The team was specifically concerned with cords, because they can be attached to the hood of a hoodie, for example. With that, Google could eventually make a smart piece of clothing.
The experimental cord was able to control a smart speaker with different movements. A tap on the cord paused or resumed the music, while a twist of the cotton changed the volume. In a second practical test it was possible to scroll through a website with a twist of the cord.
The Google team used artificial intelligence to develop the software used. Twelve people made 864 movements with the cord together, after which the AI linked that to certain actions.
Built-in lights should provide feedback. For example, they turn blue when you turn the cord in the right direction or they flash when an incoming message arrives.
It will probably take a while before we encounter the technology in the wild: the search giant has only made prototypes at the moment. Plans for a concrete product have not yet been announced.
