Tommy Tai · independent builder and researcher
I worked as an exercise therapist before building browser experiences, spatial input systems, and tools for checking the work of AI agents. The common thread is practical feedback: observe what happens, make a useful change, and test whether it really worked.
The through-line
My earlier work was with people and physical movement. That background still shapes how I think about feedback, accessibility, and whether an interaction actually makes sense to a person using it.
I started turning cameras, gestures, and ordinary browser input into playable experiences. The larger Spatial Input work aims to translate noisy sensor observations into stable events an application can use.
Working with AI coding agents led me to build checks for false completion claims and brittle self-review. I now publish public tools, demos, and research packets with their evidence and limits attached.
Selected work
Spatial interaction · public alpha
A webcam gesture piano that turns tracked hand movement into notes through filtering, dwell, and hitboxes. It is a public experiment in the Spatial Input family, with tuning still in progress.
Browser games · playable
A hub of small browser games. They use ordinary touch, mouse, and click input; the gesture experiment above is a separate demo.
Open tools · source
Open checks and a field guide for AI-agent reward hacking, false-green claims, and the gap between an agent saying “done” and a result another person can verify.
Research · dated packet
A 422-operation scalar-inversion candidate with a frozen certificate and independent reconstruction checks. The note explains the search and explicitly bounds the claim.
