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. ...

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 ). ...

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. ...
