Giving a whole new meaning to the notion that your video game console is watching you, Sony PlayStation 3 might include technology that does just that. According to recent comments by a Sony executive, next-generation PlayStation consoles will include motion-sensor and camera hardware similar to Sony's EyeToy accessory for today's PlayStation 2. The technology would let users control games by using eye and finger movements, as well as gestures. The company is also working on technology for the console that will recognize facial expressions so that it can sense when you're sad or happy and react accordingly. However, that technology isn't expected to appear until PlayStation 4 hits stores, sometime in a distant future when man is at war with machines.
