all out to ensure their passengers have the best possible flight experience.now，europes low-budget airline，easyjet，wants to extend the positive experience beyond the plane ride with “sneakairs”smart shoes that allow visitors to explore new cities and towns without ever looking at a map.to transform sneakairs from an ordinary shoe to a tour guide，all the wearer has to do is enter his or her desired destination into the easyjet smartphone app.a built-in gps will determine the wearers starting location while the google maps navigation(导航) tool will help chart the best route.whenever a change of direction is necessary，the app will communicate with the appropriate shoe via the bluetooth and cause it to vibrate(振动).for example，if the wearer needs to turn right，he/she will feel the sensation in the right shoe.if the user misses the turn，the smart shoes will both vibrate at the same time，reminding him/her to change course.visitors who wander off the suggested path or decide to take a break for a cup of coffee or a meal have nothing to worry about.the smart app will automatically determine the new location and chart out a new route. once the desired destination is reached，sneakairs will vibrate three times to inform the user of the arrival and then go back to being ordinary shoesuntil their navigation services are needed again!sneakairs is certainly not the first navigation shoe in the market.however，easyjet is the first airline to offer them to passengers just as they are about to land in an unknown city.however，before sneakairs can go mainstream，the easyjet team still needs to make some adjustments.among the challenges that need to be addressed is the smart shoes three-hour battery life，which is hardly enough for a tourist to catch all the delights a new city or town has to offer!语篇解读本文介绍了航空公司easyjet发布的一款名为sneakairs的智能运动鞋，它能够为用户选择、规划路线，以帮助用户在陌生的城市尽情游玩。1.the airline easyjet designed sneakairs in order to.a.help people exercise with
