  The remote operation device 5 is for operating a graphical user interface (hereinafter referred to as GUI) displayed on the screen 4, and communicates with the computer 2 as display control means for controlling display of the GUI by wireless communication or wired communication. Communication (in this embodiment, wireless communication) is performed, and a user operation is transmitted. The remote operation device 5 has a simple external configuration in which one operation key 8 for distinguishing various operations described later is arranged near the front end portion 7A of the cylindrical case body 6, and the rear end portion is set by the user. The vicinity of 7B is gripped and operated.

The operation modes of the remote operation device 5 are classified into an overall rotation operation, a uniaxial rotation operation, a left / right swing operation, and a vertical swing operation based on the movement of the remote operation device 5 at the time of operation.
As shown in FIG. 2A, the entire rotation operation is performed by turning the tip of the arm from the arm holding the remote operation device 5 by the user and setting the starting point of the remote operation device 5 as the rotation center X. 5 is an operation of rotating to draw a circle (including an ellipse).
As shown in FIG. 2 (B), the uniaxial rotation operation is performed by using a long axis K that connects the distal end portion 7A and the rear end portion 7B of the remote operation device 5 by twisting the wrist holding the remote operation device 5 by the user. In this operation, the remote operation device 5 is rotated around one axis, and the rotation center X at this time is the long axis K.

In this operation, the tip 7A of the remote operation device 5 is rotated so as to draw a circular arc on the left and right with the vicinity of 7B as the rotation center X.
As shown in FIG. 2D, the up / down swing operation is performed by setting the rotation center X around the rear end 7B of the remote operation device 5 by swinging the wrist holding the remote operation device 5 up and down. This is an operation of rotating the tip portion 7A of the device 5 so as to draw an arc vertically.
Then, the GUI operation is performed by performing any of the above operations. A specific example of the GUI will be described in detail later.

FIG. 3 is a block diagram showing a functional configuration of the remote operation device 5. The remote operation device 5 includes a CPU 10 as a control means for centrally controlling each unit, a communication I / F 11 that is a wireless communication interface with the computer 2, the operation key 8, and a motion detection unit 12. Yes.
The motion detection unit 12 detects the motion of the remote operation device 5, and includes an X-axis gyro sensor 13A, a Y-axis gyro sensor 13B, a Z-axis gyro sensor 13C, and the X-axis, Y-axis, and Z-axis gyros. And an A / D converter 15 provided for each of the sensors 13A to 13C.
In the following description, as shown in FIG. 4, the direction in which the operation key 8 is exposed upward is the upward direction, the axis along the upward direction is the Y axis, the long axis K is the Z axis, and these The description will be made assuming that the axis orthogonal to the Y axis and the Z axis is the X axis.
The X-axis gyro sensor 13A detects the pitching of the case body 6 using the left-right direction (X-axis direction) of the case body 6 as a detection axis, and outputs a detection signal to the CPU 10 via the A / D converter 15. The Y-axis gyro sensor 13 </ b> B detects yawing of the case body 6 using the vertical direction (Y-axis direction) of the case body 6 as a detection axis, and outputs a detection signal to the CPU 10 via the A / D converter 15. The Z-axis gyro sensor 13 </ b> C detects rolling of the case body 6 using the long axis K (Z-axis) of the case body 6 as a detection axis, and outputs a detection signal to the CPU 10 via the A / D converter 15.

The CPU 10 sequentially generates motion signals indicating the motion of the remote operation device 5 based on detection signals from the X-axis, Y-axis, and Z-axis gyro sensors 13A to 13C. Specifically, in this embodiment, when the CPU 10 detects pitching of the case body 6 based on the detection signal of the X-axis gyro sensor 13A, the case body 6 moves upward (Y-axis positive direction). When it is moving, it outputs a motion signal (hereinafter referred to as “↑”) indicating upward movement, and when it is moving downward (Y-axis negative direction), it indicates a downward movement signal (hereinafter “↓”). Output).
Further, when the CPU 10 detects yawing of the case body 6 based on the detection signal of the Y-axis gyro sensor 13B, when the case body 6 is moving in the right direction (X-axis positive direction), the CPU 10 When a movement signal indicating movement (hereinafter referred to as “→”) is output and moving in the left direction (X-axis negative direction), a movement signal indicating movement in the left direction (hereinafter referred to as “←”). ) Is output.

