computing augmented travel

In order to have a happy, relaxing and successful trip, we need to manage a lot of information from diverse channels of resources. The process of traveling involves a lot of decision makings, attraction appreciations, and planning, all of which are very information intensive processes. The decision could be where to go, where to stay, how to transport, what to bring, what to wear, what events are interesting to attend, and etc. We need to learn the introductions of different places, find out the news such as whether a certain place is open or closed, we need to pay attention to the weather conditions, read feedbacks from other travelers, find out whether there are suitable restaurants and etc. How toursits manage to obtain all these information? How are these kinds of information supposed to flow from the sources such as the park administrations and other tourists? Who will check in information? How and where should we check out information? Usually all the information is distributed in different brochures, forms, books, websites, and etc. I want to understand the tourists' behaviors and how information technology can ease the decision making process. One important thing is that the decision making process doesn't need to be rational and should also be emotional. For example, how can information be presented that users can feel it and immediately make decisions. However, most of the information so far is textual, and with maps sometimes. For example, when I was in Yosemite last time, we wanted to hike for a while. However, which trail to take is hard to pick. The visitor center gave us a table listing all the trails, with information regarding how long the hiking will take, how to get the entrance of the trail, and what attractions are there on each trail, and how difficult the trails are. However, I need to read them, understand them, and make decisions. But if I don't know so well about those attractions, it is hard for me to make decisions. How can the information presented that we can feel how interesting the trail is? Whether augmented reality can help that situations?
