October 2009Eindhoven, the Netherlands - The Emotions Jacket is a research platform that uses the sense of touch to take the cinematic experience to new levels, allowing viewers to experience the intense emotions felt by characters on-screen. While other viewing enhancement techniques focus primarily on audio and visual aspects, the Emotions Jacket instead stimulates the biggest, our heaviest and most sensitive sense; the human skin. This exploration is part of Philips’ wider ‘sensory experiences’ program.
Over the years, there have been many developments which have
made the TV viewing experience more immersive. Examples
include surround sound, widescreen, HD (high definition) and
Philips Ambilight, which extends the picture beyond the
confines of the screen and into the room. Philips has also
introduced the Cinema 21:9 TV which is the world’s first
cinema-proportioned television. All strive to bring
cinematic scenes to life in the home. Until today, however,
the focus has been on enhancing the impact of what the
viewer sees or hears. The area of touch has remained
relatively unexplored. By applying its core competencies in
human perception and behavior, combined with its expertise
in sensors and actuator technologies, Philips is
investigating a new dimension in the immersive home cinema
The Emotions Jacket platform is a tightly fitting garment which incorporates a series of evenly-spaced actuators - based on the vibrator motors used in mobile phones - sewn into the arms and torso. By activating these actuators in response to what is happening on screen, it becomes possible to recreate certain feelings being experienced by the characters in the film. This is possible because research has shown that when people experience the physical manifestations of an emotion, they also experience the emotion itself. For example, fear sends a shiver down the spine, while excitement results in butterflies in the stomach. If you 'reverse engineer' this – i.e. you generate the shiver or the feeling in the stomach, then the associated emotion also occurs.
The result is that, when wearing the Emotions Jacket, viewers feel that they are truly part of the on-screen action, sensing for themselves the emotions experienced by the main character or others prominent in a particular scene. As Paul Lemmens, a scientist with Philips Research explains: “If you’re watching, say, a kung fu movie while wearing the Emotions Jacket, you won’t feel the physical punches and kicks, but you will experience the immense relief when the kung fu master escapes the evil henchmen.” Since touch is the only one of the five senses that is located all over the body, the viewing experience could scarcely be more immersive.

40 corrections per second2007-12-06 12:27:37 by iamlucky13
What they mean when they say that, is that the computer reads the input states 40 times per second. Each time it reads the input states, it compares the values to expected values, then uses an algorithm to determine the desired control states. We now have computers with processing power to do it hundreds of thousands of times per second...much much faster than the response times of the systems involved and sometimes faster than any actuators can actually respond.
The algorithms are engineered from known factors like lift, drag, center of gravity, etc. Then some poor schmuck of a test pilot takes the plane up and determines if the engineers got it right or if it needs a little tweaking (hopefully not a lot of tweaking)
