The SwRI developed GOSE system provides an interactive virtual environment to learn and practice complex procedures and an authoring environment to quickly generate GOSE simulations.

The GOSE Player application is launched from a Sharable Content Object (SCO) executing in a web browser. CLICK IMAGE FOR LARGER VIEW.

The Generalized Operations Simulation Environment (GOSE) System developed by Southwest Research Institute provides a rapid authoring environment and delivery system for developing and deploying immersive learning environments. Students use the interactive GOSE Player to learn and practice complex procedures in an interactive virtual environment. Course developers, with little or no programming experience, use the extensible XML-based GOSE scripting language and integrated authoring environment to quickly and interactively generate GOSE Simulations.

GOSE Player

The GOSE Player provides the runtime interface through which students interact with various objects, tools, and devices while navigating through a virtual environment to complete specified training objectives.

Benefits of the GOSE System

• Multiple training modes support learning and assessment of complex procedures in a realistic simulated environment.

• Supports increased retention through virtual
  hands-on training.

• Safety is emphasized by prompting students to use proper safety gear.

• Actions in one part of the simulation may later impact other parts of the environment/scenario.

• Students learn problem solving skills through the consequences of their actions.

• Students receive immediate feedback regarding learning objective progress.

Features of the GOSE System

Key features of the GOSE System include:

• Lessons and associated objectives are defined using a custom scripting language.

• Scriptable onscreen prompts guide student actions.

• Questions to test users’ knowledge.

• Students use a combination of simulated test equipment and hand tools to complete objectives.

• Simulated devices may be used to trigger predefined events and/or measure and display data in the virtual environment.

• Students access resources from a tool bag that includes various items organized into categories such as:

  • Devices

  • Tools

  • Cables

  • Hardware

  • Safety equipment

• Students interact and respond to 3D avatars that represent simulated personnel/clients.

• Online job guide provides access to relevant documentation that assists students in completing tasks.

• Student performance and progress may be stored and tracked in a Learning Management System (LMS) using SCORM 2004.

• Various motion models and predefined “jump-to” locations allow students to quickly navigate through the virtual environment.

• Multiple input devices are supported, including:

  • Standard keyboard and mouse

  • Gamepad

  • Immersive virtual reality devices

• Students determine order in which to complete portions of overall task.

  • Free play is supported

• Insets are used to display interactive models that can be viewed regardless of where the user moves in the environment.

• Students receive a summary of scoring parameters including:

  • Required score to pass

  • Actual score

  • Pass/fail

  • List of correct objectives and incorrect objectives

GOSE Simulation Builder

GOSE simulations use a custom scripting language to define learning objectives, virtual environment, and display prompts and questions. CLICK IMAGE FOR LARGER VIEW.

The GOSE Simulation Builder provides the interactive authoring environment that allows course developers to develop GOSE simulations using a custom scripting language to define learning objectives, display 3D objects in the virtual environment, and display prompts and questions.

Benefits of GOSE Simulation Builder

• Point-and-click interface to the underlying GOSE scripting language greatly simplifies training development.

• User-friendly interface provides a means for creating/editing GOSE XML script files and for organizing media content.

• Interactive controls allow playback of the simulation at any point during development.

• Interactive 3D view facilitates placement and movement of objects in the 3D scene.

Key Features of GOSE Simulation Builder

• Interactive script tree editor:

  • Supports sequencing of required tasks/objectives

  • Supports definition of associated:

    • Prompts

    • Scoring metrics

    • Feedback

• Development process is accelerated by:

  • Cut command

  • Copy command

  • Delete command

  • Disable command

• Lessons are assembled using a variety of media formats including:

  • 3D models

  • Images

  • Videos

  • Sounds

  • Flash® simulations

  • Text

• Interactive script tree display and playback controls facilitate the execution/preview of a lesson as it is created or modified.

• Interactive 3D view allows course developer to make changes to the script and continue playback.

• Conditional statements can be inserted into the lesson script, causing the simulation to branch and/or triggering events based on user actions.

• Insertion of jump-to locations or zoomable hotspots simplify navigation through virtual environment.

• Properties Editor allows the developer to quickly define properties of objects selected in the script tree editor or 3D view.

• Developers can add and organize documents such as:

  • Job aids

  • Technical orders

• By selecting from a library of reusable objects, the following can be added:

  • Environments

  • Object models

  • Tools

  • Devices

• Physics-based simulations can be added to a lesson as customizable components in the scripting language.

• Configurable tool bag allows developers to organize items for quick location and application, such as:

  • Devices

  • Hardware

  • Safety equipment

  • Tools

  • Cables

• Once a media item is created, it can be imported into the GOSE content library for use in other simulations.

• SCORM packaging interface facilitates the assembly of a simulation into a SCO for use with an LMS.

SwRI-developed Generalized Operations Simulation Environment (GOSE) uses virtual reality interfaces to enhance training effectiveness.

Initial efforts provided a desktop system in which students interact with a virtual F-15E aircraft using a keyboard and mouse.

A similar approach was used to extend the life of a legacy trainer by allowing trainees to work within the confines of a physical cockpit.

GOSE is enabling immersive desktop simulations to replace traditional classroom training situations.

Immersive Approach to GOSE

A more immersive version of GOSE supports natural interactions through the use of head mounted displays (HMD) and data glove or stereoscopic projection systems. Motion tracking and gesture recognition allow trainees to naturally view and manipulate components.

GOSE Applications

GOSE has been used to develop and deliver a variety of training applications. Initial efforts provided a desktop system in which students interact with a virtual F-15E aircraft using a keyboard and mouse. Students progress through a series of lessons, which familiarize them with the aircraft and then test their ability to identify and manipulate various aircraft components in preparation for aircraft maintenance. Instructor-defined audio and visual cues guide the students' actions. Results are scored to facilitate student progression through the training curriculum.

GOSE was further extended to provide A-10C maintenance training using an immersive approach to extend the life of a legacy trainer. Computer-generated images, displayed on an HMD, are overlaid on a legacy cockpit allowing trainees to view and interact with updated aircraft configurations without costly hardware updates.

GOSE supported a large-scale conversion of traditional classroom training to immersive desktop simulations for a major telecommunications company. The web-based simulations support a full range of technical training for installation and repair technicians. These simulations allow students to practice real-world tasks, such as:

• Performing daily inspections

• Interacting with clients

• Installing, configuring and testing voice and data networks using a variety of simulated software applications, test equipment, and hand tools
