The Computer’s Role in Sketch Design: A Transparent Sketching Medium

摘要: Starting from an analysis of the current unsuitability computers for sketching, three key requirements are identified, in particular notion that re-drawing or over-drawing more important than editing and tweaking. These encapsulated broad concept Transparency, understood both literally metaphorically. Two experiments implementing aspects Transparency described. One subverts Macintosh window manager to provide windows with variable transparency, so tracing between applications becomes a practical possibility. The other implements graphical interface requires no on-screen palettes sliders control it, allowing uninterrupted concentration on design hand. User tests show tool can be learnt quickly, is engaging use, most importantly, has character.
