OS X Mavericks Taps Ambient Light Sensors to Detect Motion and Prevent System Sleep

That's a bug (or "limitation" if you want to be kind) in the app that's doing the downloading/encoding.
After I seen this article, I decided to test it out a bit. I set mine to sleep after 1 minute. Just sitting and looking at the screen without touching anything kept it awake. I wasn't moving around a whole lot. I was trying to stay as still as possible, but it picks up the slightest movement, which is good. I sat for about 3 minutes and the screen stayed on. I stood up and walked off to the side, out of view from the sensor but where I could still see the screen. It dimmed after 10 seconds, and went to sleep after 20. This means the timer does not reset and begin counting after it stops sensing movement. If you don't use the computer at all after your time is reached, it won't shut off until it stops sensing you sitting there. Basically, the timer starts counting after the last physical interaction with the computer, but won't begin sleep mode until you walk away. Very neat and well designed.
These aren't automatic solutions. I wan't it to work automagically.
PS. I've been using caffeine for years.
Doesn't seem to work on my macbook pro 2012. I have auto adjust display set to on.

When run from Terminal, this script with show the idle counter.

TouchID keyboard, never thought of that idea. That would be pretty amazing, instead of constantly typing in your user password. Adding the option of a security code/password as in iOS 7 TouchID would allow others to use your system as well (should you wish).
I was reading this thread in case anyone else asked about Apple LED Thunderbolt/Cinema LCD's working with this feature on a Mac Pro or any Mac as a secondary display. Do these displays have light sensors in addition to the camera's? How would a MacBook or iMac with a second display utilize this feature?
Invasive or Innovative?
OS Universe coming this year, 2083, uses advanced Wi-Fi signal scanners and receivers to detect your brain electromagnetic patterns and determines the area of the brain with the most activity in order to activate the necessary power capacity, measure intelligence - with recommendations of mental upgrades and exercises to boost it, recommend other appropriate heath suggestions, erotic visuals tailored to your exact sexual stimulation preferences along with determined dietary needs. Yes, you can manager power consumption on your own but we like you invade your privacy and know you are there and what you are thinking so we can do that for you! The NSA has funded most of this valuable research.

Sleep Issues

I actually use a combination of both. I have Caffeine for when I want to keep the display on or when I'm running on battery. I have NoSleep set so I can shut the lid when I'm plugged in and keep the machine on.
I could use NoSleep for everything, but manually toggling NoSleep also changes the setting, so I would have to open it up every time to reconfigure it. Caffeine unfortunately does not prevent sleep when the lid is closed.
Nosleep has to be one of my favourite apps. It's also great for leaving my macbook running with the lid closed.
I've never seen this on an iMac or Macbook - are you sure your movement isn't vibrating the mouse a tiny bit?
This is a pretty neat little feature, as the ambient sensors are presumably checking every so often already in order to detect lights being switched off, curtains closed etc., so all Mavericks needs to do is process that a little further to detect sharp changes most likely to be someone moving
clever stuff!
I assume it'll require a Mac with built-in display; anyone know if it will work with Thunderbolt displays too?

You can always put the computer to sleep manually. Apple menu > Sleep.

If you're doing anything that time-consuming and assuming it would be processor-intensive, that probably means your Mac is plugged into the wall. Therefore, you simply adjust your "Power Adapter" Power Saver settings accordingly, which are separate from the "Battery" settings, if applicable to your machine.
It's easy to throw blame when you don't know what you're talking about, eh?
The negative comments in here are ridiculous. There are about 10 different ways to either put your Mac to sleep manually or keep it awake manually. That has nothing to do with this feature. People try to downplay anything. If you're done with your laptop, close the friggin' lid... not wonder "OMG... I just walked by it and now I've prolonged the time for it to sleep again! Oh lawdy... my first world problems have struck again. How will I acquire the skills or even find the capacity to put this newfangled contraption to sleep? There is no other way than to go nowhere near the Mac."
On my new late-2013 iMac (which shipped with 10.8.4) I no longer have an option for computer sleep, only display sleep. All I can do is choose to have my computer sleep when my display sleeps - no longer independent. I'm quite puzzled about this change. Is this normal? I checked a late-2013 model in the store (which had 10.9) and it showed the same panel in Energy preferences as mine does.
