Guidelines for Graphical User Interface Design in Mobile Augmented Reality Applications

The technological advancement of mobile devices allowed the entry of innovative technologies in users’ daily lives, due to miniaturization and advancement of sensors, cameras and computer resources. These technologies make it possible to increase the user’s interaction and perception about places and objects around him, allowing, for example, the use of augmented reality. However, this opportunity presents new challenges, such as application design and development, aspects to this new context of ubiquitous devices, heterogeneity of mobile devices, and how the user interacts with these applications. Thus, this paper aims to present the results of Mobile Augmented Reality application usability evaluation, identifying a list of problems in the application Graphical User Interface and propose some guidelines for building Graphical User Interfaces to avoid these problems. The chosen usability evaluation is the Think Aloud protocol, which was performed with 20 participants in the Mobile Augmented Reality application named ARguide.
