A WiFi 3D Holographic Projector Hologram is available at electronic stores and is considered one of most accessible and affordable devices. In order to give the illusion that the 3D virtual objects are actually embedded in real life, it uses specialized software to create 3D movies with black backgrounds. The learner should avoid extending their hands too close to the projector in an attempt to grab the 3D virtual objects. Additionally, it does not provide sound, but external speakers can play 3D movies simultaneously through a computer or smart phone.
