How 3-D Gestures Works ??

How do you redefine a user interface? What steps do you need to take to change the way people interact with technology? It's not just a matter of developing the right tools.

Can you hack a drone?

We live in an age of hackers. Whether it's yanking payment and credit card information from large retailers, pilfering personnel information from the U.S. government or snatching a treasure trove of juicy emails, salary information and unreleased films from Sony Pictures, the black hats are out there and they're trying to get in.

We also experience the passage of time, a fourth dimension. Beyond that, we only know other dimensions are even possible through theoretical mathematics. Our universe may hold secrets that we will never be able to observe directly.

Even if you discount string theory and the idea of dimensions beyond our perception, our world contains a wealth of information that most of us aren't aware of in our daily lives. When visiting a city for the first time, for example, we may only have our senses to rely on when gathering information. A smartphone or computer can help out, pulling in more data about the city's geography, history, economics, cuisine and other cultural features.
