Detailed Description
In order to make the objects, technical features and implementation effects of the present invention clearer, the technical solutions of the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The embodiment provides a method for displaying information on a mobile terminal, which is applied to a mobile terminal with a display window, as shown in fig. 1, and includes:
step 101, displaying a first display content in the display window;
102, acquiring a space signal formed by the movement of a mobile terminal in a space;
103, generating a display adjustment instruction according to the space signal;
and 104, displaying second display content in the display window according to the display adjusting instruction, wherein the first display content is different from the second display content.
By applying the technology provided by the embodiment, the motion track of the mobile terminal is used as the adjustment basis for the information to be displayed, and the multi-step operations such as selection, touch, step-by-step movement and the like are replaced by one-step actions of the user, so that the existing operation mode of the mobile terminal is changed, and the user experience is improved.
In this embodiment of the present invention, when there is one original display content, the first display content and the second display content are different, including: the first display content is a partial area of the original display content; the second display content is another partial area of the original display content; the size of the original display content is larger than that of the display window; or,
the first display content is a partial area of the original display content; enlarging the area of the first display content in the display window after the size of the first display content is enlarged to be used as the second display content; or reducing the first display content and the area around the first display content and located in the original display content to be used as the second display content.
For example, if the mobile terminal supports a digital map function, the original display content is a digital map, and changes in the linear acceleration La and/or the angular acceleration Wa are relied on to change the state of the digital map. When a user needs to look up a specific geographic area on a digital map, assuming that the size of the digital map that the user wants to see is 3000 × 1800 and the display screen of the mobile terminal has only a resolution of 320 × 240, when the user wants to see the entire route, the mobile terminal can only see the entire route on the display screen of 320 × 240, and cannot provide a complete digital map with a resolution of 3000 × 1800, and many details of the map are lost.
The digital map with the resolution of 3000 x 1800 is not moved, only a part of area of the digital map can be displayed on the mobile terminal at the moment, the mobile terminal moves along the direction of a route to be checked, and at the moment, the sensor detects and generates specific numerical values of the linear acceleration La and/or the angular acceleration Wa of the mobile terminal.
The above describes the case where the linear acceleration La and/or the angular acceleration Wa in the acceleration type are/is used as the spatial signal to adjust the second display content in the display window.
Since the complete description of the spatial motion of the mobile terminal requires the detection of 9 degrees of freedom, that is, the XYZ absolute spatial coordinates, the velocity in the XYZ direction, and the rotation in the XYZ three axes, at least 9 independent dimensional data are required to accurately describe the 9 degrees of freedom. All sensors capable of providing extra-dimensional motion information can cooperatively operate, so that the operation precision is improved, and various possible motion data acquisition errors are reduced. In various embodiments of the present invention, however, it is not necessary to measure in all 9 degrees of freedom in describing the spatial movement of the terminal. In this embodiment, as shown in fig. 2, the scaling adjustment according to the spatial movement of the mobile terminal includes:
step 201, receiving a start command, and starting an adjustment function.
Step 202, it is detected that the mobile terminal moves in the space.
In step 203, the sensor calculates displacement and/or movement speed in three directions and/or inclination in three directions, so as to obtain a space signal formed by the movement of the mobile terminal in the space.
And step 204, calculating the scaling multiple according to the displacement in the vertical direction, and putting the corresponding display content into a display cache.
Step 205, zooming the display content in the display cache, i.e. the first display content or a local area thereof.
And step 206, finishing detection, receiving a closing command, and returning to a normal use mode.
In this embodiment, as shown in fig. 3, adjusting display content according to the spatial movement of the mobile terminal includes:
step 301, the adjustment function is turned on.
Step 302, detecting that the mobile terminal moves in the space.
In step 303, the sensor calculates displacement and/or movement speed in three directions and/or inclination in three directions, so as to obtain a spatial signal generated by the movement of the mobile terminal in the space.
And 304, positioning the content to be displayed at the next moment, and putting the corresponding display content into a display cache.
And 305, displaying the display content in the display cache as the current display content in the display screen.
And step 306, ending the detection and returning to the normal use mode.
In the above embodiment, the mobile terminal is usually located in a space and held in a hand of a user, and when the mobile terminal is located on a smooth plane, possible embodiments are as follows: adopt photoelectric sensor to detect mobile terminal's removal, and the space signal that generates specifically includes: and sensing the motion of the mobile terminal on a plane by reflecting light changes or monitoring the movement of texture images acquired by the bottom photoelectric imaging element, and generating a space signal according to the motion.
