Dive Club 🤿 Rooz Mahdavian - Designing frontier interfaces at Neuralink and Apple
16 snips
Oct 3, 2025 Rooz Mahdavian, a design engineer at Neuralink and former Apple Watch Faces team member, dives into the world of frontier interfaces. He discusses the fascinating transition from designing the Siri watch face to brain-computer interfaces. Rooz explores how to empathize with users lacking motor skills and the challenges of innovating a neural cursor. He dreams of a future where visual imagery transfer may become reality, enabling 'daydreaming with computers.' Tune in for insights on creating intuitive designs that redefine user interaction in tech!

Episode notes
Cursor Evolved Into A Circular Reticle
- Early designs used color and tilt to show click ramping but evolved into a circular reticle that collapses to a point.
- Participants found the circular reticle easier to see, target, and use for dwell interactions.
Deleting The Cursor Is The Long-Term Ladder
- The long-term goal is to remove the cursor by directly reading intent to interact with screen points.
- Intermediate rungs include eliminating mode switches and using intent to infer actions like drag or zoom.
Users Rapidly Improve With Daily Use
- Participants improved dramatically with daily use; one user rose from ~2 BPS to 9.5 BPS over months.
- Neural cursor performance can approach trackpad levels with practice and co-adaptation.
