Audience feedback n It was just like I was watching it at the Olympic Stadium. n I felt as if I understood what the realistic sensation is for the first time. n The impact was great that I could almost smell and feel the fireworks at the opening ceremony. n Felt like the person behind me was clapping. n Could see the natural 3D image. n Could clearly see the person who threw a bottle at Bolt. n Want to believe this is the first step to the next generation TV. n Blurring with pan shot is bothering. n Image is very clear but it needs a large screen size and is questionable whether it fits to home viewing. 38
