However, a configuration may be adopted in which a communication unit that can transmit and receive IR signals is further provided to respond to control commands from a conventional remote control device that uses IR signals.

  Next, the remote controller 200 which is an embodiment as the specifying means of the present invention will be described. FIG. 3 shows an external appearance (front view) of the remote control device 200. A touch panel 207 is arranged at the center of the casing, and various displays are made to the user and the stylus 405 or a finger is brought into contact with the remote control device 200. Accept user input. In the present embodiment, only the touch panel 207 is used. However, the present invention is not limited to this embodiment. For example, the touch panel 207 is configured to accept user input using a display unit and various keys or only various keys. A well-known remote control form can be employed.

  A fingerprint reading unit 203 as an authentication unit is provided on the upper right of the touch panel 207. A fingerprint is read by the user sliding his / her finger on the fingerprint reading unit 203. Features of the read fingerprint are extracted as appropriate by an algorithm and converted into fingerprint information. The authentication means is not limited to this form, and various biometric authentications and various types using IDs and passwords can be employed.

Note that the input means is not limited to the touch sensor 206, and mechanical input means such as a keyboard and cursor keys may be employed.

The remote control communication unit 202 performs wireless communication with the wireless access point 70 in accordance with, for example, a wireless LAN standard (IEEE802.11a / b / g). In this remote control communication unit 202, the remote control device 200 communicates with the commander 300 and the host device 100. The remote control communication unit 202 can also be realized by, for example, the Bluetooth standard (registered trademark). In that case, the remote control device 200 and the commander 300 perform wireless communication by the communication unit of the same standard provided on the commander 300 side on the receiver side. Furthermore, the remote control device 200 communicates with the host device 100 via the commander 300.

  Various commands such as music designation from the remote control device 200 to the commander 300 are transmitted via the communication unit 202. That is, the remote control device 200 performs wireless communication with the wireless access point 70 arranged on the LAN.

  The fingerprint information read by the fingerprint reading unit 203 is used in an authentication process performed with the host apparatus 100, and a user who has succeeded in authentication can receive various services as a login user. Some users do not like fingerprint authentication as an authentication method for login. Therefore, in the karaoke system according to the present embodiment, authentication using the fingerprint reading unit 203, authentication by inputting a user ID from the touch panel 207, and a password can be selected.

  As mentioned above, although the hardware configuration in this system was demonstrated, next, the flow of the whole singing scoring process using these hardware configurations is demonstrated using FIGS. 5 is a diagram showing a flow of the singing scoring process, FIG. 6 is a diagram showing a communication process in the singing scoring process, FIG. 7 is a diagram showing ranking information, and FIG. 8 is a screen during playback. FIG. 9 is a diagram showing the ranking display screen A, and FIG. 10 is a diagram showing the ranking display screen B.

  In the flow of FIG. 5, when the user selects music using the remote controller 200, the music ID of the designated music is transmitted to the commander 300. In the present embodiment, this singing scoring process is a process that can be used by a logged-in user who has been successfully authenticated by the authentication means. Thus, if the singing scoring process is a member service for the logged-in user, the user information can be easily managed using the personal setting information. In addition, an increase in ranking information by guest users who are not logged in can be suppressed. In addition, you may make a guest user perform this song scoring process. In that case, the same effect can be obtained by prohibiting the update of the ranking information by the score of the guest user.

  In addition, the music ID is also transmitted to the host device 100, and the host device 100 is also notified of the music to be sung (S201). The commander 300 that has received the song ID reads out the performance information corresponding to the song ID and causes the sound source unit 307 to reproduce it. Further, the commander 300 starts the scoring process together with the reproduction of the performance information. This scoring process is a process well known in karaoke, and a score is calculated in comparison with melody information as a singing standard included in performance information. In the present embodiment, the score is calculated and output not only after the performance information has been reproduced, but also at an appropriate timing during the reproduction.

  On the other hand, the host device 100 that has received the song ID extracts ranking information corresponding to the song ID from the database, and uses it in the present song scoring process. FIG. 7 shows an embodiment of this ranking information, in which a user ID, a commander ID, and a score are described for each rank. The ranking information is sufficient to describe at least the score, but by managing the ranking, user ID, commander ID, etc., it is easy to handle the data, and various information about the user and the store, Various aggregate information can be provided. When the host device 100 extracts the ranking information, the host device transmits the higher ranking information to the commander 300 based on the ranking information. This high-ranking information is various information related to the high scorer, for example, a score related to a singer whose score is within 3rd place, and information related to the singer and the use store. Information on the singer includes a nickname, sex, age, etc., and is extracted from the database with reference to the user ID described in the ranking information. Further, the information relating to the store used is a store name, a chain store name, a location, etc., and is extracted from the database with reference to the commander ID. The commander 300 that has received the top ranking information superimposes and displays it on the karaoke background screen on the display 404 (S103), and visually conveys information on the top prize winners to the user.

