Low latency technology for interactive virtual environments
Minimizing system latency is a traditionally important topic for the development of multi-modal Virtual Environments (VE). Human perception thresholds have to be met in order to create immersive environments with a high degree of believability. The system latency has to be in the range of milliseconds, indicating the need for fast interfaces and low system overhead. This thesis provides a compr...
متن کاملHead Tracking Latency in Virtual Environments: Psychophysics and a Model
Quantification of perceptual sensitivity to latency in virtual environments (VEs) and elucidation of the mechanism by which latency is perceived is essential for development of countermeasures by VE designers. We test the hypothesis that observers use “image slip” @e., motion of the VE scene caused by system time lags) to detect the consequences of latency rather than explicitly detecting time ...
متن کاملEffect of Latency on Presence in Stressful Virtual Environments
Previous research has shown that even low end-to-end latency can have adverse effects on performance in virtual environments (VE). This paper reports on an experiment investigating the effect of latency on other metrics of VE effectiveness: physiological response, simulator sickness, and self-reported sense of presence. The VE used in the study includes two rooms: the first is normal and non-th...
متن کاملGeneralizeability of latency detection in a variety of virtual environments
User perceptual sensitivity to changes of full system latency was tested in three simple virtual environments, two with either only a foreground or a background object and an additional one that combined both types. Earlier psychophysical measurements of sensitivity (just noticeable differences) and bias (points of subjective equality) are confirmed and contrasted with other reports in which su...
متن کاملAn adaptive latency mitigation scheme for massively multiuser virtual environments
As massively multi user virtual environments (MMVEs) expand in terms of size and user population, they tend toward using P2P architectures as a way to provide scalability without the need for large centralized resources. DHT based networks have been introduced as a promising option for overlay-based distributed massively multi user virtual environment applications. However, overlay latency stre...
