Description

  The present invention relates to a device control device and a device control processing program, and more particularly to a device control device having a multi-control function for controlling a plurality of types of devices and a device control processing program.

  Remote control devices that remotely control electronic devices such as television receivers and air conditioners are widely used. Conventionally, the user controls each electronic device by operating a dedicated remote controller. However, there are many electronic devices in the home as in the present age, in addition to television receivers and air conditioners, CD devices that play music songs recorded on CDs, and amplify audio signals and output them to speakers. It is necessary to control amplifier devices and other electronic devices with a remote control device dedicated to each electronic device. However, it is very complicated to operate many dedicated remote control devices. In addition, if a remote control device of a different electronic device is operated by mistake, an accident may occur. In addition, manufacturers of a plurality of types of electronic devices need to manufacture a dedicated remote control device for each electronic device, which causes an increase in cost as a whole. In recent years, therefore, proposals have been made for controlling a plurality of types of electronic devices using a common remote controller.

For example, according to a proposed remote control device, a display for controlling a television receiver (FIG. 3) and a display for controlling a video recorder (FIG. 4) are made possible by the same remote control device. It is configured to control two different devices. (See Patent Document 1)
Further, according to a proposed remote control device, an input unit for remotely operating a plurality of operation target devices and a control signal for controlling each operation target device in a direction in which the remote control device is directed are recorded in association with each other. A signal recording unit, a direction sensing unit that senses the direction in which the remote control device is directed, and a control unit that selects a control signal of a corresponding operation target device from the signal recording unit based on the sensed direction and an input from the input unit The operation target device can be remotely operated based on the selected control signal. For example, the direction sensing unit senses that the remote control device is directed to “east”, and selects the control signal of the operation target device stored in association with the “east” direction. (See Patent Document 2)

  According to the apparatus of the present invention, it is possible to remotely control different types of controlled devices by an extremely simple operation without providing special hardware.

Hereinafter, the first to third embodiments of the device control apparatus of the present invention will be described with reference to the drawings by taking a remote control device as an example.
FIG. 1 is a plan view of a remote control device 1 according to the first embodiment. The remote control device 1 is provided with a display unit 2 that displays various information for the user. The screen of the display unit 2 is provided with a touch panel 3 including a transparent electrode that senses the contact of a rod-like drawing unit (hereinafter simply referred to as “pen”) such as a stylus pen (not shown). The touch panel 3 can sense the touch position of the pen by two-dimensional coordinates (x, y). A star mark (★) 4 is formed at a predetermined position of the remote control device 1 by engraving or printing. On the four edge portions of the display unit 2, “TV” 5, “Air conditioner” 6, icons representing devices to be controlled, that is, TV receiving devices that are controlled devices, air conditioner devices, CD devices, and amplifier devices, “Amplifier” 7 and “CD” 8 are displayed. These icons can be set according to the operation of the touch panel 3 by the user. Further, these icons need not always be displayed, and may be displayed at the time of setting and in response to a user display command.

  The user draws and inputs a control command for the controlled device on the touch panel 3 in a state in which the displayed icon is normally viewed, that is, in a direction in which the position of the star mark 4 is on the other side. The state of FIG. 1 represents a drawing input when the channel of the television receiving device is designated as “6”. When controlling the CD device, the remote control device 1 is rotated 90 ° counterclockwise, and a control command is drawn and input at a position where the star mark 4 is on the left side. When controlling the amplifier device, the remote controller 1 is rotated 180 ° counterclockwise or clockwise, and a control command is drawn and input at a position where the star mark 4 is on the near side. When controlling the air conditioner device, the remote controller 1 is rotated 270 ° counterclockwise or 90 ° clockwise, and a control command is drawn and input at a position where the star mark 4 is on the right side.

  FIG. 2 is a block diagram showing an internal configuration of the remote control device 1 of FIG. The CPU 11 is composed of a one-chip IC having a program ROM (not shown) therein, and is the display unit 2 and the touch panel 3, the work RAM 13, and the nonvolatile memory shown in FIG. The remote controller 1 is connected to the flash ROM 14 and the signal transmitter 15, and exchanges commands and data with these units to control the remote controller 1. The work RAM 13 temporarily stores data processed by the CPU 11. The flash ROM 14 is configured with numbers, characters, symbols, and graphics set in advance as icon settings for the controlled device, a signal format of a control signal for the controlled device, and a drawing input for a control command for the controlled device. And vector direction patterns corresponding to these combinations are stored in a dictionary table to be described later. The signal transmission unit 15 is connected to the wireless transmission unit 16 and performs modulation processing of a signal transmitted from the wireless transmission unit 16 toward the controlled device in accordance with a control signal from the CPU 11.

