Xbox One's Kinect sensor is capable of an extraordinary level of fidelity and resolution, down to recognising facial expressions. Theodor Diea, international product manager for Just Dance 2014, explained to us that Ubisoft have actually experimented with a range of ways to take advantage of this enhanced accuracy - including some bizarre achievement rewards.
"Essentially the leap you see in technology is like the PS1 to PS2, like, for graphics," Diea told Dealspwn.com at a preview event earlier this year. "You have that same kind of difference in what Kinect can do on the Xbox 360 and Xbox One. It's leaps and bounds above what it could do before."
"We're able to track up to six players with the Xbox One, so we have six different unique choreographies. It lets us do things like getting our players to make a human pyramid, we've been exploring achievements specifically with the camera. Nothing's set yet, we were trying different things out, but we've had tests work out pretty well where, like, you get an achievement for smiling when you see your first Autodance. You can track emotions with that."
"We've got another one we've been playing around with: complete a routine with five stars and have your eyes closed the entire time."
I asked whether expression recognition could be more heavily factored into games or even collated as useful metrics, but Diea suggested that the human side of the equation is too unpredictable for that.
"The problem with emotions, reading emotions with cameras when you do tracking, is that some people have a great time with a frown on their face. It's really hard to analyse that because it involves different expressions on faces... it doesn't always match up."
He's not wrong. Speaking of people who "have a great time with a frown on their face" while playing Just Dance 2014, let's post this just once more for the road...
