Industrial applications The present invention relates to a conversational information processing system, especially a hand-held input device. The rotational movement and lateral movement of dheld 1nput devlce) -sols, paint plans, pointers, pixel (digital) images and graphic objects If you want to edit or control the display information by controlling two view display information such as objects, related to the system.

Background of the invention computer graphics painting and line drawing processing system; The user controls the ``sole'' by operating a hand-held input device. You can edit information on your computer screen. Screen information meeting Speech control is performed using a paint or drawing software program (drawSoftware). Mouse input that is partially embedded or not embedded in ftwareprogram) Obtained by subsystems. The mouse input subsystem allows for hand-held input. The movement of the force device can be achieved by a mechanical, photoelectrically sensitive, electromagnetic or electronically sensitive mechanism. Detect across flat surfaces. For example, mouse, hand cursor/tablet A hand-held input device, which can be a tablet or stylus/tablet, can be a cursor, Pointer, paintbrush, pixel image bitmap or drawing object calculate the information used to move the object and then paint or draw a line on this information. The shape of the software program sends a mouse interface related to the degree of movement. Send data.

The mouse data entry system is generally illustrated in FIG. You can naturally enter data into a computer conversationally. Such a scene The stem typically includes a handheld input device 10 and a mouse interface. and a cursor, pointer or graphics processing object 12 on the display screen 14 or The cursor drive circuit that controls all of this and the mouse/device position and software that sends parameters to the application program. flat surface Movement of the hand-held input device 10 across causes the cursor on the display screen 14 to 12 or change the variables of the computer application program. this data The input system allows the user to point out on the display screen or run the application program. rows can be influenced.

At Baynton Stems, the aforementioned "tools" typically include a computer display screen. It is a paint brush that moves across and edits the information displayed on the display screen. , display screen according to paintbrush shape and current and previous paintbrush position. Edit the information displayed cleanly. For example, as shown in Figure 2, a typical An intosystem is a system that traverses a flat surface with a fixed shape, such as a line or a rectangle. A paint block that can be moved around the screen by cutting and moving the mouse. Show Rashi. As this brush moves across the screen, this system Pixels 16 (small colored or illuminated elements that together make up the screen image) Edit the screen by changing the color or intensity values of the screen. Each pixel 1 6 is located at a position considered to be the path along which the plan moves. This diameter The path is from the tip of the brush image at the current position 20 to the brush at the previous position 22. Generates a straight line or curve 18 to the tip of the image and connects the current and previous images of the brush with line 1 This can be determined by partitioning the area 24 surrounded by 8 and 8. Or a brush It is sufficient to simply print at each contact position. Passed by paint brush λ Regular users can edit the paintbrush screen by pressing a button on the mouse. The concentration effect can be produced or deactivated.

In line-drawing graphics processing systems, the cursor or pointer is It is used to create, identify, move, or change graphical objects in an object. this Shape-pair processing objects such as regular lines, polylines, rectangles, circles, ellipses, and Consists of display elements that are text. For example, a polyline is represented entirely by its vertices. The line-drawing graphics processing system therefore produces a permanent representation of the polyline. You only need to identify each vertex of the polyline. move or change polylines Whenever needed, the system simply moves or changes the vertices of the polyline. Draw a new polyline using the new vertices.

The drawing graphics processing system uses the mouse input subsystem to generate movement forces on the screen. Create, select, and change objects using the mouse cursor and buttons. I can do it. When you select an object, this object is displayed with or under the cursor. can be moved instead of a sol, or its shape, i.e. its vertices or other The associated parameters can change with or instead of cursor movement.

Currently, computer graphics processing paint line drawing graphics processing systems allow users to relative to the x and y coordinates of the device when moving it across a flat surface. Only related variables can be directly controlled. Therefore, the user can determine the location of the device. You can only change the information on your computer screen by changing the be. In these systems, the user can rotate the motion sensing device to Paint plans, cursors, pointers, or graphics objects or pixel diagrams The orientation of the figure cannot be controlled rotationally.

The conversational painting and drawing graphics processing system moves the motion sensing device in a circular motion. Make the screen cursor draw an arc around the center of the object When graphic processing objects and text can be rotated indirectly by exists in In these systems, changes in object orientation are , the cursor and the rotating object when the cursor position is relative to the position of the motion sensing device. related to changes in the slope of the line connecting the center of the object. A 7 stem work like this The application is illustrated in FIG. 6 and is described in U.S. Pat. It is described in the specification of No. 05. These methods work indirectly, so their effectiveness is Gender is suboptimally compatible. For example, these existing systems The button does not cause a rotational action and a simultaneous change in the position of the object. Also, indirect action is redundant. These systems are not compatible with rotating cursors and paint plans. cursor and paint plan angle options for the current paint drawing system. Reorientation is fixed during painting and cursor movement operations.

The rotating paint plan allows the user to explore the real world. What can happen in case d) (i.e. using an actual paintbrush on paper) It is even more effective! (You can selectively edit the screen.
