In recent years, backpacks have begun sporting outside pockets that are, not coincidentally, the perfect size for an iPod. Handbags routinely feature cell-phone compartments. And now, from practical to modem, the fashion industry is taking a cue from these gadgets, integrating their technologies into the fabrics rather than merely providing storage for them.
Known as "haute(高级定做服装) tech." these designs sometimes resemble costumes borrowed from the set of a sci-fi thriller. Like all old mood ring, one dress can sense the mood of its wearer by gauging his or her gestures and then respond with all appropriate song from its MP3-integrated hood (风帽, 兜帽). The innovations know no bounds, and can be quite funny: Erik De Nijs, a student at the Utrecht School of the Arts in the Netherlands, created a pair of tech jeans that incorporates a wireless Bluetooth keyboard into the lap of the pants. Speakers are integrated into the knees of the jeans and a mouse is conveniently stored in the hack pocket. While some might find this kind of lap typing mildly valgar, it highlights the way haute tech is pushing practical, wearable technology. Other garments use a nickel-anti-titanium (镍和钛) shape-memory alloy to move shinning panels of fabric as if they are breathing, like coral (珊瑚) shifting with the title. " Clothing becomes the interface to tell a story, "says British haute tech designer DiMainstone, au artist in residence at New York’s Eyebeam studio.
One of Mainstone’s newest projects, Sharewear, stems from the idea thin in today’s fast-paced society, time for" intimate bomey encounters" is limited. So Mainstone created a costume made up of modules inspired by icons of the home, like the armrest of a favorite sofa. In addition to looking cool, Sharewear is meant to evoke the idea that clothing serves both to shelter and to define us—just like our homes. "I wanted that esthetic of something that was very familiar." Mainstone says.
Widely credited as the founder of haute tech, British designer Hussein Chalayan-twice named British designer of the year-is the subject of a fun and fascinating new exhibit at the London Design Museum called "From Fashion and Back" (through May 17), which highlights his 15-year career. Among the items on display: a garment made of crystals and 200 moving lasers to create a living light show, and two LED—screen video dresses that illuminate underwater sea life. Chalayan believes that integrating technology with fashion is "the only way in the world to create something new," he says. "These are the prototypes for things to. come. They need this investment. /
What does Erik De Nijs integrate into the fabrics of his design according to the passage

A:A Bluetooth. B:An MP3. C:A mouse. D:Speakers.

Conceived initially by Ericsson, before being adopted by a myriad of other companies, Bluetooth is a standard for a small, cheap radio chip to be plugged into computers, printers, mobile phones, etc. A Bluetooth chip is designed to replace cables by taking the information normally carried by the cable, and transmitting it at a special frequency to a receiver Bluetooth chip, which will then give the information received to the computer, phone, whatever.
What is basic function of the original Bluetooth

A:To connect the computer and the mobile phone. B:To transmit information traditionally carried out by cables. C:To send information from one computer to another. D:To connect different webs on the Internet.
