Description

使用觸控裝置控制螢幕上游標的定位方法
本發明係有關一種觸控裝置，特別是關於一種使用觸控裝置控制螢幕上游標的定位方法。
現今的觸控技術發達，除了傳統行動裝置的小尺寸觸控螢幕外，已經發展出支援多點觸控螢幕的作業環境，例如微軟公司的Windows 7或iPhone OS等作業系統，可將作業環境延伸至桌上型裝置，使用大尺寸觸控螢幕，讓使用者依直覺操作。但大尺寸觸控螢幕有成本高、限制使用者於螢幕前操作等缺點，而觸控螢幕以外的觸控裝置，由於手指並非直接在螢幕上操作，無法依直覺控制螢幕上的游標。又因為觸控裝置及螢幕的解析度通常不一樣，所以物件在觸控裝置上的座標無法直接對應到螢幕上。
本發明的目的，在於提出一種使用觸控裝置控制螢幕上游標的定位方法。
根據本發明，一種使用觸控裝置控制螢幕上游標的定位方法係根據物件在該觸控裝置上移動的相對座標，改變代表該物件的游標在該螢幕上的顯示座標，當該物件離開該觸控裝置超過預設時間後，於該螢幕上隱藏該游標，當該游標無顯示在該螢幕上且有物件觸碰該觸控裝置時，根據該物件在 該觸控裝置上的絕對座標與該觸控裝置對該螢幕的解析度比例，計算該游標在該螢幕上的起始顯示座標。
用來執行本發明的控制方法的觸控裝置，可為筆記型電腦上的觸控裝置，或是外接的電腦週邊裝置。若為後者，且利用無線傳輸與受控裝置溝通，則使用者的操作不用侷限在螢幕前。使用者在觸控裝置上操作時，螢幕上會顯示代表使用者在該觸控裝置上的手指或其他物件的游標，該觸控裝置會依受控裝置所支援的資料格式傳送與遊標相關的資訊給受控裝置。由於有多物件在觸控裝置上操作時可能會有游標位置交錯或游標不直覺對應等問題發生，因此本發明的控制方法會於物件離開觸控裝置時，計算離開之時間，若超過預設時間，便自動隱藏代表該物件的游標；則游標會於物件再次接觸到觸控裝置時，根據該物件在該觸控裝置上的絕對座標與該觸控裝置對該螢幕解析度的比例，計算該游標在該螢幕上的起始顯示座標。
圖1係根據本發明之實施例的流程圖。步驟S12判斷是否有物件在觸控裝置上，若為否，則到步驟S14判斷代表物件的游標是否顯示在螢幕上，若為是，則到步驟S16檢查該物件離開觸控裝置的時間是否超過預設時間，若為是，則到步驟S18自動隱藏代表該物件的游標。若步驟S12判定有物件在觸控裝置上，則到步驟S20判斷游標是否顯示在螢幕上，若為是，則到步驟S22根據物件在觸控裝置上移動的相對座標改變游標的顯示座標。若步驟S20判定無游標顯示在 螢幕上，則到步驟S24以是否存在游標的其他資訊判斷是否為第一次觸碰觸控裝置，若為是，則到步驟S26根據觸控裝置對螢幕之解析度比例計算游標在螢幕上的啟始顯示座標，否則到步驟S22改變游標的顯示座標。在某些實施例中，步驟S18更包含刪除該游標的所有資訊，包括顯示座標，如此可在步驟S20判定無游標顯示在螢幕上後，直接進行步驟S26定位出游標在螢幕上的啟始顯示座標，省去步驟S24的判斷。
圖2係根據觸控裝置對螢幕之解析度比例計算游標在螢幕上的啟始顯示座標的示意圖。當物件30第一次觸碰觸控裝置32，圖1的步驟S26便根據觸控裝置32對螢幕34之解析度比例計算游標36在螢幕34上的啟始顯示座標
圖3係多物件操作下根據觸控裝置對螢幕之解析度比例計算游標在螢幕上的啟始顯示座標的示意圖。當使用者利用多物件操控觸控裝置32時，除了物件30如圖2所述，代表另一物件38的游標40，亦係根據觸控裝置32對螢幕34之解析度比例計算其在螢幕34上的啟始顯示座標
上述座標計算完成後，若使用者在觸控裝置32上滑動物件30或38，則螢幕34上的游標36或40將根據物件30或38在觸控裝置32上移動的相對座標，改變其在螢幕34上的顯示座標。當物件30或38離開觸控裝置32未超過預設時間，其游標36或40的最後座標將保留，故使用者可多 次透過相對座標的移動操作，讓螢幕34上的游標36或40做長距離的顯示座標移動或其他操作。
以上對於本發明之較佳實施例所作的敘述係為闡明之目的，而無意限定本發明精確地為所揭露的形式，基於以上的教導或從本發明的實施例學習而作修改或變化是可能的，實施例係為解說本發明的原理以及讓熟習該項技術者以各種實施例利用本發明在實際應用上而選擇及敘述，本發明的技術思想企圖由以下的申請專利範圍及其均等來決定。
