8、ational Tourism 1. Introduction Educational tourism is one of the trends that have higher growth in recent years [1]. Tourists are beginning to give more importance to new ways of knowing different tourist destinations,

9、so the possibilities of learning grow significantly. On certain occasions, the learning activities at the destination are performed as annexed to the travel aim, but other times, the purpose of the trip is the learning

10、 itself. The most common way to know any city is through brochures provided by the Office of Information and Tourism. In this way these offices can foster a more attractive way to learn about the different aspects of t

11、he city. However, Augmented and Virtual Reality technologies can be used to improve the user experience a step further in this learning process [2]. The first one is used mainly in the travel, while with the second one i

12、s possible to recreate the tourist space elsewhere. Other novel technique for tourism is based on the utilization of * Corresponding author. E-mail address: marmar@tel.uva.es Available online at www.sciencedirect.com

15、ame engine Unity 3D [4]. The first step developing this game was the integration of the Kinect device in Unity 3D. This was done using Microsoft Kinect SDK [5] and a Unity 3D package known as Kinect Wrapper, which incl

16、udes a number of scripts and prefabs that allow the recognition of the player within the scene. Using this package you can insert a skeleton in the stage that is able to play all the moves that the player makes in fron

17、t of the Kinect device. During the game it is essential to detect the movements being made by the user: if a movement is allowed and expected, then an event in the game has to be triggered, while if the movement it is

18、unrelated to character controls, nothing should happen in order not to spoil the game proper operation. All controls are done adding Box Colliders to different parts of the user skeleton (see Fig. 3), and using OnTrigg

19、erEnter(), OnTriggerStay() and OnTriggerExit() functions in different scripts, as well as different tags. Fig. 3. Skeleton with colliders The avatar mesh was created using the open source software Make Human [6]. This c
