Army-NASA aircrew/aircraft integration program (A3I) software detailed design document, phase 3

The capabilities and design approach of the MIDAS (Man-machine Integration Design and Analysis System) computer-aided engineering (CAE) workstation under development by the Army-NASA Aircrew/Aircraft Integration Program is detailed. This workstation uses graphic, symbolic, and numeric prototyping tools and human performance models as part of an integrated design/analysis environment for crewstation human engineering. Developed incrementally, the requirements and design for Phase 3 (Dec. 1987 to Jun. 1989) are described. Software tools/models developed or significantly modified during this phase included: an interactive 3-D graphic cockpit design editor; multiple-perspective graphic views to observe simulation scenarios; symbolic methods to model the mission decomposition, equipment functions, pilot tasking and loading, as well as control the simulation; a 3-D dynamic anthropometric model; an intermachine communications package; and a training assessment component. These components were successfully used during Phase 3 to demonstrate the complex interactions and human engineering findings involved with a proposed cockpit communications design change in a simulated AH-64A Apache helicopter/mission that maps to empirical data from a similar study and AH-1 Cobra flight test

Dynamic Interactions for Network Visualization and Simulation

Most network visualization suites do not interact with a simulator, as it executes. Nor do they provide an effective user interface that includes multiple visualization functions. The subject of this research is to improve the network visualization presented in the previous research [5] adding these capabilities to the framework. The previous network visualization did not have the capability of altering specific visualization characteristics, especially when detailed observations needed to be made for a small part of a large network. Searching for a network event in this topology might cause large delays leading to lower quality user interface. In addition to shortfalls in handling complex network events, [5] did not provide dynamic user interactions since it did not have real-time interaction with a simulator. These shortfalls motivate the development of a new network visualization framework design that provides a more robust user interface, network observation tools and an interaction with the simulator. Our research presents the design, development and implementation of this new network visualization framework to enhance network scenarios and provide interaction with NS-2, as it executes. From the interface design perspective, this research presents a prototype design to ease the implementation process of the framework. The visualization functions such as clustering, filtering, labeling and color coding help accessing network objects and events, supporting four tabs consisting of buttons, menus, and sliders. The new network visualization framework design gives the ability to handle the inherent complexity of large networks, allowing the user to interact with the current display of the framework, alter visualization parameters and control the network through the visualization. In our application, multiple visualizations are linked to NS-2 to build execution scenarios which let to test clustering, filtering, labeling functionalities on separate visualization screens, as NS-2 progresses

Object oriented design of petri net simulator

Petri nets are highly useful for modeling discrete event dynamic systems. The objective of this effort is to develop a tool for drawing, editing and simulating Petri nets using object oriented programming on a standard platform. The object oriented approach was chosen because of its code reuse and extendability features which simplify the task of adding features to the tool as the model evolves. The design stresses on modeling of the problem by objects which closely relate the system design with the implementation. C++ is used for implementing the object oriented design, and the XView toolkit is used for building the graphical editor in compliance with AT&T\u27s OPENLOOK standards on a Sun Sparc IPX running SunOS 4.1.2. The object oriented paradigm was successfully applied to develop a user friendly, graphical editor and a simulator for Petri nets

Function-Based Computer Aided Conceptual Design Support Tool

Conceptual design is considered as the most critical and important phase of design process. It is the stage where product’s fundamental features are determined, large proportion of the lifecycle cost of the product is committed, and other major decisions are made, which have significant impact on the downstream design and related manufacturing processes. It is a knowledge intensive process where diverse knowledge and several years of experience are put together to design quality and cost effective products. Unfortunately, computer support systems for this phase are lagging behind compared to the currently available commercial computer aided design (CAD) tools for the later stage of design to reduce the designers workload and product development time. The overall goal of this research is to provide designers with computational tool that support conceptual design process. To achieve this goal a methodology that integrates systematic design approach with knowledge-based system is proposed in this thesis. Accordingly, a framework of computer based computational tool known as conceptual design support tool (CDST) is developed using the proposed methodology. The tool assists designers in performing functional modeling by providing standard vocabularies of functions in the form of function library, generate concepts stored in the database from previous designs, display the generated concepts on the morphology chart, combine the concepts and evaluate the concepts variants. Concepts from subsea processing equipment design have been collected and saved in the database. The tool also accepts new concepts from the designer through its knowledge acquisition system to be saved in the database for future use. In doing so, it is possible to integrate human creativity with data handling capabilities of computers to perform conceptual design more efficiently than solely manual design. The tool can also be used as a knowledge management system to preserve expert’s knowledge and train novice designers. The applicability of the proposed methodology and developed tool is illustrated and validated by using a case study and validation test conducted by independent evaluators

User Interface Design For Higher Education Usage

User interface is a part of computer and its software that people (user) see, hear, touch or talk to. It is a setof all things that allow you and your computer to communicate with each other. Agood interface design is crucial to make a software/application/system a success. In this project the author concentrate on development of user interface design for higher educational usage, specifically UTP e-iearning system interface. This project being develop to overcome several problems face by user such as making lots of frequent errors due to misunderstanding or confusion, not using or realize some of feature or functions, and inappropriate user interface or interaction. The objectives of the project are to develop a good interface design for e-learning system for intuitive usage, create a didactic environment and also to design interface that require minimal page-through to completetask(s). The methodology of the project requires several steps which are planning where preliminary investigation on the project area and project scheduling are performed, analysing where analysis being perform to understand the existing system interface function, data collection; to gather information on user preference and interface development, designing and testing that involve user acceptance testing. The result and discussion will be analysing of the previous questionnaire that had been distributed to the user in order to get the user requirements and expectation towards the new interface developed. Beside there the author also perform analysis in the design area where the author stated a few assumptions made thatwill contribute top thedevelopment of the new interfaces

Tilt and Multitouch Input for Tablet Play of Real-Time Strategy Games

We are studying the use of tilt-enabled handheld touchscreen devices as an interface for top-down strategy games. We will explore how using different input modes (tilt and touch) compare for certain tasks in terms of efficiency and comfort. Real-time and turn-based strategy games are a popular form of electronic gaming, though these games currently have only minor representation on tablets. This genre of game requires both a wide variety of input and the display of a wealth of information. We are exploring whether, with suitable interface developments, this genre can become as accessible on tablet devices as on traditional computers. These interface approaches may also prove useful for expanding the presence of other game genres in the mobile space
