Fig. 1 is a flowchart of an alphabet input method of a virtual keyboard of a set-top box according to a first embodiment of the present invention. As shown in fig. 1, in a first embodiment of the method for inputting letters by a virtual keyboard of a set-top box according to the present invention, the set-top box receives user input through a remote controller, and displays the virtual keyboard through a television or a display screen; the remote controller comprises up, down, left and right direction keys and a confirmation key; the set-top box stores an association database, wherein the association database comprises association frequency (namely association times) among letters, association frequency among pinyin of Chinese characters or association frequency among English words, and the method comprises the following steps:
s110, displaying a virtual keyboard, wherein the virtual keyboard comprises a first key area and a second key area; the first key area comprises a preset number of letter keys distributed according to a preset sequence;
FIG. 2a is a layout display diagram of the virtual keyboard shown in FIG. 1 according to the first embodiment of the present invention. Taking the input of the pinyin as an example, in step S110, the first key area 21 of the virtual keyboard includes 23 initial keys for displaying the initial to be input; in the first embodiment of the present invention, in order to reduce the number of key presses as much as possible, the second key press area 22 is arranged in the central area of the virtual keyboard, and the initial keys in the first key press area 21 are arranged around the second key press area 22; in particular, in the implementation, the first key area 21 may also be disposed on at least one of the left side, the right side, the upper side, and the lower side of the second key area 22. The second key area 22 comprises 9 virtual keys arranged in 3 rows and 3 columns, and the second key area 22 is used for displaying the selected initial consonant and the final associated with the selected initial consonant; specifically, in the application, the number of keys in the second key area 22 and the matrix distribution mode may be set according to the number of vowels. The 23 initial keys in the first key area 21 shown in fig. 2a are arranged in the order of the initial keys b-w, so that the user can quickly find the initial keys; or, to further reduce the number of times that the user moves the cursor, 23 consonants may be sequentially distributed on the keys located from near to far away from the center key 221 of the second key zone according to the usage frequency, for example, the consonant with higher usage frequency is distributed on the key located close to the second key zone, and the consonant key with lower usage frequency is distributed on the key located far away from the second key zone. Initially, the display on the virtual key in the second key region 22 is empty, and the cursor is located on the center key 221.
S120, detecting the selected letters input by the user in the first key area, and displaying the selected letters on a key of the second key area except the central key;
taking the input of the pinyin of the chinese character "light" as an example, in step S120, the user moves a cursor to the initial letter key "g" in the first key zone 21 and selects to input "g", the set-top box detects the user input "g", and displays the selected initial letter "g" on a key other than the center key 221 in the second key zone 22. As shown in fig. 2b, which is a virtual keyboard display diagram of the first embodiment of the present invention, the steps S120 and S130 are performed, and the selected initial letter "g" is displayed on the key on the left side of the center key 221.
S130, searching a continuing letter or a continuing letter sequence associated with the selected letter, and sequentially displaying the continuing letter or the continuing letter sequence on a central key of the second key area and the rest keys in the second key area, which are far away from the central key, according to the sequence of the association frequency from high to low; and placing the cursor on the central key;
in step S130, a subsequent vowel associated with the selected initial "g" in the association database of the set top box is searched, and as shown in fig. 2b, the vowel associated with "g" including "a", "e", "o", and "u" is searched. Wherein the frequency of association of "a" with "g" is the highest, and "a" is displayed on the center key 221; the association frequencies of "e", "o", "u" and "g" are sequentially decreased, and the remaining vowels "e", "o" and "u" continuing to "g" are displayed on the remaining keys except for the keys "g" and "a" in the second key region 22.
S140, adding the continuous letters or continuous letter combinations input by the user to the tail of the selected letters to generate a selected letter sequence, and displaying the selected letter sequence on the keys displaying the selected letters.
Fig. 2c is a diagram of the virtual keyboard display executed in step S140 in the first embodiment of the present invention shown in fig. 1. As shown in fig. 2c, in step S140, it is detected that the user moves the cursor to the key displaying the final "u", and selects the input "u", adds "u" to the end of "g" to generate the sequence "gu", and updates the display "gu" on the key displaying "g".
