Mobicon lets you engage audience in a lecture. Lecturer can prepare quizes and polls at home and then activate them during lecture. Audience then using their smartphones votes/answers -> results are shown on a graph which is "live" updated.
Also, everybody is present in big "chatroom", so audience can ask questions without interrupting lecturer.
And what's the best - they can use their smartphone as a microphone to talk!
It is a way to get real time feedback during lecture, both from audience and lecturer.
It is a web/mobile application with great UX and sleek design.
