Description

  The present invention relates to a transmission apparatus suitable for a remote controller for remotely operating a device, for example, and an operation system including a transmission apparatus and a reception apparatus.

2. Description of the Related Art Conventionally, there is an apparatus provided with a ring-shaped input device as a remote control for operating an AV device such as a digital television (see Patent Document 1).
In this apparatus, the input device accepts a plurality of operations such as a rotation operation and a direction designation operation by the user, detects a rotational position that changes every moment by the rotation operation, and detects a designated direction by the direction designation operation.

The remote control device adds a header and a trailer to the detected data and transmits it as transmission data to the AV device at a specified transmission speed according to a specified protocol.
When the AV device receives the transmission data, the AV device decodes the rotation position and the designated direction indicated by the data, and performs processing such as moving a cursor displayed on the GUI screen by a rotation operation, for example. This process is continued according to the contents of the received data every time transmission data is received.
JP 11-338622 A

By the way, the speed at which the input device is operated varies depending on the person or the physical condition and emotion during the operation, and may be fast or slow.
On the other hand, the data transmission speed from the remote control device to the AV device is determined by the protocol and is constant.
In this case, there is no problem if the time interval for detecting the user's operation is longer than the transmission interval corresponding to the data transmission speed to the AV device. However, if the time interval is short, the detected data cannot be transmitted in real time. Once stored in the buffer in the remote control device, it is read out and transmitted at transmission time intervals. Such an operation becomes more prominent as the user's operation speed increases, and the user's operation is not transmitted to the AV device in real time. As a result, despite the operation of moving the cursor on the remote control device, the AV device cannot follow in real time, which is inconvenient for the user.

In the above description, the remote control device has been described as an example. However, the present invention is not limited to this, and is a problem common to a transmission device that generates data according to a user operation and sequentially transmits the data.

  As a result, even if the data transmission speed of the transmission device is relatively low and a large amount of operation data converted from user operations is generated within a short time, the transmission device can be operated in a single transmission. A plurality of quantized data obtained by quantizing data and reducing the number of bits can be included in transmission data that is data to be transmitted. Accordingly, the number of operation data waiting to be transmitted can be reduced as compared with the case where one operation data is included in transmission data and sequentially transmitted, and as a result, a situation in which the user's operation contents are reflected in a delayed manner can be prevented. Therefore, the operability of the transmission device can be improved.

<Embodiment 1>
Hereinafter, transmitting apparatus 100 and receiving apparatus 200 according to Embodiment 1 of the present invention will be described.
FIG. 1 is an overview diagram of transmitting apparatus 100 and receiving apparatus 200 according to Embodiment 1 of the present invention.

The transmission device 100 is a so-called remote controller, and receives an operation of a user, and transmits an infrared signal having a data structure according to the standard of the home appliance association shown in FIG. 17, for example.
Explaining this by taking the home appliance association standard as an example, the data structure of the infrared signal is composed of a header, a manufacturer code, a parity, a device code, a data part, and a trailer, and the data part can store 8-bit data.

In addition, the minimum transmission interval of the infrared signal transmitted by the transmission device 100 is 120 milliseconds, and command information indicating which button of the remote controller is pressed is stored in an 8-bit data portion. The infrared signal is not transmitted until the user performs an operation, but when the operation is performed, the transmission is started within a predetermined time.
Furthermore, the transmission device 100 includes a ring-shaped operation unit 11 as illustrated in FIG. 1, and the user presses and holds an arbitrary point of the operation unit 11 on the operation unit 11 for a predetermined time or longer. Three operations can be performed: a rotation operation of tracing the operation unit 11 along the circumference of the ring, and a direction specifying operation of performing an operation of pressing and releasing an arbitrary point on the operation unit 11 within a predetermined time.

With these three operations, the user can use functions that can be executed by the receiving apparatus 200, for example, functions such as mute and thumbnail selection.
The receiving device 200 is a digital television, and performs processing for receiving a digital broadcast and displaying a broadcast program, processing for reflecting an operation performed on the transmitting device 100 on a GUI screen, and the like.

<Configuration>

As illustrated in FIG. 1, the transmission device 100 includes an operation unit 11, a storage unit 12, a transmission unit 13, and a control unit 14.

