Embodiment

[0029] As attached figure 1 As shown, OFN2 replaces the switch of the usual microphone, and has a song control function; this embodiment uses a wireless microphone 1, using 2.4G wireless communication to transmit audio and control information, and communicate with the karaoke host 3; compared to infrared transmission, 2.4G wireless is not affected by the direction, and has enough bandwidth to transmit audio; OFN can also be installed on a wired microphone, at this time, an additional communication line needs to be added.

[0030] Press OFN lightly, the controller in the microphone detects the signal, turn on the microphone power,

[0031] After the karaoke machine displays the boot screen, enter the main menu. At this time, slide your finger in the vertical direction of the OFN surface to select the main menu items: NUMBER (song number order), RECORD (recording), SINGER (singer order), LANGRAGES (language selection), PROGRAM (reservation song), each finger Swipe up and down to mo...

Abstract

The invention relates to a karaoke song requesting and control method based on optical finger navigation. The method includes the following steps that firstly, an optical finger navigation module OFN is installed on a karaoke microphone; secondly, the microphone with the OFN is in communication connection with a karaoke host; thirdly, the host judges the direction according to motion of one finger of a user through the OFN, calculates displacement and speed values in the horizontal direction and the vertical direction, and controls song list rolling, the same-layer menu switch and the different-layer menu switch according to parameters. Compared with the prior art, the karaoke song requesting and control method has the advantages that the microphone and a remote control unit are integrated, the sliding mode of the finger more accords with mental impression of the user, and song requesting operation of karaoke is greatly facilitated.

Description

Technical field [0001] The invention relates to a karaoke song order and control method, in particular to a karaoke song order and control method based on optical finger navigation. Background technique [0002] The Optical Finger Navigation (OFN) module has been used in mobile phones, but it has not yet been used in karaoke songs. And the operation method on the mobile phone is not suitable for karaoke to order songs. The main difference is that karaoke has a long list of songs, and the graphics displayed on the TV are large, and the corresponding moving range is large. [0003] At present, the general karaoke equipment uses the remote control to order songs. When singing, the microphone and the remote control are often required at the same time, which is extremely inconvenient to use. It is a good way to combine the microphone and the remote control, so you need to install a lot of buttons on the microphone. However, usually the space on the microphone is limited, and the butto...
