Abstract
The present invention provides a system for pitch correction. The interactive surface is embedded with a host, an antenna, a memory unit, a voice input device, an audio recognition device, and a media player. The function of each light-emitting contact point is determined or changed by the host in accordance with preset programs. Each physical sheet is embedded with an RFID tag and is printed with a set of pitch marks with increasing difficulty levels, and the location of a functioning area on a physical sheet for the light-emitting contact points is determined in accordance with the preset programs, and the light-emitting contact points correspond to the location of the functioning area. Once a physical sheet is placed on the interactive surface, the host assigns preset flashing rules to the array of light-emitting contact points in accordance with the preset programs as well as the RFID tag embedded in the physical sheet, and generates a preset flashing pattern on the physical sheet, and activates touch functions of the corresponding light-emitting contact points. The visible feedback provides users a straightforward understanding how much their voices deviate from the reference …
