A apparatus and method for detecting electromagnetic changes in the environment using electronic sensors is disclosed. The apparatus and method may be utilized in various environments including for electronic entertainment devices with interactive controls, and for interior design, lighting and illumination. The detection process consists of two stages. First, a sequence of pulses is generated with no predetermined duration at a given time interval, where the average frequency is determined by the frequency characteristics of the shaping amplifiers. This pulse sequence is converted into a sequence of numerical values and statistically analyzed. Data obtained can form the control signals for color components of light emitting devices as well as being displayed on linear scales. By adjusting the detection sensitivity, and by utilizing various embodiments of the sensor, the apparatus and method may form the basis for a range of useful products. |
