Visualization for the Mind's Eye

摘要

Software visualization has been almost exclusively tackled from the visual point of view; this means visualization occurs exclusively through the visual channel. This approach has its limitations. Considering previous work for blind people we propose that complementing usual approaches with those techniques used to develop interfaces for non-sighted people can enhance user awareness of logical structures or data types using different perception channels. To achieve better comprehension, we deal with new or augmented interfaces built on top of standard systems for data visualization and algorithm animation. The notion of specific concept keyboards is introduced. As a consequence, modem information and learning systems can be designed in such a way that not only sighted but also blind users can navigate within these systems.
