Anonymous Live Feedback of the audience, to understand or comprehend that which is presently being taught, helps both the lecturer and the listener:

• The lecturer can spontaneously react to reported shortcomings in his/her presentation, for example, when a part of the audience can no longer follow what´s being taught, due to the use of technical terms or abbreviations that have not been not explained or understood.

• The individual in the audience can immediately see how many of the present listeners are also having difficulty in following the lecture. Each person can use their smartphone for observing the Live Feedback and for commenting on their understanding and the pace of the current lecture.
