the voice with vision

My favorite classroom in the Allen School isn’t a classroom at all. It’s the research commons: CSE2 250. Even though it’s meant mostly for PhD students, it has become the place where I stay close to the pulse of the department. Sitting at the kitchen island, I fall into conversations I could never plan for: an AI security researcher sketching out an adversarial attack, an ethics researcher wrestling with dataset consent, a professor of computer graphics explaining how light behaves inside a shader, a computational biologist describing how structure grows out of sequence. Those moments have shaped me more than any class.

On November 19th at 2:11 PM, a different kind of moment found me.

I was talking with Aryan, one of my closest friends, when someone walked in whom I’d seen around the building before but never spoken to. With a coffee-stained cup in one hand and a mobility cane in the other, he moved carefully but confidently toward the sink.

I introduced myself. His name was Nakul.

He grew up in Bangalore, came to the US to study HCDE, and now works as a UX researcher at the Taskar Center for Accessible Technology (TCAT). He designs the non-visual layer of AccessMap, translating elevation changes, curb ramps, tactile landmarks, and turns into a spoken map. It sits atop OS-CONNECT, the AI-generated, human-vetted sidewalk dataset TCAT pioneered for Washington State. Our conversation lasted maybe twenty minutes. After he left, Aryan and I just sat there for a moment, thinking about everything we didn’t know we weren’t noticing.

I can walk through the world without ever calculating the slope of a sidewalk or the width of a crossing. My body reads those features without effort. For Nakul, every one of them is the difference between independence and dependence.

Aryan stood up, motioning for me to follow. We walked to the tall window framing Lake Washington. He asked me to close my eyes and spin a couple of times, then find my way back to my seat. Within seconds, the room I’d known for years turned strange, uncertain, uneven. That brief disorientation revealed the distance between our world and Nakul’s.

Accessibility is not a feature. It’s a worldview. It’s the discipline of noticing all the quiet assumptions built into the world, and asking who gets excluded when we stop questioning them.

Nakul didn’t just tell us about his work.

He showed us what it means to navigate using something deeper than sight.
