The trend:
Mobile phones, when first introduced, were so big that they almost resembled a lunch box. The cell phone underwent a large number of changes and became more presentable. They became more colorful, sleek and smaller in size. With fashion becoming a very important part of the day to day life, mobile phones are becoming much trendier and are now available as wearable products. Mobile phones are now available as watches, bracelets, necklaces and what not. These trendy and fashionable mobile phones are soon going to hit the market. Nokia is the first company to introduce its first wearable phone e.g. Nokia’s first wearable phone Nokia Medallion is designed to carry, wear and display images which reflect the personality of the user and finally act as an necklace or a bracelet. With the Nokia Kaleidoscope I a user can upload digital images and easily store and carry them. To become a leader in any kind of business every company needs to think out of the box and also design products according to the customer needs. So these wearable mobile phones are designed to stand apart from the crowd.

The inspiration:
Pranav Mistry from the MIT Media Lab. has developed the wearable internet connected computer. This computer can turn virtually any physical surface, be it wall, hand or even a hand book into a Microsoft surface like able computer. It allows interacting with that surface using hand-free gestures. With this device, Google maps can be displayed on the walls and can be easily zoomed and panned using fingers. It also helps display ratings of books and other things using. The pictures and videos can be displayed on the wall of a room and can be easily arranged using natural hand gestures only.

What makes it so special?
Evolution is the law of nature. This also holds true for mobile industry. Nowadays mobiles can be used as fashion accessories. It is like wearing mobile phones as a necklace or a bracelet. Mobile phone is now a thing that is to be flaunted rather than hiding it in pocket or a bag. Ring tones are no more a disturbance to other people because a mobile that is worn on the wrist can be easily kept on the vibration mode and can be peacefully used. It can also be used at noisy places by putting a microphone and speaker very close to the ear and the mouth. The hand can be used in doing other useful work like writing. Because the electromagnetic field is very far away from the head, the fear of electro smog is also wiped off. Because the microphone and speaker are separated, the phone can be adjusted according to the personal shape of human cranium. The touch screen is equipped with voice activated and hands-free software so it can dial and pick up and also hang up the line. And also it is fun to use.
What's in it for me?
MIT media lab has developed a gesture controlled wearable computing device that gives the user relevant information and turns any surface into interactive display. It works on certain gestures and on object recognition. The sixth sense aims to integrate information and technology into everyday life. It is a simple web cam and portable battery powered projector with a small mirror that are fashioned into a pendant style necklace which communicates with the cell phone. In this a hand can be used as a keypad for calling call up a map or to arrange the pictures and the videos. Emailing can be done by simple gesturing and also for getting flight updates. It is also possible to get product information and check time by simply drawing a circle on your wrist.
