Description

visual control system

The present invention relates to a view control system, in particular to a view control system for displaying scenes in a window frame.

In today's computer world, Windows-based APIs are widely accepted by computer users. When a certain application software uses a window program to display a scene graphic on a window frame (window frame), if the scene graphic is too large to be accommodated in the window frame, only part of the scene will be displayed on the window frame. Inside the window frame, at the same time, the window program will generate a scroll (scrolling bar) for scrolling the scene in the window frame on the right side or the bottom edge of the window frame. The part of the image displayed in the window frame is called a view, and the scroll wheel is used to scroll the view of the image graphic so that different parts of the image graphic can be seen through the window frame.

US Patent No. 5,530,455, invented by Gillick et al., discloses a mouse with a wheel for scrolling a view within a window frame. The up and down scrolling of the view is controlled by turning the wheel back and forth, while the left and right scrolling of the view is controlled by the wheel and a shift button. The speed and amount of scrolling of the visual scene are directly proportional to the speed and amount of rotation of the wheel. There are a number of disadvantages to using the scroll wheel of such a mouse to control the scrolling of the view. First, if you need to scroll through the view frequently, you may easily get tired or sore fingers from turning the wheel too often. Secondly, when the user needs two-dimensional scrolling, the user must often change the way the mouse is operated to change the scrolling direction, which is very inconvenient for the user. Furthermore, the up and down and left and right scrolling of the visual scene are all controlled by the forward and backward rotation of the runner. The forward and backward rotation of the rotary wheel causes the scene to scroll back and forth in a certain direction, which belongs to a specific interface control mode, and the user usually has to try it several times before he can become familiar with this specific control mode. When using this mouse, if the user must often switch between scrolling up and down and scrolling left and right, the same forward and backward rotation will produce different visual scrolling actions. Changing and adapting to different control modes can be difficult for the user.

The main purpose of the present invention is to provide a visual control system capable of simultaneously performing two-dimensional visual scrolling.

FIG. 3 is a block diagram of the scene control system 40 of the present invention. The visual control system 40 includes a screen 44 , a computer 42 electrically connected to the screen 44 , and a mouse 10 electrically connected to the computer 42 . The view control system 40 is used to control the display of the view 46 in the window frame 56 on the screen 44 . The scene 46 displays a part (dot area) of an image graphic 48 , and the image graphic 48 is a two-dimensional graphic stored in the computer 42 .

The computer 42 of the view control system 40 is used to display the view 46 in the window frame 56 on the screen 44 and control the scrolling of the view 46 so that different parts of the image graphics 48 can be viewed through the view 46 . The mouse 10 is electrically connected to the computer 42 . By using the ball, the left control knob 14 and the right button 16 of the mouse 10 , the user can control the movement of the cursor 54 on the screen 44 via the computer 42 . The user can also use the mouse 10 to generate a scroll signal to control the scrolling of the view 46 . The scroll signal is generated by the two-way button 18 and the view control button 24 of the mouse 10 according to the user's finger input, and they are used to control the scrolling of the view 46 of the image graphic 48 to make different parts of the image graphic 48 Can be viewed via view 46 .

The computer 42 includes a window software 52 for displaying and scrolling the view 46 in the window frame 56 , and a driver 50 for receiving the scrolling signal from the mouse 10 and transmitting it to the window software 52 . The window frame 56 includes a vertical scroll 58 and a horizontal scroll 60 for scrolling the view 46 vertically or horizontally. The window software 52 includes several service programs (routines) to provide various display control functions, and at least one application program is used to execute some specific functions according to the user's command input, such as editing the display screen 46 text or graphics.

FIG. 4 is a cross-sectional view of the view control button 24 of FIG. 1 along the line I-I. FIG. 5 is another cross-sectional view of the view control button 24 being pressed sideways by a finger. The view control button 24 is a sensor used to sense a two-dimensional direction signal input by each finger, and the mouse 10 generates a two-dimensional scrolling signal according to each sensed direction.

The visual control button 24 includes a plurality of sensing elements 66 arranged on the circuit board 62 of the mouse 10 for sensing the direction of each finger input, and a touch pad 68 arranged on the sensing element 66 for use as a finger input interface. When the touch pad 68 accepts finger input, it can be inclined to a certain direction within a fixed angle according to the force of the finger, so that the direction of the finger input can be sensed by the sensing element 66 through the change generated by the touch pad 68 to and converted to a scrolling signal via the mouse 10.

The sensing elements 66 are made of conductive copper wires disposed on the circuit board 62 and are electrically connected to the control unit 28 , and are arranged in approximately concentric circles under the touch pad 68 . The touch pad 68 includes an elastic and conductive convex surface 70 for contacting the sensing element 66 . The sensing element 66 may be used to measure the pressure exerted by the finger 64 or the tilt angle of the touch pad 68 caused by the finger 64 . The pressure input by each finger 66 can be determined by measuring the number of sensing elements 66 contacted by the elastic convex surface 70 , and then the control unit 28 of the mouse 10 converts it into a scrolling signal. The tilt angle generated by each finger input can also be determined by detecting the outermost one of the sensing elements 66 in contact with the touch pad 68 and converted into a scrolling signal by the control unit 28 of the mouse 10 . The force or tilt angle measured by the sensing element 66 can be used to control the scrolling speed of the view 46 in the window frame 56 . FIG. 5 shows the tilting of the elastic convex surface 70 of the touch pad 68 under the pressure of the finger 64 , which causes the several sensing elements 66 to be contacted by the touch pad 68 . The greater the force exerted by the finger 64 , the greater the number of sensing elements 66 that are contacted by the elastic convex surface 70 . The outermost sensing element 72 contacted by the touch pad 68 can be used to measure the tilt angle of the touch pad 68 .

