3D mobile interactions for public displays

Abstract

Public displays are becoming common in public spaces like bus stops, movie theatres and work places. Getting and maintaining the user attention is one of the main struggles of public displays [Müller, et al, 2010]. Therefore there is a need to investigate public display interactions to propose interactions that can help engage users with the public display more. In this paper we choose to investigate collaboration as a way to improve user engagement with public displays based in previous results where creating a shared experience for an audience made the participants engaged with the activity [Scheible and Ojala, 2005]. We proposed the use of 3D user interfaces to give users tools to collaborate with other users, because controllers that allow for natural movements have the potential to offer greater affordances for social interaction [Lindley, et al, 2008]. In order to solve users privacy concerns we utilize mobile interactions, where a mobile screen can be used to display private and personalized information. In the proposed 3D mobile interaction we utilize the mobile device screen to augment 3D content on the public display utilizing an Augmented Reality (AR) tracking approach. We propose that having 3D content gives public displays a new layer of depth for collaboration between users. With this new layer users can create novel interactions where they not only consider the content on the public display but also the position of the users around it.
