An anonymous reader writes: "The basic idea is that an electronic device that produces random static noise may be affected by an observer if that static noise is based on the state of subatomic particles. This interaction of the user with the device can be measured and used as a form of input. An interesting aspect of quantum physics is that when a subatomic particle is observed its state changes (its wave function collapses), and the new state that it assumes cannot be predicted. Various theories exist as to why a particle assumes whatever state it does when its wave function collapses. One theory is that the observer is somehow interacting with the particle, causing it to assume its new state. Researchers at Princeton's Engineering Anomalies Research (PEAR) lab have amassed statistically significant data that says that an observer affects the new state of the observed particles. In some way, our mind interacts with these particles, and this interaction can be measured. IBM wants to use this measurement to create a new type of input device that basically reads your mind, no wires attached. IBMs Patent, PEARs Website. Incidentally, the inventors of this patent are a who's-who of the members of PEAR. Particularly Jahn and Dunne."
