A holographic teacher took the world's first long-distance maths lesson at an educational IT technology show last week. Pupils were able to make eye-to-eye contact and hold conversations with a lifesize image of the teacher projected into a classroom.
The system, demonstrated by Internet firm Edex, uses a video camera and a PC to encode a digital image of the teacher, which is transmitted over the Internet to a special display in classrooms. Carolyn Evans, deputy headteacher of Graveney school, in London, which took part in the experiment, said the technology would open many new doors in education. "The speed of transmission of teleportation conferencing means that natural eye-to-eye contact and true-to-life virtual discussions can be carried out with ease," she said.
