Enhancing Rock Painting Tour Experience with Outdoor Augmented Reality The use of augmented reality technology is becoming a necessity of many cultural heritage sites to stay competitive and attractive to tourists. In this paper, we present an outdoor augmented reality guidance system for ancient rock painting aiming to enhance tourist experience and introduce the culture and historical background. We propose a twostage approach that combines GPS and featurebased recognition methods. In the first stage, we build a navigation map in advance, which consists of the distribution information of major scenic spots, then visit these spots guided by GPS data on the standard smartphone. In the second stage, we adopt a featurebased recognition and tracking method to identify rock painting accurately and augment them with interactive contextual annotations like 3D textual labels, images, and videos. The reliability of this system is verified through onsite demonstrations  RockArt of the Helan Mountain, which is one of National Key Historical and Cultural Sites in China.

Augmented reality for cultural heritage education In the past few years, it is noticed a fast adoption and increase of mobile devices that are able to retrieve information quickly, regardless of the userxe2x80x99s physical environment. Thus, application developers have leveraged it by developing a variety of applications using mobile Augmented Reality (AR) in domains such as cultural heritage education, shopping, gaming, and more. AR technology overlays a virtual object into the real world that enables users to have virtual and realworld experience at the same time. During a visit to a cultural heritage site such as a museum or an art gallery, the learning experience and enjoyment is necessary for a visitor and AR introduces new opportunities to improve them. We propose an ARbased framework for cultural heritage education. We aim to promote cultural heritage education by enriching userxe2x80x99s experience and at the same time to offer the knowledge with the most enjoyable way. In order to evaluate our framework, we have developed a server application and an ARbased smartphone application.
