AR Digital Workspace Using a Mobile Device

In this study, to overcome the issues with the narrow display areas of mobile devices such as smartphones and tablets, we propose an Augmented Reality (AR) technology called "AR Digital Workspace" that augments a workspace in real space by superimposing windows on a plane in real space. In the proposed interface, a plane in real space is detected when a user moves a mobile device, and multiple windows are superimposed on the detected plane. By touching the screen of the device, the user can change the position and size of the windows, and copy and paste text between windows. The user can also copy text in real space using character recognition on document images acquired from the camera. This system enables users to work while displaying a large amount of information in a pseudo spacious workspace. We implemented the proposed interface on a mobile device using ARCore, an AR framework for Android devices.
