FIG. 1 a is a flowchart of a method for displaying a document according to an example embodiment of the present disclosure. The method may be implemented in a terminal device such as the device 800. For example, the method may be implemented as a set of instructions stored in the memory 804 of the device 800 and may be executed by the processor 820 of the device 800. The method may include the following steps:

In step 101, when a target document is displayed on a screen of a terminal device, detecting a displacement of the terminal device and when such displacement is detected, determining a direction of the displacement.

In step 102, translating the target document on the screen according to the direction of the displacement.

According to embodiments of the present disclosure, in a state where a target document is displayed on its screen, when the terminal device detects that the screen is subjected to displacement, the terminal may determine a direction of the displacement, and translate (i.e., move) the target document on the screen according to the direction of the displacement. In this way, terminal device may display different regions of the target document on the screen when its user moves the mobile terminal device around.

FIG. 1 b is a flowchart of a method for displaying a target document according to an example embodiment of the present disclosure. The method may be implemented in a terminal device such as the device 800. The device 800 may be a mobile phone, a tablet computer, or other mobile terminals. For example, the method may be implemented as a set of instructions stored in the memory 804 of the device 800 and may be executed by the processor 820 of the device 800. The target document may be a document saved in the terminal device or downloaded from a remote server, comprising displayable content, such as a picture, a POWERPOINT™ document, or other type of document, or the like. For illustration purpose, in this embodiment, the terminal device is described as a mobile phone and the target document is described as a picture. The method may include the following steps:

In step 101, when a target document is displayed on a screen of a terminal device, detecting a displacement of the terminal device and when such displacement is detected, determining a direction of the displacement.

In the embodiment, the size of the target document may exceed the size of the screen. For example, the target document may be a photo that is taken by full-view photographing or a photo or document displayed after being zoomed in.

In implementation, a user may install an application program for browsing pictures on the terminal device. When the user needs to browse a picture (i.e., the target document), the user may start the application program, and click an icon corresponding to the picture in a picture list provided by the application program, such that the picture is displayed on the screen of the terminal device. The size of the picture may be greater than the size of the screen. In this way, only a part of the picture may be displayed on the screen. When the user desires to view other parts of the picture which is not displayed on the screen, the user may do so by moving the terminal device. In this case, the terminal device may detect a signal sent by a corresponding sensor (for example, a gyroscope, an acceleration sensor, or the like) therein, and thus determine that the terminal device is subjected to a displacement. In this way, the terminal device may further determine the direction of the displacement. For example, when the user opens a full-view photograph on the terminal device, and in browsing the full-view photograph, the user moves the terminal device to the right, then the terminal device may detect that it is subjected to a displacement, and may further determine that the direction of the displacement is towards the right.

According to an example embodiment, the terminal device may only determine a direction of a component of the displacement along a plane where the screen is located; and correspondingly the process in step 101 may further include step 104: when the target document is displayed on a screen of a terminal device, detecting a displacement of the terminal device. When such displacement is detected, determining a direction of a component of the displacement along a plane where the screen of the terminal device is located as a first direction.

In implementation, instead of moving the terminal device exactly within the plane where the screen is located, the user may move the terminal device in any direction, for example, moving the terminal device towards the upper right direction of the screen. Upon detecting that the terminal device is subjected to the displacement, the terminal device may determine, according to a signal from the sensor, the direction of the component of the displacement along the plane where the screen is located. For example, in a case where the user holds and moves the terminal device to the upper right direction of the screen, upon detecting that the terminal device is subjected to displacement, the terminal device may determine that the direction of the component of the displacement along the plane where the screen is located is a direction towards the right. For example, as shown in FIG. 1c, in a 3-dimensional space defined by x-y-z axis, the screen of the terminal device 202 may be in the x-y plan, which mathematically is expressed by a vector i along the z axis. The user of the terminal device may move the terminal device with a displacement of d 45 degree towards up right direction within the x-z plane. The terminal device may detect the displacement and determine that the displacement has a vector component d1 pointing towards right along the x axis.

According to an example embodiment, the terminal device may also acquire a distance of the component of the displacement along the plane from where the screen is located; and correspondingly the process in step 101 may further include step 106: when the target document is displayed on a screen of a terminal device, detecting a displacement of the terminal device. When such displacement is detected, determining a direction of a component of the displacement along a plane where the screen is located as a first direction and determining a distance of the component of the displacement along the plane where the screen is located (e.g., determining a distance along) as a first distance.

