  Conventional audio equipment mainly uses a rotary resistor to adjust volume and left / right balance. However, since the resistance is changed by moving the contact in the rotary resistor, there is a problem that the contact is worn due to its mechanical structure.

  On the other hand, recent audio equipment includes a remote controller for performing various operations from a distance, and volume adjustment and balance adjustment can be performed by pressing a button provided in advance on the remote controller. . In this method, for example, when the volume is increased, only the UP button is pressed, and when the volume is decreased, the DOWN button is simply pressed. Therefore, problems such as deterioration of the resistor can be avoided.

  Further, according to the present invention, the position information of the finger on the track pad is decomposed into the respective axial components orthogonal to each other, and the command signal for controlling the device is generated based on the respective axial components. By simply changing the position of the finger on the trackpad, a plurality of controls can be executed simultaneously.

  The remote controller, the remote control system, and the remote control method of the present invention have the following effects.

  The first effect of the present invention is that an acoustic device can be controlled quickly and accurately with an analog sense as in the case of rotating a resistor.

  The reason is that the remote controller includes a trackpad and an arithmetic processing unit. The arithmetic processing unit calculates a rotation angle centered on a predetermined position based on the position information of the finger on the trackpad, and calculates the rotation angle. Generates a command signal for controlling the audio device based on it and sends it to the audio device, so it is possible to quickly control volume adjustment and left / right balance adjustment compared to the method of pressing a button, Since the amount of change can be changed according to the distance between the fulcrum and the moving point, compared to the method of controlling according to the moving amount on the trackpad, volume adjustment and left / right balance adjustment etc. This is because control can be performed.

  The second effect of the present invention is that a plurality of controls of the audio equipment can be executed simultaneously.

  The reason is that the position information of the finger on the track pad is decomposed into each axial component such as the X axis and the Y axis, and a command signal for controlling the device is generated based on each axis component. This is because two or more controls can be executed simultaneously by simply changing the position of the finger on the trackpad.

  In addition, the third effect of the present invention is that the control of the audio equipment can be easily executed in detail.

  The reason for this is that by placing multiple fingers on the trackpad at the same time, the number of fingers that have a different meaning that is not decomposed into axial components can be recognized. This is because it can be easily switched to the next level.

  In a preferred embodiment of the remote controller of the present invention, the track pad that detects the position information of the finger on the pad, the position information of the first finger on the track pad, the start point and the end point of the second finger. An arithmetic processing unit that calculates a rotation angle around the first finger based on the position information and generates a command signal for performing control such as volume adjustment and left / right balance adjustment of the audio device based on the rotation angle And a remote control signal generator that modulates and amplifies the command signal to generate a remote control signal, such as when rotating a resistor while preventing occurrence of problems due to contact wear and the like The audio equipment can be controlled quickly and accurately with an analog sense.

  In order to describe the above-described embodiment of the present invention in more detail, a remote controller, a remote control system, and a remote control method according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a diagram schematically showing the configuration of the remote control system of this embodiment, and FIG. 2 is a diagram showing the main means and signal flow of the remote controller and the audio equipment. FIG. 3 is a diagram schematically showing the movement of the finger on the track pad, and FIG. 4 is a diagram showing a method for detecting the rotation angle. FIG. 5 is a diagram illustrating an example of a screen displayed on the display unit of the audio device.

  As shown in FIG. 1, the remote control system 1 of the present embodiment controls an audio device 2 such as a television or a player having a sound output function, and controls such as volume adjustment and left / right balance adjustment of the audio device 2. The remote controller 3 is made up of, for example, static electricity, pressure, light, etc., in addition to button-type operation means such as the power switch 4, function selection button 5, and channel switch 7. A track pad 6 for detecting position information of an indicator such as a finger (hereinafter referred to as a finger) is provided, and various functions of the acoustic device 2 are performed by infrared rays, ultrasonic waves, weak radio waves, etc. transmitted from the remote control signal transmitter 8. Is controlled.

  Moreover, FIG. 2 is a figure which shows the main means relevant to control of a present Example among the means with which the remote controller 3 and the audio equipment 2 are provided. As shown in FIG. 2, the remote controller 3 includes an arithmetic processing unit 9 including an arithmetic circuit and a command signal generating circuit, a remote control signal generating unit 10 including a modulator and an amplifier, and the like. In the acoustic device 2, a remote control signal receiving unit 11 including a receiver and a demodulator, a display unit 12 for displaying various information, a sound source control unit 14 including an amplifier and the like, 13 and a speaker 15 are provided.

