Problems solved by technology

[0003] This ideal setup does not exist outside of the lab, making these systems unusable to reliably measure a user's brain waves in a non-lab environment
Also, special treatment of the head to use laboratory electrodes is not practical in a non-laboratory setting

Embodiment Construction

[0022] The apparatus and method are particularly applicable to systems for controlling toys using a user's brainwaves and it is in this context that the apparatus and method are described below for illustrative purposes. However, it should be understood that the apparatus and method may be used in applications other than controlling toys, and indeed in any application where it is desired to quantitatively assess a user's brainwaves and provide a human-machine interface and / or neurofeedback based on the quantitative assessment of the brainwaves used in . For example, the apparatus and method can be used to control a computer or computer system, a game console, and the like. As another example, the apparatus and method could be implemented and integrated into a pilot's helmet that has a brainwave monitoring system built into it, where dry sensors can monitor the pilot's brainwaves during flight, and if the pilot is flying During loss of consciousness, the device can detect the ...

Abstract

A noise-free portable EEG system is provided. The system has hardware and software and can evaluate mental state quantitatively. The quantitative data of mental states and their levels can be appliedto various areas of brain-machine interface including consumer products, video game, toys, military and aerospace as well as biofeedback or neurofeedback.

Description

technical field [0001] The field generally relates to devices and methods for quantitative assessment of mental state. Background technique [0002] There are many methods available for detecting brain waves and using them as control signals as well as diagnostic tools. However, many obstacles to measuring brain waves without noise remain, especially outside of well-controlled laboratory settings. Brainwaves are generally detected and utilized in laboratories where the environment and electromagnetic noise are strictly controlled, and the only static condition for the patient or subject whose brainwaves are being measured is that the patient or subject should not move. This ideal setup does not exist outside of the laboratory, making these systems unusable to reliably measure a user's brain waves. In addition, typical sensor arrangements require special handling of the head, since most currently used electrodes for measuring brain waves require gel-impregnated electrodes o...
