  • Patent number: 5983129
    Abstract: A method for determining an individual's intensity of focused attention, comprising the steps of: obtaining a representative frontal lobe brainwave signal from at least one first sensor in an electrically connective relation to the individual's frontal lobe; obtaining a representative reference signal from at least one second sensor in an electrically connective relation to a more electrically-neutral location; subtracting the representative reference signal from the representative frontal lobe brainwave signal to produce a difference frontal lobe brainwave signal, and processing the difference frontal lobe brainwave signal to produce an Attention Indicator signal indicative of the individual's intensity of focused attention, where the Attention Indicator signal is inversely proportional to any mathematical transformation of an amplitude measure of the difference frontal lobe brainwave signal; inputting the Attention Indicator signal to a device; and, repeating these steps, as desired.

  • Patent number: 5740812
    Abstract: The present invention relates to an apparatus for and a method of providing brainwave biofeedback to a user while the user is simultaneously doing other tasks, for example, while the user is responding to a computer learning lab, working with another computer program, or playing a game. For example, a user could wear a headphone sensor unit, a virtual reality headset sensor unit, or a similar enclosure incorporating sensors made of comfortable compound sponges soaked in an electrolyte solution. The unit can detect brainwave signals which are then processed and interfaced with a computer. Audio and/or video feedback is provided to the user which indicates the user's focus or alertness. While the sensor unit could have therapeutic uses, the current embodiments relate to educational and recreational uses and for uses related to increasing personal performance.
