Abstract:
1. A method of converting brainwave signals into a control signal, the method comprising the steps of: receiving a brainwave signal; generating a first value and a second value based on the received brainwave signal, wherein the first value is different from the second value; calculating a ratio between the first and second values, wherein the calculation comprises (first value−second value)/(first value+second value); comparing the ratio to a predetermined threshold, wherein the predetermined threshold is between −1 and +1; outputting a first control signal based on the comparison of the ratio to the predetermined threshold; determining whether the ratio satisfies the predetermined threshold; and increasing the predetermined threshold when it is determined that the ratio satisfies the predetermined threshold and decreasing the predetermined threshold when it is determined that the ratio does not satisfy the predetermined threshold.
