Description
本發明係有關於數位電視技術領域,且特別有關於一種遙控器的文字輸入方法和系統。
隨著數位電視的發展和雙向業務的推廣普及,在電視上輸入文字這種交互手段越來越受到用戶的重視。由於電視遙控器的功能鍵以數位鍵為主,要想輸入字元文字須將各個數位鍵映射成字元文字的不同組成部分,傳統的遙控器在電視上輸入字元,要一直用遙控器的方向鍵來控制,可能選一個字元就需要按很多次按鍵,大大影響了用戶在電視業務上的體驗且互動。
有鑒於此,本發明實施例提供一種遙控器的文字輸入方法,可以方便用戶在電視上進行文字輸入。
本發明實施例更提供一種應用該遙控器的文字輸入系統,可以方便用戶在電視上進行文字輸入。
本發明實施例之遙控器的文字輸入方法包括步驟:接收一遙控器指令;對該遙控器指令進行解碼;在一字庫中根據解碼後的該遙控器指令執行文字搜索操作;根據該文字搜索操作,在一螢幕上顯示一文字輸入法虛擬介面以及對應文字;感測該遙控器的移動;計算該遙控器在虛擬鍵盤上對應焦點移
動的速度v1;判斷該焦點移動的速度v1是否大於預設速度v;該遙控器焦點自動移動到與被標示出且距離小於等於預設距離d的文字;輸入該遙控器焦點所在的文字。
較佳地,所述在該字庫中根據解碼後的該遙控器指令執行該文字搜索操作還包括:根據輸入的文字搜索與所述文字相關聯的文字並標示出所述關聯文字。

較佳地,該預設速度為v=((P2-P1)*C2*s/r)/t,該預設距離為d=C1*s/r,其中P1為該遙控器焦點在該螢幕上移動前的起點,P2為該遙控器焦點在該螢幕上移動後的終點,C1、C2為常係數,s為電視機螢幕的尺寸,r表示通過機頂盒所設置的解析度,t表示該遙控器焦點在該螢幕從點P1移動到點P2所用時間。
本發明實施例之遙控器的文字輸入系統包括一接收模組、一解碼模組、一字庫模組、一文字搜索模組、一介面模組、一感測模組、一計算模組、一判斷模組。該接收模組用於接收一遙控器輸入的指令。該解碼模組用於對接收到的該遙控器的指令進行解碼。該字庫模組用於存儲一文字字庫。該文字搜索模組用於在該字庫中根據解碼後的該遙控器指令執行文字搜索操作。該介面模組用於根據該文字搜索操作,在一螢幕上顯示一文字輸入法虛擬介面以及對應文字。該感測模組用於感測遙控器的移動軌跡。該計算模組用於計算一遙控器焦點在螢幕上移動的速度v1的大小。該判斷模組用於判斷該遙控器焦點在該螢幕上移動的速度v1是否大於預設速度v,若速度v1大於預設速度v,該遙控器焦點自動移動到與被標示出且距離小於等於預設距離d的文字。該輸入模組用於輸入該遙控器焦點所在的文字。

處理器執行,以完成本發明。在本實施例中,該些模組由一處理器30執行。本發明所稱的該些模組是完成一特定功能的電腦程式段。一記憶體20用於存儲遙控器的文字輸入系統10的程式碼等資料。

該字庫模組300用於存儲一文字字庫,該字庫分門別類地劃分,比如英文字庫、拼音字庫、五筆字庫等。
該文字搜索模組400用於根據該解碼指令搜索對應文字。根據輸入的該文字搜索與該文字相關聯的文字並標示出該關聯文字。參閱圖2,例如,當使用者輸入文字“D”時,其文字搜索模組會自動搜索並標示出關聯文字“E”、“Y”、“I”、“O”等,且會在文字輸入法的上方出現相應的候選字“Defeat”、“Do”、“Does”等。
該介面模組500用於顯示一文字輸入法虛擬介面以及對應文字,該介面模組還用於當一遙控器焦點在一螢幕上小範圍內準確移動困難時可以根據該遙控器指令啟動放大功能,放大所要選取文字所在的小範圍該輸入法虛擬介面,方便該遙控器焦點在放大的小範圍輸入法虛擬介面上移動、選取文字,參閱圖3。

步驟S10,接收該遙控器輸入的指令,其中指令包括啟動/切換/關閉輸入法、確定輸入、刪除等。
步驟S11,對接收到的該遙控器的指令進行解碼。例如,如果接收到的該遙控器的指令解碼為啟動一文字輸入法,則調用該文字輸入法;如果接收到的該遙控器的指令解碼為切換該文字輸入法,則切換該文字輸入法;如果接收到的該遙控器的指令解碼為輸入文字,則將該解碼指令發送給該文字搜索模組。
步驟S12,根據該解碼指令在該文字庫中搜索對應文字。根據輸入的文字搜索與該文字相關聯的文字並標示出該關聯文字。參閱圖2,例如,當使用者輸入文字“D”時,其該文字搜索模組會自動搜索並標示出關聯文字“E”、“Y”、“I”、“O”等,且會在文字輸入法的上方出現相應的候選字“Defeat”、“Do”、“Does”等。該文字字庫分門別類地劃分,比如英文字庫、拼音字庫、五筆字庫等。
步驟S13,顯示該文字輸入法虛擬介面以及對應文字,當該遙控器焦點在該螢幕上小範圍內準確移動困難時可以根據該遙控器指令啟動放大功能,