Furthermore, when the CPU 10 detects rolling of the case body 6 based on the detection signal of the Z-axis gyro sensor 13C, the case body 6 is rolling clockwise around the long axis K (Z axis). A motion signal indicating the right rolling (hereinafter referred to as “RR”) is output, and when rolling counterclockwise, a motion signal indicating the left rolling (hereinafter referred to as “RL”) is output.
These motion signals are sequentially transmitted to the computer 2 via the communication I / F 11. Further, the CPU 10 transmits a pressing signal to the computer 2 via the communication I / F 11 while the operation key 8 is pressed.
In the computer 2, the operations performed on the remote operation device 5 based on the presence or absence of the series of motion signals and pressing signals are the total rotation operation, the uniaxial rotation operation, the left and right swing operation, and the up and down swing operation described above. Which of the following is true.

FIG. 5 is a flowchart of the operation type determination process executed by the computer 2. When the input of the motion signal is started, the computer 2 first, as shown in FIG. 5, first, the whole rotation operation and the uniaxial rotation operation without the operation key 8 operation, the movement operation and the rotation operation, and the operation key 8 In order to identify each of the left and right swing operations and the up and down swing operations involving the above operations, it is determined whether or not a pressing signal is input (step Sa1).
When the pressing signal is not input (step Sa1: NO), that is, when the operation is a total rotation operation or a uniaxial rotation operation, the computer 2 determines whether the operation is the total rotation operation or the uniaxial rotation operation. The following processing is performed to determine

That is, the computer 2 determines whether or not the motion signal “RR” or “RL” indicating the right rolling or the left rolling that is output in accordance with the uniaxial rotation operation is detected (step Sa2). (Step Sa2: YES), it is determined that the current operation is a uniaxial rotation operation (Step Sa3). On the other hand, if the motion signal “RR” or “RL” is not detected (step Sa2: NO), the current operation may indicate the entire rotation operation, so the following processing is executed.
That is, when the left or right motion signal “←” or “→” is input, the computer 2 holds the motion signal as an initial value (step Sa4). Next, the computer 2 determines whether or not the motion signal input following the initial motion signal is an upward or downward motion signal “↑” or “↓” (step Sa5). If the motion signal is “↑” or “↓” in the downward direction (step Sa5: YES), the computer 2 determines that the current operation is a left or right rotation operation (step Sa6). If the result of the determination in step Sa5 is not the upward or downward motion signal “↑” or “↓” (step Sa5: NO), the operation is not specified, so the computer 2 first determines the operation type. In order to start over, the initial value is cleared (step Sa7), and the processing procedure is returned to step Sa1.

On the other hand, as a result of the determination at step Sa1, if the operation key 8 is pressed (step Sa1: YES), that is, if it is either the up / down swing operation or the left / right swing operation, the computer 2 moves up or down. It is determined whether or not the direction motion signal “↑” or “↓” is input (step Sa8). When the motion signal “↑” or “↓” is input (step Sa8: YES), the computer 2 determines that the current operation is a vertical swing operation (step Sa9), and the motion signal “ When “↑” or “↓” is not input (step Sa8: NO), it is determined whether a left or right motion signal “←” or “→” is input (step Sa10). If the motion signal “←” or “→” is input (step Sa10: YES), it is determined that the current operation is a left-right swing operation (step Sa11). If the motion signal “←” or “→” is not input (step Sa10: NO), the operation is not specified, so the computer 2 clears the initial value in order to start the operation type determination from the beginning ( Step Sa12), the processing procedure is returned to Step Sa1.
In the above operation type determination process, in order to more accurately identify the entire rotation operation, a sequence of motion signals that are sequentially input are added to the motion signal array pattern (“←”, “↑”, “→”). ”,“ ↓ ”or“ ← ”,“ ↓ ”,“ → ”,“ ↑ ”).

As described above, after the computer 2 determines the type of operation performed on the remote operation device 5 by the user, the computer 2 executes processing corresponding to the operation type.
More specifically, in the present embodiment, as shown in FIG. 6, the user operates the remote operation device 5 to select a desired item from a plurality of selection items 32A to 32I (indicated by reference numeral “32” unless otherwise distinguished). An item selection screen 30 for selecting the selection item 32 is displayed on the screen 4 as a GUI. In this item selection screen 30, a plurality of (eight in the illustrated example) selection items 32A to 32I are annular around the center O of the screen, more specifically, along a circumference 31 centered on the center O. In the center O, a home mark 33 which is a mark indicating the home position (initial position) is arranged. The circumference 31 does not have to be a perfect circle, and may be an ellipse or other curved line.

