Long description for slide: Sharing Web content

Until we concentrate on what is missing, this image shows what is available.

The simplified image has three columns:

1. visual, audio and tactile processing
2. image, text, video, and audio content
3. arrows describing no need for transformations or commonly available transformations between processing and content

No transformations are also needed in trivial cases, such as processing audio content as audio, or processing image content visually.

Commonly available transformations are marked with green oval and go from text content to audio (screenreader) or to tactile (braille device) processing .

Text is has a green highlight as it is generally easy to transform and process, and visual processing is marked green as it can handle most of the content types (except audio content) without transformations.

Note: Cognitive processing is missing from this image to keep it simple. Also the processing components could be divided into several subtypes to highlight more restrictions.
