Example 1
A control system for a display screen Dock of a terminal disclosed in embodiment 1 of the present invention is described below with reference to fig. 1(a), fig. 1(b), and fig. 1 (c). Fig. 1(a) is a schematic structural diagram of a control system of a Dock bar of a terminal display screen disclosed in embodiment 1 of the present invention, fig. 1(b) is a schematic non-interfering near field distribution diagram of a target area of a near field inductor disclosed in embodiment 1 of the present invention, and fig. 1(c) is a schematic interfering near field distribution diagram of a target area of a near field inductor disclosed in embodiment 1 of the present invention. Although two near field sensors are illustrated in fig. 1(a), 1(b), and 1(c), the number of near field sensors is not limited to two, and the positions where the near field sensors are disposed on the terminal display screen may be set according to actual requirements, and the embodiment of the present invention is not limited thereto, and the terminal display screen is illustrated as an in-vehicle display screen in fig. 1(a), 1(b), and 1(c), and in addition, the terminal display screen may be a mobile phone, a tablet, a notebook computer, or the like.
As shown in fig. 1(a), a control system 1 for a Dock bar of a display screen of a terminal includes: the near field inductor 10 is arranged at the peripheral part of the terminal display screen 20 where the Dock bar is arranged, and the near field inductor 10 is used for detecting the near field of a target area of the near field inductor 10.
And the controller 30 is connected with the near field inductor 10, and is used for controlling the Dock bar arranged at the peripheral part of the screen to be in the unfolding state when the near field detected by the near field inductor 10 is changed when the target object approaches the near field inductor 10.
In particular, the near field is an inductive field that includes an electrostatic field and a static magnetic field, which may be selected to be a hall sensor for the near field inductor 10. As shown in fig. 1(b), when there is no interfering substance in the target area around the terminal display screen where the near field sensor 10 is disposed, the field around the near field sensor 10 is uniformly dispersed as shown in fig. 1(b), and when there is an interfering substance in the target area of the near field sensor 10, the field around the near field sensor 10 is non-uniformly dispersed as shown in fig. 1 (c). When the near field sensor 10 is a hall sensor, when the field in the target area of the near field sensor 10 is uniformly dispersed as shown in fig. 1(b), the signal value of the output signal of the hall sensor is relatively uniform when the hall sensor continuously detects the field in the target area, and when the field in the target area of the near field sensor 10 is non-uniformly dispersed as shown in fig. 1(c), the signal value of the output signal of the hall sensor is suddenly changed from a normal value when the hall sensor continuously detects the field in the target area, which results in a relatively large range of fluctuation.
Specifically, as an alternative embodiment of the present application, the target area may be a circular area formed by taking the position of the near-field inductor 10 as a center point and a predetermined distance as a radius. In order to accurately sense the proximity of the target object to the near-field sensor 10 and the sensing effect of the near-field sensor 10, the predetermined distance may be 2 cm, and the target object may be a finger.
For the terminal display screen, the terminal display screen can be a mobile phone display screen, a flat panel display screen, a touch screen computer display screen, a vehicle-mounted display screen and the like.
The controller 30 may be a single chip microcomputer, a Field Programmable Gate Array (FPGA), or the like.
In order to facilitate the easy operation of the Dock bar of the terminal display screen by both the left hand and the right hand of the user, as an alternative embodiment of the present application, the near field inductor 10 is disposed in the middle of the terminal display screen 20.
The control system for the Dock bar of the terminal display screen disclosed by the embodiment 1 of the invention has the following beneficial effects:
when the near field of the target area detected by the near field sensor changes, the controller controls the Dock bar to be in an unfolded state, and a user can browse information in the Dock bar conveniently. Therefore, according to the scheme, when the fingers of the user are close to the peripheral edge part of the screen of the Dock bar arranged on the terminal display screen, the near field of the target area of the terminal display screen changes, so that the Dock bar is controlled to be automatically unfolded by the controller, the user does not need to click the terminal display screen and pull down the terminal display screen, the operation steps of unfolding the Dock bar by the user are simplified, and the experience of the user is improved.
The middle position of terminal display screen is located to the near field inductor, and the left hand of the user of being convenient for and the comparatively easy operation terminal display screen Dock fence of right hand have further promoted user's experience and have felt.
