“It’s a little bit like learning to touch type on a keyboard, but without any formal system or the benefit of the feel of the keys,” says Daniel Vogel, postdoctoral fellow at the University of Waterloo. Vogel wasn’t involved in the research. He notes that “it’s possible that voice control could serve the same purpose, but the imaginary approach would work in noisy locations and is much more subtle than announcing, ‘iPhone, open my e-mail.’ “
Smaller design teams can now prototype and deploy faster.
