Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In order to provide better visual experience for users, the display screen of the intelligent terminal is getting larger and larger in size. Taking a smart phone as an example, in all current smart phones, the layout and size of a virtual keyboard are unified by default, a screen is automatically paved, and when a user needs personalized layout, switching can be performed only according to the layout specified by a system.
When a user uses a virtual keyboard on a large-screen mobile phone to perform key input, both hands are usually required to operate the mobile phone to ensure that each input method area can be clicked. In many times, the user can only operate with one hand for various reasons, and when the user types with the right hand, the leftmost key is difficult to press, so that the inconvenience of key input greatly affects the user experience. How to meet the requirement of one-hand operation of a user is still a problem to be solved urgently by technical personnel in the field.
Accordingly, the embodiment of the invention provides a keyboard layout method. Fig. 1 is a schematic flowchart of a keyboard layout method according to an embodiment of the present invention, and as shown in fig. 1, the method may be applied to the layout of virtual keyboards in touch screens of various intelligent terminals to achieve an input problem held by a single hand, where the intelligent terminal may be a smart phone, a tablet computer, or the like. The method comprises the following steps:
and step 110, determining a finger sliding track under the single-hand operation of the user.
Specifically, the user naturally slides on the touch screen of the intelligent terminal with a finger in a one-hand operation state, and the intelligent terminal records the natural sliding track of the finger on the touch screen, namely the finger sliding track. Here, the finger sliding track may be formed by coordinates of a plurality of finger touch points, the finger sliding track may be a section of arc line formed by a single sliding of a finger of the user, or may be a plurality of arc lines formed by multiple sliding of a finger of the user, and an end point of the arc line may be an edge of the touch screen, or may be any point in the touch screen, which is not specifically limited in the embodiment of the present invention.
For example, the user holds the smartphone with the right hand and slides naturally on the touch screen with the thumb of the right hand, and the smartphone can obtain the finger sliding trajectory. Here, the user may perform one-handed operation by using either the right hand or the left hand, or may perform a sliding operation by using the thumb or the fingers. It should be noted that the finger that naturally slides on the touch screen when the user operates with one hand is the same finger as the finger that is input by the subsequent key.
And step 120, determining a finger reachable area under the single-hand operation of the user based on the finger sliding track.
Specifically, the finger-reachable region is a region on the touch screen that can be touched by a finger for touching the key for input when the user operates the touch screen with one hand. Through the collected finger sliding tracks, the tracks which can be touched by the user furthest during single-hand operation can be simulated, and then the touch screen is divided into a finger-reachable area and a finger-inaccessible area. Here, the finger reachable region is customized for the finger sliding trajectory of the user, and can completely match the actual situation of the single-hand operation of the user.
Fig. 2 is a schematic diagram of a finger-reachable area provided in an embodiment of the present invention, in fig. 2, a matrix frame is a touch screen, a sector portion filled with oblique lines on the touch screen is the finger-reachable area, an arc line of an edge of the finger-reachable area is determined by a finger sliding track, an edge of the finger-reachable area may be obtained by extending a section of the finger sliding track according to a curvature of the finger sliding track, or an edge of the finger-reachable area may be obtained by fitting a plurality of sections of the finger sliding tracks into an arc line intersecting with an edge of the touch screen, which is not specifically limited in this embodiment of the present invention.
Specifically, after the finger-reachable area is determined, the virtual keyboard can be arranged in the finger-reachable area, so that each key in the virtual keyboard is located at a position where the user can touch the virtual keyboard during one-hand operation, and the problem that the key cannot be touched under one-hand operation due to the fact that a touch screen is too large and the key position exceeds the range where the finger can touch the virtual keyboard is solved.
The method provided by the embodiment of the invention determines the finger reachable area under the single-hand operation of the user based on the finger sliding track, realizes the acquisition of the personalized finger reachable area, and can completely meet the single-hand operation habit of the user. The virtual keyboard is arranged in the finger-reachable area, so that a user can touch all keys in the virtual keyboard during single-hand operation, the input efficiency of the single-hand operation is improved, and the input experience of the single-hand operation is optimized.
