Evaluating the impacts of concurrency control over user experience in feature-based collaborative designing

Abstract

Collaborative CAD is the trend for the next generation of CAD systems. A concurrency control approach is the fundamental leveraging tool for resolving design conflicts. Although several algorithms are proposed, seldom study has been carried out for evaluating the correctness and user satisfaction. This paper presents an experimental study to investigate users’ satisfaction level over both pessimistic and optimistic concurrency approaches. Based on the experimental results, we also discuss propose implications for developing both concurrency control approach and collaborative designing platforms.
