Q1. What is Motion Capture. Why do we use it? why do we use it in education industry + video example required?

Motion capture is the process of tracking and recording the motion of face and body. Then, this process which is become data is inputted into computer. The digital character can exactly follow the original movement according to data.

Motion capture is cheaper, faster, easier than key-frame-based animation. Meanwhile, motion capture can effectively deal with a great amount of complex data, and making movement of digital character more realistic.

Motion capture is a good tool for education. We can use it to help students get a better understanding of bio mechanics and ergonomics. Making a better content for education.



Q2. What is the purpose of a Zoetrope + video example?
It consists of a cylinder with slits cut vertically in the sides. Some different images are on inside cylinder. We can see like animation through slits when the cylinder is spinning.





Q3.What is Rotoscoping + video example?

Rotoscoping is an animation technique in which animators trace over live-action film movement, frame by frame, for use in animated films.[1]Originally, pre-recorded live-action film images were projected onto a frosted glass panel and re-drawn by an animator. This projection equipment is called a rotoscope, although this device has been replaced by computers in recent years. In the visual effects industry, the term rotoscoping refers to the technique of manually creating a matte for an element on a live-action plate so it may be composited over another background.


Q4. Choose 1 suits, and talk about:

How does the suit work

3-5 advantages of using this suit

3-5 disadvantages of using this suit.

+ video example?

The technology of inertial suits is based on miniature inertial sensors, biomechanical models and sensor fusion algorithms. The information of insertial sensors is imputed into computer by wirelessly, which is recorded and checked.The motion data of the inertial sensors (inertial guidance system) is often transmitted wirelessly to a computer, where the motion is recorded or viewed. Most inertial systems use gyroscopes to measure rotational rates. These rotations are translated to a skeleton in the software. Much like optical markers, the more gyros the more natural the data.No external cameras, emitters or markers are needed for relative motions. Inertial mocap systems capture the full six degrees of freedom body motion of a human in real-time.

Advantages:

the quick and easy set up resulting in a fast pipeline.

portability,

large capture areas.

Disadvantages:

lower positional accuracy and positional drift which can compound over time.
