Motion Capture

Motion Capture or MoCap, is a technique used to digitally record precise body movements.

There are several different methods of MoCap. Most involve markers of some type or another stuck to the user?s body, tracking the relative positions of each part of the head, torso, and the limbs. A few more recent methods simply use machine vision, although the accuracy is not as high.

Only the physical movements are recorded, and placed onto an avatar which duplicates the movement precisely. No appearance information is taken, making MoCap perfect not just for films, and animation pre-rendering, but as a form of replacing a physical form with a superior virtual one, as well.

Horses and other Animals in Motion is a collection of, as the title says, 45 sets of photographs of horses hauling, walking, trotting, etc., plus sequences of donkeys, an ox, pig, dog, cat, deer and other animals capture details of anatomy and movement. These images, were taken by the definitive expert in the field, Eadweard Muybridge.

Video games need 'realism boost'
BBC article about how to add authenticity to VR, goes beyond graphics, also encompassing extensive use of motion capture to catalogue how stance, gait and the tiny movements of facial muscles combine when people display different emotions.

Combining MoCap and Gesture Recognition
MoCap - Motion Capture - for all its impressive abilities, has definite limitations in terms of sensory fidelity, the expense and bulk of the rig. Gesture control is cheap and captures every little movement, but easily overwhelmed. Is a hybrid system possible?

Cheapening the Cost of Motion Sensors
Motion sensors are starting to creep into a whole plethora of applications. They are the linch pins of haptics, of 3D pointers, of stress based sensor networks and locomotive VR interfaces. Yet, there's a problem. Small, discrete motion sensors, tiny enough to be built into larger devices the size say, of a Wii-remote or a 6 ounce HMD, are extremely difficult and expensive to produce.

Eadweard Muybridge's pioneering work on the motion of all manner of quadrupeds. Horses, goats, cats, gnus, eagles, gazelles, sloths, camels, many others shown walking, running, flying, leaping, almost a complete range of natural motions duplicated for the benefit of animators and skeletal model making.

The paperback 'lightweight version of 'The Human Figure in Motion', this book as might be extrapolated from the title, contains 60 photographic sequences of the more common everyday activities of both men and women. Most are nude, allowing the musculature and natural drooping from one frame to another to be clearly seen and analysed.

After photographer Eadweard Muybridge created his revolutionary photographs of animals in motion in the late 1890s, he turned his attention to the study of the human form, by taking detailed photographs in rapid succession step by step as the human body underwent all manner of daily activities. These photographs have served for over a century, as the most highly acclaimed reference point for animators.
