Recently, IDM performed a survey asking manufacturers what they think will be the big technology in the coming years. This year, the survey revealed that most manufacturers think that holographic video calls will be the big thing between now and 2015. This technology has already been experimented with and includes a pico projector to display holograms. The survey included over 3000 people from various manufacturers. Some of the other ideas that were suggested include batteries that were powered by air, computers crunching numbers for real-time traffic information, and heat-generation for homes, from computers and data centers.
