Application Event Control Module for SAGE

SAGE has received attention as a middleware that allows scientists who use large-scale data to control and drive a Tiled Display, which provides high-quality and high-density visualization with multiple displays. However, SAGE has a problem of poor application operability. This problem is due to the architectural design of SAGE that users have to manage window-related operation and application-related operation from different interfaces. To address this problem, we have developed an application event control module for SAGE. This module unifies the two separated interfaces of window management and application operation. Our design principle is to minimize the current SAGE architecture changes and keep portability of the module. In this paper, we describe the function, design and implementation of our module. To evaluate interactivity and operability of our module, we measured time taken from coming up an event to the completion of event reaching an application and time taken for users to perform pointing operation through SAGE UI. As a result, we confirmed that our module provides realistic interactivity and allows users to smoothly perform pointing operations.
