A programmer's interface: a visually enhanced and animated programming environment
Ron Baecker, John W. Buchanan · 2002
The authors describe LOGOmotion, a programming environment that is visually enhanced, animated, unobtrusive, extensible, and monomorphic. The programmer can obtain with ease visual and animated presentations of the execution of programs written in the LOGO language. The programmer can also define new methods of program presentation by writing visualization procedures in LOGO without altering the original program code. Methods may include classical debugging tools such as traces, as well as more modern visualization aids such as the animation of program behavior. The design goals and fundamental principles of the system are discussed. Illustrations of its use and implementation are presented.>
