Description of the Invention: [Technical Field] The present invention relates to a palm-type electronic device for controlling a cursor in a screen by using a touchpad (t〇uchpad), in particular, a positioning method using a touchpad is matched with a palm type The cursor system can accurately operate on a graphical interface without the touch screen. [Prior Art] In today's ever-changing technology, most handheld electronic devices or personal digital assistants (PDAs) use a touch screen (t〇uchpanel) to operate the graphical interface, but considering the cost of production. There are still many electronic devices on the market that do not have a touch screen. Usually, these products can only use buttons, scroll wheels or turntables to operate the interface. When the function is complicated, there may be more simple items in the menu, which may cause inconvenience in the operation of the materials. Therefore, the traditional operation mode is not applicable to the electronic device of the graphical interface. Therefore, there is a need for a cursor electronic device that is convenient for the user to control the cursor of the screen, and to provide a more (4) environment for grasping the positioning accuracy, the moving speed of the cursor, and the sensitivity of the sensor. SUMMARY OF THE INVENTION In view of the above background of the invention, the inconvenience of using a button, a scroll wheel or a view to operate a graphical interface is conventional. The main object of the present invention is to provide a f-type electronic device with a touchpad (four) screen cursor.

According to the above object, the present invention provides a touch panel method with a + _ vernier line, which can be called a graphical interface to operate on an electronic device. The ^= standard electronic device, which contains a cursor display interface, allows the user to change the color, style, size and change of the __ material and (4) range, and allows the cursor to be accurately moved to each place on the screen for positioning. And click. [Embodiment] Next, the present invention is detailed (4). The first embodiment of the present invention is a handheld game device. There is a screen and a screen 104. The screen 1〇4 itself is a graphical interface, and there is a cursor 106. The user moves the cursor 1〇6 by using the touchpad 1〇2, thereby operating the palm type. Device. The second figure is a block diagram of a system in accordance with an embodiment of the present invention. The computer system of the present invention includes a touchpad 102, a host computer 204, and a display device 206. The touchpad 102 itself has a contact-inductive surface as an input device for the host computer 204, which can be fabricated using conventional contact-sensing techniques, such as capacitive sensing or resistive sensing, which are typically manipulated by the user's fingers. . The continuous information packet with the coordinate data is transmitted by the touch panel 102, and the 200830163 mobile track of the cursor is calculated with the host computer 204 and the set moving speed, and the corresponding cursor is displayed on the display device 206 and can be directed to the cursor. Click on the item you want to point to. The second figure is a touch panel architecture 3 according to an embodiment of the present invention. Inside the touch panel 102, there is mainly a sensor 3〇2 and a converter. The touchpad 102 is a kind of pointing device, which is generally used to replace the traditional mouse. It is commonly used in laptop computers. It is characterized by sensitive sensing and fast moving of the cursor. The design concept is to use finger sliding. To move the upstream display of the screen is an increasingly common input device. Due to its small size and light weight, it is ideal for portable computer devices or PDAs. The principle of the touch panel 102 can be capacitive sensing or resistive sensing. The former is when the user's finger touches the touch panel 1 〇 2, and the capacitance is changed. The sensor 302 inside the touch panel 1 〇 2 The amount of change in capacitance is detected, converted into electronic data by the converter 3〇4, and converted into coordinates (horizontal axis, vertical axis, and offset angle) to be transmitted to the computer, thereby controlling the moving direction of the cursor, in other words, The touchpad 102 senses the movement of the finger by capacitive sensing; the latter is not described here. The touchpad 102 is not sensitive to the heat of the finger, but the finger changes the electrostatic field on the panel when it touches the panel surface, while other objects such as pencils or ballpoint pens cannot have the same effect, so the touchpad 102 Different from the tablet. Figure 4A is a flow diagram 400 of a palm cursor system operation in accordance with an embodiment of the present invention. First, step 4〇2 detects whether the sensor is touched, that is, whether the user's finger touches the touchpad