[0029] A. Karaoke Mode

[0030] Entertainment device 10 may operate in a karaoke mode in which entertainment device 10 plays the instrumentals of a chosen song and guides a user through the song by displaying words of the song on a display device 16. Central processing unit 12 communicates with memory device 18 and displays a song selection screen 28, as shown in FIG. 6, on display device 16. A user may scroll through multiple screens containing lists of songs using controls 25 on input device 20, controls on central processing unit 12, or with other devices. In one embodiment, a user may scroll through the songs using keys that may be labeled “up” or “down” on input device 20. A song may be selected using a key labeled “select” 42. A user may select more than one song to be played in the ordered selected. In one embodiment, a user may select up to five songs to be played in successive order. The list of songs displayed on display device 16 may include song titles and the artists performing each song. In addition, the songs may be grouped into classifications, such as by song type.

[0031] The words of the song are displayed by central processing unit 12 on display device 16, as shown in FIG. 7. The words may be displayed in multiple lines and scroll downwardly on display device 16. Entertainment device 10 indicates to a user when each word should be sung. In one embodiment, each word may be highlighted, displayed in a color that is different than the other words displayed on the screen, or otherwise brought to the attention of a user when that individual word or phrase should be sung. While a song is being displayed on display device 16, central processing unit 12 may play the background music for the song through speakers 23. The user may adjust the volume, pitch, and tempo of the song being played by using controls 25, which may be on input device 20 or on control processing unit 12. An additional input device 16, such as a microphone, may be coupled to central processing unit 12 so that another user may sing together with the first user to form a duet. After the song has been completed, central processing unit 12 may display mode selection screen 26.

[0032] B. Dance Mode

[0033] Entertainment device 10 may operate in dance mode where a user dances on mat 14 to a song selected by the user. A user may select a song from a list of songs. The central processing unit 12 plays the song, with or without lyrics. A user may also select the level of difficulty of the dance, such as easy, regular, or hard. Once the difficulty level has been selected, the user depresses the “start” button to play the selected song. While the song is being played, display device displays a screen, such as the dance screen 30 shown in FIG. 8. Dance screen 30 displays arrows in target box 32 pointing to the location that the user should place his or her feet on mat 14. If the user correctly places his or her feet on the correct location on mat 14 and the timing is correct, the arrow on the screen may be highlighted, which signifies a correct step was made by the user.

[0034] Entertainment system 10 assigns points to the user that are recorded in what may be referred to as a “life meter” 34. The objective for the user is to step on the correct footprint 24 located on mat 14 that corresponds with the arrow that is shown in target box 32. The amount of points are tracked and displayed on display device 16. When the user misses an arrow, points are subtracted from life meter 34. When life meter 34 falls to zero, the game is over. The display device 16 may display the word “failed” on the screen. Display device 16 may display the percentage of correct dance steps made, the highest score obtained by any user, and other information. After a few moments, display device 16 will display song selection screen 28.

[0035] C. Karaoke and Dance Combination Mode

[0036] Entertainment device 10 may include a karaoke and dance combination mode. After a user has chosen the karaoke and dance combination mode icon from mode selection screen 26, song selection screen 28 is displayed. A user may select one or more songs to be played in successive order. Once a user has finished selecting the one or more songs, the user may actuate a “start” button 50. Display device 16 then may give the user the ability to choose the difficulty level of the song and dance, such as, easy, regular, and hard. The user can then actuate the “start” button 50, which will cause the central processing unit 12 begin playing the song. While the song is being played, display device 16 will display the words to the song, as described above for the karaoke mode, and will display target box 32 for guiding the user through the proper dance steps. The user may adjust parameters, such as volume, pitch, an tempo of the song being played. If the user losses all of his or her points target box will stop displaying arrows, but entertainment device 10 will continue to display the words to the song until the song has been completed. At the conclusion of the song, the user's percentage of correct dance steps are displayed. The display device 16 then displays mode selection screen 26.

[0037] D. Competition Mode

[0038] Entertainment device 10 may include a competition mode enabling two or more users to compete against each other. For the entertainment device 10 to operate in competition mode, the central processing units 12 of two mats 14 should be place in communication with each other. In one embodiment, this may be accomplished using a challenge wire. The challenge wire may be formed from an insulated conductive wire having connectors at each end that are capable of being coupled to mats 14. A memory device 18 needs to be placed in only one of the central processing units 12. The power may be turned on when desired, and the first user can select the difficulty level, which may be, but is not limited to, easy, regular, or difficult. The first user may then press the “start” button to start the competition.

[0039] The competition mode screen 36, as shown in FIG. 9, is displayed, which may include a life meter 34 for each user, a scoring box 38 for each user, and a target box 32 for each user. Competition mode screen 36 may be divided vertically in the middle of the screen, whereby a first user's statistics may be displayed on one side of the screen and a second user's statistics may be displayed on another side of the screen. The users dance in the same manner as described above for the dance mode by following the arrows displayed in target box 32. The score for each user is displayed in the scoring boxes 38. If one of the users' score falls to zero while a song is being played, that user's game is ended and a word, such as “failed,” appears on the screen. The other user is able to continue dancing until the song has ended. At the end of the song, the users' statistics may be briefly displayed on the screen. The mode selection screen 26 may be displayed by a user depressing a “main menu” button.