When the near field inductor adopted hall sensor, hall sensor's sensitivity was higher, whether the near field that can be comparatively accurate and quick detection target area changed to improved the control efficiency who controls the Dock fence, in addition, hall sensor volume is very little, is convenient for install in terminal display screen department. And the excessive space of the terminal display screen is not occupied, and the increase of the whole size of the terminal display screen is avoided.
Example 2
A method for controlling a terminal display screen Dock bar disclosed in embodiment 2 of the present invention is described below with reference to fig. 2(a), fig. 2(b), and fig. 2(c), where fig. 2(a) is a schematic flowchart of a first method for controlling a terminal display screen Dock bar disclosed in embodiment 2 of the present invention, fig. 2(b) is a schematic flowchart of a second method for controlling a terminal display screen Dock bar disclosed in embodiment 2 of the present invention, and fig. 2(c) is a schematic flowchart of a third method for controlling a terminal display screen Dock bar disclosed in embodiment 2 of the present invention. The method may be based on the control system of the Dock bar of the terminal display screen in embodiment 1, and the near-field sensor is arranged at the peripheral part of the screen of the Dock bar of the terminal display screen.
The control method of the Dock bar of the terminal display screen comprises the following steps:
s20: and detecting whether the near field of the target area detected by the near field inductor changes, if so, entering S21, and if not, entering S22.
Specifically, whether the near field of the target area changes or not may be determined by a change in a signal value of an output signal of the near field sensor.
Taking the near-field sensor as an example of the hall sensor, S20 includes:
the output signal of the hall sensor is analyzed.
It is detected whether the voltage amplitude of the output signal exceeds a reference value.
If so, determining that the near field of the target area detected by the Hall sensor changes.
And if not, judging that the near field of the target area detected by the Hall sensor does not change.
As an alternative embodiment of the present invention, the reference value may be a standard voltage amplitude of an electrical signal output when the hall sensor detects a uniform field of the target region. Or the signal value which is up and down floated by 1% can be taken as a reference value by taking the standard voltage amplitude as a reference.
S21: and controlling the Dock bar at the peripheral part of the screen to be in an expanded state.
S22: the Dock bar at the peripheral part of the screen is kept in a hidden state.
In particular, the near field is an inductive field comprising an electrostatic field and a static magnetic field, which for a near field inductor may be chosen as a hall sensor. When no interferent is present in the target area around the display screen of the terminal where the near field sensor is disposed, the field around the near field sensor is uniformly dispersed as shown in fig. 1(b), and when an interferent is present in the target area of the near field sensor, the field around the near field sensor is non-uniformly dispersed as shown in fig. 1 (c). When the near field sensor is a hall sensor, when the field in the target area of the near field sensor is uniformly dispersed as shown in fig. 1(b), the signal value of the output signal of the hall sensor is relatively uniform when the hall sensor continuously detects the field in the target area, and when the field in the target area of the near field sensor is non-uniformly dispersed as shown in fig. 1(c), the signal value of the output signal of the hall sensor is suddenly changed from a normal value when the hall sensor continuously detects the field in the target area, thereby generating fluctuation in a relatively large range.
Further, according to the change rule of the near field change of the target area detected by the Hall sensor and the change rule of the signal value of the continuously output signal, the moving speed of the finger of the user far away from or close to the target area and the finger of the user can be determined, and in addition, the distance between the finger of the user and the Hall sensor can also be determined according to the signal value of the output signal.
It should be noted that, when a finger of a user is located in a target area where a near field sensor can sense a change in the near field, a signal value of an output signal of the hall sensor changes and exceeds a uniform output signal of the near field sensed by the hall sensor, the controller controls the Dock bar to be in the expanded state based on the output signal having a sudden change, after the Dock bar is in the expanded state, the user may operate the Dock bar, and in the process of operating the Dock bar by the user, the finger of the user is also continuously located in the target area, and the Dock bar is also continuously in the expanded state. When the Dock is in the expanded state, the fingers of the user leave the target area immediately, so that the Dock bar can be prevented from being restored to the hidden state along with the fact that the fingers of the user leave the target area, the preset time can be set, the Dock bar can be restored to the hidden state after the actual time when the Dock bar is in the expanded state reaches the preset time, and the user experience sense is prevented from being reduced due to the fact that the user cannot normally operate the Dock bar.
