Mobile and Ubiquitous Design blends deep technical systems knowledge with genuine user-centered design — building mobile applications that work seamlessly across an increasingly connected device ecosystem.
What D799 covers
The course blends technical knowledge of computing systems (sensors, processors, embedded systems design, communication protocols, connectivity technologies) with user-centered design principles for functional, engaging mobile applications.
Students apply design thinking and UX methods — user personas, usability testing — to develop scalable, secure, and ethical solutions, with emphasis on privacy considerations and adapting across different user environments.
The D799 performance assessment
Expect a performance assessment requiring you to design a mobile application addressing both technical (connectivity, embedded systems) and UX (usability, privacy) considerations together.
Key topics in D799
- Embedded systems and connectivity technologies
- User-centered design and UX methods
- Privacy and security in mobile design
- Multi-device system synchronization
Writing tips for D799
Follow the task instructions and rubric line by line
WGU performance assessments for D799 are graded against a fixed rubric — every rubric line has to be visibly addressed, usually with a labeled heading that mirrors the rubric language. Skipping a rubric point because it seems minor is the single most common reason a competent submission comes back "Not Yet Competent" for revision.
Show your work: code, reasoning, and test results, not just a final answer
WGU evaluators are trained to distinguish genuine technical work from a paraphrased summary. Include your actual code, algorithmic reasoning, and test/benchmark results, not just a description of what you built — a rubric checking technical competency wants to see the artifact and the thinking behind it.
Because WGU is self-paced, don't let "no deadline pressure" become no submission
There's no weekly due date forcing progress, which means procrastination costs more at WGU than at a traditional term-based school — a stalled task can quietly eat weeks of a term. Treat your own target date for each D799 assessment as a real deadline.

Why students seek help with D799
Students with a strong technical background sometimes under-develop the UX/user-research component (personas, usability testing) — the course explicitly requires both technical and design-thinking dimensions.
