New systems for glasses-free 3D movie theater technology

The video discusses different methods of 3D viewing, including the use of projectors and polarized glasses. It highlights the limitations of some 3D TVs that do not require glasses but have a limited number of viewers. Researchers at Seoul National University are exploring two systems for glasses-free 3D movie theaters, using one projector and multiple screens to achieve the 3D effect for multiple viewers.

What is required for viewers when using two projectors for 3D viewing?

• Multiple screens

• A single projector

• No glasses at all

• Special polarized glasses

What is a limitation of some 3D TVs that do not require glasses?

• They use two projectors

• They require polarized glasses

• They have a limited number of viewers

• They are more expensive

Which university is conducting research on glasses-free 3D movie theaters?

• Tokyo University

• Stanford University

• Seoul National University

• Harvard University

What is the key feature of the systems being researched for glasses-free 3D theaters?

• They use one projector and multiple screens

• They are limited to a few viewers

• They use two projectors

• They require polarized glasses

How do the methods being researched produce the 3D effect?

• By using a series of different screens

• By limiting the number of viewers

• By using polarized glasses

• By using two projectors