  FIG. 3 is a diagram showing the orientation of the remote control device 1 and the drawing of control commands for a plurality of types of controlled devices. FIG. 3A illustrates a state in which the number of the control command “6” is drawn without rotating the remote control device 1 (0 °). FIG. 3B shows a state in which the number of the control command “6” is drawn by rotating the remote control device 1 by 90 ° counterclockwise. FIG. 3 (2) shows a state in which the number of the control command “6” is drawn by rotating the remote control device 1 by 180 ° counterclockwise or clockwise. FIG. 3 (4) shows a state in which the number of the control command “6” is drawn by rotating the remote control device 1 270 ° counterclockwise or 90 ° clockwise. The user makes a control command “6” based on the position of the star mark, and the CPU 11 analyzes the contents of the control command and its controlled device according to the vector direction of the drawing input according to the two-dimensional coordinates of the touch panel 3.

FIG. 4A is a diagram illustrating a reference for analyzing the vector direction of a drawing input. The drawing vector direction is represented by “A” to “H” in accordance with the direction from the position “O”. Now, the coordinates of “O” are (xj, yk: j, k = 1 to n), the absolute value of the movement amount of the x coordinate by drawing is p, and the absolute value of the movement amount of the y coordinate is q. In this case, the vector directions “A” to “H” are expressed as follows.
“A”: “(xj, yk) → (xj + p, yk)”
“B”: “(xj, yk) → (xj + p, yk + q)”
“C”: “(xj, yk) → (xj, yk + q)”
“D”: “(xj, yk) → (xj−p, yk + q)”
“E”: “(xj, yk) → (xj−p, yk)”
“F”: “(xj, yk) → (xj−p, yk−q)”
“G”: “(xj, yk) → (xj, yk−q)”
“H”: “(xj, yk) → (xj + p, yk−q)”

  FIG. 4B is a diagram illustrating the analysis of the vector direction when the control command “6” is drawn. According to the drawing of “6”, as indicated by arrows, vectors of “D”, “F”, “G”, “G”, “H”, “B”, “C”, “D”, “F” Become a direction. The CPU 11 discriminates the number “6” and the direction “6” from the vector direction pattern and the dictionary table stored in the flash ROM 14. In the case of FIG. 4B, it is determined that the input is a drawing input when the channel of the television receiving device is designated as “6”.

  In the case of FIG. 4 (2), “6”, which is a so-called “one-stroke” number, is drawn, but it cannot be drawn with one stroke like “4”, “5”, “7”. There are also numbers. For this reason, the CPU 11 is not only in the vector direction when the pen is drawn in contact with the touch panel 3 (pen down state), but also after the pen leaves the touch panel 3 and drawing is temporarily suspended, the pen again touches the touch panel 3. It is necessary to analyze the vector direction from the interruption to the restart in the state where the drawing is resumed by touching (pen-up state).

FIG. 5A is a diagram illustrating a reference for analyzing the vector direction of the pen-up state from interruption to resumption. The drawing position is sampled in the pen-down state, but not sampled in the pen-up state, so the drawing vector direction is the position where the pen contacts the touch panel 3 again from the position “0” where the pen is away from the touch panel 3. It is represented by “1” to “8” according to the direction of Now, the coordinates of “0” are (xj, yk: j, k = 1 to n), the absolute value of the movement amount of the x coordinate from the interruption to the restart is r, and the absolute value of the movement amount of the y coordinate is s. To do. In this case, the vector directions “1” to “8” are expressed as follows.
“1”: “(xj, yk) → (xj + r, yk)”
“2”: “(xj, yk) → (xj + r, yk + s)”
“3”: “(xj, yk) → (xj, yk + s)”
“4”: “(xj, yk) → (xj−r, yk + s)”
“5”: “(xj, yk) → (xj−r, yk)”
“6”: “(xj, yk) → (xj−r, yk−s)”
“7”: “(xj, yk) → (xj, yk−s)”
“8”: “(xj, yk) → (xj + r, yk−s)”

