Handheld Augmented Reality Interaction Technique

Handheld devices are popular device for an Augmented Reality application. It has a basic hardware requirement for AR system. However it must be overcome some technical obstacle to realize its true power. One of the problems is interaction in handheld AR environment. Touch screen interaction is one of the common interaction methods in handheld AR but it is not easy to interact in touch screen with virtual object in handheld AR scene. Current research shows that Freeze Interaction technique shows its usefulness in handheld touch screen AR interaction. However it has a drawback such as, when users freeze their view it freezes the whole scene. When virtual object are updating continuously the real world-view is not being updated and remains as still picture. It can be a problem when users need to deal with current up-to date real world scene. To overcome current problem of Freeze Interaction technique we have implemented new freeze technique ‘Freeze-Object’ for more precise interaction. This paper presents a short review of handheld AR interaction technique and our proposed work.
