Interaction methods for mobile augmented reality
Huidong Bai, Gun Lee · 2012
In recent years mobile phone based Augmented Reality (AR) has become very popular. The current generation of smart phones has cameras, GPS and compass sensors, and significant CPU and GPU power, making them idea for mobile AR applications. Interaction concepts for handheld mobile AR often focus on device-centric interaction methods based around the screen touch. However, users may not be able to easily interact with virtual objects in mobile AR scenes if they are holding the handheld device with one hand and touching it with the other, while trying to maintain visual tracking of an AR marker. In this demonstration we show two novel interaction methods for handheld mobile AR; (1) freeze view touch and (2) zooming interaction. Freeze view touch allows people to manipulate virtual content on a frozen view of the AR scene, while zooming interaction uses an automatic zooming method to allow people to easily manipulate virtual content without the need to move close to it.