  FIG. 5B is a diagram illustrating an analysis of the vector direction of the pen-down state when the control command “5” is drawn. As shown in the figure, following the drawing of “5”, as shown by solid arrows, “G”, “B”, “H”, “G”, “F”, “D” are drawn, and then the pen Leaves the touch panel 3. Then, as indicated by the dotted arrow, the pen moves almost directly to the position where drawing is resumed. Therefore, the vector direction from the interruption to the restart is “3”. After drawing is resumed, the vector directions of “A” and “A” are obtained as indicated by solid arrows. The CPU 11 discriminates the number “5” and the direction “5” from the vector direction pattern and the pattern stored in the flash ROM 14. In the case of FIG. 5B, it is determined that the input is a drawing input when the channel of the television receiving device is designated as “5”.

  FIG. 6 is a diagram illustrating an example of an exemplary vector direction pattern by drawing and inputting numbers “0” to “9”. Although this pattern is stored in the dictionary table of the flash ROM 14, not only FIG. 6 but also various variations are stored. This is because the user does not always draw numbers in the shape of FIG.

FIG. 7 is a diagram showing an analysis of the vector direction when the control command “7” is drawn so as to be different from the shape shown in FIG. In FIG. 7A, the pen leaves the touch panel 3 after drawing in the vector direction “G”. Then, as indicated by the dotted arrow, the pen moves almost directly to the position where drawing is resumed. Therefore, the vector direction from the interruption to the restart is “3”. After drawing is resumed, “A”, “A”, “F”, “F”, and “F” are drawn as indicated by solid arrows. On the other hand, in FIG. 7B, the vector direction “G” is not drawn, and “A”, “A”, “F”, “F”, “F” are drawn with a single stroke as indicated by solid arrows. "Is drawn. Therefore, the pattern of the control command “7” stored in the flash ROM 14 is expressed as follows including the pattern of the example shown in FIG.
Pattern of FIG. 6: “F”, “2”, “A”, “A”, “F”, “F”, “G”
Pattern of FIG. 7 (1): “G”, “3”, “A”, “A”, “F”, “F”, “F”
Pattern of FIG. 7 (2): “A”, “A”, “F”, “F”, “F”

  FIG. 8 shows “0 °” without rotating the remote control device 1, “90 °”, “180 °” counterclockwise, and “270 °” counterclockwise (or “90 ° clockwise”). It is a figure which shows the case where the number "6" is drawn in the rotated state. As shown in FIG. 8, the user draws the same number “6” simply by rotating the remote control device 1, but the CPU 11 controls the two-dimensional coordinates of the touch panel 3 and the control commands stored in the flash ROM 14. Based on the pattern “6”, the contents of the control command and the controlled device are determined.

  That is, as shown in FIGS. 8A to 8D, when the remote control device 1 is “0 °”, “D”, “F”, “G”, “G”, “H” , “B”, “C”, “D”, “F”, and when the remote control device 1 is “90 °”, “F”, “H”, “A”, “A” , “B”, “D”, “E”, “F”, “H”, and when the remote control device 1 is “180 °”, “H”, “B”, “C” , “C”, “D”, “F”, “G”, “H”, “B”, and when the remote control device 1 is “270 °”, “B”, “D” , “E”, “E”, “F”, “H”, “A”, “B”, “D”. In this way, it is possible to detect the drawing input direction depending on which pattern is matched, and to select a control target.

  FIG. 9 is a dictionary table for recognizing an exemplary vector direction by drawing and inputting numbers “0” to “9” shown in FIG. If the flash ROM 14 of FIG. 2 has a sufficient storage capacity, all of these may be stored in advance, but if the storage capacity is small, a dictionary table of “0 °” is stored as a basic dictionary. The remaining orientations may be temporarily stored after being converted from the basic dictionary each time the direction is recognized. This dictionary conversion is only a simple rule-based replacement, and does not become a big burden in the entire recognition process. Note that the dictionary table of FIG. 9 is merely an example. As described above, the drawing shape of the number “7” may be different depending on the user, and the drawing order may be different depending on the user. Therefore, various patterns of dictionary tables are stored in the flash ROM 14.

