Description

[Detailed description of the invention] Display movable reference point control device Technical field The present invention relates to a movable reference point control device for a display. However, force actuated mechanical means and movement of the video display cursor are not permitted. and converting means for converting that force into an electrical signal used to control Ru.

Background technology In the following description, the terms reference point and cursor are used interchangeably. That's Ka hz even if the sensor contains more than a single pixel location of video display gray. The same shall apply.

Many types of cursor controls exist in the prior art. The key to the main computer system is - The keys routinely control the interpretation and position of the cursor. Even with key combinations, Direct control of the cursor's movement still increases at a 45 degree angle and at a relatively fixed rate. Usually, the interpretation is limited to the

The angle limit by controlling the key standard of the key & card is the same.

mouse home for mouse sticks, track goals and recent cursor controls. It has been improved. The Jiji Stick allows the Casa to move, and its movement This is an on/off control that specifies the direction. Zo, I stick type control is 90 degree interval , sometimes specifies movement of the 45 degree section cursor. Track goal, inverted mouse The shape and the mouse itself are not limited in angular direction or movement rate, but can be changed by the operator. Clear interpretive action is required. If the track is blank, the desired percentage will be detected. Manually rotate the email in the direction you want to generate the corresponding cursor effect. the other Vus is a model similar to a video display to generate the corresponding meaning of casa. create a natural area on which to request manual interpretation of the mouse structure.

Such prior art structure changes are subject to IBM Technical Disclosure. re Bulletin, Vol, 26, 47B, 3746-3747 page, published December 1983, and the key is Cursor control responds to logic combinations of each of the four keys at a 45 degree angle.

Figure 7 is a representative example of detecting the disk force and decomposing the force into perpendicular and vector values. FIG.

The device shown in FIG. The key containing ``1'' has a ``1''. There is a disk-shaped cursor control structure 3 there. is different from conventional ones in that the key is installed as an integral part with the key and the outer surface It is movable with respect to the plane of 4. Disc-shaped cursor control 3 applies force to it It is characterized in that it oscillates around the center point 6 of the disk axis. Preferably , the force supplied by the operator recovers the elasticity inherent in the structure of the casa control device. resist force. The cursor control device shown in the N1 diagram has a key in an assembly independent of the key 1. It is also quite possible to do so.

Figure 2 shows the features of an embodiment of this invention in which the disk 3 is attached to the key mate l. A typical structure shown is shown. Keyboard 1 includes a top surface 4 and a bottom surface 7. r i The shaft 11 of the disk 3 extends through the hole 8 in the upper surface 40 and is secured by a flexible O-ring 9. It is rotatably attached to the center of the hole 8. The axis 11 of the disk 3 is approximately in the middle of the hole 8. It only transmits lateral forces such as the oscillating force 12 around an axial point 13 located in the center. solid enough. The force 12 is a linear and nonlinear transverse solution at the base 14 of the axis 11. generate an interpretation or substitution. The shaft 110 base 14 is mounted at the center of the cross-shaped resilient members 16. The member 16 is attached to the lower surface 7 of the key and key 1 at its four ends (e.g. Two is 17. ls). Cross-shaped elastic member 160 of four arms According to this embodiment, each of the tension (tension gauge 19) and the force 12 of the disk 3 It includes a tension sensor that detects the corresponding compressive force (tension gauge 21). disk 12 Regardless of the location of force 12 relative to the 0 surface, the tension measurements in compression and tension are Decomposed into Cartesian coordinate vectors with a cross-shaped gauge/4-turn orthogonal structure . Similarly, K, the composite magnitude of force 12 is the tension and compression forces sensed by various tension gauges. can be measured relatively by

The movement of the video display cursor is non-linear with respect to the force acting on disk 3. It may be gender. Therefore, the O-ring 9, the elastic member 16, the shaft 11 and the disc 3 non-linear movements do not reduce the effectiveness of the device.

The orthogonal construction of the tension gauge with pairs of crossed patterns (Figure 5) is preferred for tension sensing. The gauges 19, 21 act complementarily along one axis. or, Such a structure lends itself to conventional bridge circuit sensing that responds to differential tension. .

For such a differential structure, the force is directed vertically downward along axis 11. It can be better understood by considering a normal situation. on 14 If a downward movement of the elastic member 16 in the near central region occurs, both tension gauges 19 ．． 21 detects tension.

Nevertheless, due to the differential sensing circuit, its output signal remains at approximately the value of O. It will be done. Similarly, the tension and compression forces in Figure 2 for tension gauge 19.21 are Detect that tension by moving it somewhat. But also, such a double tension gauge conventional Due to the structure of the bridge detection circuit, the total tension will be 0 bridge detection response. .

This principle is based on the bridge structure tension gauge quantity system, but this invention cursor control system to receive analog polar coordinate cursor movement commands. and the amplitude of the control force given by the operator. and was able to provide a low-cost structure that can be decomposed into Cartesian coordinates.

Figure 3 shows a slightly different mounting structure for the disk 3 on the upper surface 4 of the key. . In the previous structure, the key for disk 3 is inside the first card side, but this one The configuration is such that it appears above surface 4 of the keyboard. This structure fits into the recess of the keyboard. You can see that it prevents dirt from entering.

FIG. 4 follows the basic principle of the invention, but has a somewhat more specific structure. Figure 5 is It is shown in a sectional view taken along the line 5-5 in FIG. Disc-like structure 24 oscillates in response to force 12 The center point 23 in FIG. It is fixed to the surface 4. The thick, hard outer periphery of member 24 extends downwardly and has a diameter of 28°2. 9. Connect to the elastic member 27 through 31 and 32.

In the structure of Figs. 4 and 5, the presence of force 12 at point 1, for example, 330, is When the tension gauge 36 receives tension, the tension gauge 34 is subjected to compressive force, and the conventional Resistive tension gauges have resistors R5 and R4 decreasing and increasing in ohm value, respectively. So that the force is supplied in polar coordinates but is decomposed into vectors in Cartesian coordinates You must be careful.

FIG. 6 is a schematic diagram of another disk structure. here.

Four pressure-responsive sensors 37 arranged in pairs along the vertical axis are provided to detect the force 12. It senses the force and decomposes it into its own Cartesian coordinate size. This is also disk 3 O effectively rotates around the center point of the hole 8 in the surface 4 of the Figure 7 shows the video display control signal of force 12 (Figures 2 and 4) d- et al. Shows electronic circuit functions related to generation. Tension resistance R1/R2 and compression force resistance R3, respectively. The /R4 pair gives a Cartesian coordinate measurement of polar coordinates and is proportional to the magnitude of the force. Define force 12 as an analog signal. According to the preferred structure of this invention, The vector magnitudes of the signal and Y signals are calculated and then the phase of the cursor movement, e.g. Used to define relative speed or acceleration characteristics. Various measurements can be Preferably, it is substantially digitized before being used to drive the spray. So Moreover, rapid advances in digital sensor technology and the expanding use of digital signal processing Along with the analog tension and pressure sensor described here, the digital force sensing device It can be replaced by a functionally equivalent device such as