The processes of S105 to S115 are repeated until the performance is completed. This process is performed at appropriate timing (for example, at intervals of 5 seconds). When the arrival of timing is determined in S105, the calculation is made in S106. This score is an average score up to the reproduction time point. For example, when the final score is 100 points, the full score up to the reproduction time point is also 100 points. In this way, by setting the score calculated during the reproduction as an average score, it is possible to determine the rank in comparison with the final score in the ranking information even during the reproduction.

  The score calculated in S106 is converted into a correction score by correction based on the correction coefficient in S107. This correction is a process for improving the game performance of the singing scoring process, and details thereof will be described later. In S108, the calculated correction score is compared with the ranking information to obtain an intermediate rank. In the present embodiment, every time a correction score is calculated, an inquiry is made to the host device 100, and the host device 100 compares the correction score with ranking information to determine the intermediate rank. The determined intermediate rank is transmitted to the commander 300. In addition, it is good also as not performing the correction process of S107 but performing intermediate rank based on the score calculated by S106, and calculating exact intermediate rank.

  In S109, it is determined whether the score calculation is the first time or the second time or later. In the first time, the score calculated in S106 in S110 and S111 and the intermediate rank acquired in S108 are displayed on the display 404. indicate. Note that the corrected score calculated in S107 may be displayed instead of displaying the score. In addition, these score and midway ranking display processing (processing surrounded by a broken line) may be omitted.

  On the other hand, if it is determined in S109 that the score has been calculated for the second time or later, the comparison rank is calculated in S112. This comparison order is a difference between the intermediate rank acquired in the current S108 and the intermediate rank acquired in the previous S108. In S113, the rank fluctuation is displayed based on the calculated comparison rank. The state of the screen during reproduction is shown in FIG. On the display 404, the lyrics 501 are displayed superimposed on the background video, and a rank change A502 and a rank change B503 are further displayed. The user can visually confirm the change in the order by referring to the order change A502 and the order change B503.

  The rank change A502 is an arrow-shaped icon indicating whether the rank has been raised, lowered, or the same as the previous halfway rank. The upward arrow in the display 404 in the figure indicates that the rank has risen. Show. In the present embodiment, as shown on the outside of the display 404, a horizontal icon is displayed as a change in rank A502 when there is no change in rank, and a downward icon is displayed when the rank is lowered.

The rank change B 503 is information indicating how many people have been removed from the previous halfway rank. For example, when the previous rank is 10th and this time is 5th , “5 missing” is displayed as shown in the figure. . The same display is performed when the ranking is lowered and there is no change. Note that the display of the rank fluctuation B503 may be displayed only when the rank is increased. Singers' motivation to sing can be increased. As described above, since the rank fluctuation A and the rank fluctuation B are displayed based on the comparison rank, the user can check the fluctuation status of the rank during singing. Note that the rank variation is not limited to these, and an appropriate form such as displaying the calculated comparison rank as it is, or changing the color and size of the icon of the rank variation A502 depending on the degree of increase or decrease can be adopted. .

In S114 and S115, as in S110 and S111, (correction) scores and intermediate ranks are displayed. However, in the present invention, the purpose is to notify the user of changes in rank based on the comparison rank. The processing of S115 (processing surrounded by a broken line) may be omitted. In this way, it is possible to improve the game performance of the singing scoring process by displaying only the rank change without displaying the mid-ranking in the middle of reproduction and displaying the final rank after the reproduction is completed. As described above, by repeating the processes of S105 to S115 in FIG. 5 and the process surrounded by the broken line in FIG. 6 during the performance information reproduction, the rank variation based on the comparison rank, which is a feature of the present invention, can be displayed on the display means. .

  When the performance information is reproduced to the end, or when the reproduction of the performance information is terminated by the user's reproduction termination instruction (S104), the recording process and the comparison process are also terminated, and the singing time that the user should originally sing in S116 It is determined whether or not the time is n% or more. This determination is made in order to prevent the ranking from being performed when the singing time is too short. If it is less than n%, a message indicating that scoring is impossible is displayed on the display 404, and then the singing scoring process is terminated (S120). In addition, it may replace with performing at the ratio of singing time and you may judge by having sung for predetermined time or more.

  On the other hand, when the singing time condition is cleared, the final score, the final ranking, etc. are displayed, and the ranking information is updated. In S117, the final score is transmitted to the host device 100, and the final ranking is acquired. A user ID and a commander ID may be transmitted together with the final score. These pieces of transmission information are used for updating the ranking information. As in S202, the host device 100 refers to the received final score as ranking information, calculates the final ranking (S203), and updates the ranking information with the received information (S204). At the time of update, only one record with the highest score may remain in one user's record, or multiple records of one user may be registered in the ranking information.

