SERVICE PROVIDING SYSTEM
First Claim
1. A service providing system comprising:
- an output section for presenting a question to a user, and further presenting sequentially a plurality of options as candidate answers to the question;
a signal detection section for measuring an event-related potential of electroencephalograms of the user;
a determination section for determining whether the user has thought each option to be a correct answer or not, based on the event-related potential in a predetermined period after each option is presented;
a database storing a plurality of questions as well as options which are correct answers to the plurality of questions and options which are not the correct answers; and
a selection section for, when there is one option which is determined by the determination section to have been thought to be the correct answer by the user and the option is described as a correct answer option in the database, selecting a question of a genre different from that of the question presented by the output section.
