A "Virtual Idol" is a computer-generated character designed to perform music and entertain audiences, often resembling a human singer. These digital personas can sing, dance, and interact with fans through various media, including concerts, social media, and video games. They are created using advanced animation and artificial intelligence technologies. One of the most famous examples of a virtual idol is Hatsune Miku, a digital singer from Crypton Future Media. Virtual idols have gained popularity in countries like Japan, where they often collaborate with real artists and participate in live performances using holographic technology.
