Rohit Pandey, Pavel Pidlypenskyi, Shuoran Yang, Christine Kaeser-Chen
2018 Lecture Notes in Computer Science  
We tackle the problem of efficient 6-DoF tracking of a handheld controller from egocentric camera perspectives.  ...  Our proposed SSD-AF-Stereo3D model achieves a mean average error of 33.5 millimeters in 3D keypoint prediction and is used in conjunction with an IMU sensor on the controller to enable 6-DoF tracking.  ...  An approach to automatically label 6-DoF poses of handheld objects in camera space. 2. The HMD Controller dataset 1 , the largest-to-date markerless object 6-DoF dataset.  ...

Andre Kunert, Alexander Kulik, Anke Huckauf, Bernd Froehlich
2007 ICAT-EGVE 2014 - International Conference on Artificial Reality and Telexistence and Eurographics Symposium on Virtual Environments  
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.  ...  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 tracking-based input we use two handles each containing an electromagnetic 6-DOF sensor (Figure 1 ).  ...

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.  ...  Another interpretation is that the object is stationary whereas the viewpoint is moved in an opposite way. This type of transformation is called egocentric.  ...

Robust Monocular SLAM for Egocentric Videos [article]

Suvam Patra, Kartikeya Gupta, Faran Ahmad, Chetan Arora, Subhashis Banerjee
2018 arXiv   pre-print
Taking inspiration from batch mode Structure from Motion (SFM) techniques, we propose to solve SLAM as an SFM problem over the sliding temporal windows. This makes the problem well constrained.  ...  We investigate the reported failure of state of the art (SOTA) SLAM techniques on egocentric videos.  ...  Acknowledgement: This work was supported by a research grant from Continental Automotive Components (India) Pvt.

The design-by-adaptation approach to universal access: learning from videogame technology

Ifan D. H. Shepherd, Iestyn D. Bleasdale-Shepherd
2010 Universal Access in the Information Society  
This paper proposes an alternative approach to the design of universally accessible interfaces to that provided by formal design frameworks applied ab initio to the development of new software.  ...  One of the motivations behind the current study is that VGE technology lags some way behind videogame technology in the modelling of 3D environments, and has a less-developed track record in providing  ...  Acknowledgements We wish to thank conference participants who provided comments on an original version of this paper, which was presented at the International Conference on Virtual Geographic Environments  ...

We also found a positive transfer of training from VR to stationary displays and a negative transfer of training from stationary displays to VR.  ...  Because VR interfaces are difficult and expensive to build, the computer graphics community needs to be able to predict which applications will benefit from VR.  ...  Desktop users controlled their viewpoint with the handheld "camera" controller shown in Figure 4 , which contained the same 6DOF tracker used to track the VR users' heads.  ...

Finally, we present the results of an experimental study, where we evaluate the usability, performance, and error rate of the proposed and existing 3D interaction techniques.  ...  Furthermore, because the user's finger covers a large area of the screen, the smallest size of the object users can touch is limited.  ...  Threedimensional user interfaces (UI) and applications such as shared virtual environments offer the possibility of utilizing the small display area of a mobile device in an efficient manner.  ...