In implementation, upon detecting that the terminal device is subjected to displacement, the terminal device may determine the direction of the component of the displacement along the plane where the screen is located and determine the distance of the component of the displacement along the plane where the screen is located. For example, as shown in FIG. 1c, when the user holds the terminal device and moves it by d=1.414 cm and 45 degree to the upper right direction of the screen, upon detecting that the terminal device is subjected to displacement, the terminal device may determine that the direction of the component of the displacement along the plane where the screen is located is a direction towards the right, and the distance of the component of the displacement along the plane where the screen is located is d1=d×cos(45°)=1 cm.

According to an example embodiment, before it is detected that the terminal device is subjected to displacement, the terminal device may enable a sensor configured to detect displacement of the terminal device when displaying an image having a large size; and correspondingly, prior to step 101, the terminal device may perform step 108: when the terminal device detects a full size of the target document displayed on the screen exceeds a size of the screen, enabling a sensor configured to detect displacement of the screen.

In implementation, when the terminal device detects that a picture is displayed on the screen thereof, the terminal device may detect the size of the picture, and compare the size of the picture with the size of the screen. If the size of the picture is greater than the size of the screen, the terminal device may enable the sensor (for example, a gyroscope, an acceleration sensor, or the like), to detect information regarding the displacement of the terminal device. If the size of the picture is less than the size of the screen, the terminal device keeps the sensor disabled. For example, when the user opens a picture on the terminal device, the terminal device displays the picture in a default size, and when the terminal device detects that the default size of the picture does not exceed the size of the screen, the terminal device does not enable the sensor. If the user zooms in the displayed picture, the terminal device may detect the size of the zoomed-in picture. When the terminal device detects that the size of the picture exceeds the size of the screen, the terminal device may enable the sensor. In this way, power consumption of the terminal device may be reduced.

According to an example embodiment, the terminal device may provide a plurality of display control functions to its user, for example, a document translation function and a document zooming function. Hence, the terminal device may perform the process in this procedure only in a state where the document translation function is enabled. Correspondingly, step 101 may subject to a precondition, such as enabling a translation function of the terminal device. For example, step 104 may further include: when the target document is displayed on a screen of a terminal device and the document translation function is enabled, when the target document is displayed on a screen of a terminal device, detecting a displacement of the terminal device. When such displacement is detected, determining a direction of a component of the displacement along a plane where the screen of the terminal device is located as a first direction.

In implementation, in the above application program, both the document translation function and the document zooming function may be enabled, and manners for enabling these two functions may be provided. For example, the document zooming function may be set as enabled when a touch signal is generated on the screen, and correspondingly, the document translation function may be enabled when no touch signal is generated on the screen. When the user desires to translate the picture, the user may keep his or her finger away from touching the screen. In this way, the terminal device detects no touch signal on the screen, and thus enables the document translation function. When the user holds the terminal device and moves it, the terminal device may determine the direction of the component of the displacement along the plane where the screen is located upon detecting that the terminal device is subjected to displacement. For example, if the user does not contact the screen, the terminal device detects no touch signal on the corresponding screen, and thus enables the document translation function; and when the user holds the terminal device and moves it towards the upper right direction, the terminal device may determine that the direction of the component of the displacement along the plane where the screen is located is a direction towards the right.

The user may also use other means to enable the displacement detection function in terminal device. For example, the terminal device may provide a physical hotkey or button or a virtual hotkey or button on the screen. When the user presses the button, the terminal device may enable the sensor to detect the displacement as described above.

In step 102, the target document is translated on the screen according to the direction of the displacement.

For example, upon determining the direction of the displacement, the terminal device may translate the picture on the screen in a direction opposite to the direction of the displacement according to a preset displacement speed, and cease translating the picture on the screen when the terminal device detects that the displacement of the screen ceases.

According to an example embodiment, when the direction of the component of the displacement along the plane where the screen is located is determined as the first direction, the process in step 102 may include step 112: translating the target document on the screen in a direction opposite to the first direction.

