Since sound is output, it is possible to perform accurate input operations without having to constantly look at both the screen of a display device such as a CRT display and the numerous keys of a human-powered device, improving operability. In addition, it is possible to determine whether the cursor is moving or not and whether the cursor is positioned at the farthest edge of the displayed selection object without looking at the screen.

[Conventional technology]

Various types of signal input means for remote control systems, microcomputers, etc. are known, one of which uses a screen display.

This involves setting a window on the screen of a display device such as a CRT display, displaying multiple selection targets and a cursor within this window, and then moving the cursor to the desired selection target position according to instructions from an input device. While moving the object, the desired selection object is selected using an input device. As for this human-powered device, a key human-powered device is used for boat fishing.

[Problem to be solved by the invention]

In the above-mentioned key-powered device, each key has one function; for example, two keys are required to move the cursor upward and downward, so the screen of the display device and You cannot operate it unless you are looking at your hands.

In other words, when selecting one of multiple selection targets using the screen display, accurate input operations cannot be performed unless you are constantly looking at both the display screen and the many keys on the keypad. However, there were some difficulties in operability.

Therefore, an object of the present invention is to provide a control system that can significantly improve operability.

[Means to solve the problem]

The control system according to the present invention includes a plurality of selection targets, a display means for displaying a cursor for indicating the selection targets, an input means for defining the movement direction and amount of movement of the cursor,
an identification means for determining movement of the cursor between selection objects displayed on the display means and movement of the cursor beyond the range of selection objects displayed on the display means; a first sound is generated when the cursor moves between selected objects displayed on the display means, and a second sound is generated when the cursor moves beyond the range of selected objects displayed on the display means; and a sound generating means controlled based on the output from the identifying means.

[Effect]

A plurality of selection targets and a cursor are displayed on the display means.

By operating the input means, the direction and amount of movement of the cursor are defined, and the cursor is moved to the position of the desired selection target.

During movement of the cursor, the state of movement of the cursor is determined by the identification means, and different sounds are output from the sound generation means depending on the state of movement. That is, while the cursor is moved within the range of the selection target displayed on the display means, the first sound is output, and when the cursor is moved beyond the range of the selection target displayed on the display means. If you try to move it, a second sound will be output.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In this embodiment, the present invention is applied to a system that remotely controls a television device and controls other equipment via a microcomputer provided in the television device.

FIG. 1 shows the configuration of a commander for remote control, in which symbol 2 indicates a roller section, and 2 indicates a switch provided in association with the roller section 1, such as a tact switch. As shown in FIGS. 2A and 2B, the roller section 1 includes a roller 1a that is rotatably supported by a case 10 by a shaft 11 and whose peripheral surface protrudes from the upper surface of the case 10. . The shaft 11 is made of a rod-shaped spring, and when the roller 1a is pushed down, the switch 2 is turned on via the auxiliary plate 12.

As will be described later, the roller 1a has a function as a pointing device for selecting a menu displayed on the screen or a control command, and a function for inputting a control amount when a control command is selected.

Further, although not shown in the drawings, the roller section 1 is provided with a rotation detector that generates a detection pulse signal in accordance with the rotation of the roller la. More specifically, the detection pulses SA and SB are generated by a rotary switch, a magnetic detector consisting of a magnet and a Hall element, or an optical detector consisting of a light emitting element, a light receiving element and a rotating slit plate.

Further, the case 10 is provided with a commander power switch indicated by 13. A remote control signal in the form of modulated infrared rays is transmitted from the end surface 14 of the case 10. As shown in FIG. 2C, the commander may be provided with a display section 16 such as a liquid crystal display, and the roller 1a may be operated without looking at the display on the display section 16.

FIG. 3 shows two-phase detection pulses SA and SB generated in response to the rotation of the roller 1a. The phase relationship between the detection pulses SA and SB indicates the rotation direction of the roller 1a, and the number of generated pulses indicates the amount of rotation of the roller 1a. The number of detection pulses SA and SB is a predetermined number per rotation of the roller 1a, and the frequency thereof is proportional to the rotation speed.

As shown in FIG. 3, the rising edge of the detection pulse SA is
The phase relationship that occurs before the rise of the detection pulse SB means that the roller 1a is rotated in the direction of arrow A. Rotation of the roller 1a in the direction of arrow A corresponds to moving the cursor upward on the tube surface.

