First Embodiment
As shown in FIG. 1, a display method is provided in an embodiment of the disclosure. The embodiment of the disclosure will be described in detail in conjunction with the drawings. The display method includes steps 101 to 103 as follows.
In step 101, operation data is detected by a first acquisition unit, while a first part of an output content is displayed on a display unit.
In an embodiment of the disclosure, the displayed content is larger than a display region of the electronic device for implementing the solution of the disclosure, only a part of the displayed content can be displayed in the display region. By performing an operation, the part of the displayed content displayed currently in the display region may be replaced.
The operation corresponding to the operation data is an operation to adjust the displayed content, such as screen scrolling or page turning.
In step 102, first focus data of an object user within a set range watching the output content is acquired by a second acquisition unit, wherein the focus data indicates a position of the display unit corresponding to a focus of the object user.
In an embodiment of the disclosure, there are many methods for determining the first focus data based on the data acquired by the second acquisition unit, such as a method A or B as follows.
In the method A, the second acquisition unit may be a human eye detection engine, and position information of a focus of an eye of a user may be acquired and recorded by the human eye detection engine.
The position information may be acquired as follows. The human eye detection engine obtains image information of an object user, detects an eye image in the image information, compares the obtained image with stored initial images, and determines the position of the focus of the user based on the eye image. The initial images may be an image obtained when the user is instructed to watch different preset positions (such as four corners) by prompt information output, during initialization of the detection engine.
In the method B, the second acquisition unit may be an image acquisition unit array provided in a position corresponding to the position of the display unit. Each acquisition unit in the image acquisition unit array corresponds to a coordinate point in the display unit. The information of the user may be acquired by the image acquisition unit array simultaneously. The information acquired by each acquisition unit is detected, an object acquisition unit detecting the user watching the display unit straightly or directly is determined. The coordinate point corresponding to the object acquisition unit is taken as the position of the focus of the user, and thus the position information of the focus of the eye of the user is determined.
In step 103, a second part of the output content is displayed based on the operation data and the first focus data, wherein the second part is different from the first part.
In an embodiment of the disclosure, the first part and the second part are contents displayed in the display unit under different conditions respectively. There are many cases in which the first part is different from the second part. For example, the first part overlaps the second part partially, or the first part is totally different from the second part (that is to say, the area of the region occupied by the second part is not smaller than the display area of the display unit).
In the method provided in an embodiment of the disclosure, after the operation data is detected by the first acquisition unit (that is, the operation with inertial characteristics is detected), the focus data of the user is further detected, where the focus data indicates a position of a displayed content currently watched by the object user. The first focus data needs to be taken into consideration when the displayed content is adjusted based on the operation data by the device. That is to say, reference needs to be made to the focus data when the displayed content is adjusted in the device, so that the adjusted displayed content is synchronized with the reading or the sight line of the user, thereby preventing the operation of the user from becoming invalid.
Second Embodiment
The range over which the displayed content may be adjusted based on the focus data in conjunction with the operation data of the user, so that the variation of the displayed content is synchronized with the reading speed of the user. For example, coordinates in the screen watched by the human eye is obtained by using the human eye detection technique. When the focus varies in the vertical and/or horizontal direction, and operations varying the displayed content (such as screen scrolling operations, operations through a mouse scroll key and operations through the up key or the down key in the keyboard) are performed by the user, the distance to be scrolled over may be determined based on a series of human eye focuses, thereby adjusting the range of the scrolling operation. The specific implementation may include steps 201 to 205 as follows.
In step 201, operation data is detected by a first acquisition unit, while a first part of an output content is displayed on a display unit.
In step 202, first focus data of an object user within a set range watching the output content is acquired by a second acquisition unit, wherein the focus data indicates a position of the display unit corresponding to a focus of the object user.
In step 203, a first position of the display unit corresponding to the focus of the object user is determined based on the first focus data; and the second part of the output content is displayed based on the first position and the operation data. The second part is different from the first part.
In this embodiment, the difference between the first part and the second part is determined based on the first position. For the same operation data, if the second acquisition unit acquires second focus data different from the first focus data (that is to say, the first position is different from the second position corresponding to the second focus data), the second part corresponding to the first focus data is different from the second part corresponding to the second focus data.
For example, for the document page turning operation, if the first position is at 1⁄4 of the display unit, the displayed content is adjusted by 1⁄4 of a whole page in each page turning operation; and if the first position is at 1⁄2 of the display unit, the displayed content is adjusted by 1⁄2 of the whole page in each page turning operation. In an embodiment of the disclosure, in step 202, the first focus data may be acquired by the second acquisition unit periodically, and the output content is adjusted correspondingly once variation of the focus data, as compared to the previous moment, is detected.
In a specific embodiment, the displaying the second part of the output content, based on the first position and the operation data may include:
A, determining a first distance between the first position and a boundary of the display unit; and
B, displaying the second part of the output content based on the operation data and the distance.
