Some of the gizmos hitting the headlines in the world of technology have been honoured for their innovation at the Consumer Electronics Show, which starts on Thursday in Las Vegas.
eMagin Z800 3DVisor
Video game makers often talk about creating immersive games where players can lose themselves in virtual worlds.
Lose yourself in a virtual world
A company called eMagin believes the answer lies not so much in the games, but in how they are viewed.
It has come up with a 3D visor that uses two micro displays to create a stereo vision of a game.
The headset has a tracking system using gyroscopes that lets players look around a game by moving the head from side to side.
"It is a much more immersive experience than looking at a big screen," said eMagin's Bruce Ridley.
"Most PC games will work with it," he said, adding it would also work on the new Microsoft Xbox 360.
The company is talking to all the major console makers about the headset.
"Nintendo has even purchased some," said Mr Ridley.
The company has been selling the headset via its website since July.
Stargazers will find answers with this celestial gadget
GPS technology is normally associated with satellite navigation systems.
But others are looking at innovative ways of tapping into the potential of GPS.
Celestron has taken its background in making telescopes, to come up with a handheld gizmo that can identify thousands of objects in the sky.
The SkyScout uses GPS technology to work out the location of celestial objects that can be seen with the naked eye and find out what it is you are looking out.
"It is like a planetarium except that you are actually looking at the stars," said Celestron's Jennifer Adams.
The unit has a built-in database with some 6,000 entries. But it can be updated via its USB port or the SD memory card slot.
"Say there is a new comet discovered, you can download the information from our website," she said.
The product has been in development for three years and is expected to hit the shops in the US in March.
RaySat SpeedRay 3000
Turn any vehicle into a wi-fi hotspot
The idea of an internet hotspot on wheels might sound far-fetched. But one of the products on show at CES can turn any vehicle into a wi-fi zone.
The SpeedRay 3000 by RaySat is a round, low profile antenna designed to go on the roof of a vehicle and access satellite TV and broadband.
The system is said to provide an always-on connection on the move, using GPS technology to track the location of a satellite. Inside, the antenna rotates and tilts to adjust its position.
"As long as you have line of sight to the satellite, you are fine," said RaySat's Lynette Henley, adding that the signal would drop somewhere like New York because of the skyscrapers.
People who own motor homes are seen as the main audience for the system, as well as the emergency services and the military.
But communication on the go comes at a high price, with the antenna costing $7,000, together with monthly subscription costs. It is due to go on sale in the US in the summer.
Logitech G5 laser mouse
Mouse that offers more control for gamers
In professional video game contests, where thousands of dollars are up for grabs, having the right equipment is crucial.
For hardcore PC gamers, the level of control offered by a computer mouse can mean the difference between success and failure.
"Gamers are our hardest critics," said Logitech's Kate Brinks.
"People who buy our mice take them apart to take parts out or put in extra weight, and this voids the warranty."
Logitech has tried to address some of these concerns by developing a mouse with its own weight-tuning internal system.
The G5 laser mouse comes with 16 miniature weights, eight weighing 1.7 grams and eight weighing 4.5 grams.
Eight of these can be placed inside the mouse to customise the weight and balance.
Logitech hopes this will satisfy gamers who are looking for a mouse that feels exactly as they like.
