Voice control? In a busy open plan office?
As the title - voice control works really well, in a quiet environment. Quiet is not a word I'd use to describe our office, add everyone
shoutingtalking at their computers and it would be horribly noisy. Plus the potential for my neighbours PC responding to my voice command or vice versa (my Android phone already occasionally responds to a non-existent "OK Google").
The thing about the boring, old fashioned, traditional input methods is this: they work, by and large. Particularly in a working environment, if you want to replace an existing system then your replacement needs to be, at the very least, equally functional. In reality, it needs to offer actual, tangible to the user, improvements over the existing system in order overcome resistance to change.
