CELSTEC Clicker is an audience response system, also called “clicker” or “personal response system”. This system is composed by two modules, the first one is an app used for gathering questions to individuals based on their location (See figure 1 and 2), and second one, a platform for monitoring back the results of the poll to the group in the form of a chart or graph (See figure 3).
