screening research participants

tl;dr know which participants you need to conduct research that generates value and design screeners to ensure that you get them.

We recruited people through […]

better communication means better product

Many product development problems are complex or [shudder] wicked. They’re more intricate than they may seem, they change over time, and they involve humans. It may seem paradoxical, then, to say that a significant contributing factor to product dev problems is simple to express: communication is the problem someone somewhere A lot of the problems […]


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 […]

Here’s how the service works: PVI connect with a remote sighted assistant via a mobile app and, using a smartphone […]

(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 […]

Their comments and […]
