This article presents a set of classroom practices created for the disci‐ pline of Geomorphology that use an Augmented Reality installation known as SARndbox. This set was developed respecting the characteristics and according to a set of usability guidelines for applications that make use of Natural User Interfaces (NUI). The characteristics of Natural Interfaces, as well as the usability guidelines used in the development of these practices are presented. Keywords: Augmented reality · Classroom practices · Natural user interfaces · Usability guidelines 1 Introduction Augmented Reality (AR) applications aim to enhance the perception and effectiveness of the user by providing additional visual information. The user stays aware about the real world, but, ideally, is not able to distinguish between information coming from the real or the virtual world [1]. The use of RA systems has been investigated since the early 1990s, and includes medicine, production processes, aeronautics, robotics, entertainment, tourism, marketing, social networking and education [2]. The Augmented Reality has also benefited from several technological advances that have occurred in recent years, which have given rise to more natural and low-cost inter‐ faces and human-computer interaction devices. Among these devices, depth sensors attract attention by implementing advanced interfaces in various Augmented Reality applications, from advertising to serious games for physical rehabilitation [3–8]. The present work presents a set of classroom practices for Geomorphology based on an Augmented Reality installation, known as SARndbox [9]. This set was developed based on guidelines developed for systems that use Natural Interfaces, as well as the pedagogical needs intrinsic to the teaching practices of the topics covered. This paper is organized as follows: Sect. 2 presents some applications that use Augmented Reality in Education; In Sect. 3 the concept and characteristics of Natural User Interfaces; Sect. 4 presents the SARndbox, an installation used to support © Springer International Publishing AG 2017 M.