  The operation unit 11 is a ring-shaped touch panel, and when the user touches the operation unit 11, the position where the user touches is detected by a change in voltage and is output as position information. As shown in FIG. 4, the position information is a value obtained by digitizing an angle in units of 2 ° with 0 ° in the clock 12 o'clock direction and positive in the clockwise direction, and outputs a value from 0 to 179. Specifically, assuming that an angle indicating a position where the user touches the operation unit 11 when the clockwise direction from the 12 o'clock direction is positive is θ, the position information is 2 × n ≦ θ <2 × (n + 1). In addition, the value of n satisfies 0 ≦ n <180. Since the output position information is in the range of 0 to 179, it can be represented by 8 bits.

The storage unit 12 is a memory for storing position information output by the operation unit 11 and time information indicating the time point when the position information is output. The time information is stored in the storage unit 12 by the control unit 14 when the control unit 14 measures the time when position information is output from the operation unit 11. The position information and time information are collectively referred to as operation information.

  The control unit 14 includes a central processing unit (CPU), a read only memory (ROM), a random access memory (RAM), and the like, and has a timekeeping function. When the position information output by the operation unit 11 is received, the time point when the position information is output is measured in milliseconds and output as time information. Further, a process for reducing the amount of data by performing a quantization process for quantizing the position information output from the operation unit 11, a process for storing the quantized position information in the storage unit 12, and for transmitting to the receiving device 200. A process of generating transmission data that is the data of the above, a process of transmitting the transmission data to the receiving apparatus 200 by controlling the transmission unit 13 and the like are performed.

<Operation>
Hereinafter, as an example of the operation of the transmission device 100 and the reception device 200 having the above-described configuration, two quantized position information is stored in the 8-bit data portion of the transmission data transmitted by the transmission device 100. This will be described with reference to FIG.
FIG. 3 is a diagram illustrating processing performed by the control unit 14 of the transmission device 100.

  The control unit 14 stands by until there is a user operation (S31: N). When the user contacts the operation unit 11 (S31: Y), the position at which the user contacts the operation unit 11 via the operation unit 11 The position information indicating is acquired. At this time, the time information indicating the point in time when the position information is output is acquired using the timekeeping function of the device itself (S32). The acquired position information is subjected to quantization processing for reducing the number of bits (S33).

In order to perform the quantization process, first, it is necessary to determine the number of quantization bits indicating how many bits the position information is represented by performing the quantization process. The number of quantization bits is determined by the total number of bits of the data part of the transmission data transmitted by the transmission device 100 and the number of quantized position information stored in the data part.
In the first embodiment, since the total number of bits in the data part is 8 bits and the number of positions where quantized position information is stored is 2, the number of quantization bits is 8 bits ÷ 2 = 4 bits. I want. When the number of quantization bits is obtained, a quantization coefficient indicating how many types can be expressed in the number of quantization bits is obtained. Since the number that can be expressed by 4 bits is 16 types of 0 to 15, the quantization coefficient is 16.

  When the quantization coefficient is obtained, a quantization table for quantizing the position information is obtained. The quantization table is represented by the following equation, where the quantization coefficient is m, the position at which the user touches the operation unit 11 is θ when the clock 12 o'clock direction shown in FIG. It is calculated according to the following [Equation 1]. A quantization table when the quantization coefficient is 16 is shown in FIG.

In addition, as shown in FIG. 4, the position information is a value obtained by quantifying the angle in units of 2 °, with the clock 12 o'clock direction being 0 °, clockwise being positive, and taking a value from 0 to 179. Keep in mind. That is, if the position information n = 45, θ = 90 °. Therefore, when the position information n = 45 is quantized with the quantization coefficient 16, the value after quantization processing is 4 according to FIG.
When the position information is quantized by the quantization coefficient 16, the control unit 14 stores the quantized data that is the quantized position information and the time information acquired in S32 in the storage unit 12 (S34).