and has a moving condition. If no, 200830163=the sensor continues to sense; if yes, the sensor performs the step. The side generates new contact location data and proceeds to the next step. Step 4〇4 The absolute coordinates transmitted by the device are calculated by the host computer. The relative position of the cursor is calculated. At this time, the old contact position data and the cursor speed data are required to be used to fine-tune the cursor information. Touching the coffee:: The relationship between the speed and the speed of the swim 4 is, for example, the user can use a whole lot of touches for a thousand miles. The good end may only move - small steps, or across the entire side control panel, == The standard is to move one whole. This is to allow the user to change the 'with the same finger movement time=two to step _ to select the cursor appearance for the sensitivity. 〇 ; =;,: on the screen _ to the new cursor position, and step =, 'that is the scale to wait for the next time before the update, the shortest time can be = 4 = = the target update time can be adjusted Received a new detailed description: At the host computer 4042, according to the new and old ^ = location, the amount of step shift. After obtaining the contact 』=== material to calculate the contact position deviation ==, after calculating the cursor offset 22nd guide to know the position data, proceed to step 4046 to calculate the new cursor position by using the current travel 200830163 target position and the cursor offset. Location data. "Set the new cursor fourth C picture according to the detailed description of step 408. After obtaining the new cursor position data and selecting the appearance of the cursor, the computer host first steps 働2 to determine whether it is the first, the cursor position, if Yes, the step position is taken from the storage pixel 攸buffer) (4). If otherwise, the current cursor position data of the step Nagrand is transferred to the memory of the mechanical graphic pixel, and then the surface is turned. Then (4) side The position of the cursor becomes the current cursor position, that is, the position of the cursor of Jing is covered (4), the position of the riding target is updated, and the memory of the pixel is updated. The pixel of the pixel is the display of the liquid crystal screen (LCM). The fifth figure is a flowchart of the operation of the touch panel according to the embodiment of the present invention. First, step 502 is performed to measure the actual coordinate range of the touch panel to obtain the actual touch panel. Effective coordinate range. Define the minimum actual coordinates: (TPMinX, TPMinY); Maximum actual coordinates: (TPMaxX, TPMaxY). For example: TPMaxX=3041, TPMinX=1133, TPMaxY=3320, TPMinY=1120. The coordinate conversion rate on the screen is calculated in step 504 relative to the coordinates of the touch panel. Definition: XRatio=(TPMaxX-TPMinX)/250; YRatio=(TPMaxY-TPMinY)/250. 200830163 Then proceed to step 506 cursor Initial display. First, set the initial cursor position CurrentX=100; CurrentY=100. Then, save the current screen data on the screen (100, 100), and then return to the original state. Then, on the screen (100, 100 The initial cursor is pulled out. Finally, the movement and update of the cursor in step 508 is performed, that is, the state of the touchpad is updated, the current actual coordinate value on the touchpad is obtained, and the actual coordinate point currently captured is determined. The relative position of the coordinates: (1) Grab the actual effective coordinate position XI, Y1 of the touch panel for the first time. (2) Grab the actual effective coordinate position X2, Y2 after moving again on the touch panel. 3) Calculate the position change of the current position (Χ2, Ύ2) and the initial position (X1, Y1) on the touchpad, and switch to the relative movement of the screen relative to the initial position (100, 100) of the cursor. Define:
DelaX=(-1)*(Χ卜X2)/XRatio;DelaX=(-1)*(Χ卜X2)/XRatio;
DelaY=(-1)木（Yl-Y2)/YRatio。 (4) 如果再次移動後的實際座標位置超過觸控板的實際可 以轉換的座標範圍，則回復成當前位置後回到（1)。 (5) 將螢幕上的游標應移動到的位置計算出來，定義： DrawX=CurrentX+DelaX;DelaY = (-1) wood (Yl-Y2) / YRatio. (4) If the actual coordinate position after moving again exceeds the actual convertible coordinate range of the touchpad, return to the current position and return to (1). (5) Calculate the position to which the cursor on the screen should be moved, defined as: DrawX=CurrentX+DelaX;
DrawY=CurrentY+DelaY 〇 n 200830163 ⑹將資料暫存區中前—個座標的資料傳到目前螢幕上游 “ ’即恢復絲上先前游標所在位置的原有狀態。 ⑺保存現在絲當前位置的狀態到資料暫存區中。 ⑻在發幕的當前位置（D而x，DrawY)上晝出對應的游標。 (9)重覆循環（2)~(8)。 第六圖是根據本發明實施例之游標的移動和更新流程 圖600。首先，步驟602清空觸控板暫存器中的座標數據； 再來步驟604抓取觸控板中的座標數·據（x_value， y一value);接著進行步驟606判斷是否在觸控板的有效座 標範圍内，若否則回到步驟6〇4 ,若是則進行步驟6〇8 抓取第一次落在觸控板上的實際座標（X1=x_value，DrawY=CurrentY+DelaY 〇n 200830163 (6) Transfer the data of the first coordinate of the data in the temporary storage area to the current upstream of the screen “'Restore the original state of the previous cursor on the wire.
