Delegates had relevant apps installed on their phones to ensure they could make the most of the event, which showcased a wide range of other technology, including 3D body scanners, holographic projection and digital imagery.
Gareth Dimelow, executive director of experience planning at George P Johnson, said that simple technologies, such as smartphone microphones, could make the biggest difference at events.
"This particular piece of technology allows delegates to use their smartphone as a microphone - which is much easier than using a roving mic," he explained. "Smart apps are great in the industry because it means we can use technology we’re already familiar with whilst utilising new ideas to help us deliver our strategic goals."
Mike Walker, managing director of MGN Events and another conference attendee, said that smartphone apps were a cost-effective way of improving audience participation and involvement: "It’s vital for events to find new ways to hold people’s attention and smartphone apps are a cheap way for companies to do this. You just download the app and tailor it to your needs."
