International Telemetering Conference Proceedings / October 26-29, 1992 / Town and Country Hotel and Convention Center, San Diego, California / The design and development of user interfaces for telemetry data processing systems is undergoing a period of rapid change. The migration to graphics workstations is raising expectations and redefining requirements for user interfaces in the nineties. User interfaces which present data in crude tabular form on alphanumeric terminals are on a path to extinction. Modem telemetry user interfaces are hosted on graphics workstations rich with power and software tools. This paper summarizes the evolution of user interfaces for telemetry systems developed by Computer Sciences Corporation, highlighting key enhancements and use of third-party software. The benefits of prototyping and the trend toward programmable interface behavior are explored.

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.

<p>In Alzheimer association’s clinique practice, there was a need to communicate with people with mild dementia. Videophone is considered as one of the best assistive communication tool for these people since video communication is not only a tool to break an isolation caused by the disease, but also a powerful way to help people demonstrate their ideas and understand what is said in a conversation with pictures, signs and body language.

In Alzheimer association’s clinique practice, there was a need to communicate with people with mild dementia. Videophone is considered as one of the best assistive communication tool for these people since video communication is not only a tool to break an isolation caused by the disease, but also a powerful way to help people demonstrate their ideas and understand what is said in a conversation with pictures, signs and body language. Therefore, an easy-to-use videophone for people with mild dementia is needed. The goal of this master thesis is to design a graphical user interface (GUI) of an easy-to-use videophone for people with mild dementia according to their characteristics and difficulties of using everyday technology. User centered design (UCD) was used in the design. To get familiar with the user, literature research was conducted before design. Low-fidelity prototype was created. With the help of Karolinska institute’ research group on people with dementia, the prototype was refined twice. Based on the refined low-fidelity prototype, an interactive prototype with navigation, sound and animation effect was created. A usability testing was conducted on older adults with this interactive prototype. In addition to the GUI of functions for people with mild dementia, GUI of functions for other care givers was also created and presented in this master thesis.

Lacome is a multi-user cross-platform system that supports collaboration in a shared large screen display environment. Lacome allows users to share their desktops or application windows using any standard VNC server. It supports multi-user concurrent interaction on the public shared display as well as input redirection so users can control each other's applications. La-come supports separate types of interaction through a Lacome client for window management tasks on the shared display(move, resize, iconify, de-iconify) and for application interactions through the VNC servers. The system architecture provides for Publishers that share information and Navigators that access information. A Lacome client can have either or both, and can initiate additional Publishers on other VNC servers that may not be Lacome clients. Explicit access control policies on both the server side the client side provide a flexible framework for sharing. The architecture builds on standard cross-platform components such as VNC and JRE. Interaction techniques used in the window manager ensure simple and transparent multi-user interactions for managing the shared display space. We illustrate the design and implementation of Lacome and provide insights from initial user experience with the system.