Based on the foregoing embodiment, fig. 3 is a schematic diagram of a layout flow of a virtual keyboard according to an embodiment of the present invention, and as shown in fig. 3, in the method, step 130 specifically includes:
and step 131, arranging the input method part of the virtual keyboard in the input method area.
In step 132, the functional portion of the virtual keyboard is laid out in the functional area.
The input method area and the function area form a finger-reachable area.
Specifically, the virtual keyboard may be divided into two parts, an input method part and a function part, wherein the input method part includes each input key, such as 9 keys in a nine-key pinyin input mode, 26 keys in a full-key input mode, and the function part includes each function key, such as an emoji key, an input mode switching key, a voice input key, a candidate punctuation key, and the like. Correspondingly, the finger-reachable area is also divided into an input method area and a function area, wherein the input method area corresponds to the input method part of the virtual keyboard, and the function area corresponds to the function part of the virtual keyboard.
The conventional virtual keyboard is a regular rectangular area with a flat layout, keys are aligned in rows or columns, and a finger-reachable area is a sector area. When the virtual keyboard is arranged in the finger-reachable area, the overall shape of the virtual keyboard can be adjusted in a rectangular mode based on the shape of the finger-reachable area, the virtual keyboard is adjusted to be in a fan-shaped layout mode and arranged in the finger-reachable area, the straight layout of an input method part in the virtual keyboard can be kept, the layout of a function part in the virtual keyboard is only adjusted to adapt to the shape of the finger-reachable area, the input method part in the virtual keyboard can be adjusted according to the radian of an arc at the edge of the finger-reachable area, the input method part is distributed in an arc shape, and after the input method part is arranged in the finger-reachable area, the function part is filled in a blank position of the finger-reachable area.
Preferably, in order to adapt to the input habit of the user, when the input method portions are laid out in the finger-reachable region, the layout of the function portions may be implemented by setting the input method region to a rectangular region or other regular regions adapted to the straight layout, and using an irregular region other than the input method region in the finger-reachable region as a function region, while maintaining the straight layout of the input method portions.
It should be noted that, in the embodiment of the present invention, the execution sequence of step 131 and step 132 is not specifically limited, and step 131 may be executed before step 132, or may be executed after step 132, or may be executed synchronously with step 132.
For example, fig. 4 is a schematic diagram of a layout structure of a virtual keyboard according to an embodiment of the present invention, in fig. 4, a region filled with cross lines is an input method region in a finger-reachable region, 3 regions filled with oblique lines are a functional region 1, a functional region 2, and a functional region 3 in the finger-reachable region, respectively, the input method region is a regular rectangular region for laying input method portions in a straight layout in the virtual keyboard, and the functional region is an irregular region for laying functional portions in the virtual keyboard.
According to the method provided by the embodiment of the invention, the input method part in the flat layout is arranged in the input method area of the finger touch accessible area, and the layout mode of the input method part in the conventional virtual keyboard is reserved as much as possible so as to adapt to the input habit of the user, so that the user can smoothly perform key input when switching to the single-hand operation mode. Meanwhile, the functional part is arranged in the functional area of the finger touch area, so that the basic function of the conventional virtual key is met while the thumb touch area is fully utilized.
Based on any of the above embodiments, fig. 5 is a schematic flowchart of a method for determining an input method region according to an embodiment of the present invention, as shown in fig. 5, in the method, before step 131, the method further includes:
Specifically, the finger sliding track may be approximated to a section of circular arc obtained by drawing a circle with the center of rotation of the finger as the center of the circle and the length of the finger as the radius. Here, the center of rotation of the finger is approximated to be at the finger joint.
