I really LOATHE these voice activated command sets -- we have enough "noisy intrusions" already with people screaming away at the top of their voices on mobile phones in public areas or even in open plan offices - people just forget any sort of decent consideration of other people and reasonable etiquette once they start squawking on Mobile phones.
Just think how much worse it's going to be if you get a whole slew of people screaming at their computers "Appontment for Lunch next thur at 13.30" or whatever.
Even on those automated phone systems - they've managed to add this to the torture list of using these -- for example when you phone up say a Bank about a mortgage - you get one of these automated robots requesting you to answer a whole slew of questions like "Is this Your Mortgage" etc. The previous sytem you'd just enter the number and things would progress normally. Why should I have to tell a Robot "YES THIS IS MY MORTGAGE or NO IT'S SOMEONE ELSE's at the top of my voice because the Robot can't understand the diction correctly.
Vocal stuff is fine if say one is partially sighted or handicapped in other ways so that's the only convenient input but for the rest of us - we should be making things QUIETER not adding to the general cacophony of public places and open plan offices.
Besides I might not want people to know I'm making an appointment for Lunch at 13.30 on Thur to use the example given.
I LIKE technology and genuine improvements --I just don't like the whole idea though of this cortana stuff - at least in its proposed form.
