Abstract: In an information providing system, a transmitter/receiver of an information providing device serves as a relay station to allow wireless data transmission and reception between the information providing device and a tablet and between the information providing device and each of response clickers provided for individual responders in audience. The information providing device wirelessly receives data from the tablet and from each individual response clicker in a specified time interval of data transmission after transmission of a transmission approval. The information providing device transmits the transmission approval to a transmitter/receiver of the tablet at a higher frequency than a frequency of transmitting the transmission approval to a transmitter/receiver of each of the response clickers. This effectively increases accumulation of the time interval of data transmission from the tablet to the information providing device.

Abstract: An information providing system is configured to provide each of students with an image of a material taken with a camera of an information providing device and allow interaction with the student. The teacher operates a tablet to set a plurality of answer options as available response choices for a question, such that the number of answer options is equal to or less than the number of answer buttons provided on each response clicker. The response clicker receives answer options specification data for specifying the answer options set by the teacher and provides initial notification that notifies each of the students of the answer buttons respectively corresponding to the plurality of answer options specified by the received answer options specification data.
