Advances in visual programming

The use of visual information in programming is called visual programming, where the program specification is carried out through spatial manipulation of visual elements on the screen. Visual programming provides more direct communication between human and computer and makes it easier to create programs. The authors first observe approaches to enhance the performance of programming and show how visual programming contributes toward the success in developing advanced programming systems. They explain a visual programming case study using an iconic programming system called HI-VISUAL, including a support environment for the construction of a variety of visual programming systems under investigation
