Research that could lead to a system whereby your PC could read your thoughts is underway at Reading University in the UK. Professor Kevin Warwick, who earlier this year had a 64-bit chip sewn under the skin of his arm to turn himself into a walking smart card (CI No 3,483), now plans to go one step further. In a year’s time, he is planning to embed another chip in his arm just above the elbow – connected to his nervous system. Receiving signals from the device will be the one person who knows the professor better than most: his wife Irena. Initially, communications will be restricted to yes/no signals. But professor Warwick is working closely with neurosurgeons and sees the ultimate possibility that humans will be able to communicate with thought alone and give instructions to their PC without saying a word.