When the sliding track of the finger is known, the rotation center of the finger and the length of the finger can be determined according to the principle of finding the circle center and the radius of a known circular arc. Further, the finger rotation center and the finger length can be obtained by the principle that the circle center and the radius can be determined by three points on the circle, and the calculation formula of the finger rotation center is as follows:
the calculation formula of the finger length is as follows:
in the formula, the coordinate of the point O is the coordinate of the center of a circle, OxIs the x-axis coordinate of point O, OyThe coordinate of the Y axis of the point O is any A, B, C three points on the finger sliding track, and the coordinate of the three points is recorded as (A)x,k，Ay,k)、(Bx,k，By,k) And (C)x,k，Cy,k) Wherein k is the group number of the finger sliding track, and n is the group number of the finger sliding track.
Here, preset finger inclination angle is used for representing the user and holding intelligent terminal in the one hand, and when the finger was placed naturally on touch screen, the inclination of finger. Preferably, the preset finger inclination angle may be 45 °.
After the finger rotation center and the finger length are determined, a circle is made by taking the finger rotation center as the center of the circle and the finger length as the radius, the ray with the finger rotation center as the end point and the preset finger inclination angle as the direction is taken, and the intersection point of the circle and the ray is taken as the end point of the input method area. The specific calculation formula is as follows:
Mx＝Ox-Rcosθ
My＝Oy-Rsinθ
in the formula, MxAnd MyThe coordinates of the input method area end point M on the x axis and the y axis are respectively, and theta is a preset finger inclination angle.
And step 1303, determining the input method area in the finger-reachable area based on the end point of the input method area and the rotation center of the finger.
Specifically, after the input method region end points are determined, the input method region end points and the finger rotation center are taken as two diagonal end points of the input method region, so that the input method region is determined in the finger-reachable region. It should be noted that, according to the human engineering, when the user holds the smart terminal with one hand, the finger rotation center is usually located on the side of the touch screen.
For example, fig. 6 is a schematic diagram of an input method area according to an embodiment of the present invention, in fig. 6, O is a finger rotation center, R is a finger length, θ is a preset finger tilt angle, M is an input method area end point, and a box filled with a cross line is an input method area end point determined based on M and O.
According to the method provided by the embodiment of the invention, the input method area is determined based on the finger rotation center, the finger length and the preset finger inclination angle, so that the input method part is arranged at the position closest to the finger joint, the position is the most convenient and comfortable position in ergonomics, and the portability and comfort of single-hand input can be improved.
Based on any embodiment, the method further includes, after the step 131:
step 141, adjusting the size of a response area corresponding to each key in the input method area in the input method part based on the key information of the user; the user key information includes at least one of a key velocity, a key heat, and a click probability of each key.
Specifically, in the user key information, the key speed of each key is the speed of each key clicked by the user. For any key, the key speed can be represented as a time interval between the time when the user clicks the previous key and the time when the user clicks the key, and the smaller the time interval, the faster the key speed is, which means that the user is easier to click the key. The larger the time interval, the slower the key speed, indicating that the user is more difficult to click on the key. Generally, the key speed is related to the arrangement positions of the keys, and the farther the keys are arranged, the larger the finger moving distance is, and the slower the key speed is. In addition, when the keys are arranged close to the edge, the finger needs to be bent when clicking the keys, and the key speed is slowed down.
The key heat of each key is the frequency of clicking each key by the user within the preset time, and the higher the frequency is, the higher the key heat is, the greater the possibility of clicking the key by the user is.
