As Facebook looks to the next stage of digital connection, which includes the development of its own AR-enabled glasses, it’s also working on new control tools that will enable people to interact more seamlessly with these overlays and options. Such controls are a key part of the experience – in order to make best use of AR overlays, you need to be able to interact with them easily, without disrupting your everyday tasks. Voice commands are one option, while other research has focused on eye-based controls, with varying results. But Facebook’s research has actually pointed them to the wrist being the key control point for such interactions.
