Title: Complexity Evaluation of Computer-Based Tasks.
Authors: Bedny, GregoryZ. (AUTHOR), Karwowski, Waldemar (AUTHOR), Bedny, InnaS. (AUTHOR)
Source: International Journal of Human-Computer Interaction. Apr2012, Vol. 28 Issue 4, p236-257. 22p. 1 Color Photograph, 5 Diagrams, 4 Charts, 1 Graph.
Subjects: Computer interfaces, Computers, Computer interfaces software, User interfaces, Activity coefficients, Structural optimization, Design techniques
Abstract: In this work, task complexity is considered as a multidimensional, integral characteristic of a task. The more complex a task is, the higher the cognitive demands for performing the task. Components of task complexity impose demands on the mental efforts of users. This article proposes a general approach to evaluate the complexity of computer-based tasks. The proposed principles of complexity evaluation and measures of complexity provide a proper basis for optimization, modification, and enhancement of the software design process. Experimental results support the effectiveness of the proposed method for both the design of man–machine systems and human–computer interfaces. The suggested methods and principles of complexity assessment derive from systemic-structural activity theory. [ABSTRACT FROM AUTHOR]