The click probability of each key is the predicted probability of each key clicked by the user at the moment, and the click probability can be predicted through the text content input by the user. There are many methods for predicting the click probability, for example, the click probability can be predicted based on a hidden markov model (HMM model), where the HMM model is one of input method decoding models based on an N-Gram language model, and can be used to find a chinese character string W that best represents a string of pinyin strings P, and a mathematical language is used to describe, i.e., maximize the conditional probability, and corresponds to the following formula:
in the above formula, Pr (W) represents the degree of smoothness of the Chinese character string, and is usually calculated by using an N-Gram language model (or other language models), and Pr (P | W) is the probability that the input pinyin string is P when the Chinese character string W is displayed, and can be decomposed into the successive multiplication II of the probabilities of the pinyin strings corresponding to each Chinese character in the Chinese character stringiPr(pi|wi) Wherein p isiFor each individual character corresponding phonetic string, wiFor each individual character, subscript i corresponds to each individual character, Pr (p), in the Chinese character stringi|wi) The probability of each pinyin string corresponding to a single character. The maximum conditional probability is calculated, and details are not repeated in the embodiment of the present invention.
The user key information may be any one or more of the key speed, the key heat and the click probability of each key, and the size of the corresponding response area of each key in the input method area may be preset or dynamically adjusted based on the user key information. Here, any key corresponds to a response area in the input method area, and when the coordinate clicked by the user is located in any response area, it is determined that the user clicks the key corresponding to the response area.
For example, when the user key information includes the key speed of each key, the size of the key response area with low key speed can be correspondingly increased; when the key information of the user comprises the key heat of each key, the size of a key response area with high key heat can be correspondingly increased; when the user key information contains the click probability of each key, the size of the key response area with high click probability can be correspondingly increased, and through the operation, the user can more easily click the key which is difficult to click originally due to long distance, or the key with high heat and high click probability.
Based on any of the above embodiments, in the method, step 141 specifically includes: determining the weight of each key in the input method part based on the key information of the user; and determining the size of the corresponding response area of each key in the input method area based on the weight of each key and the size of the input method area.
Specifically, the weight of each key is used to reflect the size of the response area occupied by the key in the input method area, and the higher the occupancy ratio is, the larger the corresponding response area is. The determination of the weight is determined based on the user key information, for example, the ratio of the average time interval of any key to the sum of the average time intervals of each key may be used as the weight of the key, or the ratio of the click probability of any key to the sum of the click probabilities of each key may be used as the weight of the key. Here, the average time interval is used to characterize the key speed of the key press.
The area of the response region of each key can be determined according to the weight of each key and the area of the input method region, and on the basis, the width and the height of the input method region and the arrangement position of each key in the input method region are combined to further determine the width and the height of each key, so that the adjustment of the response region of each key is directly performed according to the width and the height of the key under the condition of meeting the straight layout rule of the input method region. Further, in the pinyin nine-key input mode, the size of the corresponding response area of each key in the input method area may be determined by combining the following formula:
wherein m and n are positive integers of 3 or less, and represent the number of rows and columns, respectively, and amn、bmnAnd tmnRespectively the width, height and interval time of the mth row and nth column keys, XMAnd YMThe width and height of the input method area are represented by the x-axis and y-axis coordinates of the end point M in the O point coordinate system.
Fig. 7 is a schematic diagram of key setting of an input method area according to an embodiment of the present invention, in fig. 7, points O and M are two end points of the input method area, and the size of a response area corresponding to 9 keys in the input method area is determined according to a key speed, that is, a box in the diagram. It should be noted that in the input method area, gaps between the response areas of the keys are negligible and may not be remembered, and the gaps are actually small, so that the calculation of the size and the position of the response areas of the keys is not affected.
For another example, the ratio of the sum of the click probability of any key and the click probability of each key may be used as the weight of the key, and the area of the response region of each key may be determined based on the weight of each key and the area of the input method region. In the pinyin nine-key input mode, the size of the corresponding response area of each key in the input method area can be determined by combining the following formula:
in the formula, PrmnIs the click probability of the mth row and nth column keys, Pr11+Pr12+…+Pr33＝1。
According to the length and the width of each key response area, the position coordinates of four corner points of each key response area in a coordinate system with the O point as the origin can be determined. For example, fig. 8 is a schematic diagram of key arrangement of an input method area according to another embodiment of the present invention, and in fig. 8, the coordinates of the corner point position at the lower right corner of the key with the number 13 are (0, b)33+b23) The angular point position coordinate of the upper right corner is (0, b)33+b23+b13)。
According to any of the above embodiments, the method further includes, after the step 132:
step 142, based on the current input information, adjusting the corresponding response area of each function key in the function area in the function part; the current input information includes a current input scene and/or current on-screen text.