If a mapping relationship exists between the spatial signal and the display adjustment instruction, generating the display adjustment instruction according to the spatial signal includes, in the mapping relationship: determining spatial signal types, one spatial signal type corresponding to at least one display adjustment instruction; in the spatial signal type, for a spatial signal, a variation parameter of the spatial signal in a unit time is calculated, and the variation parameter is subjected to certain correction and processing and corresponds to one or more specific display adjustment instructions. Specifically, the spatial signals generated correspondingly may be classified according to different movements of the mobile terminal itself in the space, and the following describes different embodiments:
acceleration movement types, including: linear acceleration La, angular acceleration Wa. Wherein, the linear acceleration La describes the acceleration value of the mobile terminal in the linear direction of the space, and the angular acceleration Wa describes the speed of the angle change of the mobile terminal when the space makes a curve motion. For example, the angle that the mobile terminal rotates is obtained within a unit time, for example, 0.5 second, and the average angular velocity within the 0.5 second is calculated and regarded as a stable value. The same can be obtained for the acceleration.
The angular acceleration Wa may also be referred to as rotational movement.
The translation movement type is distinguished from acceleration movement, and translation movement only refers to uniform movement of the mobile terminal. Due to the instability of the mobile terminal, the fine acceleration generated in the moving process can be specifically filtered and corrected. For example, the average velocity of the mobile terminal is calculated over a unit time, e.g., 0.5 seconds, and the average velocity is regarded as a stable value.
And the axial type, namely the mobile terminal moves along a direction perpendicular to the display window to form a space signal, and particularly an axial velocity vector can be formed.
The track type may specifically be a rotation track, an axial track, or a parallel track parallel to a plane in which the mobile terminal is located.
In order to help technicians to further understand the technical solution of the present invention, in this embodiment, a description is given to the generation of the spatial signal, which may be, but is not limited to:
the mobile terminal moves in the space to form a track; acceleration generated by the movement of the mobile terminal in space; a speed direction of the mobile terminal while moving in space; the tilt angle of the mobile terminal in space; at least one of the foregoing.
Wherein, can set up different detecting instrument in mobile terminal, include:
when the mobile terminal moves in the space under the action of an external force, acceleration is generated due to stress, and the accelerometer detects the acceleration to generate a space signal.
The camera is adopted to shoot the reference object at different time points to generate images of different frames, and the motion direction vector of the mobile terminal can be calculated as a space signal according to the difference between the images of different frames, wherein the space signal is specifically the speed direction.
And acquiring an acceleration value of the mobile terminal in a linear direction of a space and acquiring the angle change speed of the mobile terminal in the space during curvilinear motion by adopting a multi-axis gyroscope and/or a multi-axis acceleration sensor. Including but not limited to the following described specific implementations:
acquiring a certain time line acceleration La and an angular acceleration Wa, and corresponding first algorithm logic, and calculating a direction delta Y1 and a distance delta Dis1 of single-step movement of the second display content as a display adjustment instruction, wherein the first algorithm logic in the process comprises the following steps:
△Y1＝Direction1(La，Wa)；
△Dis1＝Distance1(La，Wa)；
that is, there is one Direction first correspondence relationship Direction1() in which the independent variables are the linear acceleration La and the angular acceleration Wa, and the dependent variable is the Direction Δ Y1;
there is a Distance first correspondence relation Distance1() in which the independent variables are the linear acceleration La and the angular acceleration Wa and the dependent variable is the Distance Δ Dis 1;
and the direction first corresponding relation and the distance first corresponding relation are linear, for example:
Δ Y1 ═ k1 La + k2 ═ Wa + b 1; and the number of the first and second groups,
Δ Dis1 ═ k3 La + k4 ═ Wa + b 1; wherein k1, k2, k3 and k4 are all non-zero numbers.
Here, the linear acceleration La and the angular acceleration Wa as independent variables are stable values after correction.
Or,
calculating the moving direction and distance of the image according to the received linear acceleration La in the spatial position adjustment parameter and corresponding second algorithm logic, wherein the second algorithm logic in the process comprises the following steps:
△Y2＝Direction2(La)；
△Dis2＝Distance2(La)；
that is, there is a directional second correspondence relationship in which the independent variable is the linear acceleration La and the dependent variable is Δ Y2;
there is a second distance correspondence in which the independent variable is linear acceleration La and the dependent variable is Δ Dis 2;
and the direction second corresponding relation and the distance second corresponding relation are linear, for example:
Δ Y2 ═ k5 × La + b 2; and the number of the first and second groups,
Δ Dis2 ═ k6 La + b 2; wherein k5 and k6 are both non-zero numbers.
