[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0046] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0047] An embodiment of the present application provides a keyboard, which includes an operation panel, a control circuit and a base plate.

[0048] Among them, the operation panel is the user's operable area, connected to the control circuit, and the operation panel is provided with multiple button groups, at least some of the buttons in the multiple button groups can be reused, and the user can input content by triggering different button groups.

[0049] A control circuit is used to identify a trigger operation on an operation panel, generate a corresponding control signal according to the trigger operation, and send the control signal to a host, so that the host establishes a mapping relationship between a specified syllable in a preset syllable and the output of a corresponding specified key position in the host according to the control signal, and establishes a mapping relationship between other syllables and the output of the key positions corresponding to other syllables in the host according to the usage frequency of the mutually exclusive syllables and other syllables, and performs text input in response to the trigger operation according to the mapping relationship; mutually exclusive syllables represent syllables with mutually exclusive relationships among other syllables except the specified syllables.

[0050] The bottom plate is arranged below the operation panel and is used for supporting the operation panel. The bottom plate is provided with a control circuit.

[0051] like Figure 1 As shown, the keyboard-based text input method provided in the embodiment of the present application includes:

[0052] S101: Divide the plurality of keys included in the operation panel into a plurality of key groups according to input types of the plurality of keys, and determine a target key group for text input from the plurality of key groups.

[0053] The operation panel is provided with a plurality of keys, and the plurality of keys can be divided into a plurality of key groups according to the input types of the plurality of keys. For example, the input type can be determined according to the type of the typed content, including text input, punctuation input, number input, command input, etc. After dividing the plurality of key groups, it is necessary to determine the target key group for text input from the plurality of key groups of different types mentioned above. It is understandable that in the embodiment of the present application, the target key group corresponds to 26 letters, which are used to realize the input of Chinese characters.

[0054] S102: Determine the syllable type corresponding to the preset syllable, and establish a mapping relationship between the designated syllable in the syllable and the output of the corresponding designated key position in the host according to the syllable type; the designated key position is located on the target key group.

[0055] The preset syllables are commonly used Chinese phonetic symbols. First, according to the preset language decomposition rules, the preset syllables need to be decomposed into 23 initials and 35 finals, and then the number of first syllable units contained in the finals and the phonation position are determined, so that the finals are divided into simple finals, complex finals, and trisyllabic finals according to the number of first syllable units, and the finals are divided into front nasal finals and back nasal finals according to the phonation position. Among them, the simple finals include a, o, e, i, u, ü, the complex finals include ai, ei, ui, ao, ou, iu, ie, üe, er, the trisyllabic finals include ia, iao, ian, iang, iong, ua, uo, uai, uan / üan, uang, üan, the front nasal finals include an, en, in, un, ün, and the back nasal finals include ang, eng, ing, ong.

[0056] For different syllable types, a mapping relationship needs to be established between the syllables of the type and the output of the keyboard key positions in the host. This mapping relationship enables the host to output the text content corresponding to the key positions after the user triggers the key positions of different syllables.

[0057] In one embodiment, when the syllable type is an initial consonant, the number of second syllable units corresponding to the designated syllables is determined. For the first designated syllable whose second syllable unit number is a monosyllable, a mapping relationship is established between the first designated syllable and its corresponding first designated key position output in the host. The first designated key position refers to the actual position of the first designated syllable on the keyboard. For example, for monosyllabic initial consonants such as b, p, and m, the corresponding first designated key position is determined as B, P, and M according to the letter position on the American keyboard. After the mapping relationship corresponding to the first designated syllable is established, it is determined whether the unassigned key positions in the target key group other than the first designated key position correspond to independent syllables, so as to select the second designated key position from the unassigned key positions. The unassigned key positions refer to the remaining key positions that are not used as initial consonants, namely E, U, I, O, A, and V. Among them, E, A, and O in the unassigned key positions are independent syllables and are usually not reused. Therefore, the second designated key positions are U, I, and V. For the second designated syllable whose second syllable unit quantity is a disyllabic second designated syllable, a mapping relationship is established between the second designated syllable and its corresponding second designated key position output in the host. For example, for disyllabic initials such as zh, ch, and sh, the corresponding first designated key positions are determined as V, I, and U according to the letter positions on the American keyboard.

[0058] S103: Determine mutually exclusive syllables among the syllables, where the mutually exclusive syllables refer to syllables in other syllables except the designated syllables that have a mutually exclusive relationship.

[0059] After the above steps, the mapping relationship between the initial consonant and the corresponding designated key position output in the host has been established. In order to improve the efficiency of text input, the syllables other than the designated syllables in the preset syllables can be reused, that is, a certain key position actually corresponds to multiple syllables, so that when inputting text, there is no need to input a single syllable in sequence, and the input efficiency is higher. It should be noted that the reused syllables corresponding to the reused key positions should be mutually exclusive and have similar pronunciation or structure. The mutually exclusive relationship means that any multiple syllables will not appear at the same time when inputting text. For example, iong / ong, uang / iang, ia / ua, o / uo, ü / ui, un / ün, and uan / üan are mutually exclusive syllables.