Specifically, in the application process of the virtual keyboard, the functional part of the virtual keyboard can be adjusted according to the current input scene. Here, the current input scenario may be a social scenario, a document editing scenario, or the like, and the current input scenario may be determined by obtaining package name information of the current application, and the package name information may be obtained from input box information when the virtual keyboard pops up, which is not specifically limited in this embodiment of the present invention. For example, when the entry information is com.tenent.mm (WeChat) or com.tenent.mobileqq (QQ), it is determined that the current input scene is a social scene. In addition, the functional part of the virtual keyboard can be adjusted according to the current on-screen text, or the functional part can be adjusted by combining the current input scene and the current on-screen text.
The function part of the virtual keyboard comprises a plurality of function keys, and the size, position, sorting and other characteristics of the corresponding area of each function key in the function area are associated with the current input information, for example, in a social scene, the function keys related to expressions can be preferentially recommended, and the function keys related to the expressions are sorted according to the clicking popularity, so that a user can conveniently click the most desired expression. For another example, if the user inputs "happy" text, the function key associated with "happy", for example, the function key corresponding to the expression associated with "happy" may be determined by keyword matching, and if there are a plurality of associated function keys, the higher the matching degree is, the larger the area of the response region is, and the position is further forward.
According to the method provided by the embodiment of the invention, the response area of the function key in the function area is adjusted based on the current input scene, so that the adaptability of the virtual keyboard function part to the corresponding input scene can be improved, and a user can click the function key to be clicked more easily.
Based on any of the above embodiments, in this method, step 142 specifically includes: determining function recommendation weight of each function key in a function part corresponding to the current input information; and adjusting the size and/or the sequencing of the corresponding response area of each function key in the function area based on the function recommendation weight of each function key.
Specifically, each function key corresponds to a function recommendation weight, and the function recommendation weight is used for representing the importance degree of the function key in the function part. The function recommendation weights of different function keys may be set in advance for different input scenarios. For example, in a social scenario, the function recommendation weight of the expression-related function key is higher, and in a document editing scenario, the function recommendation weight of the expression-related function key is lower.
After determining the function recommendation weight of each function key, the corresponding response region of each function key in the function region may be correspondingly adjusted according to the function recommendation weight of each function key, where the adjustment of the response region includes adjustment of the size and/or the position of the response region. The higher the function recommendation weight of the function key is, the larger the area of the response region occupied by the function key in the function region is, and the more the position is, and the smaller the function recommendation weight is, the smaller the area of the response region occupied by the function key in the function region is, and the more the position is.
For example, the area of the response region of the function key can be expressed by the following formula:
Sn＝Smin*Cn/Cmin
in the formula, SnArea of response region for nth function key, SminArea of response region of function key being minimum, CnRecommending weight for the function of the nth function key, specifically expressed as the click frequency of the nth function key in a preset period, CminAnd recommending the weight for the minimum function, wherein the weight is expressed as the minimum value of the clicking frequency of all the function keys in a preset period. Thus, the response area of the nth function key may be the product of the ratio of the function recommendation weight of the function key to the minimum function recommendation weight and the minimum response area.
For another example, the method may perform keyword matching on a top screen text input by the user with the input method local resource file library, extract a function matched with the top screen text from the input method local resource file library, determine a corresponding function key, increase a function recommendation weight of the corresponding function key, and preferentially display a response region corresponding to the function key in the function region, so that the user can click the function key.
According to the method provided by the embodiment of the invention, the adjustment of the function part is carried out based on the function recommendation weight, so that the flexibility of the virtual keyboard in the input process is enhanced, and the user experience is optimized.
