Let the hive mind of Engadget get that for you.
"I own an iPhone 3G and I'm looking for a decent speaker / alarm clock for it. I am going to listen music in a mid-sized room, so I want nice quality speakers with solid bass. I also want to use it as an alarm clock, so it would be great if there is such a feature. The price can be low-mid to mid-high range. I was looking at the Klipsch iGroove SXT; it's powerful, slick and the reviews are good, but it doesn't have an alarm clock feature. It's no deal breaker if I can set it up from the iPhone, but I'm not sure. Thanks!"
Obviously someone has a good idea as the monitor must have some ability to watch the tablet-holders eye movements and be able to track them and correlate their movement to where the person is looking on the monitor. And THEN to interpret what the hand gestures on the tablet mean when associated with the item the eyes are resting on.
I hope that makes sense, and I don' t know why I am not using one right now.
