a distance sensor, a tilt sensor and a position sensor, wherein the central processing unit The units are electrically connected to the sensors, respectively, to transmit a start message to the sensors, and receive the sensors The detected signal, the distance sensor can detect the distance between it and the adjacent object, the tilt sensor can detect the tilt angle of the mobile phone, and the position sensor can detect the action The azimuth angle of the phone, when the mobile phone receives an incoming call signal, the central processing unit activates the distance sensor and determines that the distance detection value transmitted by the distance sensor exceeds a distance threshold ( For example, when the mobile phone cover is opened or the mobile phone is taken out of the bag, and the display screen of the mobile phone is no longer obscured by the object, the tilt sensor is activated, and the tilt sensing is determined. When the tilt detection value is within a first tilt range value (ie, indicating that the mobile phone is in an upright state, so that the user can see the electric number), the orientation sensor is activated and received After the plurality of azimuth detection values transmitted by the position sensor, the movement angle of the mobile phone is calculated, and when the movement angle is greater than a movement threshold (ie, the mobile phone is moved to the ear), the phone is automatically answered. So, use Without the need for additional operations, will be able to quickly and automatically answer the call.

Another object of the present invention is that after the mobile phone automatically answers the call, the central processing unit will determine the subsequent tilt detection value when receiving the subsequent tilt detection value (ie, the mobile phone is next to the ear. Whether the tilt to be moved to another state is within a second tilt range value (eg, the mobile phone is in a flat state), and if so, the phone is automatically hung up to improve ease of use.

In still another object of the present invention, the mobile phone further includes a rotation sensor, wherein the central processing unit activates the rotation sensor and determines the sense of rotation before the mobile phone automatically answers the incoming call or automatically hangs up the incoming call. The rotation detection value transmitted from the detector is within the first rotation range value or the second rotation range When the value is within the range, the program that automatically answers the call or automatically hangs up the call will be executed to reduce the incidence of malfunction.

For your convenience, the review committee can make a further understanding and understanding of the purpose, technical features and effects of the present invention. The embodiments are combined with the drawings, and the details are as follows:

The present invention is a method for automatically answering or hanging up an incoming call according to a somatosensory operation, and is applied to a mobile phone. Referring to FIG. 1, in a preferred embodiment, the mobile phone 1 includes a central unit. The processing unit 11 , a proximity sensor 13 , a tilt sensor 15 , an orientation sensor 17 and a rotation sensor 19 , wherein the central processing unit 11 can be electrically connected to the first The sensors 13, 15, 17, 19 are capable of transmitting a start message to the sensors 13, 15, 17, 19 to enable the sensors 13, 15, 17, 19 to perform a detection procedure, It can receive the detection messages from the sensors 13, 15, 17, 19 to obtain the detection results of the sensors 13, 15, 17, and 19. In addition, in the following embodiments, the various angles mentioned are only one implementation manner, and depending on the manner in which the different sensor elements are installed, positive and negative angle changes may occur, for example, between the mobile phone 1 and a reference plane. When the sensor component is properly installed, the detection result is minus 90 degrees, but when the sensor component is reverse mounted, the detection result is 90 degrees and is described.

As shown in FIG. 1, in the embodiment, the distance sensor 13 can be disposed adjacent to the display screen, and can detect the distance from the adjacent object for the center. The processing unit 11 can determine when the mobile phone 1 is The front state, for example, when the mobile phone 1 is a flip phone, the distance sensor 13 can detect the distance between the display screen and the phone cover (ie, the object), so that the central processing unit 11 It can be known whether the user has opened the mobile phone cover; or, when the mobile phone 1 is a tablet type mobile phone (eg, iphone, GALAXY S3, etc.) and is placed in a bag, the distance sensor 13 can detect the distance between it and the sundries (ie, objects) in the bag, so that the central processing unit 11 can know whether the display screen of the mobile phone 1 is obscured by the sundries, and whether it has been taken by the user. Out of the bag. In addition, the tilt sensor can detect the tilt angle of the mobile phone 1, for example, when the tilt angle is 0 degrees, the mobile phone 1 is in a flat state, and when the tilt angle is minus 90 degrees, it represents an action. The phone 1 is in an upright state, and the position sensor 17 can detect the azimuth angle (azimuth) of the mobile phone 1. In particular, the so-called "azimuth angle" means that a specific direction (eg, north) as a reference starting point, and an angle (90 degrees) between the reference starting point and a specified direction (eg, east), so that the central processing unit 11 can know the displacement of the mobile phone 1. In addition, the rotation sensor 19 can detect the rotation of the mobile phone 1, so that the central processing unit 11 can know the current three-axis (Axis) space state of the mobile phone 1, for example, When the mobile phone 1 is laid flat, the display screen is up or down, or when the mobile phone 1 is upright, the broadcast position is above (ie, toward the user's head) or below (ie, toward the user's neck).

