It's really hard to design products by focus groups. A lot of times, people don't know what they want until you show it to them.

Kacmar, Charles J. (1993): Supporting Hypermedia Services in the User Interface. In Hypermedia, 5 (2) pp. 85-101.
This paper presents an architecture for developing hypermedia systems in which hypermedia services are provided primarily through the interface and hypermedia components of an application. The architecture relieves the application component and its developers from the issues associated with hypermedia. It also allows a common hypermedia engine and interface to be used in multiple applications to present a consistent view of a hypermedia model. A prototype of the architecture is presented with examples of the hypermedia facilities which can be provided. The discussion associated with the prototype demonstrates that many of the common features of pure hypermedia systems can be supported. Limitations and future research issues also are discussed.

Kacmar, Charles J. and Carey, Jane M. (1991): Assessing the Usability of Icons in User Interfaces. In Behaviour and Information Technology, 10 (6) pp. 443-457.
This paper presents a methodology and results of an experiment to assess the usability of menu items constructed of text, icons, and text-and-icons. Attributes of menu items are used to form a matrix which can be used to classify menu items for use in certain applications, tasks, or with users of particular experience levels. An experiment was conducted to validate a portion of the attribute matrix. Performance measures were accuracy of selection and time to make a selection. Results suggest that menus constructed of a mixed format (text and icons) result in the fewest number of incorrect selections by users. No significant differences in the time to make a selection were found.

Kacmar, Charles J. and Leggett, John (1991): PROXHY: A Process-Oriented Extensible Hypertext Architecture. In ACM Transactions on Information Systems, 9 (4) pp. 399-419.
This paper describes the design and prototypical implementation of an architecture for hypertext systems which is based on the process and object-oriented models of computation. Hypertext services are provided to applications through object-based distributed processes which interact using interprocess communication facilities. By merging the process, object-oriented, and hypertext models, hypertext data and functionality can be separated from applications and distributed across a network. This architecture allows links to cross application boundaries and diverse applications to be integrated under a common hypertext model. The paper describes the architecture and application requirements for operating in this environment. PROXHY, a prototypical implementation of the architecture, is also discussed.

Kacmar, Charles J. (1989): A Process-Oriented Extensible Hypertext Architecture. In ACM SIGCHI Bulletin, 21 (1) pp. 98-101.
Previous hypertext systems have been designed in a monolithic fashion. This design has inhibited the ability of hypertext systems to be extended or to interface with other systems. A new architecture for hypertext systems has been developed. This architecture is centered around the process and object-oriented models of software construction. The architecture provides hypertext functionality outside the application, allowing applications to draw upon those hypertext features appropriate to the application. The architecture also extends hypertext functionality so that inter-application as well as intra-application information links can be formed.
