METHODOLOGY

According to In the Interactive Learning Modules project, we are developing interactive simulation games using multimedia software in the areas of design and manufacturing, the use of multimedia tools to create an environment which simulates an integrated view of a product development process.

The primary layer of the display hierarchy is a set of modules which represent the basic functional units of the project. The four types of modules currently included: (a) simulation, (b) handbooks, (c) case studies, and (d) utilities

a) Simulated role environments where the user may be dynamically interacting, choosing parameters, making decisions, or defining configurations of objects and sequences of events on the screen.

b) Handbook environments where the user is searching for background information and principles in order to support the simulated role.

c) Case study environments in which the user is watching and listening to presentations of real case studies related to the problem being solved. Our current Case studies include animation, video, audio, and 3D (QuickTime VR) presentations of materials.

d) The utility modules incorporate global models and behaviors, and support standard displays. [1, 4].

These display modules and activities interact with the content modules which represent the subject matter of simulations, tutorials, and case studies. Product parts such as electronic components or factory machines can be accessed as design topics, graphic displays, or video displays.

A multimedia environment provides a setting for creation of simulation experiences structured as challenging interactive games. Multimedia software development often entails two conflicting goals.

First the content of the application material must be developed in a structured and reliable software environment. In the case of a simulation or game, the content portion encompasses the data, logic, and computation of the underlying materials. Second the display of the media itself and the associated interactivity requires manipulation of display elements and support for interaction.

The control flow and interaction within such a program is constrained to establish structured procedures or object-oriented protocols in order to sustain reliable development, maintainability, and reusability of code. On the other hand, the interactive navigation required for a flexible user environment often encourages control flow which creates entertaining but unverifiable paths, leading to reliability and deadlock problems in the resulting software. Advantages using the Cybertronic Games Interactive Design tools:

Modules for functional and physical design of electronic circuit boards, and for layout and planning of electronics manufacturing activities are being developed.

Multimedia case studies: Case studies of product development, management, and manufacturing are being developed to explain and analyze the principles which affect manufacturing decisions. An electronics manufacturing line is designed to bring the factory to the user, and incorporates principles of design, fabrication, assembly, solder, and test.

Interactive simulation modules: Integrated simulation takes special advantage of the multimedia environment and involves the user in the decision making and design processes associated with the manufacturing and marketing processes. Video of a real factory is combined with simulation and animation to study the choice of manufacturing systems and the scheduling of activities.

Interactive tutorial units: Handbooks and libraries are accessed to provide necessary background to understand the technical and managerial issues associated with specific manufacturing domains.
