Providing the best Third-Person Perspective to a Video-Through HMD
نویسندگان
چکیده
This paper describes a system with several fixed cameras that provide Third-Person Perspective (3PP) to the video-through HMD of the user. Once done, our system uses an algorithm to make intelligent switches between the different cameras in order to provide the best view to the user. User comfort does not suffer from the changes of perspective; some of the users even play at forcing the perspective change during the experiment. Working with an augmented environment larger than a desktop seems to be very promising for future researches in this domain. Keywords-component; Artificial, augmented, and virtual

Intelligent switch:∗ An algorithm to provide the best third-person perspective in augmented reality
Augmented reality (AR) environments are suffering from a limited workspace. In addition, registration issues are also increased by the use of a mobile camera on the user that provides a first-person perspective (1PP). Using several fixed cameras reduces the registration issues and, depending on their location, the workspace could also be enlarged. In this case of an extended workspace, it has b...
متن کاملEffects of Visual Display on Joint Excursions Used to Play Virtual Dodgeball
BACKGROUND Virtual reality (VR) interventions hold great potential for rehabilitation as commercial systems are becoming more affordable and can be easily applied to both clinical and home settings. OBJECTIVE In this study, we sought to determine how differences in the VR display type can influence motor behavior, cognitive load, and participant engagement. METHODS Movement patterns of 17 h...
متن کاملComprehensive Tracker Based Display Calibration for Holographic Optical See-Through Head-Mounted Display
A holographic display system is able to offer an immersive 3D experience with a controllable focus cue that matches the depth information of virtual content. Proper calibration of an OST-HMD must take into account the specific features of that HMD. Existing calibration methods, however, cannot fully capture the optical characteristics of holographic display systems. With the aid of tracking sys...
متن کاملPerspective Preserving Solution for Quasi-Orthoscopic Video See-Through HMDs
In non-orthoscopic video see-through (VST) head-mounted displays (HMDs), depth perception through stereopsis is adversely affected by sources of spatial perception errors. Solutions for parallax-free and orthoscopic VST HMDs were considered to ensure proper space perception but at expenses of an increased bulkiness and weight. In this work, we present a hybrid video-optical see-through HMD the ...
