Abstract: An information-processing system for market research includes a number of stations connected to the computer, each desirably having a touch screen. The program available in the computer is adapted to output a series of questions to a respondent, optionally after providing beforehand information necessary to answer a question. Once the respondent has answered the group of questions, the respondent receives a free reward, such as a gift voucher or product, for example. By presenting product information about which questions are asked, the invention ensures that each respondent has viewed the provided information before the respondent can receive their reward.
