High Fidelity Facial Motion Capture

High fidelity facial motion capture, or performance capture as it is someties known, is a version of facial motion capture ? monitoring the movement of the cheeks, lips, chin, nose, eyes, ears, and eyebrows of the user?s face ? in which an extremely high degree of subtlety is captured. This is used to monitor breathing, nostril flare, even the twitch of an earlobe. Everything geared to reading and interpreting even the most subtle of facial movements in real-time.

High fidelity facial motion capture is ideal for reconstructing precise sounds from lip movements, for this same reason.

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?

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.

Horses and Other Animals in Motion: 45 Classic Photographic Sequences

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.

Stop Staring: Facial Modeling and Animation Done Right

An expressive face is a work of art. Constantly moving and changing. Lips, brows, frown lines, each is in constant motion. Stop Staring analyses facial structures and movements, then shows animators how to bring life to the faces of their characters.

MoCap for Movement Analysis
Promising work by QuinteQ on real-time motion capture without excessive hardware, holds promise for MoCap use in public VR.

China's All-Seeing Eye: Sensor Web of Surveilance
China is building a high-tech police state under a massive surveillance and censorship program: "Golden Shield," linking surveillance cameras, the Internet, phones, facial-recognition software, voice recognition data from phone calls, GPS monitoring, and facial photos into a centralized database for every person in China - 1.3 billion faces.

Ishikawa Komuro Lab's high-speed robot hand
In May 2009, the Ishikawa Komuro Lab in Japan, demonstrated the capabilities that robotic manipulation of objects had reached. They had created a three-finger robot arm, with tactile sensors on its fingers, with each finger capable of independent 180 x 180 x 360 motion. All three were connected to a high-speed machine vision camera.

Electrocorticography Grows Up
Electrocorticography or ECoG is a method of neural interface in which an electrode array, quite like a fine mesh, is draped over the upper surface of the brain directly, under the skull. A section of the skull is removed to allow the array to be fed in, then replaced. The result is near-identical to a high fidelity EEG that is under the skull and thus away from its pattern dampening properties.

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.
