A usability review of a simplified storage management application called Simplicity subsequent to what the scope of a usability test did not cover. [LSI Logic] -- Contact me directly for this work sample.

The GUI for a feature/function enhancement that encorporates replacing failed and/or missing drives within a volume group in the Java-based storage management application called SANtricity. [LSI Logic] -- Contact me directly for this work sample.

The GUI for a feature/function enhancement that encorporates a drive channel fault isolation diagnostic in the Java-based storage management application called SANtricity. [LSI Logic] -- Contact me directly for this work sample.

Results of usability test I conducted on LSI's SANtricity Storage Manager software. [LSI Logic] -- Contact me directly for this work sample.

A usability review of six Sabre products. I reviewed six Sabre web sites on a freelance basis for a consulting firm which then compiled a formal report of the three independent reviewers. [Freelance consulting]

A usability review of a proprietary search technology created by a Dutch software company called MediaLab. My review identifies 39 issues and recommendations. While the review is written in English, the web sites were implemented in Dutch. This posed an interesting challenge for me since I did not know Dutch! However, the task soon proved that regardless of language good UI design and usability principles are universal. [Freelance for MediaLab]

Design recommendations generated from HCI research regarding interaction design issues within Social Security Administration. [Consulting at SSA]

The summary of an informal usability test I conducted with targeted users on an early version of i-opener. The goal was to quickly identify usability issues and to redesign solutions for them. [Netpliance]

As an aid to the design and development process at Netpliance for the i-opener internet appliance, I set system performance objectives and underscored the implications of the objectives for the i-opener user experience. [Netpliance]

While working in an agency environment, I researched user groups on location and wrote the HCI strategy (PDF file) for a client business line during a cross-functional strategy consulting engagement at Prudential Relocation Services. The strategy includes summaries of user profiles, task assessment, and site maps of the proposed information architecture for each of four user categories. [EDS - c2o]

As part of a client web site redesign, I conducted a quick competitive assessment (PDF file) for ELLE Magazine that went into the overall strategy plan for the redesigned web site. [EDS - c2o]

The information architecture of the i-opener information appliance combined portal-type content and applications on a proprietary consumer electronics device. When content and applications for the service evolved, I constructed first and second level site maps that demonstrated integration of new content and applications with the existing i-opener services. Below are such site maps. [Netpliance]

One of the applications for the i-opener was an instant messenger (IM) called iChime. After setting the requirements for iChime, I constructed a Visio diagram illustrating the information flow of the IM functionality. The diagram was used in design reviews, building the HTML wireframe, and in the UI design specifications. Within this process I also sketched a UI design storyboard of the user scenario. This is the iChime main page sketch I created for the storyboard, which served as a tool for illustrating the user interaction, system behaviors, and for roughing out the page layout of the whole application. The sketches also served as the basis for the visual comps completed by the visual designer working with me. As far as I am aware, my design was the first instant messenger application that used tabs to manage multiple conversations. This was the challenge I had to solve with a "single-document interface" product. [Netpliance]

The design of the i-opener web browser bar illustrates the challenge I faced with balancing browser functionality and keeping the simplicity goals of the UI for our targeted users (elderly users that were extremely novice user types, combined with limited screen resolution of 800 X 600 pixels). The simplicity goal was to keep features and functions in direct view of users, thereby avoiding the usage of menus and controls that hid information from view and caused functions to be too inaccessible to our user group. Likewise, you may be able to tell from the design that our users required relatively large labels and fonts. [Netpliance]

After an iterative process of design, evaluation, and redesign, I wrote a UI design specifications for the various functions. Here's an example of a simple UI specification on a function within the web browser bar, the font size control (aka - "font magnifier"). [Netpliance]
