Description

Method and device for information input

Technical field

The present application relates to the field of information technology, and in particular, to a method and an apparatus for inputting information.

Background technique

At present, with the emergence of various smart devices and the maturity of technologies such as somatosensory control, virtual reality (VR), and augmented reality (AR), the means for users to input information on devices is no longer limited. Use a physical keyboard and touch screen to enter information.

For example, when a user uses a VR helmet, the VR helmet can project a virtual keyboard and a cursor in front of the user, and the user can select the information to be input on the virtual keyboard by moving the cursor. Alternatively, the virtual keyboard is displayed on the smart TV, and the user controls the cursor to move on the virtual keyboard through the remote control button, selects the information to be input, and the like.

Specifically, the operation when inputting information through the virtual keyboard can be divided into two steps of moving and selecting two steps, that is, moving the cursor to a virtual button, and selecting to input information corresponding to the virtual button.

For mobile operations, it is usually divided into two categories according to whether the cursor can move freely. One type is that the cursor can move freely at any position of the virtual keyboard, as shown in Figure 1a, and the other is cursor attached and virtual keyboard. On a virtual button, when moving the cursor, the cursor can only move to another adjacent virtual button, as shown in Figure 1b. The dotted line shown in FIG. 1a is a moving track of the circular cursor on the virtual keyboard, each transparent circle represents the historical position of the cursor, and the opaque circle represents the current position of the cursor. In Fig. 1b, the shape of the cursor is adaptive to the boundary shape of the virtual button to which it is attached, that is, the closed mark displayed on the outer edge of the virtual key, and the cursor can only move between the virtual keys step by step. Wherein, each arrow indicates the direction in which the cursor moves, the closed mark of the solid line indicates the current position of the cursor, and the closed mark of the dotted line indicates the historical position of the cursor.

The selection operation is generally set in advance. When the user is selected to perform the selection operation, the information corresponding to the virtual button at the position of the cursor is input. Common selections include: click, pause, swipe, and more. For example, when it is detected that a user clicks a button of a controller (eg, mouse, handle, etc.), it is determined that the user performs a selection operation and inputs information. Alternatively, when it is detected that the cursor has stayed for more than the preset time after moving to the virtual button, it is determined that the user has performed the selection operation.

It can be seen that in the above method of inputting information through a virtual keyboard, the user needs to select a virtual button by means of a cursor to input information. When the information is input through the virtual keyboard, the cursor is frequently moved to select the virtual button, which causes the user to operate cumbersomely and the input information is inefficient.

Detailed ways

The technical solutions of the present application will be clearly and completely described in the following with reference to the specific embodiments of the specification and the accompanying drawings. It is apparent that the described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the specification without departing from the inventive scope are the scope of the application.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

FIG. 2 is a process of information input provided by an embodiment of the present invention, which may specifically include the following steps:

S100: Determine the information that has been input.

In one or more embodiments of the present specification, the information input process is equally applicable to a scenario in which information is input through a virtual keyboard. That is, the user may first input a virtual button on the virtual keyboard by moving the cursor, and then select the virtual button by operation to input information corresponding to the virtual button. That is, the process of inputting information by the user through two steps.

Each virtual button on the virtual keyboard can correspond to different information. The virtual keyboard can be displayed through a VR terminal, an AR terminal, a smart terminal, a personal computer, a mobile phone, a tablet computer, and the like. And, the user can control the movement of the cursor by operating the above device or a third party device that establishes a communication connection with the above device. Of course, this specification does not limit the specific device input information and how to control the cursor movement. The manner in which the above device displays the virtual keyboard is not limited in this specification (eg, through on-screen display, through projection display, etc.).

For example, when the user uses the VR helmet, the virtual keyboard is displayed by the screen of the VR helmet, and the up and down rotation of the user's head can be sensed by the sensor of the VR helmet itself, thereby allowing the user to control the movement of the cursor by rotating the head. Alternatively, the user can control the movement of the cursor through a controller that establishes a communication connection with the VR helmet. Wherein, the controller can be a somatosensory controller, a handle, a mouse, and the like. Alternatively, when using a personal computer, the user displays a virtual keyboard through the screen of the personal computer, and controls the movement of the cursor by moving the mouse, and the like.

In order to facilitate the subsequent description, in the present specification, the virtual keyboard is displayed by the VR helmet, and the VR helmet determines the position of the cursor by monitoring the rotation of the user's head as an example for subsequent description, and the device for performing the information input process may be VR helmet.

In addition, when a user inputs information, there may be a certain relationship (eg, vocabulary relationship, semantic relationship, etc.) between successively input information. For example, if the character "chan" has been input during Chinese character input, the input probability of the subsequent input character "g" is much larger than the input probability of other information. Therefore, in the process of performing information input, the VR helmet may first determine information that has been input through the virtual keyboard to determine the operations of subsequent steps.