The transmission device 100 generates sequential transmission data and transmits it to the reception device 200. However, when the control unit 14 acquires position information via the operation unit 11, the transmission unit 13 still transmits transmission data. If it is (S35: N), the control part 14 will acquire positional information via the operation part 11 in the meantime (S36).
When the transmission unit 13 does not transmit transmission data or when the transmission unit 13 completes transmission (S35: Y), the control unit 14 adds two 4-bit quantized data to the data portion of the transmission data. After storing and generating transmission data, all position information and time information stored in the storage unit 12 are deleted (S37). Thereafter, the transmission data is transmitted to the receiving device 200 via the transmission unit 13 (S38).

When the transmission is started, it is determined again whether or not the user has touched the operation unit 11 (S31), and the user's operation is accepted until the transmission is completed.
<Transmission data generation processing>
A supplementary description will be given of the transmission data generation processing in S37.
FIG. 6 is a diagram illustrating a process in which the control unit 14 generates transmission data.

In S34, the control unit 14 stores the quantized data obtained by quantizing the position information in the storage unit 12, and the quantized data is sequentially stored together with the time information.
The control unit 14 stores the quantized data having the latest time information in the lower 4 bits of the data portion 8 bits of the transmission data (S61). Subsequently, the quantized data having the time information closest to the predetermined time is stored in the upper 4 bits of the data portion 8 bits of the transmission data (S62).

Here, the predetermined time is a value obtained by subtracting 60 milliseconds, which is a half of the time required for the transmission apparatus 100 to transmit transmission data, from the time when the latest position information is acquired. When the time when the latest position information is acquired is shorter than the predetermined time, a time that is half of the predetermined time is newly set as the predetermined time.
In addition, when the number of pieces of position information acquired within a predetermined time is one, the number of pieces of quantized data to be transmitted is one type. In this case, quantized data having the same value is converted into a data portion of the transmission data. Are stored in the upper 4 bits and lower 4 bits.

When two quantized data are stored in the data portion of the transmission data, a transmission data having the data structure shown in FIG. 17 is generated by adding a header, a trailer, and the like (S63).
When the transmission data is generated, the control unit 14 deletes all position information and time information stored in the storage unit 12 (S64).
Next, the operation of receiving apparatus 200 will be described.

FIG. 7 is a flowchart showing processing performed by the control unit 24 of the receiving apparatus 200.
Each time the receiving unit 21 receives transmission data, the control unit 24 counts the reception interval, which is the time interval for receiving the header of each transmission data (S71), and stores the received data and time in the storage unit 22. The received reception interval is stored (S72). A plurality of quantized data included in the received data is extracted (S73), and an inverse quantization process for inversely quantizing the quantized data is performed (S74).

The inverse quantization table for inversely quantizing the quantized data is when the quantization coefficient is m, the value of the quantized data is d, the clock 12 o'clock direction shown in FIG. 4 is 0 °, and the clockwise direction is positive. Furthermore, when the position where the user touches the operation unit 11 is θ, it is obtained according to the equation θ = 360 × d ÷ m. An inverse quantization table when the quantization coefficient is 16 is shown in FIG.
In addition, as shown in FIG. 4, the position information is a value obtained by quantifying the angle in units of 2 °, with the clock 12 o'clock direction being 0 °, clockwise being positive, and taking a value from 0 to 179. Keep in mind. That is, if the value of the quantized data is 1, θ = 23, and the position information is a value of n satisfying 2 × n ≦ θ <2 × (n + 1) and 0 ≦ n <180. The value of the information n is 11.

Based on the plurality of position information obtained by the inverse quantization process in S74 and the reception interval timed in S71, the control unit 24 is any one of the long press operation, the rotation operation, and the direction specifying operation. (S75), the function corresponding to the user's operation is executed, and reflected on the GUI screen via the display unit 23.
<User operation determination process>
A supplementary description will be given of the user operation determination process performed by the control unit 24 in S75.

FIG. 9 is a diagram illustrating determination processing of a user operation performed by the control unit 24 of the reception device 200. The receiving device 200 sequentially receives data from the transmitting device 200.
When receiving the transmission data, the control unit 24 determines whether or not the reception interval timed in S71 is smaller than a predetermined time (S91).
If the reception interval is greater than the predetermined time (S91: N), it is determined that the user operation is a direction designation operation (S99). If it is less than the predetermined time (S91: Y), the difference between the lower 4 bits, which is the latest position information in the currently received data, and the position information expressed by the lower 4 bits in the previously received data, that is, the previous time And the angle change amount of the lower 4 bits of the position information received this time is calculated (S92). If there is no previously received data, the position change information of the previously received data is set to 0, and the angle change amount is calculated.

