A RESTFUL service for aggregating state-based user performance data in simulator scenarios

Simulators often implement their own solution for aggregating and saving user performance data. Aggregating user performance data from simulators that execute on many different machines can be a pain for researchers and the data is often saved in one format that can be hard to translate to others. A framework is proposed to provide re-usable scenario initialization and user performance data aggregation functionality to simulators. A RESTful web service is proposed to aggregate and store the user performance data in the cloud for later retrieval for analysis and evaluation. Two simulator clients built with Unity3D are developed for validation of the web service. Preliminary results show that the web service offers good performance and data integrity, but is still a work in progress.