  1 and 2 are merely examples, and the acoustic device 2 may be any device that can control at least one operation using the remote controller 2, and the type and form thereof are not particularly limited. The remote controller 3 only needs to include at least the track pad 6 and the arithmetic processing unit 9, and the configuration and form of other parts are arbitrary. In this embodiment, the volume control and the left / right balance adjustment are shown as operations that can be controlled by the remote controller 2, but the present invention can be similarly applied to the case of controlling other operations.

  Here, the track pad 6 has been conventionally used as an input means for a personal computer or the like. Normally, the track pad 6 realizes processing according to the movement amount (that is, distance) of the start point and end point of the finger on the pad. I just did. On the other hand, in the present embodiment, the arithmetic processing unit 9 allows the track pad 6 to be operated with the same feeling as when the conventional volume control (rotary resistor for volume adjustment) is turned. Based on the position information of the fulcrum and the position information of the starting point and the end point of the moving finger, a rotation angle about the fulcrum is calculated, and processing according to the rotation angle can be realized.

  Referring to FIG. 2, first, the position information (X-axis and Y-axis coordinates) detected by the track pad 6 is sent to the arithmetic processing unit 9, and the rotation angle is calculated based on the position information by the arithmetic circuit. The command signal generation circuit generates a command signal such as volume adjustment based on the rotation angle. Then, the generated command signal is sent to the remote control signal generator 10, modulated, amplified, and transmitted as infrared rays, ultrasonic waves, or weak radio waves. On the other hand, the remote control signal receiving unit 11 of the acoustic device 2 receives and demodulates the transmitted remote control signal, and then transmits the remote control signal to the display unit 12 and the acoustic control unit 14. Then, the sound control unit 14 amplifies the signal transmitted from the sound source 13 at a volume defined by the command signal and causes the speaker 15 to ring.

  For example, as shown in FIG. 3A, two fingers (for example, thumb and index finger) are placed on the track pad 6, and one finger (for example, thumb) is not moved, while the other finger (for example, for example, thumb) Move the index finger) to draw a circular arc from the left side to the right side of the figure. Then, the thumb position information and the position information of the start and end points of the index finger are detected by the X / Y coordinates of the track pad 6, and the position of the thumb is centered on the basis of the respective coordinate values of the X / Y axes. A rotation angle is calculated, and a command signal is generated based on the rotation angle.

More specifically, as shown in FIG. 4A, the X / Y coordinates of the thumb position (point A) are (Xa, Ya), and the X / Y coordinates of the starting point (point B) of the index finger are (Xb1 , Yb1), where the X / Y coordinate of the end point (point B ′) of the index finger is (Xb2, Yb2), the length d of the straight line connecting B and B ′ is ((Xb2−Xb1) ² + (Yb2−). Yb1) ² ) ^1/2 . Here, when this length d is approximated as the length of the arc of B → B ′, the rotation angle α is the distance between the thumb and the index finger (for example, the distance of a straight line connecting A and B or A and B ′, or The average) and the length d can be used for calculation. Then, the calculated rotation angle is associated with the rotation angle of the rotary resistor (the calculated rotation angle and the rotation angle of the rotary resistor are not necessarily matched), and the volume adjustment amount or Sets the left / right balance adjustment amount.

  In the above description, the straight line distance between BB ′ is approximated as the length of the circular arc. However, as shown in FIG. 4B, the auxiliary line passing through the straight line connecting point A and B and the point A is parallel to the Y axis. Assuming that the angle formed by the line is α1, and the angle formed by the straight line connecting A and B ′ and the auxiliary line is α2, tan α1 = (Xa−Xb1) / (Yb1−Ya), tan α2 = (Xb2−Xa) / Since it is (Yb2-Ya), the rotation angle can be calculated more accurately by calculating α1 and α2. Then, the rotation angle obtained by adding α1 and α2 is associated with the rotation angle of the rotary resistor (similarly, the added rotation angle and the rotation angle of the rotary resistor are not necessarily matched. ), Set the volume adjustment amount and left / right balance adjustment amount.

  In this way, the volume adjustment amount and the left / right balance adjustment amount are not simply set according to the movement amount on the track pad 6, but the fulcrum is centered based on the fulcrum position information and the start point and end point position information. Rotating the rotary resistor to calculate the rotation angle and to associate the rotation angle with the rotation angle of the rotary resistor and set the volume adjustment amount and left / right balance adjustment amount With the same feeling, the volume and the left / right balance can be adjusted on the track pad 6. Also, in this method, if the distance between two fingers is narrowed for the same amount of movement, the amount of change in the rotation angle increases, and if the distance is widened, the amount of change in the rotation angle decreases. Compared with the control method, the volume and the left / right balance can be adjusted more quickly and accurately.

