OnSight
AR app for construction sites
OnSight is a mobile AR tool that helps construction teams document and share context by pinning photos directly in the space. Informed by real construction practices, it offers a simple, low-friction alternative to spreadsheets or high-end BIM systems.

An emerging need
The concept came from interviews with engineers, architects, and builders, where we learned that project changes are constant and historical context is critical. While high-end tools exist, most teams relied on DIY methods like spreadsheets, group texts, or even colored tape to track progress.

Building on an existing behaviour
Despite hesitation around adopting new tech, workers were already using their phones to take and share progress photos. We saw an opportunity to add value without adding extra steps.

A shared visual memory
We created OnSight, a simple augmented reality documentation tool for teams working on physical job sites. The mobile app allows users to place photos directly in physical space, creating a shared visual memory of progress, notes, or context—right where it’s needed.

From paper to Unity
We started our basic prototyping with tracing paper, and switching to Adobe Aero and Polycam to validate the interaction. I was responsible for building the final app in Unity.

An issue came up in the field yesterday that the app would have been perfect for! Maintenance folks and even the building users (especially in highly technical spaces like labs, R&D facilities, manufacturing) are always trying to locate sensors, valves, etc, that are hidden. The current way they store their location is spreadsheets and tribal knowledge

I think you guys are on the right track! You guys asked many good and right questions. I look forward to seeing the final product!

It seems like that would be a good complement to something like a VR BIM! I think you might want to think about the market. Residential construction is usually pretty cheap, I think it would difficult to find a market with buy-in, but this type of thing is definitely growing in things like industrial construction on really complicated projects.
