A typical application circuit diagram of the apparatus for automatically adjusting the position of a virtual keyboard according to the embodiment of the present invention is shown in fig. 4;
the circuit shown in fig. 4 depicts a complete systemMainly composed of three parts shown in fig. 3, namely a sensing circuit 31, an automatic detection circuit 32 and an AP HOST chip 33. The sensing circuit 31 is composed of a sensing antenna 41 positioned on the back of the mobile terminal; the automatic detection circuit 32 is composed of an operational amplifier circuit 42, an A/D conversion circuit 43 and an MCU 44; the AP HOST chip 33 is formed by a baseband processor 45 of the mobile terminal. The induction antenna 41 is connected with the automatic detection circuit 32 through a reed, and the automatic detection circuit 32 passes an interrupt signal I2The C bus is connected to the baseband processor of AP HOST chip 33.
After the mobile terminal is started, the system circuit starts to work. When a user holds the mobile terminal by hand, the induction antenna 41 generates induction capacitance by virtue of a capacitance induction effect between the induction antenna and the hand; the positions of hands holding the mobile terminal are different, and the sizes of the induction capacitors are also different, so that the induction voltages on the induction capacitors are also different. Since the induced voltage is weak, the operational amplifier circuit 42 is required to amplify the induced voltage, the amplified signal is an analog voltage signal, the analog voltage signal is subjected to analog-to-digital conversion by the a/D converter circuit 43 to obtain a binary digital signal, the digital signal is sent to the MCU44, and the MCU converts the digital signal into two-dimensional position coordinate information (x, y) according to the magnitude of the binary digital signal, and stores the two-dimensional position coordinate information (x, y) in the internal memory as position information to be held by a human hand. When the position of the hand holding the mobile terminal is changed, the inductive capacitance between the hand and the inductive antenna 41 is changed, the hand holding position is different, the size of the inductive capacitance is also different, the change of the capacitance causes the change of the inductive voltage, so that a new inductive voltage is generated, after the inductive voltage passes through the operational amplifier circuit 42 and the A/D conversion circuit 43, the MUC44 converts the new inductive voltage into new two-dimensional position coordinate information, the new position coordinate information is compared with the original position coordinate information in the memory, when the position coordinate information is obviously changed, the MCU stores the new position coordinate information, and reports an interrupt signal to the baseband processor 45, and after the baseband processor 45 receives the interrupt signal, the I signal passes through the I/D converter circuit 452The C bus is communicated with the MCU44 to read the position coordinate information (x, y) in the internal memory of the MCU44, thereby obtaining the position of the hand-held mobile terminalThe tape processor 45 adjusts the position of the virtual keyboard to be within the single-hand touch range of the user according to the read position coordinate information (x, y).
The work flow chart for automatically adjusting the position of the virtual keyboard provided by the embodiment of the invention is shown in fig. 5, and comprises the following steps:
step 501: starting the induction circuit and the automatic detection circuit;
specifically, after the mobile terminal is normally started, the sensing circuit 31 and the automatic detection circuit 32 are started, and when a human hand holds the mobile terminal, an inductive capacitor is generated between the human hand and the inductive antenna 41 of the sensing circuit 31, and the inductive capacitor has an inductive voltage.
Step 502: detecting whether the induction information is changed;
specifically, the operational amplifier circuit 42 in the automatic detection circuit amplifies the induced voltage, converts the amplified induced voltage into a digital signal through the a/D conversion circuit 43, converts the digital signal into position coordinate information through the MCU44, compares the position coordinate information with the previous position coordinate information in the memory of the automatic detection circuit, stores the changed position coordinate information when the position coordinate information changes, and continues to execute step 503; when the position coordinate information is not changed, step 502 is executed again, and whether the sensing information is changed or not is continuously detected.
Step 503: reporting an interrupt signal;
specifically, when the position coordinate information is detected to be changed in step 502, the MCU44 reports an interrupt signal to the baseband processor 55 of the APHOST chip 33.
Step 504: the AP HOST chip acquires position coordinate information;
specifically, when the baseband processor 55 of the AP HOST chip 33 receives the interrupt signal, the position coordinate information in the internal memory of the MCU44 is read.
Step 505: the AP HOST chip adjusts the position of the virtual keyboard according to the position coordinate information;
specifically, the baseband processor 55 adjusts the position of the virtual keyboard to a range that can be touched by a single hand of the user according to the position coordinate information read in step 504.
Fig. 6 shows a schematic flow chart of adjusting a virtual keyboard position by a baseband processor of an AP HOST chip according to an embodiment of the present invention, including:
step 601: reading position coordinate information held by a human hand;
specifically, after receiving the interrupt signal reported by the MCU54, the baseband processor 55 reads the position coordinate information (x, y) in the internal memory of the MCU 55.
Step 602: adjusting the coordinate information of the virtual keyboard according to the position coordinate information;
specifically, the baseband processor 55 adjusts the offset according to the position coordinate information (x, y) read in step 601 to obtain new coordinate information (x ', y'), so that the new coordinate information (x ', y') is located at the center of the range that can be touched by one hand of the user, and the coordinate information (x ', y') is used as the coordinate information of the virtual keyboard. Wherein, the offset is a value preset in the mobile terminal by a designer according to the size of the mobile terminal, therefore, in the step, the offset is added or subtracted on the basis of the position coordinate information (x, y) to obtain new coordinate information (x ', y');
for example, a mobile terminal with a 5-inch screen may preset a longitudinal axis offset of 2cm, and assume that a central point of the mobile terminal is a coordinate origin, and a position coordinate held by a human hand is (0, 0), then new coordinate information (0, -2) may be obtained by subtracting the offset from the longitudinal coordinate, and (0, -2) is a central point coordinate of the virtual keyboard;
generally, the position of the virtual keyboard is adjusted only in the longitudinal direction, and the transverse direction is not changed, but if necessary, the offset of the longitudinal axis and the offset of the transverse axis can be preset according to the design requirements and the product characteristics, and the offset is adjusted in the longitudinal direction and the transverse direction according to the method to obtain new coordinate information.
Step 603: initializing a virtual keyboard and displaying an interface;
specifically, the baseband processor 55 initializes the virtual keyboard according to the coordinate information (x ', y'), so that the display position of the virtual keyboard on the interface is within the single-hand touch range of the user, thereby facilitating the single-hand input of the user.
Step 604: judging whether an interrupt signal is received;
specifically, after the baseband processor 55 completes the adjustment of the virtual keyboard position in step 603 and displays the position on the interface, it continues to detect whether the MCU54 reports an interrupt signal; when the baseband processor 55 receives the interrupt signal reported by the MCU54, the process returns to step 601, and readjusts the position of the virtual keyboard according to the above steps; when the baseband processor 55 does not receive the interrupt signal reported by the MCU54, the adjustment of the virtual keyboard position is completed.
It can be seen from the foregoing embodiments that, according to the method for automatically adjusting the position of the virtual keyboard of the mobile terminal provided by the invention, when a user holds the large-screen mobile terminal with one hand for inputting, the position of the user holding the mobile terminal with the hand is sensed, and the position of the virtual keyboard is adjusted to the touch range with one hand according to the holding position, so that the problem of inputting information with one hand when the user holds the mobile terminal with one hand is solved, and the user experience is greatly improved. Meanwhile, the scheme provided by the invention has the advantages of simple circuit design, reliable performance, low cost and convenience in implementation.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the principle of the present invention, and these modifications and variations should also be construed as the scope of the present invention.
