Understanding 3D Vision and Technology

What is the primary advantage of using two eyes for vision?

• It provides a backup in case one eye fails.

• It enables stereoscopic vision, offering depth perception.

• It allows for a wider field of view.

• It helps in color differentiation.

What was unique about Bruce Bridgeman's experience with the movie 'Hugo'?

• He saw a 3D movie for the first time.

• He developed stereoscopic vision after watching it.

• He found the movie boring.

• He realized he had a lazy eye.

Why do some people not develop stereoscopic vision?

• Due to poor nutrition.

• Due to genetic factors.

• Because of a lack of exposure to 3D images in childhood.

• Because they have a lazy eye or are cross-eyed.

What is motion parallax?

• A depth perception cue where background moves less than the foreground.

• A technique used in 3D movies to create depth.

• A way to stabilize images in motion.

• A method to enhance color perception.

How do glasses-less 3D TVs create a 3D effect?

• By using polarized glasses.

• By projecting holograms.

• By alternating strips of images with a barrier.

• By using motion sensors.

What is a major limitation of current 3D movie technology?

• It can only be viewed from a specific angle.

• It is only available in black and white.

• It lacks motion parallax.

• It requires special glasses.

What is the role of polarizing filters in 3D glasses?

• To reduce screen glare.

• To send the correct image to each eye.

• To block harmful UV rays.

• To enhance color contrast.

What makes holograms different from other 3D technologies?

• They are only available in red light.

• They are cheaper to produce.

• They require no special glasses.

• They offer true depth perception and parallax.

What is a common flaw of holograms?

• They are not visible in daylight.

• They must be illuminated with one color of light.

• They require a specific viewing angle.

• They are not truly 3D.

What is the future potential of holographic video?

• To replace all 2D films.

• To be available only in museums.

• To be used only in scientific research.

• To offer full-color, true 3D experiences.
