⦁Comparative Benefits / Advantages Face reading technology can help only confectionery eating food manufacturers to measure sugar element whether how much sugar weights are the most suitable to young people taste acceptable level more absolutely. Digital camera and computer recording technology can predict whether what factors can influence the consumer to choose to buy your competitor's similar product or your products and measure whose satisfactory level to let manufacturer to judge how to manufacture whose products of features are more suitable to be acceptable or attractive to consumers' taste. If the confectionery eating food manufacturer could not detect consumers' emotion to know whether what level of sugar ingradient is the most suitable level to cause who are like or dislike to eat or drink confectionery foods from whose face expression absolutely. It will be serious loss to invest time and money to manufacture this foods and consumers will feel their foods or soft drinks is not health to eat to cause illness possibly. Traditional sensory and consumption tests predict consumer acceptance of new food products rather poorly, as are evidenced by the high their failure rates in the market. These tests typical reflect conscious processes whereas consumer acceptance may also be based on unconscious processes. For example, I feel functional (MFR) isn't an allowable technology space primarily due to consumer concern of manipulation. Miller (2012) indicated that '' functional MRI mind reading technology is where something is wholly subjective and private, and it can't be predict consumer emotion to tell from what who're doing or looking at, what whose mental state is." Hence, It has a distinction between that kind of mind reading and what is brain reading, which essentially involves using brain scans to figure out what the factors can influence on consumer's mind in different situations to decide buy or not buy the food product. So, any consumer emotion researcher needs to wait a few seconds to see what consumers will do next. The technology is still limited, such as individual differences: Different consumers' brains code information sight differently, so consumer emotion researcher needs to learn how a specific individual codes consumers' emotion mental states. How to produce the most acceptable sugar level to manufacture any confectionery eating food or drink for children, it can keep consumers who will choose to buy other brands of confectionery eating food or drink more easily. This is the most important factor to influence your children taste choice to feel your brand confectionery eating food or drink is the best taste to compare other brand competitors. So, sugar ingradient ( element) of the acceptable level is the most important research from face reading technology experiment in shop or factory.