Specifically, in the embodiment of the present specification, the method for inputting information may be: when it is monitored that the user performs an operation for any virtual button, according to the selection rule of the virtual button, it is determined whether the user's operation satisfies the selection rule, and if so, input The information corresponding to the virtual button, if not entered otherwise. Of course, the selection rules can be set as needed, and are not limited in this specification.

For example, when the operation time of the user performing a long press operation on the virtual key exceeds the selection duration of the virtual key, the information corresponding to the virtual key is input. Alternatively, when the user performs a double-click operation on the virtual key, the information corresponding to the virtual key is input. Alternatively, it is assumed that the selection rule is to select the information corresponding to the virtual button when the duration of the operation performed by the user on the virtual button exceeds the selection duration of the virtual button. Then, when the VR helmet determines that the user controls the cursor to perform a hovering operation on any virtual button, the VR helmet can first determine whether the cursor position corresponds to a virtual button, and if so, when the cursor hovering time exceeds the selection time of the virtual button, Enter the information corresponding to the virtual button, if not input, as shown in Figure 3.

3 is a schematic diagram of the user input characters provided in the present specification, wherein the broken line indicates the trajectory of the user moving the cursor by rotating the head, and the solid line indicates the position where the cursor hovers. The visible light target is hovered on the virtual button "I", and when the cursor hover exceeds the selection duration of the virtual button, the VR helmet inputs the information "I" corresponding to the virtual button, wherein around the virtual button "I" The progress bar with an arrow indicates the duration of the hover. When the progress bar with an arrow bypasses the virtual button for one week, it indicates that the hover time exceeds the selected duration.

For convenience of description in the subsequent description, when the selection rule is such that the duration of the operation of the virtual button exceeds the selection duration of the virtual button, the information corresponding to the virtual button is input as an example for description.

Specifically, the information corresponding to each virtual button on the virtual keyboard may be a character, an instruction, or the like, and each virtual button has a preset boundary. Moreover, when the cursor is located within the boundary of a virtual button, the selection duration of the virtual button can be determined, so as to determine whether to input according to the duration of the user's control cursor hovering on the virtual button and the selection duration of the virtual button. The information corresponding to the virtual button.

In addition, for a cursor that can move freely, when using the somatosensory technology to control the movement of the cursor, it is more difficult to hover the cursor completely on a virtual button. Therefore, in order to facilitate the user to input information, how can the user Make sure the cursor starts to hover and set. For example, the cursor can be hovered when the cursor enters the boundary of a virtual button. Alternatively, when the cursor movement rate is less than the preset rate, the cursor is hovered and the like, which is not limited in this specification.

Further, in the present specification, it is not limited to determine whether there is a virtual button at the position of the cursor, and whether the hover duration of the cursor exceeds the order of the selection duration. For example, if the basic duration is set in advance, after determining that the cursor hovering time exceeds the basic duration, it is determined whether the cursor position corresponds to a virtual button, and if so, whether the cursor hover length exceeds the selection duration of the virtual button, and if not , then do not judge.

It should be noted that, in this specification, the selection rule of each virtual button on the virtual keyboard may be preset, and the selection rules of each virtual button may not be completely consistent. For example, when the selection rule is that the duration of the operation of the virtual button exceeds the selection duration of the virtual button, when the information corresponding to the virtual button is input, the selection duration of the delete button may be longer to prevent the user from deleting the input information by mistake. . Of course, the purpose of the input information is not limited. For example, a user enters an account and password through a VR helmet, or a user enters a web address in a browser through a VR helmet, and the like.

S102: Determine an input probability of each virtual button on the virtual keyboard according to the input information and a preset algorithm.

In the embodiment of the present specification, after determining the information that has been input, the VR helmet may further determine an input probability of each virtual button according to a preset algorithm, so that subsequent steps may adjust a selection rule of each virtual button, so that the user inputs information more. Convenient.

Specifically, the VR helmet can calculate an input probability of each virtual button on the virtual keyboard according to the input information and a preset algorithm. The preset algorithm may be obtained by using a machine learning method, or may be an existing prediction algorithm, which is not limited in this specification.

In addition, since different users have different input habits, different common words, and the like, when determining the input probability of each virtual button, the virtual information may be further determined according to the information input in the history of the user. The input probability of the button.

Specifically, in the present specification, before determining the input probability of each virtual button, the user's historical input information may also be acquired, and according to the user's historical input information and/or the input information, a predetermined algorithm is used to determine each The input probability of the virtual button. The historical input information of the user may include: words, words, letter combinations, and the like that the user has entered in history. Moreover, since the user's common words and idioms may also change over time, when the user's historical input information is acquired, the user's historical input information may be acquired within a set period of time (eg, within six months). The preset time period can be set as needed, and the specification is not limited.

