Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Fig. 1 is a schematic structural diagram of a terminal shown in an embodiment of the present disclosure, and as shown in fig. 1, the terminal 100 includes:
a back shell 101;
a display screen 102 installed in the back case 101 and exposing a display surface outside the back case 101;
the touch panel 103 is stacked on the display screen 102 and used for detecting an acting force acting on the display surface to obtain first detection information;
the sensor 104 is positioned between the display screen 102 and the back shell 101 and is used for detecting acting force acting on the back shell 101 to obtain second detection information;
a processing module 105, connected to the touch panel 103 and the sensor 104, configured to receive the first detection information and the second detection information, and determine a holding posture of the terminal 100 according to the first detection information and the second detection information; the gripping gesture includes: horizontal screen holding and/or vertical screen holding.
In the embodiments of the present disclosure, the terminal may be a mobile phone, a tablet computer, a wearable device, or the like. The terminal includes backshell 101 and display screen 102, and the display surface of display screen 102 exposes outside backshell 101, and display screen 102 and backshell 101 after the installation form an accommodation space, can hold various functional device in the accommodation space, for example camera module, antenna module and audio frequency module etc.. In the embodiment of the present disclosure, if the display surface of the display screen 102 is referred to as a "front surface", the surface on which the back case 101 is located may be referred to as a "back surface".
The terminal further includes a touch panel 103, where the touch panel 103 is stacked on the display screen 102, for example, the touch panel 103 is located on the display screen 102, or the touch panel 103 is disposed inside the display screen 102 as a sensing layer. The touch panel 103 is configured to detect an acting force acting on the display surface to obtain first detection information. The first detection information may include: the coordinate information can also comprise force information of acting force and the like.
The terminal further includes a sensor 104, the sensor 104 is located in an accommodating space formed by the display screen 102 and the back shell 101, for example, the sensor 104 may be disposed on a side of the housing 101b facing away from the display surface of the display screen 102. The sensor 104 may be a pressure or proximity sensor that can detect both proximity and touch events of an object. In the embodiment of the present disclosure, the sensor 104 is used to detect the acting force acting on the back shell 101, and obtain the second detection information. The second detection information may also be coordinate information, or other information characterizing the action position of the acting force, for example, a "0" characterizing the acting force acts on the preset target area, and a "1" characterizing the acting force acts on the non-preset target area.
The terminal further comprises a processing module 104, wherein the processing module 104 is also located in an accommodating space formed by the display screen 102 and the back shell 101, is connected with the touch panel 103 and the sensor 104, and is used for receiving the first detection information and the second detection information and determining a holding posture of the terminal according to the first detection information and the second detection information, and the holding posture comprises horizontal screen holding and vertical screen holding.
The terminal may control the display screen 102 to display in a display mode matching the determined holding posture, for example, switch between a landscape display and a portrait display. In addition, when a motion sensing game is played by the terminal, a corresponding game control can be performed based on the determined holding posture.
In one embodiment, there is a method of determining a grip posture of a terminal based on a gravity sensor. Fig. 2 is an exemplary diagram of detecting a holding posture of a mobile phone by using a gravity sensor, as shown in fig. 2, when a screen of the mobile phone is perpendicular to the ground, a direction of the mobile phone can be recognized more accurately; however, when the mobile phone screen is parallel to the ground, the gravity sensor cannot accurately judge the direction. The gravity sensor judges the horizontal and vertical screen directions according to the components of gravity on the x and y axes, when the mobile phone screen is parallel to the ground, the gravity only has a component on the z axis, and no component on the x and y axes, so the gravity sensor cannot judge whether the mobile phone is a horizontal screen or a vertical screen.
For example, fig. 3 is an exemplary diagram of a user who lies on his back to use a mobile phone, as shown in fig. 3, the mobile phone screen is parallel to the ground, so that the horizontal and vertical screen directions cannot be accurately determined, which may cause an abnormal picture direction. Fig. 4 is an exemplary diagram of a user using a mobile phone while lying on side, and as shown in fig. 4, when the user lies on side, a scene that the mobile phone is a landscape screen relative to the ground but a portrait screen relative to the user may appear, and at this time, a landscape screen picture may be displayed only by means of a gravity sensor. Or, a scene that the mobile phone is vertical relative to the ground but horizontal relative to the user appears, and at the moment, the vertical screen picture can be displayed only by the gravity sensor. The result misjudges the posture of the mobile phone relative to the user, so that the image direction is abnormal.
