Can you imagine surfing the Internet without lifting your finger? Do you want to know what it feels like to fly like a bird? Let’s have a look at some of the “Best inventions of the Year 2012”.
Wing Suits
The suit can make your dream of flying like a bird come true. Well, not exactly flying, but gliding（滑翔）through the air. Fliers wearing wing suits can glide one kilometer in about 30 seconds. But they need a parachute（降落伞）to make a safe landing because the suit does not allow you to slow down.
Talk Gloves
Do you often feel confused（困惑的）by the sign language used by disabled people? Here is the “helping hand” you need. Four students in Ukrainian college have invented a pair of gloves that helps people who has hearing and speech problems to communicate with others. The gloves are set with sensors（传感器）that receive sign language and translate it into text on a smart phone. Then the smart phone changes the text to spoken.
Google Glasses
In short, Google Glasses are like a computer which is built into a pair of glasses. The glasses allow you to surf the Internet and make phone calls without even lifting a finger. All you have to do is to let your head move the mouse on the screen. The glasses also have a camera and GPS mapping system. Users can take and share photos, video-chat, check maps and surf the Internet just by looking up, down, left and right. But now they are on sale only in two countries, German and America.
