User Experience

This is fascinating work that I got into while I was studying Occupational Therapy (OT). Occupational Therapy is a career for improving a person’s quality of life if they have a disability or suffer an injury. Listening to NPR one day, I heard Clifford Nass talk about his book, “The Man Who Lied to His Laptop.” I immediately bought the book on Kindle and read it in the little bit of free time I had. That book, combined with what I was learning about assistive technologies in OT school, lead me to study Human-Computer Interaction.

As an HCI student at Georgia Tech, I learned that my experience with documentary filmmaking, providing therapy to people in distress, communicating information between doctors, patients, and other caregivers, and, finally, analyzing research studies to pick out possible biases and flaws in the research gave me an edge in conducting user studies.

My first project involved studying people with visual impairments to determine their exercise patterns or lack thereof. We determined there was a need for treadmills to be more user friendly for this population, specifically because running outside when you are blind can be quite dangerous, or even walking fast, for that matter. The people we interviewed were desperate for accessible treadmills. We would have loved to create visually-impaired friendly roller skates, but we chose a treadmill because that’s what our users needed.  We created a prototype and tested it with several visually impaired users.

My Master’s project focused on improving the work flow for video editors, particularly those working on documentaries. I conducted several phone and contextual interviews with editors to determine a user problem that I could solve. My hypothesis was that a speech recognition plug-in for a video editing software program would solve the problem of typing transcripts of all the footage. It turned out that there is speech recognition available, but the technology for speech recognition wasn’t up to the task. Besides that, editors add much more information to their transcripts than speech recognition could detect. There’s visual information, tone of voice, laughter, and broad subject matter topics that are useful to have typed into a document for ready access when composing a documentary. I ended up making a physical prototype along with a new software program that would allow an editor to quickly type transcripts while being able to control the playback of the video without their hands leaving the keyboard. Several editors asked me how they could buy the prototype at the end of the project.
