Q131.
How are stereoscopic images generated in VR systems?

a.

By using multiple screens for each eye

b.

By adjusting the positions and angles of the virtual objects

c.

By creating perspective distortion in the images

d.

By using occlusion effects to enhance depth perception

Discuss
Answer: (b).By adjusting the positions and angles of the virtual objects Explanation:Stereoscopic images in VR systems are generated by adjusting the positions and angles of the virtual objects to match the typical distance between the eyes on a human face.
Q132.
What is one method of delivering stereoscopic images?

a.

Using small screens fitted to goggles

b.

Using inverted binoculars

c.

Using virtual reality helmets

d.

Using holographic displays

Discuss
Answer: (a).Using small screens fitted to goggles Explanation:One method of delivering stereoscopic images is by using small screens fitted to goggles. Each eye sees a different image displayed on these screens.
Q133.
What is a current trend in the development of stereoscopic displays?

a.

Increasing the size and weight of the devices

b.

Encasing the user's head in a helmet-like device

c.

Reducing the size and weight towards ordinary spectacles

d.

Enhancing the image quality using OLED technology

Discuss
Answer: (c).Reducing the size and weight towards ordinary spectacles Explanation:A current trend in the development of stereoscopic displays is to reduce the size and weight of the devices towards the size and weight of ordinary spectacles. Smaller and lighter LCDs are enabling the development of more compact and lightweight stereoscopic display devices.
Q134.
What are some alternative methods for delivering stereoscopic images?

a.

Using timed electrical signals to blank out each eye

b.

Using polarized filters and lenses in spectacles

c.

Using red-green 3D spectacles

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Alternative methods for delivering stereoscopic images include using timed electrical signals to blank out each eye, polarized filters and lenses in spectacles, and red-green 3D spectacles.
Q135.
How do the techniques using polarized and blanked eye spectacles compare to red-green spectacles?

a.

They provide a substantially better quality 3D image.

b.

They are less effective in creating a 3D effect.

c.

They have wider viewing angles.

d.

They are commonly used in wide-scale 3D television broadcasts.

Discuss
Answer: (a).They provide a substantially better quality 3D image. Explanation:The techniques using polarized and blanked eye spectacles provide a substantially better quality 3D image compared to red-green spectacles. They are more advanced and offer improved viewing experiences.
Q136.
What is one challenge in achieving the ideal 3D viewing experience?

a.

Narrow viewing angles of screens with vertical grooves

b.

Low horizontal resolution of stereo images

c.

Lack of focus adjustment for each eye

d.

Incompatibility with holographic technology

Discuss
Answer: (c).Lack of focus adjustment for each eye Explanation:One challenge in achieving the ideal 3D viewing experience is the lack of focus adjustment for each eye. Our eyes naturally focus on the current object of interest, but stereoscopic images are generated at a fixed focus, which can be confusing and tiring for viewers.
Q137.
What is a method for adjusting the images based on the focal depth of each eye?

a.

Using holographic technology

b.

Inscribing the screen with small vertical grooves

c.

Applying laser technology for eye tracking

d.

Using polarized filters in front of the screen

Discuss
Answer: (c).Applying laser technology for eye tracking Explanation:One method for adjusting the images based on the focal depth of each eye is using laser technology similar to eye tracking. This method detects the focal depth of each eye and adjusts the images accordingly.
Q138.
How extensively is the use of lasers for adjusting focal depth currently implemented?

a.

Widely used in 3D television broadcasts

b.

Commonly used in family viewing settings

c.

Not used extensively at the moment

d.

Rapidly gaining popularity in the industry

Discuss
Answer: (c).Not used extensively at the moment Explanation:The use of lasers for adjusting focal depth based on eye detection is not currently implemented extensively. Although progress has been made, it is not widely used at present.
Q139.
What is a limitation of screens with small vertical grooves?

a.

Narrow viewing angles

b.

Low image quality

c.

Insufficient resolution for stereo images

d.

Lack of compatibility with eye tracking technology

Discuss
Answer: (a).Narrow viewing angles Explanation:Screens with small vertical grooves have the limitation of narrow viewing angles. While they allow for stereo images, they are not suitable for family viewing due to their limited viewing angles.
Q140.
Why is display performance important in VR systems?

a.

It affects the quality of the visuals

b.

It can cause disorientation and motion sickness

c.

It determines the level of immersion in the virtual world

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:Display performance is important in VR systems because it affects the quality of the visuals, can cause disorientation and motion sickness if there is a lag between head movement and scene changes, and determines the level of immersion in the virtual world.
