What we are working with is the 120° between the back projected screen, in order for it to be possible to turn left, turn right to address the person. One might want to see a little bit of the other party's sketching table, like above, since it brings the spaces closer. Then again, you want your colleague to draw on the same paper, so that makes it impossible to see too much.
Now we are experimenting with different kinds of surfaces, interactive, touch screens compared to whiteboards etc - ways in which we can integrate some of Peter Parnes' ideas of objects that carry meaning, and ways to 'place a bid on the table'
