Why does environment protective product need survey to enquire design questions?In conclusion, environment protective product researchers are similar to design product researchers who can use interviews and questionnaires to measure consumer response to their both products? They have similar point, such as environment protective products and general products which need to be designed. If the design of environment protective product is very attractive to compare other environment protective product competitors. Then, its sale numbers have possible to be increased. Hence, face to face walking interview and questionnaires with pedestrians is one kind of consumer behavior prediction method.In psychology view point, implications tests have been developed in an attempt to overcome and to obtain investigates the adaptation of implicit methods to measure how to design product preference. Two questions are for test. (I ) establishing an acceptable methodology for tests using environment protection product images . (ii) determining whether response to design environment protection products can produce significant effects in affective experiments. How can environment protection design researchers predict how to design their environment protectionproduct to be more attractive? Understanding how environment protection consumers experience to design environment protection products have important implications for environment protection design research and design practice. These questions are often investigated experimentally by presenting consumers with a range of environment protection products or design variants and measuring subjective response for future design development. Measuring environment protection consumer response to design environment protection product testing, e.g. survey methods, questionnaires, interviews and focus groups. Questionnaire methods are especially popular, and often feature attitude response, such as choice questions. Although, those explicit measures can provide helpful feedback to environment protection product designers, who are also subject to a number of limitations. Consumer survey responses to a product or predict future environment protection behavior, such as how to design environment protection product purchasing decisions in the environment protection marketplace. In some cases, environment protection participants might be motivated to answer a questionnaire dishonestly, or in a way that seems most socially acceptable. However, the survey may not be targeting the same thought processes that a consumer faces in the environment protection product use scenario or in the environment protection marketplace. There is evidence that actual environment protection product-related behavior is affected by more spontaneous or processes, as consumers are often distracted or pressed for time when consuming actual environment protection products or making purchasing decisions. Other methods include psychophysiological techniques, such as eye tracking, brain imaging, heart rate measurement, and voice pitch analysis for an overview of these methods applied to design environment production product measuring to consumer responses.
