Design can be art. Design can be aesthetics. Design is so simple, that's why it is so complicated.

Gong, Qing and Salvendy, Gavriel (1995): An Approach to the Design of a Skill Adaptive Interface. In International Journal of Human-Computer Interaction, 7 (4) pp. 365-383.

Computer users vary greatly in their abilities to use a software interface efficiently. One factor that apparently affects users' efficiency in using an interface is the changes in their skill levels. In this study, an adaptive interface (of menu and command) is presented that dynamically adjusts to users' changing skill levels. The mechanism of an adaptive interface is described and discussed. The validity and usability of the adaptive interface is tested with 40 participants in an experiment that used a between-subject experimental design for interface style. The independent variables were interface style (menu, command, hybrid, and adaptive) and skill level (starting session and ending sessions). The dependent variables were task completion time, number of steps used, ratio (of using menu mode over menu and command modes), perceived memory load, and satisfaction with the interface styles. The task-completion time and ratio data indicate that the adaptive interface produced significantly better performance than the static hybrid interface at the end of the training sessions for experienced computer users. No significant differences were found for memory load and satisfaction ratings across the four interface styles.

Gong, Qing and Salvendy, Gavriel (1994): Design of Skill-Based Adaptive Interface: The Effect of a Gentle Push. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 295-299.

To accommodate individual skill differences in using a computer interface, a skill adaptive interface was designed and tested. Current human-computer interaction modes can be classified into two types, recall and recognition based interfaces. They have different memory requirements and generally allow different operating speeds and learning time. However, a static combination of the two interface modes has drawbacks. The dynamic skill adaptive interface introduced in this study tries to eliminate these problems without sacrificing the advantages from either interface modes by gently 'pushing' users to switch to the appropriate interface mode. Experiment showed that the adaptive interface can yield significant better performances than the static hybrid interface for certain groups of users.
