Efficient Reduction of Access Latency through Object Correlations in Virtual Environments
Object correlations are common semantic patterns in virtual environments. They can be exploited to improve the effectiveness of storage caching, prefetching, data layout, and disk scheduling. However, we have little approaches for discovering object correlations in VE to improve the performance of storage systems. Being an interactive feedback-driven paradigm, it is critical that the user recei...
متن کاملEfficient Manipulation of Object Groups in Virtual Environments
In this paper, we describe simple techniques for object group manipulation, an important operation in user interaction with a Virtual Environment. All presented manipulation techniques exploit constraints to simplify user interaction. The techniques are based on how humans perceive groups and afford direct manipulation of such groups. Furthermore, we introduce two new intuitive ways to create a...
متن کاملAccess Latency Reduction in Contemporary DRAM Memories
Performances of DRAM memories are characterized by memory latency and bandwidth. Contemporary DRAM memories more successfully satisfy demands for higher bandwidth than lower latency. In this paper solutions, which may reduce latency of these memories, are investigated. These solutions are two new controller policies called ’Write-miss Only Close-Page’ and ’Write-miss Only Close-Page-Open previo...
متن کاملLow 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 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...
