We describe a user study comparing a two-handed controller-based input device to a two-handed tracking solution, both offering the control space of six degrees of freedom to each hand.  ...  For benchmarking the different input modalities we implemented a set of evaluation tasks requiring viewpoint navigation, selection and object manipulation in a maze-like virtual environment.  ...  The handheld input device resembles a game controller but uses two small elastic 6-DOF sensors instead of the commonly found 2-DOF joysticks (Figure 2 ).  ...

Robust Monocular SLAM for Egocentric Videos [article]

Suvam Patra, Kartikeya Gupta, Faran Ahmad, Chetan Arora, Subhashis Banerjee
2018 arXiv   pre-print
We investigate the reported failure of state of the art (SOTA) SLAM techniques on egocentric videos.  ...  The incremental nature of SOTA SLAM, in the presence of unreliable pose and 3D estimates in egocentric videos, with no opportunities for global loop closures, generates drifts and leads to the eventual  ...  We note that the typical motion profiles of handheld videos, even if unstable, are not similar to that of egocentric videos.  ...

Analysis of Locally Coupled 3D Manipulation Mappings Based on Mobile Device Motion [article]

Paul Issartel, Tobias Isenberg
2017 arXiv   pre-print
We examine a class of techniques for 3D object manipulation on mobile devices, in which the device's physical motion is applied to 3D objects displayed on the device itself.  ...  We then investigate the effects of a limited range of manipulation and present a number of solutions to overcome this constraint.  ...  The constraint of 2-DOF input often leads to complex and unnatural 3D manipulation techniques.  ...