  In the above description, two fingers are used and the rotation angle around the position of one finger is calculated. For example, as shown in FIG. Here, a fulcrum is set in advance at the approximate center of the lower side of the track pad 6, and based on the position information of the fulcrum and the position information of the start point and end point when one finger is moved, You may calculate the rotation angle centering on a fulcrum.

  By using the above method, the volume and the left / right balance can be adjusted in the same way as when the rotary resistor is turned. If it is known whether the balance is adjusted, the adjustment work becomes easy. Therefore, the acoustic device 2 displays information whose form changes according to the rotation angle on the display unit 12 so that the volume and the adjustment amount of the left / right balance can be visually recognized according to the received command signal. Specifically, for example, as shown in FIG. 5A, the volume adjustment amount is expressed numerically, or a circular or semi-circular display area in which fan-shaped liquid crystal blocks are connected is provided, and according to the volume adjustment amount. By changing the brightness and display color of the fan block, or by placing a light source such as an LED on the circumference and turning on the light source according to the volume adjustment amount, as shown in FIG. Expresses the amount of volume adjustment. Thus, the user can easily adjust the desired volume and balance while viewing the display unit 12.

  Next, a remote controller, a remote control system, and a remote control method according to a second embodiment of the present invention will be described with reference to FIGS. FIG. 6 is a diagram showing the main means and signal flow of the remote controller and the audio equipment, and FIG. 7 is a diagram schematically showing the movement of the finger on the track pad. FIG. 8 is a diagram showing the coordinates of the finger of the track pad, and FIG. 9 is a diagram showing an example of the volume and left / right balance of the audio equipment.

  In the first embodiment described above, the rotation angle is calculated based on the movement of the finger on the track pad 6, and one operation is controlled based on the rotation angle (for example, volume adjustment or left / right balance adjustment). However, in the present embodiment, a case where two or more operations are controlled simultaneously using the track pad 6 (for example, volume adjustment and left / right balance adjustment) will be described.

  In this embodiment, as shown in FIG. 6, the remote controller 3 includes an arithmetic processing unit 9 including an arithmetic circuit and a command signal generation circuit, and a remote control signal generator including a modulator and an amplifier. The audio equipment 2 is provided with a remote control signal receiving unit 11 including a receiver, a demodulator, and the like, a display unit 12 for displaying various information, and an acoustic control including an amplifier. The unit 14, a sound source 13 that separately generates left and right sound signals, and two speakers (a left speaker 15 a and a right speaker 15 b) that separately output left and right sounds are provided.

  Here, conventionally, the movement amount is calculated from the position information on the track pad 6 and only a command signal for controlling one operation is generated from the movement amount. However, the position information of the track pad 6 is X / Including the two-dimensional information on the Y axis, this embodiment can be operated in two ways by controlling the information in the X-axis direction and the information in the Y-axis direction. I am letting.

  That is, in this embodiment, the position information (X-axis and Y-axis coordinates) detected by the track pad 6 is sent to the arithmetic processing unit 9, and the position information is decomposed into components of each axis by the arithmetic circuit, and the command signal Two command signals are generated on the basis of each component in the generation circuit. Then, the two generated command signals are sent to the remote control signal generator 10, modulated, amplified, and transmitted as infrared rays, ultrasonic waves, or weak radio waves. On the other hand, the remote control signal receiving unit 11 of the acoustic device 2 receives and demodulates the transmitted remote control signal, and then transmits it to the display unit 12 and the acoustic control unit 14, and the display unit 12 performs display based on the command signal, The sound control unit 14 amplifies the left and right separate signals transmitted from the sound source 13 with the volume and balance specified by the command signal, and sounds the left and right speakers 15a and 15b.

  For example, first, the function selection button 5 of the remote controller 3 is pressed to press a previously provided volume + balance adjustment button (the button on the lower left of the function selection button 5 in FIG. 1) to perform two operations. Select the mode to control simultaneously. Next, as shown in FIG. 7, the finger is moved up, down, left and right on the track pad 6. Here, the position information of the track pad 6 and the control information of the audio device 2 are associated in advance. For example, the volume is controlled in the first control direction (here, the Y-axis direction), and the second direction ( If it is defined that the balance is controlled in the X-axis direction here, it is possible to simultaneously instruct both volume adjustment and left-right balance adjustment from the position of the finger.