If the angle change amount is larger than the predetermined value (S93: N), it is determined that the user operation is a direction designation operation (S99). If it is smaller than the predetermined value (S93: Y), the angle change amount of the data received this time is calculated by obtaining the difference between the position information of the upper 4 bits and the lower 4 bits of the data received this time.
When the angle change amount of the data received this time is larger than the predetermined value (S95: N), it is determined that the user operation is a direction designation operation (S99). If it is smaller than the predetermined value (S95: Y), it is determined whether or not the angle change amount of the data received this time is zero (S96). If it is zero (S96: Y), the user's operation is long pressed. It is determined that the operation is an operation (S98). If it is not zero (S96: N), it is determined that the user operation is a rotation operation (S97).

  Note that the predetermined time in S91 and the predetermined values in S93 and S95 are set in advance in consideration of the operation characteristics of the operation unit 11 by the user and the members of the operation unit 11. The feature of the user operation is, for example, when the minimum data transmission interval of the transmission apparatus 100 of the first embodiment is 120 milliseconds. When the user operation is a long press operation and a rotation operation, the user operation Since the finger continues to touch the operation unit 11 of the transmission apparatus 100, the transmission apparatus 100 continues to generate transmission data, and as a result, the interval for transmitting data is 120 milliseconds, which is the minimum data transmission interval of the transmission apparatus 100. Close to. In the case of the direction specifying operation, compared to the long press operation and the rotation operation, the user's operation finger does not keep touching the operation unit 11, so the generation frequency of the transmission data is reduced, and as a result, the interval for transmitting the data Is larger than a long press operation or a rotation operation.

  Also, focusing on the amount of change in angle, which is the difference between the positions operated by the user, in the case of a long press operation, the operation finger of the user does not move, so the amount of change in angle is close to zero. From the limit of the operation speed of the rotational operation that can be physically operated with respect to the operation unit 11, the angle change amount becomes a certain value or less. In the case of the direction specifying operation, the angle change amount tends to be larger than that of the long press operation or the rotation operation.

Considering these features of the user's operation and the members of the operation unit 11, the control unit 24 can determine that the user's operation is a long press operation, a rotation operation, or a direction designation operation, a predetermined time in S91, A predetermined value of S95 is determined. For example, when the minimum data transmission interval of the transmission apparatus 100 described above is 120 milliseconds, the predetermined time of S91 is set to 140 milliseconds, the predetermined value of S93 is set to 160 or less, the predetermined value of S95 is set to 80 or less, and the like. can do.
<Embodiment 2>
Next, a transmission apparatus 100 and a reception apparatus 200 according to another embodiment 2 of the present invention will be described with a focus on differences from the first embodiment. The second embodiment is characterized in that an operation feature amount that is a value useful for determining a user operation is calculated based on a plurality of pieces of position information and time information.

<Configuration>
The control unit 14 of the transmission device 100 performs processing such as calculation of an operation feature amount.
In addition, the storage unit 22 of the reception device 200 stores the operation feature amount included in the received data, and the control unit 24 performs a process of determining an operation performed by the user based on the operation feature amount.
<Operation>
Hereinafter, operations of transmitting apparatus 100 and receiving apparatus 200 according to Embodiment 2 will be described with reference to the drawings.

FIG. 10 is a diagram illustrating processing performed by the control unit 14 of the transmission device 100.
The control unit 14 stands by until there is a user operation (S101: N), and when the user contacts the operation unit 11 (S101: Y), the position at which the user contacts the operation unit 11 via the operation unit 11 The position information indicating is acquired. At this time, the time information indicating the point in time when the position information is output is acquired using the timekeeping function of the device itself (S102). The acquired position information and time information are stored in the storage unit 12 (S103).

