This study is to utilize consumers' 'consciousness' about products using brain reactions. In particular, the nerves of elderly consumers, which are physically functionally dull, can grasp the interests, preferences, and emotions of elderly consumers who respond to stimuli such as hearing, touch, and smell. Based on this information, the name, design, and performance of the product can be used to help provide customized products using brain response technology. Neuromarketing increases efficiency in a variety of areas. Color, image, and design ads that can awaken consciousness can help develop ads that can affect more effective message delivery and memory by analyzing consumers' brain responses and applying them to advertising strategies.
