Diaz, Leonel Morales and Leon, Jose Luis de (2008): An Empirical Verification of the Foundations of Structured User Interface Design SUID. In: ENC 8. Mexican International Conference on Computer Science October 6-10, 2008, Mexicali, México. p. 8. Available online

“This paper is a report on the research being conducted at the Universidad Rafael Landívar of Guatemala on the development of a design methodology for user interfaces and interactive systems in general. At this stage of the research we tried to test the methodology's fundamental supposition: that every information system is devoted to handle a certain set of objects from the real world and that based on the proper identification of that set, the interface can be designed in a layered fashion producing ten different layers, specified in the methodology. Several user interfaces were picked and through a reverse-engineering process, the main set of objects was identified and the ten layers described for each one. The results revealed positive features of the methodology as well as nuisances, and, at the same time constitute the first empirical verification of the underlying suppositions.”

Diaz, Leonel Morales and Perezgil, Arturo Rivera (2007): Evidence of Bias in the Production of User Test Lists by Software Analysts, and Proposed Mitigation Strategy. In: Latin American Conference on Human-Computer Interaction CLIHC 2007 September 10-11, 2007, Rio de Janeiro, Brasil. . Available online

“In the absence of sufficient HCI professionals, user test lists are generally developed by people with intimate knowledge of the software product in case. It has been seen that this may lead to bias when the language employed in the lists hints the user on how to perform the tests within the context of the application. This document presents empirical evidence of such bias and proposes a strategy to minimize it.”

Diaz, Leonel Morales (2006): Los Tres Momentos de Toda Interacción Humano-Computador. In: Primer Taller de Interacción Humano-Computadora en México Oct 24-25, 2006, Puebla, México. . Available online

“Bajo los lineamientos de interacción humano-computador de mayor uso en la actualidad, se pueden identificar claramente tres momentos de interacción en todo diseño: selección, interacción con lo seleccionado y revisión histórica de la interacción. En este trabajo se pretende mostrar que estos tres momentos son ineludibles y que deben ser parte de todo diseño de interfaz de usuario. Su consideración por separado presenta importantes ventajas como componente metodológico de la ingeniería de la interacción humano-computador.”

“This extended abstract describes the research in progress to develop a methodology to deploy user interface designs based on a layer-conformed structure. Final descriptive designs are achieved when all layers are specified.”

Diaz, Leonel Morales (1999): Strategies for a Better User Interface. In ACM SIGCHI Bulletin, 31 (3) pp. 21-23

“Even though it has not been formally defined what a user-computer interface is; it is possible to describe the challenges and compromises a system designer must confront to approach that definition. The way those challenges and compromises are solved represents, more than a simple formalism, an strategy, which means, an ingenious solution not necessarily according to the traditional methods for problem solving. The challenges in the user interface design process may be a lot, so the strategies are also a lot, but, it is possible to organize that set of decisions into five principal groups: 1. Challenges and strategies for representation 2. Challenges and strategies for localization 3. Challenges and strategies for acquisition and actualization 4. Challenges and strategies for creation, change and destruction 5. Challenges and strategies for action and response Confronting those five challenges and defining the corresponding strategies the complete design of a user-computer interface is achieved.”