The transmission device 100 generates sequential transmission data and transmits it to the reception device 200. However, when the control unit 14 acquires position information via the operation unit 11, the transmission unit 13 still transmits transmission data. If it is (S104: N), the control part 14 will acquire position information via the operation part 11 in the meantime (S105).
When the transmission unit 13 is not transmitting transmission data, or when the transmission unit 13 completes transmission (S104: Y), the control unit 14 stores the position information and time information stored in the storage unit 12. In addition, a 4-bit operation feature value is calculated, and a quantization process for quantizing the latest position information is performed to generate 4-bit quantized data (S106). The operation feature amount and the latest position information are stored in the data part of the transmission data, and when the transmission data is generated, all the position information and time information stored in the storage unit 12 are deleted (S107). Thereafter, the transmission data is transmitted to the receiving apparatus 200 via the transmission unit 13 (S108).

When the transmission is started, it is determined again whether or not the user has touched the operation unit 11 (S101), and the user's operation is accepted until the transmission is completed.
<Operation feature amount>
The processing for calculating the operation feature amount in S106 will be supplementarily described with reference to the drawings.
FIG. 11 is a diagram in which operation feature amounts are defined.

The operation feature amount 1 is an average value of the time interval at which the operation unit 11 outputs position information, and the operation feature amount 2 is a standard deviation of the time interval at which position information is output.
The operation feature amount 3 is an average value of the angle change amounts representing the differences between the plurality of pieces of position information output by the operation unit 11, and the operation feature amount 4 is a standard deviation of the angle change amount.
The operation feature amount 5 is an average of angular velocities, which is a value obtained by dividing the angle change amount by the time interval at which position information is output from the operation unit 11, and the operation feature amount 6 is a standard deviation of the angular velocity.

The operation feature amount 7 is the number of pieces of operation information acquired within a predetermined time, and the operation feature amount 8 is a temporary determination result calculated based on a plurality of operation feature amounts. The provisional determination result of the operation feature amount 8 is a provisional determination as to whether the user operation is a long press operation, a rotation operation, or a direction designation operation.
In order to obtain a provisional determination result of the operation feature amount 8, the operation determination of the user operation is performed for each of the operation feature amount 1 to the operation feature amount 7, and the obtained seven operation determination results are integrated. Thus, a temporary determination of the user operation is performed.

In S106, since the temporary determination result of the operation feature amount 8 is calculated, in order to calculate the temporary determination result, the operation determination of the user operation is performed for each of the operation feature amount 1 to the operation feature amount 7, A method of integrating the obtained seven operation determination results will be described.
First, a method for determining the operation of the user operation for each of the operation feature 1 to the operation feature 7 will be described with reference to the drawings.

FIG. 12A illustrates a case where a user operation is assumed to be a rotation operation when the data transmission interval of the transmission device 100 is 120 milliseconds and the minimum time interval for the operation unit 11 to output position information is 15 milliseconds. It is an example of the threshold value of the operation feature-value for determining.
“D” in FIG. 12A represents the value of the operation feature amount actually acquired. Specifically, for example, if the average of the time intervals at which the operation unit 11 outputs the position information of the operation feature amount 1 is 20 milliseconds, with reference to FIG. 12A, D = 20 <25. Therefore, it is determined that the operation feature amount 1 is a rotation operation.

Referring to FIG. 12 (a), the operation feature value threshold value is D <15 for operation feature value 2, 2 <D <20 for operation feature value 3, D <35 for operation feature value 4, and operation feature value. The amount 5 is set as 5 <D <200, the operation feature amount 6 is set as D <60, and the operation feature amount 7 is set as D> 5.
FIG. 12B is an example of a threshold value of an operation feature value for temporarily determining that the user's operation is a long press operation. The operation feature value 3 is D ≦ 2, the operation feature value 4 is D ≦ 5, and the like. And a threshold is set. The operation feature values 1, 2, 5, 6, and 7 are not shown in FIG. 17B because the same values as those in FIG. 17A are set.

When the operation feature quantity does not satisfy both FIG. 12A and FIG. 12B, it is determined as the direction designation operation.
Next, a process of integrating the obtained seven operation determination results and calculating a temporary determination result of the operation feature amount 8 will be described with reference to the drawings.
FIG. 13 is a flowchart illustrating processing when the control unit 14 obtains a temporary determination result of the operation feature amount 8.

