I’ve heard good things about it’s capabilities from a fellow researcher who has one and has spent a significant amount of time looking at EEG and other measurements for evaluating user engagement.  My own goal is to use the device in order measure a users excitement and/or frustration levels as they interact with (theoretically) any interface.  For the freelance work I do, this will let me add a quantitative and scientifically founded argument to design recommendations that would be qualitatively based using more traditional HF methodologies.

My goal is to spend a week over the summer ramping up on the device, getting a baseline for myself (testing it with video games), and then run a pilot study with 2-3 people to see how hard the process would be to incorporate in a traditional usability test.

• Modified GOMS-KLM analysis, adapted to estimate the time to type using a standard keyboard versus the laser keyboard
• User personas for different classes of users in order to generate use case scenarios for the laser keyboard
• Online questionnaire via SurveyMonkey.com to gather general keyboard use data for the above personas
• Development of Flash based prototypes to evaluate alternate designs for the laser keyboard to improve typing efficiency

I decided to post this to my portfolio because I was particularly happy with the experimental setup I designed to evaluate prototypes of our redesigned laser keyboard.  Our focus was on redesigning the layout of the keys that were projected in order to improve usefulness and usability of the device.  In order to evaluate our different proposed changes our experimental setup, diagrammed above, utilized an Adobe Flash created configurable keyboard (you can try them it below using your mouse) which users interacted with by typing on scaled paper versions of the keyboard layouts that we placed under a glass touchscreen panel.  This allowed us to essentially place the paper keyboard anywhere and configure it how we wished and then just put the touchscreen on top to allow for typing.

Our recommended designs significantly improved typing speed in an experiment we ran to evaluate our design versus the laser keyboard default layout (n=5, p<.05).

The above link is a drawing tha was created as an as-built version of a local New England area hospital. This PDF is one of two floors that were created based on existing blueprints that needed updating and digitization for future planning.

This drawing was produced as a new layout for the expansion of a Massachusetts based medical device manufacturer. The roughly 160K sq ft building was designed for end-to-end production flow efficiencies.  The layout was created to be a macro/micro view of the facility as well as equipment assests and product flows.

Information graphics or infographics are visual representations of information, data or knowledge. These graphics are used anywhere where information needs to be explained quickly or simply, such as in signs, maps, journalism, technical writing, and education.

You can use the flash menus below as you would a normal cell phone basically.  The Motorola version however has limited functions to specific tasks that were required for the usability sessions.

The above show visio clickthrough wireframes that were developed to illustrate suggested imnprovements to Bentley’s FalconNet website.  The PDF version is provided for viewers who don’t have Visio access but it is not interactive.

You can download the wireframe powerpoint file using the link below, but note that not all functionality has been built in as the wireframes were meant to illustrate the process of registering for a GreenT Card and showing some basic features.
