HP Envy 17 Leap Motion SE is the world's first laptop with built-in motion control

Built-in finger tracking tech means you never need to touch the optional touchscreen. Of course, you can if you want
HP Envy 17 Leap Motion SE

Adding a hefty dose of future cool to its latest laptop, HP's Envy 17 Leap Motion SE is the first laptop to feature a built-in Leap Motion sensor, letting you wave your commands and wiggle your wishes instead of using that stone age mouse and keyboard combo.

However, the laptop's design doesn't shout about its cutting-edge add-on – the Leap Motion sensor is visible only as a small black bar below the right hand side of the keyboard.

No touching

The Leap Motion sensor tracks fingers and thumbs in space above it, allowing for swooshy, mid-air control of onscreen items such as flipping through photos, scribbling doodles and manipulating 3D CAD models. The already tiny sensor has been slimmed down to a 3.5mm-thick bar that's activated with a simultaneous press of CTRL and space.

The screen itself is a 1920 x 1080 IPS affair (available in touch and non-touch configurations), and the laptop can be specced with up to 2TB of hard drive space, 16GB of RAM and an Intel Core i7 processor. Leap Motion's app store, called Airspace, comes pre-installed along with a handful of Leap Motion games and apps.

All that sci-fi hand-waving takes its toll on the battery – HP has already said that it's best used when plugged in for exactly this reason.

It's certainly a neater way of adding motion sensing to your laptop than attaching the separate sensor via USB, but if you do want to go that route you can buy one separately.
