Debugging PCBs with Augmented Reality

The idea of InspectAR is to use augmented reality to help work with and debug electronics. It’s a powerful suite of tools that enable the live overlay of graphics on a video feed of a circuit board, enabling the user to quickly and effectively trace signals, identify components, and get an idea of what’s what. Usable with a smartphone or a webcam, the aim is to improve collaboration and communication between engineers by giving everyone a tool that can easily show them what’s going on, without requiring everyone involved to run a fully-fledged and expensive electronics design package.

The Supercon talk served to demonstrate some of the capabilities of InspectAR with an Arduino Uno. With a few clicks, different pins and signals can be highlighted on the board as Mihir twirls it between his fingers. Using ground as an example, Mihir first highlights the entire signal. This looks a little messy, with the large ground plane making it difficult to see exactly what’s going on. Using an example of needing a point to attach to for an oscilloscope probe, [Mihir] instead switches to pad-only mode, clearly revealing places where the user can find the signal on bare pads on the PCB. This kind of attention to detail shows the strong usability ethos behind the development of InspectAR, and we can already imagine finding it invaluable when working with unfamiliar boards. There’s also the possibility to highlight different components and display metadata — which should make finding assembly errors a cinch. It could also be useful for quickly bringing up datasheets on relevant chips where necessary.