S104: Adjust the selection rule of the virtual button according to the input probability of the virtual button for the at least one virtual button.

In the present specification, after determining the input probability of each virtual button, the VR helmet may also adjust the selection rule of the virtual button according to the input probability of the virtual button for the at least one virtual button. For example, at least one virtual button may be determined according to an input probability of each virtual button, and the selected duration of the determined virtual button may be reduced.

In the present specification, the VR helmet may determine a virtual button that reduces the selected duration from each virtual button according to a preset probability threshold or quantity. Specifically, the VR helmet can select the virtual button according to the preset number according to the input probability of each virtual button from high to low, and reduce the selection duration of each selected virtual button. Therefore, the information corresponding to the virtual key with a higher input probability is more easily input.

In addition, in some cases, the input probability of individual virtual buttons may be much higher than other virtual buttons, and the input probabilities of other virtual buttons are not much different, as shown in Table 1.

虚拟按键Virtual Key	输入概率Input probability
AA	90％90%

BB	1％1%
CC	0.5％0.5%
DD	0.7％0.7%
EE	0.8％0.8%

FF	2％2%
……......	……......

Table 1

Assume that the input probability of the virtual button "A" in Table 1 is 90%, and the input probabilities of the remaining 25 virtual buttons "B to Z" and the functional virtual button are all below 5%. If the virtual button is also selected in a preset number, the virtual button with a low input probability may also be selected, which may easily lead to the problem of inputting an error message. Therefore, in the present specification, the VR helmet may further select at least one virtual button whose input probability is higher than the probability threshold from each virtual button according to a preset probability threshold, and reduce the selection duration of the selected virtual button.

Of course, the above two methods may be used alone or in combination, and the description is not limited. Moreover, if the input probability of no virtual button is higher than the probability threshold, the virtual button with the highest input probability may be selected to adjust the selection duration, or the selection duration of the virtual button may not be adjusted.

Further, in the present specification, the VR helmet can reduce the selection duration corresponding to the selected virtual button according to the fixed step size. For example, if the fixed step size is 1 second and the selection duration is 2 seconds, for the virtual button for adjusting the selected duration, the cursor only needs to hover for 1 second on the virtual button to input the information corresponding to the virtual button.

Further, since the input probabilities of the virtual keys determined in step S102 may not be completely the same, when the selection duration of the selected virtual keys is adjusted, the reduced selection duration may be positively correlated with the input probability of the virtual keys.

Specifically, for each selected virtual button, the VR helmet can proportionally reduce the selection duration of the virtual button according to the input probability of the virtual button. For example, assuming that the input probability of the virtual button "A" is 90%, the selection duration corresponding to the virtual button "A" can be reduced by 90%. For example, the formula is used to determine the selection duration of the virtual button, where y is the selected selection duration, x is the selection duration before the reduction, and n is the input probability of the virtual button. Further, it is assumed that the selection duration corresponding to the virtual button "A" is 2 seconds, and the selection duration corresponding to the reduced virtual button "A" is 2s × (1 - 90%) = 0.2s. That is to say, at this time, the cursor only needs to hover 0.2s on the virtual button "A" to input "A".

Based on the information input process shown in FIG. 2, according to the input information, the input probability of each virtual button in the process of inputting information is predicted, and the selection rule of the virtual button with high input probability is adjusted, so that the virtual button after adjusting the selection rule is adjusted. The corresponding information is easier to input, which can effectively improve the user's input efficiency.

In addition, when a cursor is used to input on a virtual keyboard, it is necessary to make the cursor enter the boundary of the virtual button before the selection operation can be performed. Therefore, in the present specification, in order to reduce the difficulty of selecting a virtual button with a high input probability, the VR helmet may determine at least one virtual button according to the determined input probability of each virtual button, and increase or decrease the area of the determined virtual button. Specifically, the VR helmet can increase the area of the virtual button whose input probability is greater than the preset value on the virtual keyboard according to the input probability of each virtual button, and/or reduce the area of the virtual button on the virtual keyboard whose input probability is less than the preset value. . Among them, the preset value can be set as needed.

For example, suppose that after the user inputs "desi", the VR helmet determines that the probability of subsequent input "R" and "G" is higher, 40% and 50% respectively, and further assumes that the preset value is 20%, which is displayed in the VR helmet. The virtual keyboard can be changed from Figure 4a to Figure 4b. Among them, it can be seen that the area of the virtual button "R" and the virtual button "G" is increased. Of course, it is also possible to reduce the area of other virtual keys with an input probability of less than 20%.