Here, the linear acceleration La as an independent variable is a stable value after correction.
Or,
calculating the moving direction and distance of the image according to the received angular acceleration Wa in the spatial position adjustment parameter and a corresponding third algorithm logic, wherein the third algorithm logic in the process comprises the following steps:
△Y3＝Direction3(Wa)；
△Dis3＝Distance3(Wa)；
that is, there is a directional third correspondence relationship in which the independent variable is the angular acceleration Wa and the dependent variable is Δ Y3;
there is a third correspondence of distance in which the independent variable is the angular acceleration Wa and the dependent variable is Δ Dis 3;
and the third corresponding relation of the direction and the third corresponding relation of the distance are linear, for example:
Δ Y3 ═ k7 × Wa + b 3; and the number of the first and second groups,
Δ Dis3 ═ k8 × Wa + b 3; wherein k7 and k8 are both non-zero numbers.
The angular acceleration Wa as an independent variable is a stable value after correction.
Alternatively, the fourth algorithm logic may be derived from the second algorithm logic and the third algorithm logic, and if both follow a linear correspondence:
there is a direction fourth correspondence relationship in which the independent variables are the linear acceleration La and the angular acceleration Wa, and the dependent variable is Δ Y4;
Δ Y4 ═ Δ Y2 +/Δ Y3 ═ k5 × La + b2) + (k7 × Wa + b 3); namely:
△Y4＝k5*La+k7*Wa+(b2+b3)＝k5*La+k7*Wa+B；
△Dis4＝△Dis2+△Dis3＝k6*La+k8*Wa+B；
here, the linear acceleration La and the angular acceleration Wa as independent variables are stable values after correction.
It can be seen that the fourth correspondence is substantially identical to the first correspondence.
When the trajectory is used as the spatial signal, since the trajectory may specifically be a rotation trajectory, an axial trajectory, or a parallel trajectory parallel to a plane where the mobile terminal is located, different display adjustment instructions need to be set for different trajectories, which specifically includes:
parallel tracks corresponding to the first display adjustment instruction: the virtual plane where the original display content is located is larger than the size of the display window, the original display content keeps static or slightly moves relative to a user, current information in the display window is called as first display content, and when the mobile terminal moves to form a new display adjusting instruction, second display content is displayed.
Rotating the track corresponding to a second display adjustment instruction: the second display adjustment instruction is a display content stabilization instruction. When the mobile terminal rotates in the current plane, the display content is kept in a stable state and does not rotate along with the rotation of the mobile terminal. The same browsing effect can be provided for users with different use habits.
An axial trajectory corresponding to a third display adjustment instruction, the third display adjustment instruction being a zoom instruction; and an axis is arranged, the axis is vertical to the plane of the display window, and when the mobile terminal moves along the direction of the axis, a third display adjustment instruction is formed according to a track formed by the movement. For example, when moving upward, for the zoom-in command, the magnification is proportional to the amount of displacement of the trajectory; when moving downwards, in order to reduce the command, the reduction multiple is in direct proportion to the displacement of the track, and may also be in an exponential relation, for example, the moving speed of a computer mouse pointer may mediate the coefficient of the exponent, control the acceleration, and both zooming and translation may encounter similar problems.
The different tracks correspond to different display adjustment instructions, and the corresponding relationship between the tracks and the display adjustment instructions may be selected, for example, the rotation track does not correspond to the second display adjustment instruction any longer, but corresponds to the third display adjustment instruction. The specific mapping may be equivalent to the first, second, third, and fourth algorithmic logics described.
The method for acquiring the space signal formed by the movement of the mobile terminal in the space further comprises the following steps: when the change of the working mode of the mobile terminal in the space is detected, determining a specific sensor for acquiring a space signal after the change; the number of sensors operating in each operating mode is at least one. In view of the versatility of mobile terminals, a terminal may be used in different operating modes, for example, not only moving in space, but also moving in a horizontal plane, with a slight difference between the two operating modes, in that when in the horizontal plane operating mode, the spatial signal generated by the movement of the mobile terminal in the vertical direction is not detected, ignored or removed. The method specifically comprises the following steps:
in the air working mode, the technical scheme disclosed in the above embodiment may be adopted to obtain the spatial signal, generate a display adjustment instruction according to the spatial signal, and adjust the second display content in the display window. Such as an acceleration sensor.
