"Many computer scientists around the world are involved in the same field, commonly known as brain computer interfaces, or direct neural interfaces. But many other projects are focused instead on the concept of directly controlling the computer with brain waves, such as an alternative method of moving the cursor on the screen.
With its approach, the Microsoft project is aiming for something that could be adopted on a larger scale, Tan said. For example, the researchers are designing the system to work with brain-wave detection devices that would cost less than $100."