The control unit 14 determines, for each of the operation feature amounts 1 to 7, whether the user operation is a long press operation, a rotation operation, or a direction designation operation (S131), and the operation feature amount 3 And 5 are determined to be long press operations (S132: Y), it is temporarily determined that the user operation is a long press operation (S135).
If it is determined in S132 that the operation is not a long press operation (S132: N), it is determined whether or not the operation feature quantities 1 and 2 are both determined to be direction designation operations (S133), and if it is determined to be a direction designation operation. (S133: Y), the user's operation is tentatively determined as a direction designation operation (S136).

  If it is determined in S133 that the operation is not a direction designation operation (S133: N), it is determined whether or not four or more operation feature amounts among the operation feature amounts 1 to 7 are determined as rotation operations (S134). If four or more are determined to be rotation operations (S134: Y), the user operation is provisionally determined to be a rotation operation (S137). If four or more operation feature quantities are not determined to be rotation operations in S134 (S134: N), the user operation is provisionally determined to be a direction designation operation (S136).

In this way, a temporary determination result of the operation feature amount 8 can be calculated based on a plurality of position information and time information.
FIGS. 12A and 12B show examples of thresholds for determining whether the operation feature amounts 1 to 7 are rotation operations or long-press operation operations. These threshold values are set in advance in consideration of the characteristics of the operation performed by the user on the operation unit 11 and the members of the operation unit 11.

Features of operations performed by the user on the operation unit 11 by taking as an example a case where the data transmission interval of the transmission device 100 is 120 milliseconds and the minimum time interval for the operation unit 11 to output position information is 15 milliseconds. Will be explained.
Speaking of the average value and standard deviation of the time intervals at which the operation unit 11 outputs the position information of the operation feature quantities 1 and 2, when the user operation is a rotation operation or a long press operation, the operation finger of the user operates In order to keep in contact with the part 11, the position information continues to be output at the shortest output interval. Therefore, the operation feature quantity 1 that is an average of the time intervals at which the operation unit 11 outputs the position information substantially coincides with the shortest output interval. Since the position information continues to be output at the shortest output interval, the variation in the output value is smaller than that in the direction specifying operation. Therefore, the operation feature amount 2 which is the standard deviation of the time interval of the output position information. Is smaller than the direction specifying operation.

When the user's operation is a direction specifying operation, the time from when the operation finger contacts the operation unit 11 until the next contact tends to be longer than the shortest output interval due to the limit of the user's operation speed. The operation feature amounts 1 and 2 tend to be larger than the rotation operation and the long press operation.
Speaking of the average and standard deviation of the difference in the angle change amount between the operation feature amounts 3 and 4, when the user's operation is a rotation operation, there is a limit to the speed at which the user can perform the operation while touching the operation unit 11 with the operation finger. Therefore, the operation feature amount 3 that is an average of the angle change amounts is equal to or less than a certain value. In addition, since the angle change amount changes smoothly, there is little variation compared to the direction specifying operation. Therefore, the operation feature amount 4 which is the standard deviation of the angle change amount tends to be smaller than the direction specifying operation. .

In the case of a long press operation, since the user's operation finger does not move, the amount of change in angle is close to zero. Therefore, the operation feature amounts 3 and 4 are both zero or a value close to zero.
In the case of the direction specifying operation, the value of the angle change amount varies, so that the operation feature amounts 3 and 4 tend to be larger than those of the rotation operation and the long press operation.
Speaking of the average and standard deviation of the angular velocities of the operation feature quantities 5 and 6, when the user's operation is a rotation operation, there is a limit to the speed at which the user can operate with the operation finger in contact with the operation unit 11, and zero. Therefore, the operation feature amount 5 that is an average of the angular velocities is a value that falls within a certain value. Also, since the angle change amount changes smoothly and becomes a substantially constant value, and the variation is less than that in the direction designation operation, the operation feature amount 6 which is the standard deviation of the angular velocity is less than a certain value.

