The Soapbox is a prop for political debates and protests made from an oak frame lectern fitted with a fake microphone and an iPad.
The iPad (using an app called the Votometer) records the speeches delivered from the Soapbox whilst measuring audience reaction. Those listening to the speaker are given cards green on one side and red on the other. Displaying green indicates approval to what is being said whilst showing red signals dissent.
The Votometer captures the changes in colour and displays it in real time to both the orator and the audience. The resulting ongoing poll is also logged and time stamped so that the fluctuating popularity of the speech is recorded and can be reviewed later. Audience members can also send tweets to the Soapbox which scroll across the bottom of the screen.
