Qus:1 With the help of block diagram
explain Convolvotron.
Answer: Once a user’s HRTF is
experimentally determined, it is possible to take any sound, apply the pinnal
transforms as finite impulse response (FIR) filters, and play back the sound to
the same user over a headset. The user then has the sensation of hearing that
sound as coming from a
Qus:2 Explain
haptic feedback and sensing.
Answer: The last category of I/O devices
discussed in this unit is haptic interfaces. Named after the Greek term hapthai
(meaning “touch”), they convey important sensorial information that helps users
achieve
Qus:3 Write short notes on:
• multiple pipeline synchronization.
• distributed VR engine
Answer: •
multiple pipeline synchronization
Whether multiple
Qus:4 Explain the first stage of
haptic rendering.
Answer: The first stage of haptic rendering
(and thus physical modeling) is collision detection which determines whether
two (or more) objects are in contact with each other. This can be
Qus:5 Expalin the process of
automatic cell segmentation.
Answer: This process partitions the
virtual world into smaller universes, or cells. Only objects within the current
universe are rendered, thus reducing complexity significantly. This approach is
illustrated in Figure. This segmentation method is ideal for architectural modeling
of large buildings (rather than a single auditorium). In this case most of the
model does not contribute at
Qus:6 What are the advantages of
stereopsis?
Answer: With complex images it has been
found that subjects could easily use stereopsis to enhance 3-D spatial
judgments when monocular depth cues were ambiguous. Depth cues additively
interact with each other to get more vivid 3-D representation. Stereopsis
appears to be a compelling