In the case of a long press operation, the angular velocity is close to zero because the user's operation finger does not move. Therefore, the operation feature amounts 5 and 6 are both zero or a value close to zero.
In the case of the direction specifying operation, the value of the angular velocity varies, and thus the operation feature amount 5 and the operation feature amount 6 tend to be larger than those of the rotation operation and the long press operation.
Speaking of the number of pieces of position information acquired within a predetermined time of the operation feature amount 7, when the user's operation is a rotation operation or a long press operation, the minimum time required for the user's operation finger to keep touching the operation unit 11. Since position information is output at intervals, the number of position information acquired within a predetermined time is the maximum value of the number of position information that can be acquired within a predetermined time or a value close to the maximum value.

In the case of the direction specifying operation, since the user's operation finger does not keep touching the operation unit 11, the value of the operation feature amount 7 is smaller than that of the rotation operation or long press operation.
As described above, by considering the features of the operation performed by the user on the operation unit 11 and the members of the operation unit 11, a threshold value of the operation feature amount for determining the user's operation can be set. .

<Transmission data generation processing>
The transmission data generation process performed by the control unit 14 in S107 will be supplementarily described with reference to the drawings.
FIG. 14 is a flowchart illustrating a process in which the control unit 14 generates transmission data.
The control unit 14 stores the quantized data obtained by quantizing the position information having the latest time information in the lower 4 bits of the data portion 8 bits of the transmission data (S141). Subsequently, the operation feature amount calculated in S106 is stored in the upper 4 bits (S142).

The temporary determination result of the operation feature value 8 only needs to be able to temporarily determine three operations, ie, a rotation operation, a long press operation, and a direction designation operation. Can be stored. For example, the rotation operation may be 0, the long press operation may be 1, the direction designation operation may be 2, and the like.
When the control unit 14 stores the temporary determination result of the operation feature 8 and the latest quantized position information in the data part of the transmission data, the control unit 14 adds a header, a trailer, and the like, and transmits the transmission data having the data structure shown in FIG. Is generated (S143).

When the transmission data is generated, all the operation information stored in the storage unit 12 is deleted (S144).
Next, the operation of receiving apparatus 200 will be described.
FIG. 15 is a diagram illustrating processing performed by the control unit 24 of the receiving device 200.
When the transmission data is received by the reception unit 21, the control unit 24 measures the data reception interval (S151), and stores the received data and the measured reception interval in the storage unit 22 (S152). The operation feature amount and quantized position information included in the received data are extracted (S153), and the user's operation is any of rotation operation, long press operation, and direction designation operation based on the operation feature amount and position information. It is determined whether or not there is (S154), the function corresponding to the user's operation is executed, and reflected on the GUI screen via the display unit 23.

The user operation determination process in S154 will be supplementarily described with reference to the drawings.
FIG. 16 is a flowchart showing a determination process of a user operation performed by the receiving apparatus 200. The receiving device 200 sequentially receives data from the transmitting device 200.
The control unit 24 determines whether or not the tentative determination result of the operation feature value 8 is a direction designation operation (S161), and if it is a direction designation operation (S161: Y), the transmission data received in S151 is received. It is determined whether or not the interval is smaller than the predetermined time (S162). When it is longer than the predetermined time (S162: N), the direction designation operation is determined as the final determination (S166).

  If it is less than the predetermined time (S162: Y), it is determined whether or not the difference between the position information received last time and the position information received this time is smaller than a predetermined value (S163), and if larger than the predetermined value (S163). : N), it is finally determined that the user operation is a direction designation operation (S166). When it is smaller than the predetermined value (S163: Y), the determination result of the previous user operation is set as the final determination (S165).

In S161, when the temporary determination result is not a direction designation operation (S161: N), it is determined whether or not the temporary determination result is a rotation operation (S164). When the temporary determination result is a rotation operation (S164: Y). ), The rotation operation is the final determination (S167). When it is determined that the rotation operation is not performed in S164 (S164: N), the long press operation is determined as the final determination (S168).
Note that the predetermined time in S162 and the predetermined value in S163 are set in advance in consideration of the operation characteristics of the user with respect to the operation unit 11 and the members of the operation unit 11. Since the feature of the user operation has already been described in the first embodiment, a description thereof will be omitted.

The predetermined time in S162 and the predetermined value in S163 are determined in consideration of the operation characteristics of the user and the members of the operation unit 11. For example, when the minimum data transmission interval of the transmission apparatus 100 is 120 milliseconds as in the first embodiment, the predetermined time of S162 can be set to 140 milliseconds, the predetermined value of S163 can be set to 160 or less, and the like. .
<Supplement>
Although the embodiments of the invention have been described above, it is needless to say that the present invention is not limited to the above-described embodiments.

