LectureHall

What it is:
LectureHall enables a lecturer or conference presenter to track the reception of his/her messages by the audience. It could also be used as a simple polling mechanism.

How it works:
You start by entering the name and description for your lecture or presentation. Then you create some questions under it.
You may then start a lecture session and broadcast the session code to the audience.
Using this app, your audience register in your session and response to your questions interactively.
During the presentation you may post a question at any time, which will appear on the mobile phones or tablets of your audience. As the audience is responding to your question, you are able to monitor the results directly on your own mobile or tablet.