On the other hand, when the roller 1a is rotated in the direction of arrow B, the rise of the detection pulse SB is before the rise of the detection pulse SA. Rotation of the roller 1a in the direction of arrow B corresponds to not moving the cursor downward on the tube surface. Furthermore, the rotation amount of the roller 1a is determined by one detection pulse,
For example, it can be detected by counting the number of SAs.

The detection circuit 3 detects detection pulses SA and S having the above-mentioned relationship.
The direction and amount of rotation are detected from the signal B, and, for example, 2-bit code signals P1 and P2 are generated.

The detection circuit 4 generates a 2-bit code signal P3 indicating that the roller 1a is pushed in the direction of the arrow C from the pulse SC corresponding to the on/off of the switch 2.

As an example, code signal P1 indicating upward movement is (0
1), the code signal P1 indicating downward movement is set as (10), and the code signal P3 indicating that the roller 1a is pushed in is set as (11). The amount of rotation is expressed by the number of code signals P1 and P2. The number of bits of the code signal is not limited to 2 bits, but may be other numbers such as 4 bits.

Code signals P1, P2 and P3 from detection circuits 3 and 4
is supplied to a remote control code encoder (hereinafter abbreviated as encoder) 5.

The encoder 5 converts the code signals P1, P2, and P3 into remote control signals in a predetermined format, and this remote control signal is supplied to the transmitting circuit 6.

The transmitting circuit 6 is provided with a light emitting diode and its driving amplifier, and a remote control signal converted into an infrared signal is emitted from the transmitting circuit 6 toward the television device.

FIG. 4 shows the configuration of a television device as a receiving device.

In the receiving circuit 21, a remote control signal converted from an infrared signal to an electric signal is sent to a remote control code decoder (
(hereinafter abbreviated as decoder) 22.

The decoder 22 decodes the received remote control signal into code signals corresponding to the direction of rotation, the amount of rotation, and the push of the roller.

The code signal from this decoder 22 is supplied to the CPO 23.

According to the program stored in the ROM24, the CP
U23 supplies control signals to the display control circuit 25, the superimposing device 26, the sound generating device 51, the controlled object 29 inside the device, the transmitting circuit 3o, and the bus output terminal 31. In this example, the controlled object is a circuit associated with a television device.

Further, in the superimposing device 26, the cursor information from the display control circuit 25, the RGB signal indicating the state of the roller, etc., and the input RGB signal from the input terminal 27 are combined, and a combined image signal is taken out at the output terminal 28. . This composite image signal is connected to the output terminal 28 of a C
Supplied to RT display.

The transmitting circuit 30 generates a remote control signal in the form of an infrared signal, and is provided to remotely control another device, such as a VTR.

The television device also includes a roller section 41 and a switch 42.
is provided. A detection pulse from the roller section 41 is supplied to a detection circuit 43, and a detection signal from the switch 42 is supplied to a detection circuit 44.

Output signals from detection circuits 43 and 44 are supplied to CPU 23, respectively. This input device has the same configuration as that provided in the above-mentioned commander, and its explanation will be omitted.

Note that 52 is a speaker.

The roller 41a is provided on the front panel of the television device, as shown in FIG. 21a is a light receiving section of the receiving circuit 21, 30a is a light emitting section of the transmitting circuit 30, 45 is a tube surface on which an image is displayed, and 46 is a power switch.

The irradiation direction of the light emitting section 30a can be adjusted to any direction.

In the embodiment described above, when the roller 1a is pushed in while the television device is powered on, a menu screen is displayed on the screen 45. In this case, the menu screen may be displayed by pressing the roller 1a twice in a very short period of time, or by double-clicking.

The menu screen is used to specify switching of the video input of the television device, to select the television device or an external device as the device to be controlled, and to select the content of control of the television device.

The control contents of the television device include daily control contents such as channel switching and volume adjustment, and adjustment contents such as screen brightness. The control contents used on a daily basis may be displayed by pushing the roller 1a before the adjustment contents.

Below, using the channel switching described above as an example, roller 1
The content of generating sound according to the movement state of the cursor using a as a pointing device will be explained.

For example, when Eva selects the channel switching menu by moving the cursor by rotating the roller 1a and pushing the roller 1a, a display screen 45C shown in FIG. 6C appears on the tube surface 45.
appears. That is, in the menu screen, roller 1a
When the cursor is moved by the rotation operation and the roller 1a is pushed in to match the channel switching menu to be selected, a display screen 45C for channel switching appears on the screen 45, as shown in FIG. 6C. appear.

