International Telemetering Conference Proceedings / October 30-November 02, 1989 / Town & Country Hotel & Convention Center, San Diego, California / Generalized telemetry data analysis systems have been developed to meet the future requirements for the analysis of telemetry data. By providing the user the freedom of stipulating the manner in which data is to be analyzed, the need for mission specific analysis software can be greatly reduced or eliminated entirely. Communications between the user and the software is accomplished by means of a user-software interface. Proper design of the interface will promote successful user-software communications. Interface design features such as menus and online documentation are discussed. Human engineering is an integral part of a successful user-software interface design. The human beings which operate the software possess limitations on their mental abilities and perception. Human engineering concepts which utilize display techniques and reference names are discussed. A definition of a successful user-software interface is given.

The main aim of this paper is to analyse the user interface of current school information system and to redesign new interface based on user testing results. The assumption for reaching this goal is the necessary knowledge of principles of designing modern user interfaces. The benefit consists in creating a whole new structure of navigation system and in the redesigning layouts. The beginning part of this work presents value of usability user interface and who is designing and testing it. The following part describes principles of modern user interfaces. Conclusion part of this paper presents a case study, which describes the problems of current user interface of the ISIS and the new solution of user interface ISIS and its navigation system.

To promote both quality and economy in the production of applications and their interactive interfaces, it is desirable to delay their mutual binding. The later the binding, the more separable the interface from its application. An ideally separated interface can factor tasks from a range of applications, can provide a level of independence from hardware I/O devices, and can be responsive to end-user requirements. Current interface systems base their separation on two different abstractions. In linguistic architectures, for example User Interface Management Systems in the Seeheim model, the dialogue or syntax of interaction is abstracted in a separate notation. In agent architectures like Toolkits, interactive devices, at various levels of complexity, are abstracted into a class or call hierarchy. This Thesis identifies an essential feature of the popular notion of direct manipulation: directness requires that the same object be used both for output and input. In practice this compromises the separation of both dialogue and devices. In addition, dialogue cannot usefully be abstracted from its application functionality, while device abstraction reduces the designer's expressive control by binding presentation style to application semantics. This Thesis proposes an alternative separation, based on the abstraction of the medium of interaction, together with a dedicated user agent which allows direct manipulation of the medium. This interactive medium is called the surface. The Thesis proposes two new models for the surface, the first of which has been implemented as Presenter, the second of which is an ideal design permitting document quality interfaces. The major contribution of the Thesis is a precise specification of an architecture (UMA), whereby a separated surface can preserve directness without binding in application semantics, and at the same time an application can express its semantics on the surface without needing to manage all the details of interaction. Thus UMA partitions interaction into Surface Interaction, and deep interaction. Surface Interaction factors a large portion of the task of maintaining a highly manipulable interface, and brings the roles of user and application designer closer.

When it comes to simulator training, there are two main target groups, the student and the teacher/instructor. This thesis will cover usability aspects for both of these groups when it comes to tasks related to simulator training. For the student it will mainly be about how they can interact with the interface from the simulator and how results and feedback from exercises are presented to them. For the teacher/instructor on the other hand, usability aspects for managing the students and the exercises will be addressed, along with how results and progress shall be presented in a way that is easy to grasp and understand. A redesign of the current system used to manage these issues will be preformed. Some of the aspects that the redesign will cover are usability aspects, graphical design and workflow. One of the main outcomes from this thesis is a system that supports many different levels of engagement from the user, allowing users with different background and interest to interact with the system as effortless as possible/wanted.
