Tele-surgery will be realized by bilateral robot and communication lines. The lecture will include the basis of real-world haptics on communication lines such as internet. Also it will cover possible applications in future, since this technique will enrich the vividness of the real-world and real-time information. The transmittal of force information is not easy since it is always bilateral. This means the real-world haptics inherently includes a natural feedback inside. Any delay of the communication will deteriorate the quality of the touching sensation. The lecture will give a key concept to know such issues and will show several solutions. The experimental results will be always given for well understanding. The audience will be sure that the bright future of multi-media communications based on human sensations will come soon.