  After the ranking information is updated, the calculated final ranking is transmitted to the commander 300. At this time, various types of total information may be transmitted together. The commander 300 that has received the final ranking displays the ranking display screen A in S118. The state of the ranking display screen A is shown in FIG. Reference numeral 504 denotes related information of the music used in the singing scoring process, and the singing name and the music name are displayed. 505 is user related information of a singer, and is displayed based on personal setting information acquired when logging in. In the figure, a user's photograph or a user-related image such as an avatar and a nickname are displayed. A final score is displayed in 506, and rank-related information is displayed in 507. In the figure, as the ranking related information, a nationwide ranking, the total number of people, a score distribution, and a graph that can grasp the current score are displayed. On this ranking screen A, the singer can confirm the final score and the final ranking.

  When a predetermined time elapses after the ranking display screen A is displayed or when an operation by the user is performed, the display shifts to the ranking display screen B shown in FIG. On this screen, the user can reconfirm the final score and final ranking, and can also confirm information regarding ranking leaders acquired from the host device and rankings with different aggregation ranges. In the score related information 508 of this screen, in addition to the final score, the national average score of the music is also displayed. Also, ranking leader information 509 regarding the top three singers is displayed. The ranking superior information 509 includes a user-related image, a nickname, a chain store name, a store location, and the like in addition to the rank and score. Such information is obtained by referring to the database in the host device 100 based on the user ID and commander ID in the ranking information.

  In addition, the chain store ranking 510 and the store ranking 511 that are tabulated based on the commander ID described in the ranking information are also displayed. In this way, on the ranking display screen B, the user can confirm not only the final score and final ranking, but also various information related to the top prizewinners, ranking in a counting range other than nationwide counting, and the like. When a predetermined time elapses after the ranking display screen B is displayed, or when an operation by the user is performed, the singing scoring process ends (S120).

The overall flow of the singing scoring process has been described above. In the present embodiment, the communication process in which the host apparatus 100 is inquired for the intermediate rank at every predetermined timing is used. Instead of this communication process, ranking information is downloaded from the host apparatus 100 in advance, and the score on the commander 300 side is used as the ranking information. You may make it determine a ranking in comparison. In this case, although it cannot be compared with the ranking information updated in real time, the number of times of communication with the host device 100 can be reduced. Note that only the final ranking may be determined by comparing with ranking information managed by the host device 100.

  Next, the correction score calculation process (S107 in FIG. 5) in the singing scoring process will be described with reference to FIGS. FIG. 11 is a diagram showing the correction score calculation processing, FIG. 12 is a diagram showing a score coefficient list, and FIG. 13 is a diagram showing how the score coefficients change.

The correction score calculation process is executed at a predetermined timing such as every predetermined time (5 seconds). FIG. 11 shows a state from the start of reproduction of performance information to the end thereof. At the first predetermined timing after the performance information is started to be reproduced, the score a which is the average score from the reproduction start time is multiplied by the score coefficient 0.700 set at the first predetermined timing. A corrected score a ′ is calculated. At the second predetermined timing, the calculated score b is multiplied by the score coefficient 0.723 set at the second predetermined timing to calculate the corrected score b ′. Thereafter, the same processing is repeated at each predetermined timing, and correction scores are sequentially calculated.

FIG. 12 is a diagram showing a score coefficient list used in the correction score calculation process, and a score coefficient is set for each section corresponding to a predetermined timing. Since the total performance time differs for each piece of performance information, in this embodiment, a score coefficient list is created for each piece of performance information. First, a coefficient application time that requires a coefficient of 1.0 or less is calculated from the total performance time. For example, 80% of the total performance time is set as the coefficient application time. Then, the number of times of the predetermined timing is calculated based on the coefficient application time and the time interval of the predetermined timing. Next, the first scoring coefficient, 0.7 in the figure, is acquired.
Next, the final scoring coefficient is set to 1.0, and a coefficient increase with respect to the first scoring coefficient (difference between the final scoring coefficient and the first scoring coefficient) is calculated (in the example of the figure, 1-0.7 = 0.3). The increase amount of this coefficient is divided by the number of predetermined timings, the increase amount at each predetermined timing is calculated, and the score coefficient at each predetermined timing is determined.

The state of the score coefficient transition determined by this embodiment is shown in FIG. 0 for the first time.
It can be seen that the score coefficient set to 7 changes linearly until it reaches 1.0 after the coefficient application time. In this way, by correcting the score with the score coefficient that increases with the progress of the performance and calculating the midway rank, the score is lowered at the beginning, returning to the original score as the performance progresses, and the midway rank increases. The game performance of the singing scoring process can be improved. Further, when the song is not sung to the end, the correction score is smaller than the original score, so that it is effective as a penalty for a singer who has not sung until the end.

  The score coefficient is not only changed to a linear shape as in the present embodiment, but can be selected as appropriate, and may be changed nonlinearly as shown in B and C. Furthermore, in the present embodiment, the score coefficient list is calculated based on the total performance time, but a score coefficient list prepared in advance may be used. In such a case, a plurality of score coefficient lists corresponding to the total performance time are prepared and used by switching to cope with the difference in the total performance time for each music piece.