In another embodiment, whether the mobile phone is a horizontal screen or a vertical screen is distinguished by collecting data of a touch screen when a user holds the mobile phone. For example, when the mobile phone is held by the horizontal screen or the vertical screen, different hand types enable the characteristics of the data of the touch screen to be different, so that the horizontal screen or the vertical screen state of the mobile phone can be distinguished by holding and collecting the data of the touch screen and analyzing the data. However, this method has two problems as follows: 1. the gesture of the mobile phone is judged by a single dimension only by considering the holding characteristic of the palm on the front screen, and in addition, the sufficient contact between the palm of the user and the display screen is required to be detected, for example, the touch area is larger than a certain threshold value, namely, the holding gesture of the user is highly dependent; 2. the judgment is carried out only by means of the touch screen data, the data source is single, and when the touch screen data is interfered, if water stains exist on the screen or the touch screen data is in an environment with large radio frequency signals, misjudgment is easily caused.
In contrast, the present disclosure does not rely solely on data of the touch screen (first detection information detected by the touch panel), but also detects an acting force acting on the back case by a sensor in the terminal to obtain second detection information, and determines the holding posture of the terminal according to the first detection information and the second detection information. By the method, on one hand, data sources are increased, the judgment result of the holding gesture is obtained through comprehensive analysis, misjudgment caused by judgment only by means of single touch screen data is reduced, and the judgment accuracy is improved; on the other hand, the requirement of the contact area of the touch screen when being touched is reduced, and the method is also suitable for the scene that the user uses the mobile phone when lying on side or lying on back, so that the scheme disclosed by the invention is more universal, and the use experience of the user is improved.
In one embodiment, the first detection information includes: information of a first position of an applied force acting on the display surface; the second detection information includes: information characterizing a second position of the force acting on the dorsal shell;
the processing module 105 is configured to determine an action area acting on the display surface according to the information of the first position, determine whether an action force acting on the back shell 101 is located in a preset target area according to the information representing the second position, and determine a holding state of the terminal according to the action area and the preset target area.
In an embodiment, the processing module is configured to determine that the terminal is held in a vertical screen mode when the length of the region of the action region is greater than a length threshold, the action region and the preset target region are located on the same side of the terminal, and the acting force acting on the back shell is not located in the preset target region; and/or when the area length of the action area is smaller than or equal to the length threshold, the action area and the preset target area are positioned on the same side of the terminal, and the acting force acting on the back shell 101 is positioned in the preset target area, the terminal is determined to be held by a transverse screen.
In an embodiment of the present disclosure, the first detection information includes information of a first position of the applied force acting on the display surface. Since the terminal is usually held based on the boundary area when it is held, the first position may be a position on the display screen 102 that is located on the boundary of the display screen 102. After receiving the information of the first position, the processing module 105 may determine an action region acting on the display surface according to the first position, and further determine information such as a region length, a region area, and a region orientation of the action region.
In an embodiment of the present disclosure, the second detection information includes information characterizing a second position of the force acting on the back case 101. As described above, the action force acting on the back cover 101 is represented by "0" in the preset target area, and the action force acting on the back cover 101 is represented by "1" in the non-preset target area. The processing module 105 can determine whether the acting force acting on the back shell 101 is located in the preset target area after receiving the second detection information.
Since the terminal is held, typically based on the contact of the area of the side of the back cover 101 with the user, in one embodiment, the predetermined target area is distributed on the back cover 101 or on the side connecting the back cover 101 and the display screen 102. In the embodiment of the present disclosure, the preset target region may be a local region of the back case 101, for example, a portion located near an edge of the back case 101. The preset target area may also be located on a side of the terminal, which refers to a portion connecting the back case 101 and the display screen 102. It should be noted that the position and size of each preset target area in the present embodiment can be determined according to the size of the terminal and the hand shape characteristic of the user in general.
FIG. 5 is an exemplary graph of the active area length on the display of a cell phone, as shown in FIG. 5, the contact length on the border area of the display is available to the cell phone.
Fig. 6 is an exemplary diagram of the preset target areas on the back of the mobile phone, and as shown in fig. 6, the preset target areas are distributed on four sides of the mobile phone, which are A, B, C, D four areas respectively. The area A and the area D are symmetrically arranged, and the area B and the area C are arranged on different sides in a staggered manner based on the common holding habit of a user.
Fig. 7 is a length example of a grip region, and as shown in fig. 7, the length of the region of action of the force acting on the display screen is L1 and L2, and the grip region is close to the D region.