The display screen 45C has display blocks 53a to 53f on which channel numbers are displayed arranged vertically. Further, a display block 53g for returning to the previous page is provided.

As shown in FIG. 6C, the cursor 47 indicated by diagonal lines in the display block 53a moves from the display block 53a of the first channel to the display block 53d of the fourth channel on the tube surface by the rotation operation of the roller 1a. 45, the CPU 23 moves the cursor 47 displayed on the display screen 45C based on the code signal from the decoder 22 described above.

The CPU 23 knows the display position, amount of movement, and movement direction of the cursor 47 at each point in time, and based on the state of movement of the cursor 47, generates, for example, a 2-bit sound generation signal S.
0 and supplies it to the sound generator 51.

The above-mentioned 2-bit sound generation signal SO has the states (00), (
It can take four states: 01), ('10), and (11), and the sound generating device 51 generates a predetermined sound corresponding to each state. For example, in state (00) there is no sound, in state (01) a short sound such as a beep is generated, and in state (10
), a long beep sound is generated for a predetermined period of time, and the state (1
In 1), a sound such as a beep is generated for a predetermined period of time.

As described above, when the cursor 47 sequentially moves from the display block 53a of the first channel to the display block 53d of the fourth channel by the rotation operation of the roller 1a, the C'PU 23 receives the code signal from the decoder 22. Based on this, a sound generation signal SO in state (01) is formed and supplied to the sound generation bag W51. Therefore, in this case,
Each time the cursor 47 moves between the display blocks of each channel, a short beep, beep, etc. is generated.

The cursor 47 is on the display block 53d of the fourth channel.
When the rotation operation of the roller 1a is stopped at the stage when the
The CPU 23 forms a sound generation signal SO in state (00) based on the code signal from the decoder 22 and supplies it to the sound generation device 51.

Therefore, in this case, the cursor 47 reaches the display block 53d of the fourth channel, generates a short sound such as a ping, and then becomes silent.

Next, when the cursor 47 moves upward on the tube surface 45 from the display block 53d of the fourth channel to the display block 53a of the first channel by the rotation operation of the roller 1a, the CPU 23 performs the same operation as in the above case. A 2-bit sound generation signal SO is formed and supplied to the sound generation device 51.

The cursor 47 is on the display block 53d of the fourth channel.
to the display block 53a of the first channel, sequentially.
When moving, the CPU 23 forms a sound generation signal SO in state (01) based on the code signal from the decoder 22 and supplies it to the sound generation device 51. Therefore, in this case, each time the cursor 47 moves through the display block of each channel, a short beep, beep, - is generated.

The cursor 47 is on the display screen 53a of the first channel.
When the rotation operation of the roller 1a is stopped at the stage when the
The CPU 23 forms a sound generation signal SO in state (10) based on the code signal from the decoder 22 and supplies it to the sound generation device 51 for a predetermined period of time. Then state (00)
The sound generation signal SO is sent from the CPU 2.3 to the sound generation device 5.
1.

Therefore, in this case, the long beep sounds for a predetermined period of time.
After being generated, there will be silence.

The reason why the sound generation signal SO in state (10) is supplied for a predetermined period of time is because the first channel is located at the upper display block 53a among the displayed channel numbers. . Similarly, when selecting the channel number located at the bottom of the channel number that is not detailed, the state (10
) is supplied for a predetermined period of time, then the sound generation signal SO in state (00) is supplied.

Then, when the roller 1a is further rotated to move the cursor 47 upward from the display block 53a of the first channel, the CPU 23 generates a sound in state (11) based on the code signal from the decoder 22. Signal S
0 is formed and supplied to the sound generating device 51 for a predetermined period of time.

After that, the sound generation signal SO in the state (00) is supplied.

Therefore, in this case, the long beep sounds for a predetermined period of time.
After being generated, there will be silence.

As described above, the sound generation signal SO in state (11) is supplied for a predetermined period of time when the first channel among the displayed channel numbers is located at the upper end display block 53a, and no more. This is to notify that the cursor 47 cannot be moved upwards on the tube surface 45. Similarly, when selecting a channel number located at the bottom of a channel number not described in detail, after the sound generation signal SO in state (11) is supplied for a predetermined period of time, the sound generation signal SO in state (00) is selected. is supplied.

