Donning a Fitbit and a heart monitor, Juli weighed himself using a connected scale. He followed that up by simulating a workout on stage and would ask questions such as "SAMI, how am I doing?" There is some speculation that the virtual assistant will eventually be able to answer you by telling you that you need to train harder, or that it was time for a break.
Unlike Siri, which works on the one device only, SAMI would be able to connect to other devices. It can also take the data from the scale and the Fitbit and combine it together into one app. The project is said to be in its early stages and Samsung has invested about 6 months in it. Those familiar with SAMI say that it could take three to five years before it is ready for consumer consumption.
