ELECTROENCEPHALOGRAPHIC AUDITORY AND VISUAL STIMULUS ATTENTION MONITOR

摘要

ABSTRACT A method and apparatus for determining the level of attention of subject for both auditory and visual stimulus such as television commercial displayed on screen, billboards, radio advertisements, checking the product response at designing stage to ensure products market potential, response to the price of the product or service, campaigning or the likes. This method provides the objective information which will help in designing the product, advertisement presentation, pricing for the companies™ products or services, campaigning or the likes. The technique involves projecting audible and visible radiations from monitor screen or VR- goggles and headsets at a predetermined frequency. This control signal is first applied to subjects and an EEG response is obtained. The control signal is then simultaneously applied with audio and visual information, television commercial, design of product, price of product or services or the likes, and EEG signals are obtained. An assessment of the subject™s interest is then made by determining the increase or decrease in the value of the components of the EEG response attributable to the control signal. A pair of headsets (audio device) along with VR- goggles is also disclosed.
