Ouch.

Guidelines will cover:

interaction and behavior models,graphic design (including layout, grid, color palette, type and naming conventions),information architecture,technical implementation

We need a simple set of design best practices that

… takes a system approach to design

…. accelerates good software behavior and interface design pattern adoption

MOBILE DESIGN TENETS

Let data scream

Envisioning Information, E. Tufte

and the Problem is…

Increasingly complex systems– Tool and Methodology gap

Decision makers are swamped with conflicting data– Our work is increasingly multi-dimensional (not a flat-

decision space)Artifacts driving decisions need to be coordinated,

presentedMinimal transparency into key health metrics

How do I (as a patient, nurse, doctor, proxy) make quicker, more accurate decisions?

Ink and lines screamData disappears

Violates all 5 Tufte principles

5 principles produce substantial changes in graphical design:

1. Above all else, show the data.2. Maximize the data-ink ratio (i.e., the % of ink that shows data)3. Erase non-data ink.4. Erase redundant data-ink.5. Review and edit.
