HP Envy17 is the First Laptop With Leap Motion Sensor.

What is a leap motion sensor? It’ a small device that sits in front of your computer that allows you to move things with the power of hand movement. Measuring a tiny 0.5 inches in height and 1.2 inches in length this slick little device weighs just under 50 grams too. It sports a slick aluminium body and rubber top, connects via computer using a USB connection port and would not look out of place nestled among Apples well known range of devices. The Leap Motion Controller will be compatible with Windows 7 or 8 or Mac OS X 10.8 Mountain Lion (minimum requirements: AMD Phenom™ II or Intel® Core™ i3, i5 or i7 processor; 2GB RAM; USB 2.0 port; Internet connection).
HP Senior Vice President Ron Coughlin said in a statement;
“We are excited to be the first to embed Leap Motion’s technology in a PC. Our collaboration with Leap Motion is just one example of how HP is innovating and defining the next generation computing experience.”
