Easier User Interface Design for Embedded Systems
There are some common rules in the design of
user interfaces (UI) in embedded systems, such as, “use common dialogs and
buttons familiar to your users” or “keep it simple by limiting user activity, as
much as possible, within the context of the current function”. However, the
design of these buttons, dialog boxes, help screens and other widgets are not
always easy to create in resource-limited embedded systems. Furthermore, the
amount of time it takes to develop the widgets may limit their use in a UI
design and negatively impact the end user’s experience. What is needed, is an
easy and efficient way to create these widgets. This webinar introduces the GUI
library now included in Keil™ MDK-ARM™ Professional Edition that addresses some
of the common hurdles in UI design for embedded systems.
Key takeaway points:
- Design in advance, and design as an end user, not as the programmer
- Have enough context clues so that a user can walk away and come back, and
know what they were doing
- The system should feel safe so the user can muddle around (i.e. anything
that is destructive should have a confirmation screen)
