[EX Q]: Article: Do you have a hobby--something you really enjoy doing in your spare time? Have you ever wondered what it would be like if you could spend more time on your hobby and less time at work? Maybe it's not an either/or situation. Perhaps you can do both at the same time. When choosing a career, one of the things you must consider is your interests. Why then do so many people not even think about their hobbies when a hobby is, in fact, an interest? Perhaps it's because even Webster's Dictionary defines a hobby as "a pursuit (,) outside one's regular occupation ". Maybe this is a rule you should break. After all, no one ever said your hobby had to stay separate from your occupation. In addition people are usually very skilled at their hobbies. The combination of interest and skill is a very compelling reason to choose a particular career. "Who's going to hire someone who loves making beaded jewelry?" you may ask yourself. Good question. Don't wait for someone to hire you. Start your own business. That may be the best way to combine your hobby with your career. Those with hobbies that involve creating things, i.e. jewelry, clothing, or pottery, may do well to sell those items on their own. Before you go forward with your plans, though, you should find out whether being an entrepreneur is for you. When you attempt to turn your hobby into a career, don't forget to do your homework. Even though you may have enjoyed training your pet birds to sing the national song, that doesn't mean you're suitable to be an animal trainer. Be sure to research your career choice completely. There may be aspects of it that just aren't for you. In that case, stick to your day job, as they say, and save your hobby for your free time.

[EX Q]: Article: In the near future,we may be using our eyes to operate our smart-phones and tablets,even when it comes to playing popular games like Fruit Ninja. The Gaze Group has been developing eye-controlled computer technology for nearly 20 years.But those devices have been firstly designed to help those with disabilities,and are very expensive. "After a while,we figured out that probably the best way is to go for a mass-market way," says Gaze's Sune Alstrup Johansen."where everybody would have this available." Johansen and some of his colleagues have formed a new company,the Eye Tribe,which is hoping to develop the technology on a mass commercial level. The technology works with the help of the computing device toward the user's face. After making sure of the user's eye movements,the technology is then able to easily find where a person's eyes are moving,and then allow the eyes to control a cursor . "Our software can then determine the location of the eyes and know where you're looking on the screen to make sure what you're looking at,"reads an explanation on the Eye Tribe site. There has been a gradual change toward hands-free technology in recent years, particularly in the gaming world.Recently Xbox released the Kinect device,which lets users control their Xbox and play certain games using only their hands,legs and voices. But still,most of these devices have been more of a _ than a practical way to use one's hands to control a mobile device.Johansen said a replaceable filter would be a cheap,convenient way for most consumers. And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.
