“…For this, there have been studies that enhance immersion by enabling users to directly touch and control virtual objects by using data input glove and to feel tactility through sensors [13][14][15][16]. Moreover, a motion platform or mechanical machineries such as exoskeletons were used to make the virtual space liberally move without spatial limitation by analyzing user's joint information or detecting movement as in motion capture device [2,[17][18][19]. As the problem of spatial limitation was resolved, physical props became important factor that recreates virtual space.…”

This study proposes a modeling method that can effectively generate multiple diverse digital trees for creating immersive virtual landscape based on virtual reality and an optimization method for real-time rendering. The proposed method simplifies a process of procedures from growth of tree models to the generation of the three-dimensional branch geometric model. Here, the procedural branch graph (PBG) algorithm is proposed, which simultaneously and effectively generates diverse trees that have a similar branch pattern. Moreover, the optimization method is designed in a polygon-based branch model which controls the resolution of tree models according to the distance from the camera to generate a tree model structure that is appropriate for an immersive system based on virtual reality. Finally, a virtual reality system is established based on the Oculus SDK (Software Development Kit) and Unity3D engine. In this process, the image processing-based pixel to tree (PTT) method is proposed as a technique for easily and efficiently generating a virtual landscape by allocating multiple trees on terrain. An immersive virtual landscape that has a stereoscopic perception and spatial impression is created through the proposed method and whether it can deliver experience of nature in virtual reality to the users was checked through an experiment.

“…A lot of the work of Steinicke et al also includes the integration of physical objects to deliver passive haptics to virtual objects within the IVE (Steinicke et al, 2008b,e,f,g,d,c;Bruder et al, 2009), while they refer amongst others to (Insko, 2001;Insko et al, 2001;Kohli et al, 2005;Lindeman, 1999;Tachi et al, 1994).…”

I present an experiment to identify detection thresholds for acoustic redirected walking by means of a wave eld synthesis system. 39 blindfolded test subjects performed 2777 constant stimulus trials with rotation and curvature gains of di erent severity. The detection thresholds were greatly dependent on the knowledge the subjects had of the experiment. The most representative test group noticed an up-scaling rotation of 5% and a down-scaling rotation of 37.5%, and a circular path with a radius of 5.71 meters 25% of the time. Almost no signs of simulator sickness could be observed with the simulator sickness questionnaire by Kennedy et.
