I was wondering if anyone can offer some some suggestions on improving
I'm mostly interested in using sketching for (1) illustrating physical
concepts (e.g. the form factor of a device) and (2) drawing
short-scenarios illustrating use of a product/service etc.
I'm currently comfortable at sketching basic block
diagrams/wireframes, i.e. mostly boxes & arrows.
Would appreciate any suggestions for websites, books, or your
experience with following any short courses in this area.
Thanks in advance,