The horizontal plane operating mode may be based on the technical solutions disclosed in the embodiments of the present application, and may not detect, ignore or remove the spatial signal generated by the movement of the mobile terminal in the vertical direction after the detection, and generate the display adjustment instruction only according to the spatial signal generated by the movement in the horizontal plane, so as to adjust the second display content in the display window. Such as with a photosensor.
When the working mode of the terminal is detected to be changed, a specific sensor for acquiring the spatial signal in the specific working mode needs to be determined, including but not limited to, judging the working mode of the user through a contact sensor arranged on the terminal. For example, when the terminal is detected to be held by a user, the terminal is judged to be in an air mode, and a setting instruction is sent out to enable the acceleration sensor to work; and if the terminal is detected to be pressed by the user, judging that the terminal is in a horizontal plane working mode, and sending a setting instruction to enable the photoelectric sensor to work. The working mode of the user can be judged by other modes or by adopting a mode actively selected by the user to switch the working mode.
In the high-speed working mode, in the corresponding working scene, the operation can be completed only by the low-precision space signal, so that the detection can be completed by adopting the sensor with lower detection precision to generate the space signal. Such as a camera.
In the low-speed operation mode, for example, when the mouse is used as a mouse in a corresponding operation scene, a high-precision spatial signal is required to complete the operation, and therefore, the detection is completed by using a sensor with high detection precision alone, or the detection is performed by using a sensor with low precision, and the sensor with high precision is used again to perform the correction to generate the spatial signal. Such as with an infrared sensor.
When the working mode of the detection terminal is changed, a specific sensor for acquiring the space signal in the specific working mode needs to be determined, including but not limited to, detection by a speedometer arranged on the terminal, for example, when the speed of the detection terminal is greater than a speed threshold value, a setting instruction is sent out to enable a camera to work; and if the speed of the terminal is detected to be less than or equal to a speed threshold value, sending a setting instruction to enable the infrared sensor to work.
Specifically, the sensor is used for detecting the space signal, and the initially detected space signal can be corrected by the sensor itself or by setting a correction algorithm additionally. The detection of the spatial signal can be achieved in different ways, for example, a single sensor can be used, or a dual sensor or even more than three sensors can be used.
For example, changing the relationship between different spatial signals generated in different ways and different display adjustment instructions, the following describes how to acquire spatial signals and generate corresponding display adjustment instructions according to different spatial signals:
and the gyroscope is used for detecting the inclination angle of the mobile terminal to generate a display adjustment instruction, moving the display content in the virtual plane along the inclination direction, and controlling zooming, sidebar calling, scrolling and the like by rotating the mobile terminal.
The accelerometer detects acceleration of three axial directions of XYZ or less, obtains moving speed by integrating time for the first time, and obtains moving distance by integrating time for the second time. If the trajectory is to be obtained, 3 axial displacements are sampled at regular time intervals. But generally use is made of acceleration or velocity directly. Specifically, two accelerometers are installed in opposite directions, and if the accelerometers are interfered by the same noise source, the noise influence can be greatly reduced through methods such as differential calculation.
The camera is used for calculating continuous images collected by the camera, identifying the movement direction/front and back, enabling the display content to correspondingly move, move up and down, move left and right, enlarge and reduce and the like.
Not only does it rely on the same type of sensor to detect movement and generate spatial signals, but different types of sensors can be applied in combination, for example:
accelerometers are combined with cameras, where the accelerometer detects fast position changes more accurately, but can be more affected by hand stability/noise interference for slow changes. The camera is influenced by the refresh rate, so that the trailing blur is difficult to calculate for fast moving imaging, and the slow motion detection is more accurate. The data obtained by the camera is used at low speed, and the accelerometer data is used at high speed, so that more accurate effect is achieved.
The pressure sensor controls single-dimension operation, zooming, page turning, browsing speed and the like, multi-task/multi-webpage switching and file tree level switching by detecting the pressure of a user.
The touch controller and the touch screen application realize the control of each dimension by stroking a specific area.
The infrared sensor and the infrared camera detect the gesture of the infrared LED accessories (such as a mobile phone chain and the like) to realize the three-dimensional control of the content.
Geomagnetic sensors, as well as gyroscopes/accelerometers.
And the photoelectric sensor is limited to be applied on a plane, and the movement of the mobile terminal on the plane is induced through the change of the reflected light, so that the displayed content correspondingly acts.