In the initial state of the item selection screen 30 (when the remote operation device 5 is not operated), the home mark 33 is surrounded by a thick frame 34 and is in a selected state. When the user grips the remote operation device 5 and performs the overall rotation operation, each selection item 32 is surrounded by a thick frame 34 clockwise or counterclockwise according to the rotation direction at the time of the overall rotation operation. Are selected in order. Then, when the desired selection item 32 is in the selected state, the user performs an up / down swing operation (see FIG. 2D), and the operation is determined by the computer 2 by the operation type determination process and selected. The selection of the selection item 32 in the state is determined.
Thus, since the arrangement mode of the selection item 32 and the operation mode of the remote operation device 5 match, the user can intuitively operate the remote operation device 5 to select each selection item 32. .
The item selection on the item selection screen 30 may be configured to be performed by a uniaxial rotation operation in addition to (or instead of) the entire rotation operation.

  Here, when the entire rotation operation is performed on the remote operation device 5, the computer 2 starts the process of sequentially selecting each selection item 32, and the selection item is selected while the entire rotation operation is continuously performed. 32 selections are continuously switched. At this time, the selection switching speed of the selection item 32 is constant in the initial state regardless of the rotation speed during the entire rotation operation. However, for example, when a large number of selection items 32 are displayed on the item selection screen 30, the user needs to continue to rotate the remote operation device 5 a number of times until the desired selection item 32 is selected. There is. Therefore, in the present embodiment, in order to reduce the time required for selection and the total number of rotation operations, when the same type of operation is continuously performed a predetermined number of times, according to the rotation speed at that time. The selection switching speed is increased.

  FIG. 7 is a flowchart of a speed variable process for changing the selection switching speed. After the computer 2 determines the operation type by the operation type determination process shown in FIG. 5, whether the same type of operation has been repeatedly input based on the motion signal pattern sequentially input as shown in FIG. 7. Whether or not is determined based on the motion signal (step Sb1). For example, when the entire rotation operation of the right rotation is performed, the computer 2 is a motion signal pattern during the entire rotation operation of the right rotation [“←”, “↑”, “→”, “↓”]. It is determined whether or not is continuously input. If the same type of operation is not repeatedly input (step Sb1: NO), the process is terminated because the speed does not need to be switched, and if it is repeatedly input (step Sb1: YES). ), It is determined whether or not the number of repetitions is a predetermined number or more (step Sb2).

  When the number of repetitions is less than the predetermined number (step Sb2: NO), the computer 2 returns the processing procedure to step Sb1, and determines whether or not the same type of operation is continuously performed. If the number of repetitions is equal to or greater than the predetermined number (step Sb2: YES), the computer 2 determines whether or not the user is moving the remote operation device 5 relatively quickly in order to speed up the selection switching. It is determined whether or not the time until the end of the operation is equal to or shorter than a predetermined time (step Sb3). If one operation time exceeds the predetermined time (step Sb3: NO), the computer 2 returns the processing procedure to step Sb1, and if one operation time is equal to or less than the predetermined time (step (Sb3: YES), the selection switching speed of the selection item 32 is increased (step Sb4).

Now, as described above, the selection operation of the selection item 32 is performed by rotating the remote operation device 5 as a whole on the item selection screen 30, but in this embodiment, the remote operation device 5 is rotated as a whole. By operating, GUI operations other than the item selection screen 30 can be operated.
Specifically, the selection items 32A to 32I displayed on the item selection screen 30 function as selection keys for displaying various screens. For example, according to the selection items 32A to 32I selected and determined, for example, A GUI such as a moving image display screen 40, a still image display screen 41, and a document display screen 42 is configured to be displayed on the screen 4.
As shown in FIG. 8, the moving image display screen 40 is a GUI for displaying a moving image as one aspect of the display object on the screen 4. By rotating the entire remote operation device 5 on the moving image display screen 40, Fast forward (entire rotation operation of right rotation) and rewind (overall rotation operation of left rotation) are performed.
As shown in FIG. 9, the still image display screen 41 is a GUI that displays a still image such as a photograph as one aspect of the display object on the screen 4. In the still image display screen 41, the remote operation device 5 is uniaxial. By rotating, the still image is rotated 90 degrees to the right (right rolling uniaxial rotation operation) and left 90 degrees (left rolling uniaxial rotation operation).

As shown in FIG. 10, the document display screen 42 is a GUI that displays document data consisting of a plurality of pages, which is an aspect of the display object, on the screen 4. In the document display screen 42, the remote operation device 5 is displayed. By performing a left / right swing operation, page feed (a swing operation in the right direction) and page return (a swing operation in the left direction) are performed.
Also in the GUI such as the moving image display screen 40, the still image display screen 41, and the document display screen 42, the fast forward / rewind speed of the moving image, the rotational speed of the figure, and the figure depending on the number of operations of the remote operation device 5. The number of page feed / return pages and the like are changed in the same manner as in the speed variable process.

