Description
本发明属于互联网领域，尤其是涉及一种根据目的导航的方法以及导航系统。 The invention belongs to the field of Internet, and in particular relates to a method for navigating according to purpose and a navigation system.
手机已从以前含有打电话、发短信等几个简单功能的功能机时代，发展到了现在给人们生活带来无数便利的智能机时代。智能手机强大的操作系统给人们带来更多、更强、更具个性的社交化服务，在娱乐、商务、时讯及服务等应用功能上能更好的满足消费者对移动互联的体验，它几乎成了这个时代不可或缺的代表配置。
The mobile phone has evolved from the era of functional machines that used to have several simple functions such as making calls and texting, to the era of intelligent machines that bring countless conveniences to people's lives. The powerful operating system of smart phones brings more, stronger and more personalized social services to people, and can better satisfy consumers' experience of mobile internet in entertainment, business, news and services. It has almost become an indispensable representative configuration of this era.
因此，手机GPS定位和导航现在是智能手机不可或缺的重要功能，手机导航就是通过 手机
的导航功能，把你从目前所在的地方带到另一个你想要到达的地方，它能够告诉你在地图中所在的位置，以及你要去的那个地方在地图中的位置，并且能够在你所在位置和目的地之间选择最佳路线，并在行进过程中的为你提示左转还是右转。手机导航不用额外开支买导航，升级地图方便，很便携，可以在饭桌上就预先设计好接下来的行程路线或是可以在走路的时候导航。 Therefore, mobile phone GPS positioning and navigation is now an indispensable function of smart phones, mobile phone navigation is through mobile phones
The navigation function takes you from where you are from to where you want to go. It tells you where you are on the map, where you are going, where you are going, and where you can Choose the best route between your location and your destination, and give you a left or right turn during the journey. Mobile navigation does not require extra cost to buy navigation, upgrade maps are convenient, very portable, you can pre-design the next itinerary at the dinner table or you can navigate while walking.
但是，我们在使用导航时，经常会遇到这种情况：用户开车到某地，可能对当地只有大概印象，和大概目的，而无具体的目的。如，用户到云南师范大学校本部请人吃饭，用户对云南师范大学周边不是很了解，在这种情况下，用户不知道具体有些什么餐馆，应该请朋友去哪个餐馆吃饭就是个问题。因此，用户一般要么在去之前会用手机搜索了解，要么到达地点后再用手机寻找临时决定，总之，都是需要用户自己通过互联网去搜索，操作繁琐而且费时，用户体验不佳。
However, when we use navigation, we often encounter this situation: users driving to a certain place may have only a general impression of the local, and probably the purpose, but no specific purpose. For example, the user went to the school headquarters of Yunnan Normal University to invite people to eat. The user is not very familiar with the surrounding of Yunnan Normal University. In this case, the user does not know what kind of restaurant is specific. It is a problem to ask a friend to go to which restaurant to eat. Therefore, the user generally searches for it by mobile phone before going there, or uses the mobile phone to find a temporary decision after arriving at the location. In short, the user needs to search through the Internet by himself, the operation is cumbersome and time consuming, and the user experience is not good.
综上，针对于当前用户在使用导航到达目的地时，还需要自己动手搜索与用户自己目的相关的地点，这种用户体验不佳的情况，需要提供一种在导航时能够推荐与用户目的有关的地点的方法。
In summary, when the current user uses the navigation to reach the destination, he or she also needs to search for the location related to the user's own purpose. If the user experience is not good, it is necessary to provide a recommendation related to the user's purpose during navigation. The method of the location.
本发明实施例提供了一种根据目的导航的方法，目的在于针对于当前用户在使用导航到达目的地时，还需要自己动手搜索与用户自己目的相关的地点，这种用户体验不佳的情况，需要提供一种能够推荐与用户目的有关的地点的导航方法。
