Long description for slide: Sharing synchronous blackboard notes & sketches

This simplified image has three columns:

1. visual, audio and tactile processing
2. generating text e.g. writing on the blackboard with text tool, graphic objects e.g. drawing ovals and rectangles and spatial info e.g. location of the text or graphic objects
3. arrows describing transformations between generating and processing of content

Transformations with research opportunities are marked with black boxes. They go from spatial info to audio processing or to tactile processing. There are a lot of opportunities for research.

Note: Cognitive processing is missing from this image to keep it simple. It would add next level of challenging transformations and research opportunities. Also the processing components could be divided into several subtypes to highlight more restrictions.
