ARWand: Phone-based 3D Object Manipulation in Augmented Reality Environment

Abstract

In this paper, we suggest a mobile phone-based indirect 3D object manipulation method that uses sensor information in an augmented reality environment. Specifically, we propose 1) a method that exploits a 2D touch screen, a 3DOF accelerometer, and compass sensors information to manipulate 3D objects in 3D space, 2) design transfer functions to map the control space of mobile phones to an augmented reality (AR) display space, and 3) confirm the feasibility of the transfer functions by implementation. Our work could be applicable to the design and implementation of a future mobile phone-based 3D user interface for AR application in normal indoor and outdoor environments without any special tracking installations.

A Pilot Study on Stepwise 6-DoF Manipulation of Virtual 3D Objects using Smartphone in Wearable Augmented Reality Environment

Abstract

- In general, 6 degrees of freedom (DoF) manipulation of 3D virtual objects requires cumbersome external tracking installations to localize and track the input device in a normal wearable augmented reality (WAR) environment. In this paper, a smartphone-based 6-DoF manipulation method is proposed to avoid the use of complicated installations. First, the proposed 6-DoF manipulation method (3-DoF translation and 3-DoF rotation) exploits various embedded sensor information of the smartphone. Transfer functions are then designed to transfer the phone’s 6-DoF control gain to the 3D display space’s object manipulation gain. According to the experimental results, the quadratic transfer function was superior to the linear and acceleration functions with less completion time and errors.
