Use Case Maps

Friday, February 19th, 2010


Speaking with Greg the other day I learned about Use Case Maps. This notation which has been initially the work of Raymond Buhr, has its roots in software engineering and perhaps could be an area to draw inspiration from. Use Case Maps intend to convey sequences of events by showing the paths of users over a backdrop of structured system representations. With these flexible scenario-like visualizations, software engineers ensure that the element of time is considered. As part of the notation, Use Case Maps have starting and stopping points and can also branch out. It seems like Daniel Amyot has contributed to this work as well and has published a decent Quick Tutorial with a reference guide at the end. In a nutshell, here is what Daniel writes about the philosophy of UCM:

The Use Case Map notation aims to link behavior and structure in an explicit and visual way. UCM paths are first-class architectural entities that describe causal relationships between responsibilities, which are bound to underlying organizational structures of abstract components. These paths represent scenarios that intend to bridge the gap between requirements (use cases) and detailed design.

Exposure Sheets (X-Sheets)

Friday, January 22nd, 2010


Traditional animators have been relying on sketching techniques of their own which I thought might be inspirational. Animators represent time with exposure sheets (aka. dope sheets) through which a large number of information can be conveyed to others. An x-sheet is pretty much a frame by frame representation of time to which notes can be layered on top. Some of these notes typically include information about: dialogue, camera angles, lighting, background and audio. Since timings of around 30 frames per second are standard, each xsheet is just a snapshot of a few seconds. Nevertheless, animators still find them useful as a communication artifact.

Here is what the people at Michael Sporn Animation studios have to say about these deliverables:

You see, when you get used to reading X-sheets, you see them as time. You don’t see the lines, you see seconds and footage, instantaneously. As an animator, you get an overview immediately of the scene; as a director you read the track, how the animator has constructed the scene, and what camera moves are indicated and why.

Here are a couple extra x-sheet samples.

Of course x-sheets work for a passive medium such as film and it’s questionable of how useful they might be for interactive web applications. Nevertheless, I still wonder if some of these ideas can be useful to our field. What other information can experience or interaction designers “layer” on top of the existing deliverables that we are typically accustomed to? Perhaps it would be interesting to combine a user flow representation with a learning curve or effort representation? What ever happened to representing sound in a UI sketch? What about a wireframe referencing an x-sheet sketch for the times when we do use animation? Hey, and what about a user flow with one axis dedicated to representing time consistently? Just thinking out loud.

Present-Future Sketching

Wednesday, December 30th, 2009


I just kicked off a new inspirations category intended for samples and techniques from outside the boundaries of the UI/UX/IA profession. I’m looking forward to seek out some inspiration from within other fields in the new year (please continue to send in samples or ideas). For now, here is a first post in this category.

I’ve noticed that my sister who is in her third year of studying architecture does quite a bit of sketching and model prototyping herself. Looking through her work, one thing which caught my attention was the use of a form of sketching which overlays the envisioned building (or neighbourhood) on top of an existing environment. For me, this seems like a superb and smooth way of transitioning from the present into the future. The present in this case is a black and white photograph of the neighbourhood and acts like a clear reference point. The future state of the intended design clearly stands out by means of a coloured pencil sketch on top of the photograph. Occasionally, I’ve also seen her make use of overlaid tracing paper.

To me this seems really interesting and I wonder if the same approach can be used in UI design. When redesigning existing UIs, why not take screenshots of the current present state, import into Illustrator and sketch the future state on top. Eager to try this one day.