Referring to FIG. 1 , in this embodiment, although the mobile phone 1 is provided with four sensors 13 , 15 , 17 , 19 as an example , it is only for convenience of description for the general public or the art. The practitioners quickly understand the disclosure of the present invention The essence and the gist of the hardware system are not limited to the above-mentioned hardware system architecture. In actual implementation, those skilled in the art can grasp the technical features of the present invention and integrate the sensors 13, 15, 17, and 19 For a single component, or two or three components, for example, the result detected by the tilt sensor 15, the orientation sensor 17 or the rotation sensor 19 may be a gyroscope. Or a gyroscope combined with the result detected by an accelerometer (G-sensor), therefore, as long as the detection information transmitted by the sensor component can include the tilt angle, the azimuth angle and the rotation angle of the mobile phone 1, And the distance between the mobile phone 1 and the adjacent object, that is, the sensors 13, 15, 17, 19 of the present invention are combined.

Generally speaking, when the user wants to answer the incoming call, the mobile phone 1 usually has a partial fixed state. First, when the user picks up the mobile phone 1 from the bag or the desktop, the mobile phone 1 is usually laid flat. The status (as shown in Figure 2A), 嗣, the user can make the mobile phone number 1 stand upright (as shown in Figure 2B), and the user will take action when answering the call. The phone 1 moves to the side of the ear (as shown in Figure 2C). Finally, when the user finishes the call, the mobile phone 1 is put away, so that the mobile phone 1 is placed in a flat state; in addition, in other modes of use, although the user It is also possible to check the electric number when the mobile phone 1 is in a flat state, but when the mobile phone 1 is moved to the side of the ear, the mobile phone 1 is bound to change from the flat state to the erect state, so that the aforementioned In the mode of use, the mobile phone 1 will include a subsequent fixed state change, that is, from a flat state to an upright state, and a displacement occurs in the upright state, and finally changed to a flat state. Therefore, the present invention is based on the foregoing. Make Embodiment, a method of operating the somatosensory Design.

The following embodiment uses the mobile phone 1 as a tablet type mobile phone and is placed in the bag as an example for description. Referring to FIGS. 1 and 2A to 2C, when the mobile phone 1 receives an incoming call signal, the The central processing unit 11 first activates the distance sensor 13, and the distance sensor 13 detects the distance between it and the adjacent object, and generates a distance detection value to transmit the distance detection value to the center. The processing unit 11, in this embodiment, the distance sensor 13 is disposed adjacent to the display screen 110, mainly because when the user takes out the mobile phone 1 from the bag, in order to see the electric number, the user's The finger usually holds the side edge of the mobile phone 1 (as shown in FIG. 2B) without shielding the display screen. Therefore, the aforementioned setting position can avoid the problem that the distance sensor 13 is shielded by the finger. Moreover, when the central processing unit 11 reads the distance detection value, it compares the distance detection value with a distance threshold value, and when the distance detection value exceeds the distance threshold value, the mobile phone is indicated. 1 of the display screen 110 is no longer the object Covering, that is, the user has taken out the mobile phone 1 from the bag, the central processing unit 11 activates the tilt sensor 15, and the tilt sensor 15 detects the current tilt of the mobile phone 1. Angle, and generating a tilt detection value to transmit the tilt detection value to the central processing unit 11, when the central processing unit 11 receives the tilt detection value, the tilt detection value is A first tilt range value (eg, minus 130 degrees to minus 45 degrees) is compared when the tilt detection value is within the first tilt range value (ie, the tilt angle of the mobile phone 1 is negative 130) The degree to minus 45 degrees indicates that the mobile phone 1 is in an upright state, and the erect state referred to in the present invention is not limited to the fact that the mobile phone 1 is perpendicular to a plane A as long as the mobile phone 1 and the plane A are The angle θ 1 between the negative is 130 degrees to minus 45 degrees (such as the third Between the figures shown, it is the aforementioned erect state.

Referring to FIGS. 1 and 2A-2C, when the mobile phone 1 is in an upright state, the central processing unit 11 activates the orientation sensor 17, which detects the current azimuth angle of the mobile phone 1. And generating a position detection value for transmitting the position detection value to the central processing unit 11, and the central processing unit 11 sets the first received position detection value as the reference angle (ie, the user views) The caller number, the azimuth angle of the mobile phone 1), after which the central processing unit 11 continues to receive the azimuth detection value subsequently transmitted by the azimuth sensor 17 (ie, the user moves the mobile phone 1 to the ear) After that, the subsequent azimuth angle is subtracted from the reference angle and the absolute value (ie, the absolute difference) is taken to calculate the moving angle of the mobile phone. For example, please refer to FIG. 4, assuming When the mobile phone is in the north direction (ie, the user faces north), when the reference angle is 0 degrees, when the user holds the mobile phone 1 with his right hand, and the mobile phone 1 is directed to the right ear (ie, toward When the east direction is moved, the subsequent azimuth angle The absolute difference of the reference angle will gradually change from 0 degrees to 90 degrees. Similarly, when the user holds the mobile phone 1 with his left hand and moves the mobile phone 1 toward the left ear (ie, toward the west), the subsequent The absolute difference between the azimuth angle and the reference angle will also change from 0 degrees to 90 degrees.

