Here is a small demo of what was avalible to have a play with at this year's International Consumer Electronics Show:

Game-controller glove - Iron Will Innovations demonstrated a futuristic looking black and silver glove that replaces a keyboard and lets users control games by touching their fingers together instead. Called the Peregrine, the glove includes five sensors on each finger that replace different keystrokes when touched to the glove's thumb.

The glove and plugs into a computer's USB port. The Peregrine should be in stores for US$150 by the summer, though the company is taking pre-orders online for US$20 less.

Wireless charging -Powerpack, a battery that replaces the one that comes with your cell phone and lets you charge your handset by placing it on the mat - no other attachments needed. Powerpacks that are compatible with dozens of handsets are expected to be available for US$40 in May 2010.

3-D camera - The big push from TV makers this year is for sets that show 3-D in the home. Fujifilm, betting that people will want to shoot their own 3-D movies and photos as well, is also selling a digital camera with two lenses, set apart as if they are human eyes.

The screen on the back of the Finepix Real 3D W1 presents, if you squint a little bit, a 3-D image using a glasses-free technology similar to the old 3-D postcards. The 3-D camera is available now for US$599, and a 3-D photo frame sells separately for US$499.

3-D colour printing - Shapeways has been offering 3-D printing for a few years, taking data files and turning them into sculptures with the help of a machine that lays down successive layers of a plaster-like material.

At the show, the Dutch company announced that they're now offering sculptures in full colour. The dyes are impregnated into the material as it's being built up. The cost: US$16.22 per cubic inch.

Mopping robot - Cleaning robots? The vacuuming Roomba robots will get competition this September from the Mint, a square robot that has a pad for a dry or wet Swiffer-type cleaning cloth. Evolution Robotics says the price will be around US$200 to US$250.