In the present specification, the number of virtual keys to be increased and the amount of reduction is not limited, and may be set as needed, as long as the virtual keys with higher input probabilities are more easily selected.

Further, in the above embodiment, the VR helmet is taken as an execution main body as an example. Of course, the process of inputting information can also be performed by other devices.

For example, when using a smart TV, the user controls the movement of the cursor between the virtual keys displayed on the smart TV through the remote control button, and selects the input information. Alternatively, the user uses a personal computer to move between virtual buttons and a virtual button to input information. Alternatively, the user uses the joystick of the handle to control the cursor displayed by the game console to move between virtual keys, select the input information, and the like. This specification does not specifically limit which device is the device that implements the information input method.

It should be noted that the execution bodies of the steps of the method provided in the embodiments of the present specification may all be the same device, or the method may also be performed by different devices. For example, the execution body of step S100 and step S102 may be device 1, and the execution body of step S102 may be device 2; or the execution body of step S100 may be device 1, and the execution body of step S102 and step S104 may be device 2; and many more. The foregoing description of the specific embodiments of the specification has been described. Other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than the embodiments and still achieve the desired results. In addition, the processes depicted in the figures are not necessarily in a particular order or in a sequential order to achieve the desired results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.

Based on the data auditing method shown in FIG. 1, the embodiment of the present specification further provides an information input device, as shown in FIG. 5.

FIG. 5 is a schematic structural diagram of an information input apparatus according to an embodiment of the present disclosure, wherein different information corresponds to different virtual keys on a virtual keyboard, and the apparatus includes:

The determining module 200 determines the information that has been input, wherein, for each input information, the virtual button corresponding to the information corresponds to a selection rule, where the information is when the user operates the virtual button to meet the selection rule of the virtual button.

The prediction module 202 acquires historical input information of the user, and determines an input probability of each virtual button on the virtual keyboard according to the historical input information of the user, the input information, and the preset algorithm. .

The selection rule is that when the duration of the operation of the virtual button exceeds the selection duration of the virtual button, the information corresponding to the virtual button is input.

The adjusting module 204 determines at least one virtual button according to the determined input probability of each virtual button, and reduces the selected duration of the determined virtual button.

In the 1990s, improvements to a technology could clearly distinguish between hardware improvements (eg, improvements to circuit structures such as diodes, transistors, switches, etc.) or software improvements (for process flow improvements). However, as technology advances, many of today's method flow improvements can be seen as direct improvements in hardware circuit architecture. Designers almost always get the corresponding hardware circuit structure by programming the improved method flow into the hardware circuit. Therefore, it cannot be said that the improvement of a method flow cannot be implemented by hardware entity modules. For example, a Programmable Logic Device (PLD) (such as a Field Programmable Gate Array (FPGA)) is an integrated circuit whose logic function is determined by the user programming the device. Designers program themselves to "integrate" a digital system on a single PLD without having to ask the chip manufacturer to design and fabricate a dedicated integrated circuit chip. Moreover, today, instead of manually making integrated circuit chips, this programming is mostly implemented using "logic compiler" software, which is similar to the software compiler used in programming development, but before compiling The original code has to be written in a specific programming language. This is called the Hardware Description Language (HDL). HDL is not the only one, but there are many kinds, such as ABEL (Advanced Boolean Expression Language). AHDL (Altera Hardware Description Language), Confluence, CUPL (Cornell University Programming Language), HDCal, JHDL (Java Hardware Description Language), Lava, Lola, MyHDL, PALASM, RHDL (Ruby Hardware Description Language), etc., are currently the most commonly used VHDL (Very-High-Speed Integrated Circuit Hardware Description Language) and Verilog. It should also be apparent to those skilled in the art that the hardware flow for implementing the logic method flow can be easily obtained by simply programming the method flow into the integrated circuit with a few hardware description languages.

The controller can be implemented in any suitable manner, for example, the controller can take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (eg, software or firmware) executable by the (micro)processor. In the form of logic gates, switches, application specific integrated circuits (ASICs), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, The Microchip PIC18F26K20 and the Silicone Labs C8051F320, the memory controller can also be implemented as part of the memory's control logic. Those skilled in the art will also appreciate that in addition to implementing the controller in purely computer readable program code, the controller can be logically programmed by means of logic gates, switches, ASICs, programmable logic controllers, and embedding. The form of a microcontroller or the like to achieve the same function. Such a controller can therefore be considered a hardware component, and the means for implementing various functions included therein can also be considered as a structure within the hardware component. Or even a device for implementing various functions can be considered as a software module that can be both a method of implementation and a structure within a hardware component.
