Paper Abstract:
|
Usability is the main requirement for developing modern graphical user interfaces. We focus on usability of visual programming languages (VPLs), which allow software developers to create programs by manipulating program elements graphically. As common usability evaluation methods based on user surveys are subjective, we research objective computational measures based on characteristics of visual elements to evaluate language usability. The paper presents the analysis and evaluation of usability of main graphical elements of popular VPLs in robotics domain (Microsoft Visual Programming Language, Lego NXT-G) using visibility and complexity metrics based on the Physics of Notations approach, and formulation of recommendations for visual elements of new visual programming languages. |