As described above, referring to Figures 1 and 2A to 2C, the central processing unit 11 compares the moving angle of the mobile phone (i.e., the absolute difference) with a moving threshold (e.g., 45 degrees). When the moving angle is greater than the moving threshold value, it means that the mobile phone 1 has been moved to the ear by the user, after which the central processing unit 11 activates the rotation sensor 19, and the rotation sensor 19 detects Measuring the current rotation angle of the mobile phone 1 and generating a rotation detection value, To transmit the rotation detection value to the central processing unit 11, the central processing unit 11 compares the rotation detection value with a first rotation range value (eg, minus 80 degrees to minus 30 degrees). When the rotation detection value is within the first rotation range value, it indicates that the mobile phone 1 is at the top of the broadcast, and the radio position is below, that is, the direction of the mobile phone 1 held by the user is correct. The central processing unit 11 will automatically answer the incoming call. If the user holds the mobile phone 1 in the reverse direction (ie, the mobile phone's broadcast is below and the radio is above), the central processing unit 11 does not automatically answer the call. To remind the user that the current holding method is wrong.

After automatically answering the call, please refer to FIG. 1 , the central processing unit 11 will still receive the subsequent tilt detection value, and the subsequent tilt detection value and a second tilt range value ( For example, when the negative tilt detection value is within the second tilt range value (ie, the tilt angle of the mobile phone 1 is between minus 10 degrees and 10 degrees), It means that the mobile phone 1 is in a flat state. Similarly, the aforementioned flat state does not limit the mobile phone 1 to be parallel to a plane, as long as the angle θ 2 between the mobile phone 1 and the plane is minus 10 degrees to 10 degrees. Between (as shown in Figure 3), it is the aforementioned flat state. Moreover, when the mobile phone 1 is in a flat state, the representative user may have finished talking, and wants to hang up the phone. At this time, the central processing unit 11 will receive the subsequent rotation detection value, 嗣, the central processing unit 11 The subsequent rotation detection value is compared with a second rotation range value (eg, minus 10 degrees to 10 degrees), when the subsequent rotation detection value is within the second rotation range value (ie, the action The phone 1 is moved from the side of the ear to the rotation angle of the other state), indicating that the display screen of the mobile phone 1 is above (ie, toward the user's side) Towards, the central processing unit 11 will automatically hang up the phone. Otherwise, the central processing unit 11 will not hang up the phone. Therefore, when the user is in the process of the call, the mobile phone 1 is temporarily placed in a flat state due to some factors. The call is not interrupted to avoid misoperation. However, in other embodiments of the present invention, the second rotation range value may also indicate that the display screen of the mobile phone 1 is below, or other directions, to comply with the operator's Design requirements.

In addition, when the user wants to answer the call and wants to hang up the call after seeing the electric number, please refer to FIG. 1 , the user can directly put the mobile phone 1 in a flat state, that is, the central processing unit 11 is Determining that the tilt detection value of the mobile phone 1 is within the first tilt range value, and when the moving angle is less than the moving threshold value, it will receive the received subsequent tilt detection value, and the first The two tilt range values (eg, minus 10 degrees to 10 degrees) are compared, and when the subsequent tilt detection value is within the second tilt range value, the mobile phone 1 is placed in a flat state, 嗣, The rotation sensor 19 is activated to receive the rotation detection value transmitted by the rotation sensor 19. When the rotation detection value is within the second rotation range, the central processing unit 11 directly hangs. Break the call. In this way, only the elderly or children are not familiar with the operation mode of the smart phone, for example, sliding and unlocking, then touching the virtual answering button or the virtual hanging button, but by the aforementioned method of the present invention, the user only needs to be in the mobile phone 1 (For example, smart phone) When receiving the incoming call signal, pick up the mobile phone 1 and close to the ear, you can directly talk to the caller, and after the user finishes the call, just place the mobile phone 1 on the desktop. By directly hanging up the phone, without having to touch the virtual answer button or the virtual hang-up button, the operation convenience of the mobile phone 1 is effectively improved, and in addition, when the mobile phone uses a capacitive touch surface When the board is used as a display screen, the user can normally answer or hang up the phone in the case of cold weather and wearing gloves without the need to additionally add special gloves to greatly improve the use. Convenience and reduced expenses.

In order to clearly express the flow steps of the present invention, the processing procedure of the central processing unit 11 is taken as an example. Referring to FIGS. 1 and 5, after receiving the incoming call signal, the central processing unit 11 performs the following steps.