  Thus, in order to analyze patterns drawn from different directions, the program ROM of the CPU 11 stores an algorithm of HMM (Hidden Markov Model). HMM is one of probabilistic models and estimates unknown parameters from observable information on the assumption that the system is a Markov process with unknown parameters. Specifically, when the data series starts from the state Si, the probability aij of transition from the state Si to another state Sj is expressed as the initial state distribution π = {πi} by the state transition probability matrix A = {aij}. In other words, an observed symbol probability distribution B = {bj (k)} which is the probability of occurrence of the symbol k observed in the state Sj is obtained.

  FIG. 10 is a diagram illustrating an HMM probability model in a pen-down state in which the pen is in contact with the touch panel 3 and in a pen-up state in which the pen is separated from the touch panel 3 and is in contact again. FIG. 10 corresponds to an HMM that transitions only in the direction from left to right. The HMM in the pen-down state in FIG. 10 (1) has a model having self-transition probabilities a11, a22, a33 and probabilities a12, a23, a34 for transition to the next state for the drawn vectors of the states S1, S2, S3. It is represented by On the other hand, the HMM in the pen-up state in FIG. 10B is uniquely defined by the position where the pen is separated and the position where the pen is re-contacted regardless of the movement trajectory of the pen until the pen leaves the touch panel 3 and makes contact again. Therefore, the self-transition probability is represented by a model of “0”.

  FIG. 11 is a diagram specifically showing the cumulative output probability calculation performed from the initial state S0 with the probability “1.0” through the states S1 and S2 until reaching the final state S3. The probability calculation in this case uses a Viterbi algorithm that calculates a path (maximum likelihood path) having the highest possibility of transition (likelihood) when the model parameter is known. In FIG. 11, the numerical value indicated beside the solid line and dotted line arrows is the state transition probability. The output in the previous state multiplied by the state transition probability becomes the input in that state. Multiplying this value by the output probability specific to each state (upper numerical value in the square) gives the cumulative output probability (lower numerical value in the square), and this value is transferred to the next state. Let In FIG. 11, the route indicated by the solid line is the maximum likelihood route.

  According to the calculation of the cumulative output probability shown in FIG. 11, the pattern of the vector direction “6” in FIGS. 8 (1) to (4) is changed to “6 of 0 °” and “90 ° in the dictionary table shown in FIG. 6 ”,“ 180 ° 6 ”, and“ 270 ° 6 ”. Thus, by changing the drawing input direction with respect to the coordinate axes, for example, even when the same number “6” is drawn, four different control commands can be input. That is, in the example of FIG. 8, “0 ° 6” by the user is the channel 6 of the television receiver, “90 ° 6” is the selection of the sixth song of the CD, and “180 ° 6” is the amplifier. 6 of 270 ° is processed as 6 ° of the air conditioner temperature setting.

  FIG. 12 is a flowchart showing the operation of the device control process executed by the CPU 11 of FIG. Here, the direction of “0 °”, the direction of “90 °”, the direction of “180 °”, and the direction of “270 °” are respectively “direction 1”, “direction 2”, “direction 3”, “direction” 4 ”, and the controlled devices in the respective directions are device A, device B, device C, and device D.

When the start of handwriting is detected (step S1), it is determined whether or not it can be recognized in the direction 1 (step S2). If the direction 1 can be recognized, it is determined whether or not the command for the device A is appropriate (step S3). If the command is appropriate, the command for the device A is used as a control signal from the signal transmission unit 15. Transmit (step S4).
If it cannot be recognized in direction 1 in step S2, it is determined whether or not it can be recognized in direction 2 (step S5). If the direction 2 can be recognized, it is determined whether or not the command for the device B is appropriate (step S6). If the command is appropriate, the command for the device B is used as a control signal from the signal transmission unit 15. Transmit (step S7).
In step S5, if it cannot be recognized in direction 2, it is determined whether or not it can be recognized in direction 3 (step S8). If the direction 3 can be recognized, it is determined whether or not the command for the device C is appropriate (step S9). If the command is appropriate, the command for the device C is used as a control signal from the signal transmission unit 15. Transmit (step S10).
In step S8, if it cannot be recognized in direction 3, it is determined whether or not it can be recognized in direction 4 (step S11). If the direction 4 can be recognized, it is determined whether or not the command for the device D is appropriate (step S12). If the command is appropriate, the command for the device D is used as a control signal from the signal transmission unit 15. Transmit (step S13).
In step S11, when the direction 4 cannot be recognized, it is determined whether or not the handwriting input is completed (step S14), and when the handwriting input is continued, the process proceeds to step S2 to recognize the direction. Continue processing. In step S14, when the handwriting input is finished, the device control process is finished.
When the example of FIG. 8 is applied to this, the input for the direction 4 (270 ° 6) is recognized as a command for the device D (air conditioner) (set the set temperature to 6 ° C.), and this is for the device D (air conditioner). It is determined whether or not the command is appropriate. Since 6 ° C is outside the registered appropriate set temperature range, it is determined as an inappropriate command and is not transmitted.

