I had a chance to go to the Shenzhen Hi-Tech Fair last week. I didn't have enough time to walk through the whole show, but I got to see some cool stuff.
3D TV
I remembered the first time I went into a 3D theater back when I was 10 or so at Disney. Though I didn't really like the short movie, it was an immersive experience. After so many years, it wasn't much of a surprise to see the technology getting applied onto televisions. The image quality was good. I did see a bit of misalignment in the video, which should be solved with a bit of adjustment. They showed it on a projector instead of a TV, but I guess they did it to give people a more immersive experience.
Smart Home
I've done a bit of research on it during university, so I know what it was about. Most of the smart technologies shown at the booth was based on the idea that you can control the lights, HVAC system, window blinds, and other electronic appliances remotely. Nothing groundbreaking, but they were the only exhibitors showing such technology.
Lasers
For some reason, I noticed a lot of exhibitors showing laser cutting and etching technologies at various scales. Though I haven't seen the machines first hand before, I've certainly seen a lot of examples of products on the market that have used the technology. It certainly does a good job at attracting people's attention.