  (1) In the second embodiment, the transmission device 100 calculates an operation feature amount that is a provisional determination result, and transmits the operation feature amount and the quantized position information to the reception device 200. On the reception device 200 side, Based on the data reception interval, the operation feature value stored in the received data and the quantized position information, it is finally determined whether the user operation is a rotation operation, a long press operation, or a direction specifying operation. However, the final determination of the user operation does not need to be performed on the reception device 200 side, and the user operation is performed on the transmission device 100 side based on the data transmission interval, the operation feature amount, and the quantized position information. The final determination result may be transmitted to the receiving apparatus 200.

(2) In Embodiment 1, two quantized data are always stored in the data part of the transmission data. However, it is not necessary to fix the two quantized data, and the quantum stored dynamically according to a predetermined condition. Alternatively, the number of digitized data may be determined.
The predetermined condition includes, for example, changing the number of quantized data stored in the data portion according to the number of position information output from the operation unit 11 within a predetermined time.

  That is, when the position information output within a predetermined time is small, the number of quantized data stored in the data part of the transmission data is reduced, and when the position information output is large, quantization stored in the data part is performed. By increasing the number of data, an optimal quantization coefficient can be set according to a user operation. As a result, when the output position information is small, data with a large quantization coefficient can be transmitted and fine operations of the user can be accepted, while when the output position information is large, more positions can be received. Information can be sent.

(3) In the first embodiment, transmission data is generated by storing two quantized data, and transmission of transmission data is started after the generation. In parallel with the transmission of one piece of quantized data, a user operation may be accepted and a quantization process may be performed, which may be stored in the subsequent 4-bit data and transmitted.
(4) In Embodiments 1 and 2, it is determined whether the operation performed by the user according to the flowcharts shown in FIGS. 9 and 16 is a rotation operation, a long press operation, or a direction designation operation. The method for determining the operation performed is not limited to the above-described method, and may be another method.

  (5) In the first and second embodiments, as shown in FIG. 4, the operation unit 11 sets a value obtained by quantifying the angle in units of 2 °, with the clock 12 o'clock direction set to 0 ° and the clockwise direction set to positive. Although it is output as information, it is not necessary to set the time of the clock at 12 o'clock as 0 °, and it is not necessary to digitize the angle in units of 2 °. In addition, when generating quantized data in which position information is quantized, a quantization table is obtained according to the equation shown in [Equation 1], but the quantization table is fixed to the equation shown in [Equation 1]. There is no need to do so, and the mathematical expression for obtaining the quantization table may be dynamically changed according to the user's operation.

  (6) In Embodiments 1 and 2, the case where the data portion of the transmission data is 8 bits has been described as an example. However, the size of the data portion is not limited to 8 bits, and the position information is quantized. In this case, the quantization coefficient 16 is used for quantization, but the quantization coefficient 16 is not necessarily limited. In the first embodiment, two pieces of quantized data are stored in the data portion. However, the number of pieces of quantized data to be stored is not limited to two.

(7) In the first and second embodiments, it has been described that the transmission device 100 is a remote controller and the reception device 200 is a digital television. However, the present invention is not limited to these devices. It may be a device or another device.
(8) In the first and second embodiments, the operations that can be performed by the user are the three operations of the rotation operation, the long press operation, and the direction specifying operation. However, the operations are not limited to these operations, and the slide operation, Other operations such as a double click may be used.

(9) In the second embodiment, the operation feature quantity stored in the data portion of the transmission data is the provisional determination result of the operation feature quantity 8. However, the present invention is not limited to this, and other operation feature quantities are used as the transmission data. The method for obtaining the provisional determination result is not limited to the method illustrated in FIG. 13, and other methods may be used.
(10) Embodiments 1 and 2 have been described using a ring-shaped input device. However, the present invention is not limited to a ring shape, and any shape such as a rectangle, a semicircle, or an arc Also good.

  The present invention can be used in an operation system including a transmission device such as a remote control device and a reception device such as a digital television and a recording device.