In the embodiment of the present disclosure, after the processing module 105 determines the area length of the acting area on the display surface according to the first detection information and determines whether the acting force acting on the back shell 101 is located in the preset target area according to the second detection information, that is, after the area length of the acting area is greater than the length threshold, the acting area and the preset target area are located on the same side of the terminal, and when the acting force acting on the back shell 101 is located in the preset target area, it is determined that the terminal is held in a vertical screen mode. It should be noted that, when the acting force acting on the back shell 101 is located in the preset target area, it can be understood that a touch is detected in the preset target area.
In addition, in the embodiment of the present disclosure, the length threshold is preset, and may be adjusted according to actual conditions. For example, the length threshold may be determined by detecting data when a large number of users hold the terminal, thereby presetting a statistical value obtained based on analysis of big data; alternatively, the length threshold may be obtained based on a historical operation of the user of the terminal, in which case, for example, a value obtained based on statistical data of a large number of users may be set in advance and then updated to a value obtained based on a historical operation of the user to which the terminal belongs.
FIG. 8 is a diagram illustrating an exemplary determination of the length of the region of action on the display screen, as shown in FIG. 8, after determining the length of the region of action of the action on the display screen 102 as L1 and L2, L1 and L2 can be compared with L2thresholdA comparison is made, wherein LthresholdIs a length threshold.
In the disclosed embodiments, when both L1 and L2 are greater than LthresholdRegion of action and prognosisIf the target area is located on the same side of the terminal and contact is made on the preset target area, the terminal can be determined to be held in a vertical screen mode.
Fig. 9 is an exemplary diagram of a mobile phone held by a vertical screen, and as shown in fig. 9, when the mobile phone is held by the vertical screen, the contact distance between the palm and the long side of the front surface of the mobile phone is long and the palm is not easy to contact the short side of the back surface. Therefore, when the mobile phone detects that the lengths L1 and L2 of the action area on the display screen are both larger than the length threshold value, the action area is close to the D area, and no contact exists on the A, B, C area and the D area on the back of the mobile phone, the terminal is determined to be held in a vertical screen mode.
In the embodiment of the present disclosure, when the area length of the action area is less than or equal to the length threshold, the action area and the preset target area are located on the same side of the terminal, and the acting force acting on the back shell 101 is not located in the preset target area, the terminal is determined to be held in a landscape mode.
Illustratively, when both L1 and L2 are less than LthresholdIf the action area and the preset target area are located on the same side of the terminal, but the preset target area is not in contact with the action area, the terminal can be determined to be held in a horizontal screen mode.
Fig. 10 is an illustration of a mobile phone held by a horizontal screen, and as shown in fig. 10, when the mobile phone is held by the horizontal screen, the hand shape is generally C-shaped, and the hand of the user has a short contact distance with the long side of the front of the mobile phone and a short contact with the short side of the back of the mobile phone. Therefore, when the mobile phone detects that the lengths L1 and L2 of the action area on the display screen are both smaller than the threshold value, the action area is close to the area D, and the contact exists on the area D, the mobile phone is determined to be held in a transverse screen mode.
It should be noted that, the above-mentioned fig. 9 and fig. 10 both take D end as an example for explanation, and the detection manner of the holding close to a end is similar to the method mentioned in the above-mentioned description of fig. 9 and fig. 10, and the present disclosure is not detailed again.
In one embodiment, the sensor 104 is a Sar sensor, and the terminal further includes:
an antenna 106, located between the display screen 102 and the back shell 101, covering the back shell 101;
the Sar sensor is configured to obtain the second detection information through the antenna 106.
In an embodiment of the present disclosure, the sensor 104 is a Specific absorption rate sensor (Sar sensor). The Sar sensor recognizes both object approach and touch events by detecting a change in capacitance between the antenna 106 and the human hand.
For example, when the Sar sensor does not detect that the capacitance value changes through the antenna 106, second detection information representing that no object approaches or touches the area connected with the antenna 106 is generated; when the Sar sensor detects that the change of the capacitance value is in a first range through the antenna 106, second detection information representing that an object approaches to an area connected with the antenna 106 is generated; when the Sar sensor detects that the change of the capacitance value is in the second range through the antenna 106, second detection information representing that an object touches the area connected with the antenna 106 is generated. In the embodiment of the present disclosure, when it is obtained that no object is approaching or touching in the area to which the antenna 106 is connected, and an object is approaching but not touching, the second detection information may be identified by a number "0"; and when it is obtained that the area to which the antenna 106 is connected is touched by an object, the second detection information may be identified by the number "1".