As described above, according to the present embodiment, each of the plurality of selection items 32 is arranged and displayed along the circumference in the item selection screen 30 and is selected by the entire rotation operation of the remote operation device 5. Since each of the items 32 is displayed in order, the display mode of the selection item 32 matches the operation mode for selecting the desired selection item 32, and the user intuitively operates the remote operation device 5. Can be selected. In particular, since the selection operation is enabled by an operation that can be easily performed by many humans, such as rotating the remote operation device 5, the selection operation becomes easy.
Further, according to the present embodiment, since the selection operation can be executed without operating any operation element such as an operation button, the operability is improved.

Further, according to the present embodiment, the configuration in which the selection order of the selection items 32 arranged along the circumference in the item selection screen 30 is combined with the rotation direction during the entire rotation operation of the remote operation device 5 is provided. Therefore, the selection operation of the selection item 32 can be performed more intuitively.
In addition, according to the present embodiment, the selection item 32 to be selected is switched at a speed that is increased according to the speed at the time of the entire rotation operation of the remote operation device 5. The user can quickly select the desired selection item 32 by accelerating the rotation of the remote operation device 5.

  In particular, in the present embodiment, when the remote operation device 5 is continuously rotated for a predetermined number of times or more, the selection item 32 to be selected is quickly switched, so that it is displayed in the item selection screen 30. If the desired selection item 32 is not selected even if a predetermined number of entire rotation operations are performed because the number of selection items 32 is large, the selection item 32 is automatically switched, so that the selection item 32 Even if the number of 32 increases, a desired selection item 32 can be quickly selected.

In the present embodiment, GUI operations other than the item selection screen 30, such as the moving image display screen 40, the still image display screen 41, and the document display screen 42, are also performed by moving the remote operation device 5. The GUI operation can be easily performed without requiring a complicated operator operation.
As described above, the selection operation of the selection item 32 on the item selection screen 30 may be performed by a uniaxial rotation operation instead of the entire rotation operation.

The above-described embodiments merely show one aspect of the present invention, and can be arbitrarily modified and applied within the scope of the present invention.
For example, in the above embodiment, the computer 2 determines the operation type for the remote operation device 5. However, the remote operation device 5 determines the operation type and transmits the determination result to the computer 2. good. Further, the variable speed process shown in FIG. 7 may be performed by the remote operation device 5 to give a variable instruction of the selected speed to the computer 2.

  Further, for example, the remote operation device 5 may be provided with a malfunction prevention key, and the remote operation device 5 may transmit a motion signal to the computer 2 only while the malfunction prevention key is pressed. According to this configuration, it is possible to prevent a situation in which an operation of a user who does not intend to perform an operation is judged as an operation by the computer 2 and malfunctions.

Further, for example, in the above-described embodiment, the operation mode (type) of the remote operation device 5 is exemplified only for the operation of rotating around the rotation center X, but is not limited thereto. For example, as shown in FIG. 11, as a GUI, a line drawing is drawn on the drawing screen 43 which is a GUI for drawing a line drawing on the screen according to the movement locus when the remote operation device 5 is moved. Operation is also possible.
More specifically, on the drawing screen 43, a canvas 430 on which a line drawing is drawn and a pen object 431 are displayed, and a line 432 is drawn on the canvas 430 by the movement locus of the pen object 431. When the movement signals “↑”, “↓”, “←”, “→”, “RR”, and “RL” when the remote operation device 5 is freely moved are sequentially input on the drawing screen 43, the computer 2 moves accordingly. In response to the signal, the pen object 431 is moved on the canvas 430 by a predetermined distance, and a line 432 is drawn on the movement locus. A palette 433 formed by collecting icons indicating commands related to line drawing such as line erasure instruction, line 432 thickness designation, and color designation is displayed on the drawing screen 43, and the pen object 431 is operated by the remote operation device 5 to operate the palette. When the user moves to 433 and performs an up / down swing operation, the selection of the icon pointed to by the pen object 431 may be determined.

Moreover, although the case where this invention was applied to the projector system 1 was illustrated in the said embodiment, it is not restricted to this, It applies to the system which operates the selection item screen displayed on various display apparatuses, such as a television and a computer display. Is possible.
Furthermore, it is also possible to incorporate the function of the remote operation device 5 into an electronic device that is held and used by a user such as a mobile phone.
The operation device according to the present invention can be used as an input device for various information to a computer, for example, in addition to an operation device for operating a GUI. As an application example, for example, the remote operation device 5 described in the above embodiment is moved, and a predetermined movement pattern (for example, “↑”, “↓”, “←”, “↓”) is used as a password to the computer 2. There is an application in which the computer 2 locks various operations until it is registered in advance and the movement pattern is input from the remote operation device 5 to the computer 2.
