Virtual tours, they are a good use of sending knowledge and experiences over the internet. A virtual tour is a simulation of a place around the world that allow you to experience: pictures, videos and much more. While the tour is going it will give you information of the place you are visiting.The highlights of virtual tours are that they are very accessible on the internet, they give you high definition pictures and give you important information to the specific topic you are touring. My opinion on virtual tours are that they are an awesome use of knowledge to people that would like to visit other countries but haven't got the money to, though with every project there are flaws. Some problems with tours are that they can be outdated, really slow and you don't get the feeling of being there. A great site for virtual tours is
http://www.youvisit.com/ . It has a wide variety of places you can explore for example hotels, restaurants, travel destinations, real estates, businesses and events and venues.The site makes you feel you are there at that exact moment. Another bonus is that there is a voice recording that speaks to you and gives you plenty of useful knowledge.
