The development of assistive technologies is improving the independent access blind and visually impaired people to visual artworks through non-visual channels. Current single modality tactile auditory approaches communicate color contents must compromise between conveying a broad palette, ease learning, suffer from limited expressiveness. In this work, we propose multi-sensory code system that...

Understanding detailed changes done to source code is of great importance in software maintenance. We present Code Flows, a method to visualize the evolution of source code geared to the understanding of fine and mid-level scale changes across several file versions. We enhance an existing visual metaphor to depict software structure changes with techniques that emphasize both following unchange...

Practically since graphic displays were first hooked to computers, the idea of representing computer programs by pictures has attracted researchers. However, to date, most proposals for visual programming languages have adhered to a set pattern: fixed pictures symbolizing program components, connected by lines or arrows symbolizing relationships between the program components. This "icons on st...

Conscious perception of the visual world depends on neural activity at all levels of the visual system from the retina to regions of parietal and frontal cortex. Neurons in early visual areas have small spatial receptive fields (RFs) and code basic image features; neurons in later areas have large RFs and code abstract features such as behavioral relevance. This hierarchical organization presen...