The scroll signal received by the driver 50 includes at least four parameters: Δx, Δy, Δs and F. The parameter (Δx, Δy,) represents the normalized vector of the two-dimensional direction of the finger input. The length of the vector is always equal to 1, and the value of the parameter Δx or Δy, Δs is between +1 and -1. Δs is a zooming parameter, representing that the front end 20 (zoom in) of the two-way button 18 is pressed by the user (Δs=1) or the rear end 22 (zoom out) of the two-way button 18 is pressed by the user (Δs=−1). F represents the pressure input by the finger or the tilt angle generated by it. If no finger input is received by the view control button 24, the parameters Δx, Δy and F will all be zero. And if any end of the two-way button 18 is not pressed by a finger, Δs will also be 0. Each scrolling signal is generated by the mouse 10 within a predetermined time interval according to the finger input (resolution), so the longer the key-press time of a finger input is, the more the number of scrolling signals generated by the mouse 10 is. , the window software 52 will scroll the view 46 in the window frame 56 according to each received scroll signal. This design makes fingers not need to keep moving in order to continuously scroll the view 46 in the window frame 56, so it is very labor-saving.

Please refer to Figure 6 to Figure 8. When displaying the view of a larger image graphic, the window software 52 will automatically generate one or two scrolls that are used to control the scrolling of the view in the window frame. If its vertical size and horizontal size of the displayed image graphics are all greater than the visual field size displayed in the window frame, then the window software 52 will set a vertical scroll and a horizontal scroll on the right and bottom of the window frame, as shown in Figure 6 The window frame 80 shown includes a vertical scroll 82 and a horizontal scroll 84 . In this case, the window software 52 will scroll the scene according to each parameter of the scroll signal. That is to say, if the parameters Δx, Δy and F are not 0, the window software 52 will scroll a scene displayed in the window frame 80 in the direction of (Δx, Δy) at a speed proportional to F. Similarly, if the parameter Δs is not 0, the window software 52 will also zoom in or out the contents of the view according to the parameter Δs until a predetermined boundary condition is reached.

In addition, if only one size of an image graphic is larger than the relative size of the view, Windows 52 will only generate one scroll. FIG. 7 shows a window frame 86 including a vertical scroll 88 , while FIG. 8 shows a window frame 90 including a horizontal scroll 92 . Under these circumstances, the Windows software 52 will react differently to the scrolling signal received from the mouse 10 .

In the situation shown in FIG. 7, since only the vertical scroll 88 is displayed, the window software 52 does not need to scroll the view in the horizontal direction, even if the parameter Δy is not equal to zero. In this state, the window software 52 will scroll the view in the vertical direction according to the parameter Δx and ignore the parameter Δy. In the situation shown in FIG. 8 , because only the horizontal scroll 92 is shown, the window software 52 will scroll the scene in the horizontal direction according to the parameter Δy and ignore the parameter Δx.

The parameter Δs can also be handled differently in different display situations. When editing an image graphic, the window software 52 can be restricted to only zoom the view of the image graphic at the same speed along the vertical and horizontal directions so that the displayed graphic content will not be deformed. When editing text images, this restriction can be canceled. This is because the vertical or horizontal scale change of the character image usually does not affect the recognition of individual characters. The application software manufacturer should be able to decide which application software should provide the user with the choice of proportional change under different circumstances.

The following is a preferred embodiment of the view scrolling and zooming program executed by the window software 52 . It shows how the windows software 52 responds to scrolling signals in different situations. In this kind of program, the visual scene displayed by the window software 52 is treated as a graphic image, so when the zoom function is executed, the window software 52 will enlarge or reduce the visual scene in the vertical and horizontal directions with the same ratio to make the graphics The content will not be deformed, and its execution steps are as follows:

Step (1) receives a scrolling signal from the driver 50;

Step (2) checks whether the two-way button 18 is pressed (Δs=0); if not then to step (4);

Step (3) enlarging or reducing the content of the scene in the vertical and horizontal directions according to a predetermined ratio simultaneously according to the Δs parameter;

Step (4) check whether the view control button 24 is pressed (Δx=Δy=F=0); if not pressed, then go to step (9);

Step (5) If only the vertical scroll is displayed on the window frame, set Δdy=0 and calculate the moving distance Δdx of the visual scene on the image graphics, Δdx is proportional to the parameters Δx and F; to step (8)

Step (6) If only the horizontal scroll is displayed on the window frame, set Δx=0, and calculate the moving distance Δdy on the scene image graphics, Δdy is proportional to the parameters Δy and F; to step (8);

Step (7) If the vertical and horizontal scrolls are simultaneously displayed on the window frame, then calculate the moving distances Δx and Δy of the visual scene on the image, Δdx is proportional to the parameters Δy and F; and Δdy is proportional to the parameters Δy and F;

Step (8) Obtain a new view on the image graph according to the moving distance Δdx, Δdy, and display the new view on the window frame;

Step (9) ends the program.