Fig. 3 is a flowchart of an alphabet input method of a virtual keyboard of a set-top box according to a second embodiment of the present invention. In the second embodiment of the present invention shown in fig. 3, steps S110 to S140 in the first embodiment of the present invention are included, and step S140 further includes: and updating and counting the association frequency of the selected letters and the continuing letters or the continuing letter sequences. After step S140, the method further comprises the steps of:
s150, judging whether the selected letter sequence is confirmed as target input by the user, if not, repeating the step S130 and the step S140 until the target input is completed.
In step S140, it is detected that the user selects "u" as the succeeding vowel of the initial "g", the number of times of association between "g" and "u" is increased by 1 accordingly, and the association database is updated.
After step S140, the user does not complete the input of the "light" pinyin "guang", and the set-top box does not detect that the user sends a signal for confirming that the target input is completed through the remote controller, and returns to step S130 to continue to search the association database for the following vowel associated with "gu". As shown in fig. 2c, the final succeeding "gu" is only "a", and "a" is displayed on the center key 221 of the second key region 22, and the cursor is placed on the center key 221. The user directly selects the "a" input without moving a cursor. Fig. 4a is a diagram of a virtual keyboard display in which steps S130 and S140 are repeatedly performed in the second embodiment of the present invention shown in fig. 3. As shown in fig. 4a, the set-top box receives a succeeding vowel "a" input by the user, adds "a" to the end of the selected letter sequence "gu" to generate a new selected letter sequence "gua", updates the display "gua" on the button displaying "gu", adds 1 to the number of times of association between "gu" and "a", and updates the association database. Continuously detecting whether the user sends a signal for confirming that the target input is finished through the remote controller, judging that the target input is not finished, continuously returning to the step S130, and finding out n and ng of the continuous vowels associated with the gua in the association database; where "n" is associated with "gua" more frequently, the center key 221 in the second key region 22 is displayed with "n" and "ng" is associated with "gua" less frequently, and "ng" is displayed on one of the remaining keys of the adjacent center key 221. The user is detected to move the cursor to the key displaying "ng" and confirm the input, the "ng" is added to the end of "gua" to generate the selected letter sequence "guang", the number of times of association between "gua" and "ng" is added by 1, and the association database is updated, thereby completing the target input. By adopting the letter input method of the set-top box virtual keyboard, the light Chinese pinyin input is completed by 4 times of cursor selection g, 1 time of cursor selection u, direct selection a, 1 time of cursor selection ng and clicking of 6 times of direction keys and 5 times of confirmation keys for 11 times; with the "QWERTY" keyboard, at least 3 times of cursor movement to select "u" (assuming that the cursor is initially on the key "g"), 7 times of cursor movement to select "a", 6 times of cursor movement to select "n", and 2 times of cursor movement to select "g", and 23 times of key pressing with 18 directional keys and 5 confirmation keys are required. Therefore, the second key area 22 is arranged in the central area of the virtual keyboard, and the letter keys in the first key area 21 are arranged around the second key area 22 according to the input habit of the user in the preset order, so that compared with the traditional keyboard layout mode, the times of moving a cursor by the user are reduced, and the user experience can be improved; the association frequency of the input selected letters and the successive letters is counted, the successive letters or the successive letters are sequentially displayed on the central key 221 of the second key area and the keys which are far away from the central key 221 according to the order from high to low of the association frequency of the selected letters, and the cursor is placed on the central key again after the letters are input each time, so that the input accuracy is improved while the quick input is realized.
Preferably, after the input of the "light" Chinese character is completed, the pinyin of the following Chinese character associated with the "light" in the association database is searched, and the pinyin of the following Chinese character is displayed on the central key 221 and the keys which are distant from the central key 221 in sequence according to the height of the association frequency. FIG. 4b is a diagram of a virtual keyboard display associated with the Pinyin of the Chinese characters shown in FIG. 3 according to a second embodiment of the present invention. As shown in fig. 4b, the pinyin "ming" for the chinese character "ming" with the highest frequency of association with "light" is displayed on the center key 221, and then the pinyins for the other chinese characters associated with "light" are displayed on the remaining 8 keys of the second key region 22.
