I recently spent some time playing with the new Moto 360 smartwatch to develop some intuitions about watches as a form factor for wearable technology. And it spurred some thinking about the utility of voice commands as an interface.
Voice is not the future of interface design, and it isn’t going to be even as voice technology improves. Speaking is not a great way to interact with the world. So, while voice technology is worthwhile and has a role, I think it is one of the most currently over-hyped technologies from an interface design perspective.
