The usage case is great but I think we are selling spatial computing short if its just floating windows. Bar the bug identification (which it is likely an experienced Farmer will recognise anyway) there isn’t anything there that couldn’t be done using a phone app for less cost and resources. Heck, he might even have the whole thing automated anyway: the system alerts to the presence of bugs, a robot goes out and uses AI to identify them and deploys the drone anyway.
Spatial computing needs to make use of actual space. Say the Farmer still likes to walk the crops, I imagine a scenario where the use of external sensors, IOT sensors and GPS allow the AR glasses to show a suspended icon floating above the infected corn field showing an error which then prompts the physical investigation.
We’ve skipped over the need for floating windows and allowed the system to provide physical feedback to the farmer directly.