In this way, different sounds are output in response to the movement of the cursor 47 displayed on the screen, so unlike the conventional CR
Accurate input operations can be performed without constantly looking at both the screen of a display device such as a T-display and a large number of keys, and operability can be improved.

Furthermore, it is possible to judge whether the cursor 47 is moving or not and whether the cursor 47 is positioned at the farthest edge of the displayed selection target without looking at the screen.

In the case of a wireless remote control device, if the signal is not transmitted correctly even if the signal is sent to the system, no sound will be output, so the connection between the remote control device, the system, or the remote control device and the system It turns out that a problem has occurred in one of them.

Next, adjustment of the television device will be explained.

When the cursor 47 is moved with the roller 1a to select the adjustment content menu and the roller 1a is pushed in, a display screen 45A shown in FIG. 6A appears on the tube surface 45. Display screen 45A
A plurality of display blocks each consisting of a display of control contents and a display of the control amount are vertically arranged.

In the illustrated example, the hue control (the range of the control amount is −
31 to +32), color control (control amount range is 0 to 63), brightness control (control amount range is 0 to 63), picture (brightness level) control (control amount range is 0 to 63), sharpness control A display block for (the range of the control amount is -31 to +32) is provided, a display block for resetting each control amount to its initial value, and a display block for returning to the previous page.

- For example, when performing Hue control, use the roller 1a to align, for example, a red cursor 47 to the position of the Hue control display block. The background color of other display blocks is white. Then, when the switch 2 is turned on by pushing the roller 1a, the function of the hue control can be selected. At this time, as shown in FIG. 6B, the cursor 47 blinks on the tube surface, and the roller 1a
A mark 48 appears indicating that the pointing device function has been changed to the control amount input function.

This blinking of the cursor 47 and the mark 48 indicate 0-la 1.
It is obvious at a glance that the function of a has changed. Of course, changes in the function of the roller 1a may be displayed using shapes, colors, marks, etc. other than those shown.

When the roller 1a is rotated upward without looking at the display screen 45B in FIG. At the same time, the numerical value on the display screen 45B also increases in accordance with the signal. When the roller 1a is rotated downward, a control signal that decreases the numerical value is generated, and the numerical value on the display screen 45B also decreases. Adjustments other than hue control can be made in the same way by only operating the roller 1a.

Furthermore, by selecting the display block on the previous page with the roller 1a and pushing the roller 1a, the display screen 45D for controlling the VTR is moved to the tube surface 4, as shown in the sixth diagram.
5 can be displayed. On the display screen 45D, display blocks corresponding to VTR operations such as playback, recording, and fast forward are arranged vertically. Select a desired display block by rotating the roller 1a, and push the roller 1a to select the desired display block. A remote control signal corresponding to the operation is provided from the transmitting circuit 30 to the VTR.

Further, the VTR sends a return signal indicating the operating state to the television apparatus as an infrared signal. With this return, the operating status of the external VTR can be displayed on the display screen 45D.

In this case, in the case of a configuration in which no return is performed, the cursor changes color or blinks on the display screen 45D only while the remote control signal is being sent from the transmitting circuit 30, and after the remote control signal is sent, , the original display is returned.

In the above embodiment, an example in which the cursor is moved in the vertical direction has been described, but the present invention is not limited to this, and the cursor may be moved in the left-right direction in accordance with the movement of the roller. In that case, displays indicating the objects to be controlled are arranged horizontally on the tube surface. Of course, the cursor may be moved diagonally.

Also, for those who do not have a CRT display,
As in the example shown in FIG. 2C, since the commander has a display section, it is possible to perform the same control as in the above embodiment.

In the embodiment described above, the cursor 47 is displayed by changing the color of the display block, but the present invention is not limited to this, and for example, the cursor 47 may be displayed as an arrow.

〔Effect of the invention〕

According to the control system according to the present invention, different sounds are output in response to the movement of the cursor displayed on the screen. This has the effect that accurate input operations can be performed without looking at both keys at all times, and operability can be improved.

In addition, it is possible to determine whether the cursor is moving or not, and whether the cursor is positioned at the farthest edge of the displayed selection target.
This has the advantage that it can be done without looking at the screen.

In the case of a wireless remote control device, if the signal is not transmitted correctly even if the signal is sent to the system, no sound will be output, so the connection between the remote control device, the system, or the remote control device and the system It turns out that a problem has occurred in one of them.
