Information technologies have made significant changes in the world and newer developments in the field are transformational to societies today. For instance, fiber optics have made the telecommunication costs go down drastically. Another major development is in the speed and capacity of information systems. Both speed and capacities of systems are increasing but size of equipments or systems is decreasing. These reduced sizes combined with reduced costs have made possible human-computer interfaces that using virtual space transactions. This human-machine interface technologies have given rise to the field of robotics which is seeing many advances and is expected to grow fast in future.