If more than one sensor is adopted to detect the space signal, without loss of generality, taking two sensors as an example for distinguishing, the two sensors are respectively called as a first sensor and a second sensor, and the technical scheme is as follows:
the mobile terminal moves in space, a first sensor detects a first space signal, and a coarse adjustment instruction is generated according to the first space signal; the second sensor detects a second spatial signal and generates a fine adjustment command according to the second spatial signal.
In this embodiment, the mobile terminal moves in space, the first sensor generates a first space signal according to a trajectory formed by the movement, and generates a coarse adjustment command according to the first space signal. The coarse adjustment instructions cause a coarse adjustment of the second display content in the display window. Specifically, the area of the second display content in the display window may be switched, for example, the second display content may be switched to a different area of the first display content.
The second sensor can detect the moving track or speed of the mobile terminal in the axial direction of the plane where the display window is located as a space signal, and a fine adjustment instruction is generated according to the second space signal. The fine adjustment instruction performs fine adjustment on the second display content in the display window. Specifically, the zoom operation may be performed on a local area in the second display content in the display window, for example, an intersection in the second display content may be enlarged, or a building may be enlarged.
With the technical scheme, the method for displaying information on the mobile terminal is applied to the mobile terminal with the display window, can be realized in different application scenes, and comprises the following steps:
displaying first display content in the display window;
receiving a starting command; detecting an operation of clicking the touch screen; at this point, a function is initiated, specifically representing image movement in an oblique angle;
acquiring a first space state of the mobile terminal according to the starting command; the method comprises the following steps: and obtaining the current terminal inclination angle, such as 30 degrees leftward inclination, where the 30 degrees leftward inclination is the first spatial state.
Forming a space signal according to the first space state, and generating a display adjustment instruction according to the space signal;
and displaying second display content in the display window according to the display adjustment instruction, wherein the first display content is different from the second display content, and specifically, the image moves leftwards.
Accepting a close command, such as re-clicking the touch screen, closes the function.
In the above technical solution, the terminal does not adjust the display content by default in a horizontal situation, and after the terminal is started, the terminal changes a trajectory/state and the like in a space, that is, generates a display adjustment instruction.
In another application scenario, different from the above embodiment, the reference value is required in the process of forming the spatial signal by the terminal, and specifically includes:
displaying first display content in the display window;
receiving a start command, such as clicking a touch screen; at this point, a function is initiated that represents the image movement, in particular, at an oblique angle.
Acquiring a first space state of the mobile terminal according to the starting command; the first spatial state is a reference state; and acquiring the current terminal inclination angle, such as 30 degrees leftward inclination, as a reference value.
Acquiring a second space state of the mobile terminal; obtaining a current terminal inclination angle, such as 20 degrees to the left, as a second value;
forming a space signal according to the first space state and the second space state, which may be a difference between a second value and a reference value;
generating a display adjustment instruction according to the space signal;
and displaying second display content in the display window according to the display adjustment instruction, wherein the first display content and the second display content are different, for example, specifically, the image moves to the right.
And receiving a closing command, such as clicking the touch screen again to close the function.
In the above switching of the operation mode, a G-Sensor is specifically used as the Sensor. Under a relatively stable state of the mobile terminal, the acceleration value transmitted by the G-Sensor is approximately equal to the component of the gravity acceleration on the three axes of x, y and z, so that the three components can be used for judging the inclination posture of the mobile terminal and responding in an application layer of the mobile terminal. The realization process is as follows:
step 501, an initial position is determined. When the G-Sensor is started, the position of the mobile terminal is an initial position, and numerical values on x and y axes are obtained.
Step 502, the posture of the mobile terminal is determined once at regular intervals, such as 50 milliseconds. If the difference between the current value of x or y and the absolute value of the value of x or y at the initial position exceeds a preset threshold value, the mobile terminal is considered to be tilted once, and the tilt direction of the mobile terminal can be known from the positive and negative of the numerical value difference: up, down, left and right.
For example, in the above embodiment, the first spatial state is tilted to the left by 30 degrees as the reference value, and the second spatial state is tilted to the left by 20 degrees as the second value, and although the second spatial state is still tilted to the left, the mobile terminal image should be moved to the right if it is actually changed to the right with respect to the first spatial state.
The application layer responds, step 503. For example: in the application of the browser, when the fact that the mobile terminal tilts towards the positive direction of the x axis is known, a current page is scrolled to the right through a function WebView.