[0060] Determine whether there are mutually exclusive syllables in other syllables, which can be achieved by the following steps:

[0061] Feature extraction is performed on multiple syllables contained in other syllables to obtain reading features corresponding to multiple syllables. The reading features are input into the classifier for classification processing, so as to filter out similar syllables belonging to the same reading category from other syllables. However, multiple syllables in similar syllables are not mutually exclusive. It is necessary to further determine whether the syllables in the above similar syllables have a mutually exclusive relationship. If so, they are mutually exclusive syllables.

[0062] S104: Obtain the usage frequencies of other syllables, and establish a mapping relationship between the output of other syllables and the key positions corresponding to the other syllables in the host according to the usage frequencies of the mutually exclusive syllables and the other syllables, so as to obtain the target key group after layout.

[0063] Before establishing mapping relationships corresponding to other syllables, the operation panel needs to be partitioned according to the preset operation habits to obtain the first operation area and the second operation area. The first operation area and the second operation area are the operation areas of the user's left and right hands respectively. After the operation areas are divided, the positioning keys of the first operation area and the second operation area are determined respectively. Usually, the positioning key of the first operation area is F, and the positioning key of the second operation area is J.

[0064] In one embodiment, the designated key position corresponding to the designated syllable is determined, and other syllables need to establish a mapping relationship with the output of at least some of the designated key positions in the host, so as to achieve key position reuse. Then, according to the usage frequency of other syllables, the mapping relationship between other syllables and the output of the designated key positions in the host is established in sequence, so that the difference between the sum of the usage frequencies of other syllables respectively included in the first operation area and the second operation area is less than a preset threshold. When establishing the mapping relationship, it is ensured that the sum of the usage frequencies of other syllables included in the first operation area and the second operation area is basically the same, so that the frequency of the left and right hands can be kept consistent as much as possible when inputting text, thereby improving input efficiency.

[0065] When establishing mapping relationships for other syllables, if there are mutually exclusive syllables among other syllables, mapping relationships will be established between the other syllables and the mutually exclusive syllables of other syllables and the output of the same designated key position in the host, thereby ensuring that, on the basis of a designated key position corresponding to a designated syllable, the above-mentioned mutually exclusive syllables can be reused at the same time, thereby eliminating the need to enter individual syllables in sequence according to the phonetic sequence of Chinese characters, greatly improving input efficiency and saving key layout area.

[0066] In one embodiment, it is also necessary to establish a mapping relationship between other syllables and their corresponding key positions in the host according to the usage frequency of other syllables and whether there are mutually exclusive syllables. Table 1 shows the usage frequency of other syllables:

[0067] Table 1

[0068]

[0069]

[0070] As shown in Table 1, among other syllables, an is the most frequently used syllable. When establishing a mapping relationship, it is necessary to establish a mapping relationship between the most frequently used syllable and the output of the positioning key in the host to ensure that the operation position of the syllable is the most convenient.

[0071] For the syllable er with the lowest frequency of use, due to its independent existence, it is not used in combination with any initial consonant, and basically has a mutually exclusive relationship with all finals. Therefore, when establishing its corresponding mapping relationship, first determine the other key positions in the target key group except the specified key position, namely E, A, and O. The syllable with the lowest frequency of use among other syllables is used as the target syllable, namely er, and the combined syllable used in combination with the target syllable is determined from the syllables corresponding to other key positions. It should be noted that the combined syllable does not mean that the target syllable and the combined syllable can be pronounced in combination, but means that when the key position is reused, the corresponding key positions of the above two syllables need to be triggered to complete the entry of the target syllable. After determining the combined syllable, the target syllable and the combined syllable are respectively mapped with the corresponding specified key position and the output of the target other key positions in the host, and the specified key position is located in the first operating area, and the target other key positions are located in the second operating area. For example, when the combined syllable is O, in order to take into account the usage frequency of the left and right hands, a mapping relationship should be established between the target syllable er and the output of the designated key position in the first operating area in the host.

[0072] S105: In response to a trigger operation on the laid-out target button group, text input is performed.

[0073] Figure 2 A schematic diagram of the layout of a target button group provided in an embodiment of the present application. Figure 2 As shown, each initial consonant can establish a mapping relationship with the output of its corresponding designated key position in the host, and except for independent syllables A and E that can be pronounced independently, other key positions are reused. The host can input text in response to the trigger operation of the target key group after layout. Through the above-mentioned multiplexed key positions, not only can multiple syllables be input when the target key group is triggered once, but also the frequency of use of the left and right hands can be taken into account when inputting text, which effectively improves the user experience.