For example, upon determining the direction of the component of the displacement along the plane where the screen is located as the first direction, the terminal device may translate the picture on the screen in a direction opposite to the first direction. For example, as illustrated in FIG. 2, upon determining that the direction of the component d1 of the displacement along the x-y plane where the screen is located is a direction towards the right along the x axis, the terminal device translates the picture on the screen to the left to generate a visual effect that the picture remains stationary and the user is observing the target document through a window of the screen size by moving the window over the picture at certain speed.

According to an example embodiment, a condition for ceasing the translation may be defined; and correspondingly, the process in step 102 may include step 114: when the terminal device detects that a boundary of the target document in the first direction coincides with a boundary of the screen in the first direction, ceasing translating the target document.

For example, upon determining the direction of the component of the displacement along the plane where the screen is located as the first direction, the terminal device may translate the picture on the screen in a direction opposite to the first direction, until the boundary of the picture in the first direction coincides with the boundary of the screen in the first direction. For example, if the direction of the component of the displacement along the plane where the screen is located is determined as a direction towards the right, the terminal device translates the picture on the screen to the left, until the right boundary of the picture coincides with the right boundary of the screen.

According to an example embodiment, in a case where the distance of the component of the displacement along the first direction as the first distance; and correspondingly, the process in step 102 may include 116: translating the target document on the screen in a direction opposite to the first direction and for a distance according to the first distance.

For example, the terminal device may be preset with a linear relationship (for example, the translation distance is 1.5 or 2 times of the first distance, or the like) between the translation distance of the picture and the first distance. Upon determining the direction of the component of the displacement along the plane where the screen is located as the first direction and determining the distance of the component of the displacement along the plane where the screen is located as the first distance, the terminal device translates the picture in a direction opposite to the first direction, and the translation distance is a distance of the first distance subjected to a linear transformation. For example, if a linear relationship between the translation distance and the first distance is 2:1, upon determining that the direction of the component of the displacement along the plane where the screen is located is a direction towards the right, and the distance of the component of the displacement along the plane where the screen is located is 1 cm, the terminal device translates the picture displayed on the screen to the left by 2 cm.

In the embodiment, corresponding to the document translation function, the terminal device may also provide a document zooming function; and correspondingly, in a state where the document zooming function is enabled, the terminal device may perform the following steps.

In step 118, when the terminal device is displaying a target document on its screen and a document zooming function is enabled, when the terminal device detects that the screen is subjected to displacement, determining a direction of a component of the displacement perpendicular to the screen as a second direction.

For example, in the above application program, both the document translation function and the document zooming function may be provided, and manners for enabling these two functions may be provided. For example, the target zooming function may be set as enabled when a touch signal is generated on the screen, and correspondingly the document translation function may be set as enabled when no touch signal is generated on the screen. The user may also use other means to enable the displacement detection function in terminal device. For example, the terminal device may provide a physical hotkey or button or a virtual hotkey or button on the screen. When the user presses the button, the terminal device may enable the sensor to detect the displacement.

When the user desires to zoom in or zoom out the picture, the user may touch the screen with his or her finger. In this way, the terminal device may detect a touch signal on the screen, and thus enable the document zooming function. When the user holds the terminal device and moves it, the terminal device may determine the direction of the component of the displacement perpendicular to the screen upon detecting that the terminal device is subjected to displacement. For example, as shown in FIG. 1c, when the user touches the screen with his or her finger, the terminal device may detect a touch signal on the corresponding screen, and then enables the document zooming function; when the user holds the terminal device and moves it towards the upper right direction of the screen with a displacement vector d, the terminal device may determine that the direction of the component d2 of the displacement perpendicular to the screen is a forward direction of the screen upon detecting that the terminal device is subjected to displacement d.

According to an example embodiment, the terminal device may determine how to zoom the picture with reference to the direction and distance of the component of the displacement perpendicular to the screen; and correspondingly, the process in step 118 may include step 120: in a state where a target document is displayed on the screen and the document zooming function is enabled, when it is detected that the screen is subjected to displacement, determining a direction of a component of the displacement perpendicular to the screen as a second direction, and determining a distance of the component of the displacement perpendicular to the screen as a second distance.

For example, in a state where the document zooming function is enabled, upon detecting that the terminal device is subjected to displacement, the terminal device may determine the direction (i.e., the second direction) of the component of the displacement perpendicular to the screen, and the distance of the component of the displacement perpendicular to the screen (i.e., the second distance). For example, as shown in FIG. 1c when the user holds the terminal device and moves it by 1.414 cm and 45 degree to the upper right direction of the screen, upon detecting that the terminal device is subjected to displacement, the terminal device may determine that the direction of the component of the displacement perpendicular to the screen is a forward direction of the screen, and the distance of the component of the displacement perpendicular screen is d1=d×sin(45°)=1 cm.

