The Hyperlinked Overview of Piloted Evaluations (HOPE) application provides an interface for users to enter data on pilots, metrics, configurations, tasks, and data collection sessions, as well as descriptive information for each item and the experiment as a whole. As this information is collected, hyperlinks allow other users (possibly without editing privilege) to peruse the database and see all runs for a given task or configuration, background information on evaluation subjects, simulation configuration, and summaries of various metrics.
HOPE is a Web-based database user interface that allows capture and analysis of subjective opinions and objective metrics for simulation-based task analysis. Typical subjective measures include flying or handling qualities and task-load estimates, along with actual objective performance measures. Links to audio, video, and transcribed pilot comments are automatically provided for an unlimited number of tasks, runs, configurations, and evaluation pilots. The entire database is linked and searchable via hyperlinks.
The database search capability is automated utilizing hyperlinks to easily access pilot simulation data. It enables authorized users to insert additional data as it is collected, and allows access and updating of the data from a central, and possibly remote, computer database utilizing the Internet.
The HOPE application is an opensource implementation that can interface with any typical database system from a range of vendors (MySQL, sqlite3, ORACLE, etc.). The tool was built using open-source development frameworks Ruby 1.8.6 and Rails 2.2.2.
