Picture walking around an airplane fuselage holding an SMR (a spherically mounted retroreflector) while a laser tracker follows your position in 3D space. Every measurement point matters, and the monitor showing the results is 30 feet away over your shoulder. That was the reality of large-scale metrology before this project
Verisurf Watch put a digital readout on the technician’s wrist. It’s a watch companion app connected to the REST API that delivers live measurement data to the Apple Watch: probe-hit notifications, pass/fail status, deviation values, and inspection progress, with haptic feedback on every contact. Instead of turning around to check a monitor across the shop floor, you glance at your wrist and keep working. For technicians doing large-volume inspection with laser trackers, that is a meaningful change to the workflow.
// Probe hit notification on Apple Watchfunc onProbeHit(result: MeasureResult) { let status = result.inTolerance ? "PASS" : "FAIL" displayResult(status, result.deviation) hapticFeedback(result.inTolerance ? ".success" : ".failure")}It shipped as a real product on both the Apple App Store and Google Play. It supports stationary and continuous display modes, works with any Verisurf-connected device, and puts live DRO data where it is actually useful: on the technician, not on a monitor across the cell.
Build DRO values stream in real time to iOS and Android watches. It took two iterations to go from proof of concept to production. The second pass added richer visualization, better glanceability, and tighter integration with inspection plan workflows, which is what made it usable as a shop-floor tool rather than a companion novelty.
The phone side
The watch pairs with Verisurf Companion, the phone app, which covers the rest of the workflow: tap-to-measure with a feature-type picker, a live Build DRO with per-axis and 3D deviation, pass/fail reports, and device settings. It runs on iOS and Android and is currently on version 2.4.
