Listed on GitHub, the experiment is called Project Oasis and is a voice controlled terrarium that recreates outside weather inside a box. You can talk to it through Google Assistant to ask about the weather or ask it to create certain conditions.
The terrarium, which comprises of three modules: Dialogflow functions, Cloud PubSub NodeJS listener and Arduino sketch, recreates rain, clouds and lighting in a self sufficient closed and living ecosystem.
According to the details on GitHub, the developers used Google's Dialogflow to parse natural language for the required parameters of city, location or action. User's voice input are mapped to actions or functions exported in the Dialogflow fulfillment.
“These functions use openweathermap api to extract information about clouds, rain, light conditions at a particular location. The result JSON is passed onto the terrarium using Google's Cloud PubSub -- a realtime notification system. PubSub messages then trigger appropriate components within the terrarium,” it said.
For example, if you ask about the weather in New Delhi, the terrarium will recreate the weather with light, shooting mist (for fog or clouds) or rain depending upon the current weather conditions of the capital city .
Google has also given users a (fun) glimpse of how far its natural language processing technology has come. Google Research division of the search-giant has rolled out Semantic Experiences, which are websites with interesting activities that demonstrate AIs' ability to understand how we speak.