In step 122, the displayed target document is zoomed according to the second direction.

For example, the terminal device may preset a zooming factor for the zooming process; and in a state where the document zooming function is enabled, upon determining the direction of the component of the displacement perpendicular to the screen as the second direction, the terminal device zooms in or zooms out the picture according to the preset zooming factor, as illustrated in FIG. 3. For example, if the terminal device presets a zooming factor of the size of the zoomed-in picture to the size of the original picture as 3:1, and presets a zooming factor of the size of the zoomed-out picture to the size of the original picture as 1:4, the terminal device may zoom in or zoom out the picture according to the preset zooming factor.

According to an example embodiment, in a case where the direction of the component of the displacement perpendicular to the screen is determined as the second direction, the terminal device may define a corresponding relationship between the second direction and the zooming process; and correspondingly, the process in step 2 may be: zooming in the target document if the second direction is a forward direction (or upward direction) of the screen, and zooming out the target document if the second direction is a backward direction (or downward direction) of the screen.

According to an example embodiment, in a case where the distance of the component of the displacement perpendicular to the screen is determined as the second distance, the process in step 122 may include step 124: determining a zooming factor corresponding to the second direction and the second distance according to a pre-stored corresponding relationship among directions, distances and zooming factors; and zooming the displayed target document according to the determined zooming factor.

For example, the terminal device may preset a corresponding relationship among directions, distances and zooming factors. In the corresponding relationship, if the direction of the component of the displacement perpendicular to the screen is the forward direction of the screen, the distance and the zooming factor are of a first linear relationship. For example, the first linear relationship may be that a zoom-in factor is increased by 0.5 each time the distance of the component of the displacement perpendicular to the screen is increased by 1 cm. In the corresponding relationship, if the direction of the component of the displacement perpendicular to the screen is the backward direction of the screen, the distance and the zooming factor are of a second linear relationship. For example, the second linear relationship may be that a zoom-out factor is reduced by 0.01 each time the distance of the component of the displacement perpendicular to the screen is increased by 1 cm.

Upon determining that the direction of the component of the displacement perpendicular to the screen as the second direction, and determining that the distance of the component of the displacement perpendicular to the screen as the second distance, the terminal device may determine a linear relationship (the first linear relationship or the second linear relationship) corresponding to the second direction, and hence further determine a zooming factor according to the second distance and the corresponding linear relationship thereof. For example, upon determining that the direction of the component of the displacement perpendicular to the screen is the forward direction of the screen, the terminal device may determine that a linear relationship corresponding to the direction is the first linear relationship. In this case, if the distance of the component of the displacement perpendicular to the screen is 1 cm, the zoom-in factor is 1.5; and if the distance of the component of the displacement perpendicular to the screen is 2 cm, the zoom-in factor is 2. Upon determining that the direction of the component of the displacement perpendicular to the screen is the backward direction of the screen, the terminal device may determine that a linear relationship corresponding to the direction is the second linear relationship. In this case, if the distance of the component of the displacement perpendicular to the screen is 1 cm, the zoom-out factor is 0.99; and if the distance of the component of the displacement perpendicular to the screen is 2 cm, the zoom-out factor is 0.98.

Accordingly, the combination of the displacement and the zooming creates a visual effect that the displayed target document remains stationary behind a screen of the terminal device and the user is observing the target document through a window of the screen size by moving forward and/or backward.

According to embodiments of the present disclosure, in a state where a target document is displayed on a screen, when it is detected that the screen is subjected to displacement, a direction of the displacement is determined, and the target document is translated on the screen according to the direction of the displacement. In this way, different regions of the target document may be displayed on the screen by moving the terminal device.

The device may be a mobile phone, a tablet computer, or other mobile terminals. The device may include a determining module 410 and a processing module 420.

The determining module 410 is configured to: in a state where a target document is displayed on a screen, when it is detected that the screen is subjected to displacement, determine a direction of the displacement.

According to an example embodiment, the processing module 420 is configured to: when it is detected that a boundary of the target document in the first direction coincides with a boundary of the screen in the first direction, cease translating the target document.
