John Javes Usability Case Studies

I am committed to developing Web experiences which provide a deep level of usability.
I commonly use techniques such as cognitive walkthrus and task analyses to gain insights from personal user experiences.
I have used server-based click-trail analysis with great success
I choose to use technologies to replace customization (User-invoked) with personalization (machine learning)
I use Web Standards and ADA 508c coding techniques
I strive for a Semantic Web of Linked Data, having used Lexical, Ontological, and Taxonomic tools.
The figure below describes how rapid prototyping supports Usability discovery and testing.

I designed a printed annual report for the STAR METRICS program with inDesign.
I re-engineered a collection of reports to be delivered in a single set of Excel documents.

I designed and coded this interactive timeline for Dr Collins' use. Visit http://s118158764.onlinehome.us/nihinvestment/collabs1.html

I designed and coded the front end to this White House initiative. Visit http://starmetrics.nih.gov/

After the success of version 1, I improved the design and made design changes. This design won two PROSE awards.

Early prototypes of this initiative were critiqued in a New York Times article
The progress of the prototypes were validated thru Scientist interviews and questionnaires.
Task analyses showed that researchers needed a better way to view articles and high-resolution figures interactively and simultaneously. This prototype solved the problem by using Javascript and JQuery techniques to present scaleable figures alongside the scrolling article.

PJM manages the electrical grid for the US East Coast. I helped a design a new application for the Control Room.
I conducted interviews with engineers and dispatchers, focusing on Contextual Inquiry, Cognitive Walkthrus, and Task Analyses.
A snapshot of the upcoming rTivo AJAX/SOA application is attached.

The Comcast Video page http://www.comcast.net/video is representative of the dozens of pages I constructed using JSP, JSON Javascript, JQuery, Prototype and CSS
This image is a snapshot of the upcoming rTivo AJAX/SOA application, which was integrated into the Comcast TVGrid. The development releases were subject to rigorous heuristics and usability tests internally.

I conducted extensive interviews with Government and industry stakeholders, researchers, program managers
One result of user research was to offer sorting on 4 taxonomic dimensions for each search as seen in below in blue.
Other results were to offer a Project Portfolio Management and Community features
I became involved with US Government Semantic Web efforts using Ontology technologies such as RDF/OWL

Used with Internet Explorer 6, IQPlus is a major application design which resulted from superior Usability techniques and design.
Persona discovery and analysis resulted in a role-based login for 5 user workflows.
Task analyses resulted in a restricted browser size which took up only one-quarter of the screen, and a mouse-free input layout for most users
The application uses many original CSS and DOM JS tricks such as AJAX, a unique focus hiliter and original icons. In particular, the Routing History shows a unique table scroller which maintains headers on both x and y axes.

eBilling application. Navigational Mapping (XLS) and new navigation/page flow (PDF)
Group Portal
The ccDashboard is a major application design with good UX and design. These pages show AJAX calls with XML and original text field ‘Auto-complete’ coding. Admin Form and Broadcast in particular.
VAST

Click the War Room Viewer to see comp screenshots from the application which hangs in the FCC Auction Rooms. I designed the application from scratch, with input from mathemeticians, auctioneers, attorneys, Auctions Bureau management. I conducted Contextual Inquiry and Card Sorting to determine which data clusters to be shown at each interval. This application is currently in use for all auctions in Washington and Gettysburg. I coded the Actionscript to receive and format XML pushed from a server.
This Auctions Form page is just one ‘clickable’ flows which leads to 508c pages for which I conducted the IA, UX, and coding. I conducted end-user testing to validate these designs.
Auctions Administration Console shows advanced uses of CSS and Javascript for the FCC

InteliHealth won two Webby awards, which had much to do with the usability of the site. I used a wide range of techniques to plan and adjust the site. Sitemaps, Wirframes, card sorts, user interviews wrere often used.
I implemented a clicktracking system which allowed us to determine how traffic would change with changes to the navigation.
I was involved with efforts toward improving find-ability, utilizing NIH PubMed, UMLS, Autonomy, lexical technologies, ontologies and taxonomies.

I began my career as an Art Director in the Direct Mail industry, which used scientic methods to maximize returns.
These techniques included eye-tracking and A/B split tests.