As described above, according to the first embodiment, the CPU 11 detects the drawing direction input to the touch panel 3 and selects the control target based on the detected drawing direction. A control command for the control target is transmitted from the wireless transmission unit 16 via the signal transmission unit 15 based on the input drawing.
Therefore, different types of controlled devices can be remotely controlled by a very simple operation without providing special hardware.

  The drawing input is not limited to numbers. In addition to numbers, letters, symbols, figures, or a combination of two or more of these may be used. Further, the difference in the direction (angle difference) of the remote controller 1 may be not only 90 ° but also a smaller angle difference. In short, if the drawing input that can be recognized by the CPU 11 and the direction (angle) of the drawing input can be analyzed, the form of the control command to be input and the angle difference of the remote control device 1 are arbitrary.

Next, a second embodiment of the present invention will be described.
FIG. 13 is a plan view of the remote control device 1 according to the second embodiment, and shows a relationship between the orientation of the remote control device 1 and a handwritten input figure. FIGS. 13A and 13B in which the star mark 4 is directed upward (0 °) represent control commands for the television / video apparatus. As shown in FIG. 13 (1), the volume of the television is increased when the “∧” figure is drawn, and the video is fast-forwarded when the “>” figure is drawn. On the other hand, FIGS. 13 (3) and (4) in which the star mark 4 is oriented obliquely upward to the right (about 315 °) represent control commands for the air conditioner equipment. As shown in FIG. 13 (3), the set temperature is increased when the figure “∧” is drawn, and the air volume is increased when the figure “>” is drawn.
Therefore, similarly to the first embodiment, different types of controlled devices can be remotely controlled by an extremely simple operation without providing special hardware.

Next, a third embodiment of the present invention will be described.
FIG. 14 is a plan view of the circular remote controller 1 according to the third embodiment, and shows the relationship between the orientation of the remote controller 1 and the handwritten input Katakana character “M”. As shown in FIG. 14A, when “M” is drawn with the star mark 4 facing upward (0 °), a control signal for executing a mail check of the personal computer device is transmitted. As shown in FIG. 14 (2), when “M” is drawn in a direction in which the star mark 4 is obliquely lower left (120 °), a control signal for displaying a video menu screen such as an HDD or DVD Send. As shown in FIG. 14 (3), when “M” is drawn in a direction in which the star mark 4 is obliquely lower left (240 °), a control signal for displaying a music menu screen is transmitted.
Therefore, similarly to the first embodiment, different types of controlled devices can be remotely controlled by an extremely simple operation without providing special hardware.
The coordinates in the third embodiment may be polar coordinates with the center position of the touch panel 3 as the origin.

  In the above-described embodiment, the invention of the device that executes the device control processing program stored in advance in the program ROM of the CPU 11 has been described. However, the device is recorded on an external storage medium such as a flexible disk (FD), CD, or memory card. It is also possible to install a program for processing in the flash ROM 14 and execute the program by the CPU 11. In this case, the invention of the program and the invention of the recording medium on which the program is recorded can be realized.

  That is, the device control processing program according to the present invention is based on the step A for detecting the drawing input, the step B for detecting the drawing direction detected by the step A, and the drawing direction detected by the step B. The step C for selecting a control target and the step D for transmitting a control command for the control target selected in the step C based on the input drawing are executed.
