Abstract
Nowadays, handheld devices are capable of displaying augmented environments in which virtual content overlaps reality. To interact with these environments it is necessary to use a manipulation technique. The objective of a manipulation technique is to define how the input data modify the properties of the virtual objects. Current devices have multi-touch screens that can serve as input. Additionally, the position and rotation of the device can also be used as input creating both an opportunity and a design challenge. In this paper we compared three manipulation techniques which namely employ multi-touch, device position and a combination of both. A user evaluation on a docking task revealed that combining multi-touch and device movement yields the best task completion time and efficiency. Nevertheless, using only the device movement and orientation is more intuitive and performs worse only in large rotations.
