"MEGAPHONE3001" is a multiplayer real-time collaborative telephony platform for use on large screens in public space such as sports arenas and concert venues, and movie theaters. It isn't a mobile application, but a phone system that users can call in to. The phone system reacts to buttons and voice to control a screen near the user. It can be used for information, advertising, and is currently setup as a series of games.

MEGAPHONE3001 is using VoIP technology to be compatible with any phone. It receives a phone call as voice over IP and it processes the key press data and voice data which can be either pitch or volume and sends it to the application running on the display.

On a technical level, if the latency between the user\'s button press and the update on the screen is too long, or users have different latency to the same screen, then realtime games can\'t be developed perfectly. But the realtime integration of button tone AND voice data combined with refined interaction design, graphics, and sound makes a user experience far above what raw code can deliver.