In this embodiment, the first distance may be indicated by a vector. The length of the vector is the length of a line segment between the first position and the second position. The direction of the vector is the direction from the first position to the second position. In a specific instance, if the operation data corresponds to the screen scrolling operation, not only variation of the displayed content may be adjusted not only in the up-down direction, but also in the left-right direction.
The displaying the second part of the output content, based on the operation data and the distance, may include steps b1 to b3 as follows.
In step b1, a first adjustment range corresponding to the first distance is determined based on a preset correspondence between the distance and the adjustment range, wherein the adjustment range indicates a difference between the second part and the first part.
In a specific instance, the correspondence between the distance and the adjustment range may be a directly-proportional relation. That is to say, the larger the distance is, the greater the range of the corresponding adjustment is. For example, if the operation data corresponds to a screen scrolling operation, the larger the distance is, the faster the corresponding screen scrolling is; and if the operation data corresponds to a page turning operation, the larger the distance is, the faster the speed for turning the page correspondingly is.
The difference is used to determine the quantity of the different contents between the first part and the second part.
In step b2, the second part of the content to be displayed is determined based on the first adjustment range and the first part.
In step b3, the second part of the output content is displayed based on the operation data.
In this embodiment, the effect of the operation corresponding to the operation data may be adjusted based on the focus data, thus the displayed content that is adjusted based on the focus data in conjunction with the operation data may be consistent with the variation of the displayed content acceptable to the user, so that the reading efficiency of the user is increased and invalid operations of the user are reduced.
In a specific instance, the user performs the screen scrolling operation to adjust the currently-displayed content, 30% of the content displayed on the display unit is updated in each screen scrolling operation, and the second acquisition unit further acquires second focus data. If the second focus data is the same as the first focus data (that is to say, the first position is the same as the second position corresponding to the second focus data), still 30% of the displayed content is updated in each screen scrolling operation. If the second focus data is different from the first focus data, 35%, for example, of the displayed content may be updated based on a preset rule, to accommodate the updating range of the reading rate of the object user. The data in the above embodiment is only illustrative, and may be adjusted based on the requirement of the user in a specific embodiment, which does not limit the method of the disclosure.
Further, in this embodiment, the updating range of the displayed content may be adjusted based on the distance between the focus of the object user and a boundary of the display unit. In an optional instance, the updated range is in direct proportion to the distance, that is to say, the larger the distance is, the greater the updating range. The smaller the distance between the first focus data and the second focus data, the smaller the difference between the first part and the second part.
In this embodiment, the displayed content that has been read is adjusted to be outside of the display region by the electronic device, based on the focus of the user, so that if the user habitually reads only half page, half page is updated in each page turning operation or each screen scrolling operation, and if the user habitually reads a whole page, a whole page is updated in each page turning operation or each screen scrolling operation. With the method in which the displayed content is adjusted based on the habit of the user, the reading efficiency of the user is improved and the display is adjusted consistent with the reading habit of the user, thereby improving user experience.
Third Embodiment
By using the human eye detection technique, coordinates in the screen watched by the human eye is obtained. When the focus varies in the vertical direction, the content before and after the variation is identified by a display mark, thereby improving the watching efficiency. The specific implementation includes steps 301 to 303 as follows (as shown in FIG. 3).
In step 301, operation data is detected by a first acquisition unit, while a first part of an output content is displayed on a display unit.
In step 302, first focus data of an object user within a set range watching the output content is acquired by a second acquisition unit, wherein the focus data indicates a position of the display unit corresponding to a focus of the object user.
In step 303, a display mark is set based on the first focus data, wherein the display mark distinguishes the second part from the first part; and the second part of the output content and the display mark are displayed based on the operation data, wherein the second part is different from the first part.
The setting a display mark based on the first focus data may include:
determining a third position of the display unit corresponding to the first focus data; and providing the display mark at the third position.
In a specific instance, the display mark may be set by using various methods, such as a method A or B as follows.
In a method A, a first content in a set length is selected by taking a third position as a center, and the display effect of the first content is adjusted to be in a first display state, where the first display state is different from the display effect of a part other than the first content in the display unit.
Alternatively, as desired, the first content may be provided at the tail of the first part, may be provided at the head of the second part, or may be provided at both the tail of the first part and the head of the second part.
In a method B, one mark is added between the first part and the second part. The mark may be a mark capable of distinguishing the first part from the second part, such as a separating line.
In this embodiment, a display mark is provided between the first part and the second part based on the focus data, so that the user distinguishes the second part from the first part based on the display mark. When the content output on the display unit is varied, the user may determine the starting position of the updated content based on the display mark soon, thereby facilitating the user to quickly find the content to watch and improving the reading efficiency of the user.
In the embodiments of the disclosure, the above second and third embodiments may be combined. For example, for the screen scrolling operation, the speed for scrolling the screen may be adjusted using the solution provided in the second embodiment, and the displayed contents during the adjustment are distinguished by using the solution provided in the third embodiment.