Furthermore, after the Dock bar is in the expanded state through user operation, the condition that the Dock bar occupies system CPU resources for a long time and consumes power for a long time due to the fact that the Dock bar is in the expanded state for a long time is avoided, and the Dock bar is restored to the hidden state when the fingers of the user are far away from the infrared emitting device. As an alternative embodiment of the present application, as shown in fig. 2(b), after S21, the method further includes:
s23: and judging whether the time of the Dock bar in the unfolding state reaches a preset time. If so, the process proceeds to step S24, and if not, the process proceeds to step S25.
S24: the Dock bar is controlled to return to the hidden state.
S25: the control Dock bar continues to be in the expanded state.
Specifically, the predetermined time may be set according to a requirement of a user, and is specifically taken as how much the predetermined time is, and the embodiment of the present invention is not limited herein, wherein in some embodiments of the present invention, the predetermined time may be selected as 60 seconds.
Further, when the time that the Dock bar is in the expanded state reaches a predetermined time, the user may still be operating the Dock bar, so as to avoid that the Dock bar returns to the hidden state in the process of the user operation and the experience of the user is affected, as shown in fig. 2(c), after the time that the Dock bar is in the expanded state reaches the predetermined time, before controlling the Dock bar to continue to be in the hidden state, the method further includes:
s26: and detecting whether the near field of the target area detected by the near field inductor returns to the original state, if so, entering S24, and if not, entering S25.
Specifically, the near field of the target area returning to the original state means that the user's finger is far away from the target area so that the near field of the target area is in the original state (uniform state).
Specifically, as an alternative embodiment of the present application, the target area may be a circular area formed by taking a position where the near-field inductor is located as a center point and taking a predetermined distance as a radius. In order to accurately sense that the target object is close to the near-field inductor and the induction effect of the near-field inductor, the predetermined distance may be 2 cm, and the target object may be a finger.

when the near field of the target area detected by the near field sensor changes, the Dock bar is controlled to be in an unfolded state, and a user can browse information in the Dock bar conveniently. Therefore, according to the scheme, when the fingers of the user are close to the peripheral edge part of the screen of the Dock bar arranged on the terminal display screen, the near field of the target area of the terminal display screen changes, so that the Dock bar is controlled to be automatically unfolded, the user does not need to click the terminal display screen and pull down the terminal display screen, the operation steps of unfolding the Dock bar by the user are simplified, and the experience of the user is improved.
After the fact that the Dock bar is in the expanded state reaches the preset time, the Dock bar is controlled to restore the hidden state, and the situation that the Dock bar occupies system CPU resources for a long time and consumes power for a long time due to the fact that the Dock bar is in the expanded state for a long time is avoided.
When the time that the Dock bar is in the unfolding state reaches the preset time, the Dock bar is controlled to restore the hidden state only when the fingers of the user are far away from the target area, so that the near field of the target area detected by the near-field sensor is restored to the original state, the condition that the Dock bar is restored to the hidden state in the user operation process is avoided, and the experience of the user is further improved.

if yes, controlling the Dock bar to recover to the hidden state;
if not, controlling the Dock bar to be in the expansion state continuously; and is
After the time for judging that the Dock bar is in the expanded state reaches the preset time, before controlling the Dock bar to recover to the hidden state, the method further includes:
detecting whether the near field of the target area detected by the near field inductor is restored to an original state or not;
if yes, entering a step of controlling the Dock bar to recover to the hidden state;
if not, entering the step of controlling the Dock bar to be continuously in the expansion state; and is
The detecting whether the near field of the target area detected by the near field inductor changes comprises:
analyzing an output signal of the near-field inductor;
detecting whether the voltage amplitude of the output signal exceeds a reference value; the reference value is a signal value which is up and down floated by 1% by taking the standard voltage amplitude of an electric signal output when the near-field inductor detects a uniform field of a target region as a reference;
if so, determining that the near field of the target area detected by the near field inductor changes;
if not, determining that the near field of the target area detected by the near field inductor does not change.