  Specifically, as shown in FIGS. 8 and 9, when a finger is placed on the point A on the track pad 6, the volume level is set to a predetermined value (here, “6”), and the point A Is approximately the center in the X-axis direction, so the balance is set to be approximately equal on the left and right. When a finger is placed on point B on the track pad 6, the Y-axis coordinates are the same as point A, so the volume is set to a predetermined value (here, “6”), and point B is X Since it is from the right in the axial direction, the balance is set so that the right output becomes larger. When the finger is placed at point C on the track pad 6, the Y-axis coordinate is smaller than point A, so the volume is set to a predetermined value (here, “5”) smaller than point A. Since it is from the left of the X axis, the balance is set so that the output on the left increases.

  As described above, the position information of the finger on the track pad 6 is decomposed into the components of each axis, and the command signal is generated based on each component. Two operations can be controlled simultaneously.

  In the above-described embodiment, the volume control and the left / right balance control are described as examples of the two controls. However, the type of control is not particularly limited, and may be two or more different controls. For example, brightness (brightness) control, image color density (contrast), and gamma value control may be used. In the above description, the first control is performed based on the X-axis coordinates, and the second control is performed based on the Y-axis coordinates. However, the two controls may be performed based on position information in different directions. A plurality of operations may be controlled based on position information in the respective axial directions with two lines connecting the diagonals of the track pad 6 as axes. In the above description, the configuration is such that two operations are controlled based on two axes. However, a configuration in which three or more operations are controlled based on three or more axes may be employed.

  In the above embodiment, two controls are performed according to the position of the finger on the track pad 6. However, two controls may be performed based on the movement of the finger on the track pad 6. In that case, the displacement of the position may be decomposed into an X coordinate and a Y coordinate, and each operation may be controlled according to the amount of change in each coordinate.

  Next, a remote controller, a remote control system, and a remote control method according to a third embodiment of the present invention will be described with reference to FIGS. 10 and 11 are diagrams illustrating examples of screens displayed on the display unit of the audio equipment.

  In the first and second embodiments described above, control is performed based on the positional information of one or two fingers. However, in this embodiment, a third finger or a plurality of fingers are further added. Will be described.

  Specifically, in the state where two fingers are placed as shown in FIG. 3 (a), or in the state where one finger is placed as shown in FIG. When the (for example, the middle finger) is placed in a predetermined area (for example, the right end) on the track pad 6, the arithmetic processing unit 9 recognizes that the fine adjustment mode 1 has been entered. Then, when displaying the information whose form changes according to the rotation angle on the display unit 12, the display is performed so that it can be clearly seen that the fine adjustment mode has been entered. For example, as shown in FIG. 10, information for recognizing the fine adjustment state is displayed at a predetermined position on the display unit 12 (for example, a position corresponding to the maximum value of the current level), and the fine level change is performed. To understand.

  Further, when the fourth finger (for example, ring finger) is placed on a predetermined area (for example, the right end) on the track pad 6, the arithmetic processing unit 9 recognizes that the fine adjustment mode 2 has been entered. Then, when displaying information whose form changes according to the rotation angle on the display unit 12, the display is performed so that it is clearly understood that the fine adjustment mode 2 has been entered. For example, as shown in FIG. 11, information for recognizing the fine adjustment state is displayed in a plurality of stages (for example, two stages) so that the change in a finer level can be understood.

  As the fine adjustment method, for example, a method of changing the amplification factor in the arithmetic processing unit 9 based on the position information of the third and fourth fingers from the track pad 6 can be considered. That is, the magnitude of the command signal is Vorder, the magnitude of the signal corresponding to the rotation angle is Vangle, and the constant K is changed when the relationship of Vorder = K × Vangle holds. For example, according to the information of the third and fourth fingers from the track pad 6, the constant K which is the sensitivity is reduced to 1/2, 1/4, etc. in the fine adjustment modes 1 and 2 as compared with the normal case. If it is changed, the change in the magnitude of the command signal with respect to the movement of the finger is reduced, so that the value to be adjusted can be finely adjusted.

  In each of the above embodiments, the controller 3 that controls the acoustic device 2 has been described. However, the present invention is not limited to the above embodiment, and may be applied to, for example, a controller that controls other types of devices. It can also be applied to an audio device provided with a track pad 6.

  The present invention is not limited to a controller of an audio device, and can be applied to a controller that controls an arbitrary device, a device that includes a track pad, and the like.
