Airwriting may be the solution for your fat fingers
You may think the writing's on the wall and you may also think that that writing spells the future. But the future is in your hands. That is,[url=http://www.article-web.co.uk/category/discount-hermes-bags/]Discount Hermes Bags[/url], in the movement of your hands because very soon, you could be writing all your mobile texts and emails, with nothing more than hand gestures.
The man behind Airwriting as the technology is called is Christoph Amma, a computer scientist and PhD student Germany's Karlsruhe Institute of Technology (KIT).
Fitted out with a motion sensor, a Bluetooth wireless transmitter and a microcontroller,[url=http://www.masterclass-detailing.co.uk/category/ralph-lauren-polo-outlet/]Ralph Lauren Polo Outlet[/url], the glove isn't for climbing though it's a prototype that allows words and even sentences written in the air to be captured and turned into text on a computer.
Today, Amma's going to let me take the glove for a test run.
As he slips the glove onto my hand,[url=http://www.masterclass-detailing.co.uk/category/ralph-lauren-polo/]Ralph Lauren Polo[/url], he tells me the rules: I am only to write in English,[url=http://www.article-web.co.uk/category/hermes-handbags/]Hermes Handbags[/url], I have to use capital letters and I shouldn't wriggle my wrist around too much.
Amma then connects the circuit and the laptop on his desk springs into life.
I try to imagine I'm holding a piece of chalk and writing on an invisible blackboard,[url=http://www.article-web.co.uk/category/hermes-wallet/]Hermes Wallet[/url], and I spell out the word "Spectrum" (the name of DW's Science and Technology radio program) in midair.
Unfortunately, the word fails to appear on the computer screen it turns out I've picked a rare word that isn't in the system yet.
The airwriting system has an average error rate of 11 percent,[url=http://www.masterclass-detailing.co.uk/category/polo-outlet/]Polo Outlet[/url], which means that just over every tenth word is wrong. When adapted for the individual user,[url=http://www.article-web.co.uk/category/hermes-belts/]Hermes Belts[/url], though, this drops to around three percent.
"That's because everyone has their own block writing style even if they all write in block capitals. So if you adapt it for the individual user,[url=http://www.article-web.co.uk/category/hermes-birkin-bag/]Hermes Birkin Bag[/url], it gets a lot better,[url=http://www.article-web.co.uk/category/hermes-online-sale/]Hermes Online sale[/url]," says Amma, quickly adding that decreasing the error rate is something he's working on.
Amma slips on the glove himself, showing me how it still recognizes words even when he traces out tiny letters into his hand. "That way, it's not so distracting,[url=http://www.masterclass-detailing.co.uk/category/cheap-polo-shirts/]Cheap Polo Shirts[/url]," he says.
The airwriting system has been designed so it doesn't have to be turned on when the user wants to write.
It's capable of recognizing alphabet like patterns from among the millions of arm movements we make in a normal day.
Much of the research into gesture interfaces is focused on the recognition of single gestures assigned to a certain command such as opening an application on a smartphone by gesturing from right to left in front of the screen. But there's a limit to how many gestures people can or want to remember.
The strength of an alphabet based gesture interface is that people already know their ABCs.
But the question now is how to incorporate the gestures so they can control a phone.
KIT professor, Tanya Schultz, is part of the airwriting research team and Amma's supervisor. She says she can imagine airwriting being integrated with devices such Google glasses.
The integrated screen in the glasses "would give you an idea of what the phone is doing and whether the text you type is what you actually want to say," says Schultz.
