reflection improves communication

tl;dr If you’re not reflecting on your product practices, then you’re going to have a hard time improving them. Today I reflect some more on communication. When you’re the communicator, you have the power to establish a clear frame of reference for your audience in order to minimize the possibility of misunderstanding, accurately convey research […]

Co-designing Platform Collectivism

Abstract: We report a codesign effort to envision a community water quality data platform with local stakeholders. We employed interviews, field observations, and hackathons through a 9-month study (ongoing). This codesign effort helps to distinguish our proposal of platform collectivism, in which local resources and stakeholders become more visible, accessible, and engaged with one another […]


Super excited that our (Omar Sosa-Tzec and John M. Carroll) submission to SIGDOC was accepted and that we’ll be publishing a full paper in the ACM digital library to accompany the presentation. The paper takes an existing thread of my research in an exciting new direction, and I couldn’t have done it without the insight […]

GroupMe Projects

For the final project in my undergrad human-centered design class this year, I gave students a design brief focused on GroupMe. The challenge was broad, and the deliverables were diverse and interesting. In addition to generating presentations, I asked students to create one-sheets showcasing their projects. One of the teams (David Lu, Alex Yun, Kevin […]

The speediness of these revisions is due to a stellar graduate student who is also the instructional assistant who helped me teach the class […]

Scenario-based Design Courses

I’m looking for syllabi or links to online courses focused on scenario-based design. Instructive case studies, methods, tools, techniques, and assignments. All of it. If there aren’t lots of resources out there, then I’m also curious to know whether there is an interest for such a course.  

conversations for vision

Another new pre-print dropped this week. This paper is a first draft of our findings from an interview study conducted with a fascinating group of practitioners who work to support people with visual impairments (PVI). Here’s how the service works: PVI connect with a remote sighted assistant via a mobile app and, using a smartphone […]

Image-based Reference Management

Here are some true statements. (1) Some of my colleagues share paper copies of interesting, relevant research with me. (2) I find new literature on devices that aren’t mine. (3) Manual entry of new literature is sort of a pain on a mobile device. I want to be able to quickly add relevant literature to […]
