Intuitive & Precise Interaction in Handheld AR

Some of my recent research focused on developing novel methods to intuitively interact with 3D content in a handheld augmented reality scenario. In such a scenario, the user usually has only one hand available for interaction that limits the possibility to apply complex finger gestures for precise selection and 3D object manipulation.

DrillSample: Precise Selection in Dense Handheld AR Environments

We introduce a novel selection technique DrillSample, which allow for accurate selection in a one-handed dense handheld AR environments. It requires only single touch input for selection and preserves the full original spatial context of the selected objects. This allows for disambiguating and selection of strongly occluded objects or of objects with high similarity in visual appearance.  








3DTouch & HOMER-S: Intuitive Manipulation for One-Handed Handheld AR

We introduce two novel, intuitive six degree-of-freedom (6DOF) manipulation techniques, 3DTouch and HOMER-S that provide full 3D transformations of a virtual object in a one-handed handheld augmented reality scene. While 3DTouch uses only very simple touch gestures and decomposes the degrees of freedom, Homer-S provides integral 6DOF transformations and is decoupled from screen input to overcome physical limitations.

ARTiFICe

Augmented Reality Framework for Distributed Collaboration

This project aims on developing a flexible and powerful VR/AR framework build around on an off the shelf game engine (Unity3D). It offers rapid prototyping to create distributed and collaborative virtual and augmented reality applications. Its flexible design allows the rapid integration of new hardware, software features as well as 3D interaction techniques. It can be used in fully immersive setups with 6DOF interaction devices and HMDs, semi-immersive enviroments with stereo projector walls, desktop setups as well as mobile environments. ARTiFiCe is currently used for our research and teaching purposes at Vienna University of Technlogy.
