Description

觸控螢幕縮放命令方法
本發明係關於一種觸控螢幕縮放圖像的命令方法。
目前,具有觸控螢幕的手機已被市場廣泛接受,其通常為尺寸較小的電阻式觸控螢幕,只接受單點觸控。關於圖像移動,目前都是在螢幕上畫直線,分別向上、下、左、右畫直線,表示移動圖像或向前向後翻頁。其圖像縮放命令常用雙點連續點擊來表示放大或縮小命令。此種觸控縮放命令方法不能連續放大或縮小,且與電腦的操作不一致,容易造成混淆。對於大尺寸的觸控面板,通常為電容式觸控螢幕,其能接受兩點觸控,可以用兩觸點分開移動表示放大命令,兩觸點靠攏移動表示縮小命令。此種觸控縮放方法直觀,但多點觸控螢幕價格稍貴,且必須控制兩個點,操作不是很方便。
本發明之自的係提供一種觸控螢幕縮放圖像的命令方法,其操作方便且直觀。
為解決上述技術問題,本發明提供一種觸控螢幕縮放命令方法,其利用單點不離開螢幕接觸產生連續軌跡的信息表示螢幕圖像的縮放命令。
本發明提供之觸控螢幕縮放圖像的命令方法,其操作方便且簡單 直觀,便於較遠距離操作,利於降低設備成本。
第一圖係在螢幕上畫漸開線的圖示;第二圖係在螢幕上反向畫漸開線的圖示。
本發明提供一種觸控螢幕縮放命令方法,其利用單點不離開螢幕接觸產生連續軌跡的信息表示螢幕圖像的縮放命令。
其具體實施方案包括如下步驟:提供一觸控螢幕;提供連接前述觸控螢幕的處理單元,其能接收並存儲觸控螢幕上一個觸點的接觸軌跡P1、P2、P3、P4。。。PN,各點的位置為(X1,Y1)、(X2,Y2)、(X3,Y3)、(X4,Y4)。。。(XN,YN);提供安裝於處理單元的應用軟體,其能以時間順序,選取接觸軌跡上的第一組接觸點P1、P2、P3,第二組接觸點P2、P3、P4與第三組接觸點P3、P4、P5,命各組接觸點所在圓周的圓心位置為(Xs,YS),圓半徑為R,以圓周上的各點到圓心的距離相等為條件,得出一下方程組:R=[(X1-XS)2+(Y1-YS)2]1/2=[(X2-XS)2+(Y2-YS)2]1/2=[(X3-XS)2+(Y3-YS)2]1/2
根據上述方程組計算可以得出各組點所在圓周的半徑R,命第一組點所在圓周半徑為第一曲率半徑R1,第二組點所在圓周半徑為 第二曲率半徑R2,第三組點所在圓周半徑為第三曲率半徑R3,然後比較各曲率半徑,如果第二曲率半徑R2大於第一曲率半徑R1,則執行將螢幕圖像放大的命令,如果第二曲率半徑R2小於第一曲率半徑R1,則執行將螢幕圖像縮小的命令;第三曲率半徑R3及之後的點曲率半徑表示的命令以此類推。
在上述觸控螢幕縮放命令方法,其中每次放大或縮小的倍數為第二曲率半徑R2與第一曲率半徑R1的比值,也可以使每次放大或縮小固定倍數。
另外,為了防止誤操作,在一條接觸軌跡中,出現單個放大或縮小命令時,此單個命令可以不予執行。即,若第一曲率半徑R1>第二曲率半徑R2>第三曲率半徑R3,則執行圖像縮小的命令;若第一曲率半徑R1>第二曲率半徑R2<第三曲率半徑R3=>不動作;若第一曲率半徑R1<第二曲率半徑R2>第三曲率半徑R3=>不動作;若第一曲率半徑R1<第二曲率半徑R2<第三曲率半徑R3,則執行圖像放大的命令。並且,為了防止誤操作,接觸軌跡兩端一定長度的曲率數據不作為表示螢幕圖像的縮放命令。其中在曲率半徑大於特定長度時,執行移動螢幕圖像的命令,所述觸控螢幕設置有檢測設定系統,操作者可以設定方便其操作的前述特定長度曲率半徑。
以上每組接觸點為三個,且取點有重合,作為其他實施方式,還可以每組取更多個接觸點,根據多個接觸點取得多個曲率半徑,根據較接近的曲率半徑,而不用尺寸特大或特小的曲率半徑。還可以取不重合的點,如第一組接觸點為P1、P2、P3,第二組接觸點為R8、R9、P10。接觸軌跡上,所有接觸點按接觸時間間隔選取 ,例如時間間隔為0.1秒。根據操作者習慣不同,還可以接觸點在接觸軌跡固定長度間隔選取,例如固定長度間隔為1毫米。
對於上述觸控螢幕縮放命令方法,其中最直觀的操作方式就是在螢幕上畫漸開線(請參閱第一圖,食指觸控螢幕),則執行觸控螢幕圖像放大的命令,在螢幕上反向畫漸開線(請參閱第二圖,食指觸控螢幕),則執行觸控螢幕圖像縮小的命令。
作為本發明其他實施方式,可以在螢幕上畫順時針的弧線,則執行觸控螢幕圖像放大的命令,在螢幕上畫逆時針的弧線則執行觸控螢幕圖像縮小的命令。或者,在螢幕上畫順時針的弧線則執行觸控螢幕圖像縮小的命令,在螢幕上畫逆時針的弧線則執行觸控螢幕圖像放大的命令。此種方式操作更為方便,且不易出錯。
另外,作為本法明的其他實施方式,還可以是在觸控螢幕上連續地(不離開螢幕)畫其他圖形表示螢幕圖像放大的命令。如先畫一條短橫,保持觸點接觸,停頓一下之後,再畫一條長橫,表示放大命令;先畫一條長橫,保持觸點接觸,停頓一下之後,再畫一條短橫,表示縮小命令。再如畫『a』表示放大,畫『s』表示縮小。再如連續畫橫豎表示放大,連續畫豎橫表示縮小。
綜上前述,本創作確已符合發明專利之要件,爰依法提出專利申請。惟,以上所述者僅係本發明之較佳實施方式,本發明之範圍並不以上述實施方式為限,舉凡熟習本案技藝之人士援依本發明之精神所作之等效修飾或變化,皆應涵蓋於以下申請專利範圍內。
