Use your webcam as face gesture

News from opera Labs :  Opera we are always working on new ways to make your browsing faster. Eight years ago we introduced Mouse Gestures as a way to speed up your interaction with the browser and focus on what’s important: the content you’re looking at. We didn’t stop there, in 2005 we introduced Voice Navigation on the desktop and more recently we have worked with Nintendo to create a browser that takes full advantage of the “Wiimote” and later, the touchscreen in the DSi.

Looking ahead, we recognize the future importance of touch interfaces, but we believe that there is another input device that is already present in most new computers and it’s ready to enable a whole new way of user-interaction: the webcam.
Today we introduce Face Gestures, a revolutionary technology designed to make interacting with your browser easier and simpler on computers with cameras. Face Gestures lets you perform frequent browsing operations with natural and easy to make face gestures. By using an internal technology dubbed Face Observation Opera Language, we are able to recognize pre-determined facial expressions and match them to commands on the Opera browser.
You can try Face Gestures today by downloading the latest Opera 10 alpha snapshot or check out the video below to learn more.



Setting up Face Gestures

To enable Face Gestures press F8. You will hear a beeping sound as soon as Opera finishes calibrating your passive facial expression. Please don’t close your eyes, move your head or make any facial expressions while Face Gestures is calibrating.

Look at me

Among many others, the following gestures are currently included:
Initial stance
Relaxed expression
Back
Left wink
Forward
Right wink
New Tab
Double wink
Reload
Shake head
Go to Home Page
Roll eyes / Fake smile
Scroll Up
Raise eyebrows
Scroll Down
Frown eyebrows
Zoom In
Suck cheeks
Zoom Out
Puff cheeks
Bookmark Page
Lick up
Open Speed Dial
Waggle tongue
As always, we encourage all feedback and suggestions you may have. Please upload your gestures suggestions as a response to the above video in YouTube.

Security Considerations

No personal information or images are sent back to Opera when Face Gestures is enabled, so don’t worry about how you look.

Known Issues

As with any beta release there are some known issues with the current version of Face Gestures. Please read below before reporting a bug.

  • Beards and hair styles

    Face Gestures is compatible with most types of facial hair and haircuts. But if your face is covered with more than 25% of facial hair, recognition errors may occur. Please note that handlebars and goatees are compatible independently but if combined recognition will decrease. At the moment soul-patches crashes the browser and it refuses to relaunch, we are looking into this problem. Bushmen beards and emo haircuts are not supported.

  • Adult Web sites

    Users visiting Web sites that contain adult content sometimes make unconscious facial expressions. If Opera keeps opening Speed Dial and Zooming In and Out, please be aware that this not a bug. It may be useful to disable Face Gestures for a better experience. Also remember that wiping your cache is recommend after visiting untrusted websites.

  • Financial Web sites

    For compatibility reasons Face Gestures auto-detects financial news services and disables itself. The current version of the recognition software is unable to adapt fast enough to the sudden change in the users expression map. As soon as the new version is available you will be prompted to installstimulus_package.patch.

Top 10 Open Source PBX Software.

PBX (Private Branch Exchange) is a small telephone switch that is used to establish connections among the internal telephones of a private organization. PBX reduces the overall cost of telephony in a company by reducing the total number of telephone lines they need to lease from the telephone company. Without a PBX a company needs to lease one telephone line for every employee with a telephone. The company only needs to lease as many lines from the telephone company as the telephone company as maximum number of employees that will be making outside calls at one time. It is nearly 10% of the number of extensions. In a PBX system, every telephone is wired to the PBX. When an employee takes the receiver off hook and dials the outside access code, the PBX connects the employee to an outside line. The enterprise-class PBX including directory-based voicemail, conference calling, integrated messaging, interactive voice response (IVR), three-way calling, caller ID, and call queues....

The evolution of hard drives and Storage

The punch card A punch card was once the basis for digital information used for computer programs and data storage. They were widely used throughout the first half of the 20 th   century in processing machines to input data and to store it. Punch cards could be fed into the first commercial computer, IBM 305 system, which then stored the data on hard disks. IBM 350 disk storage unit The 350 Disk Storage System was a major component of the IBM 305 RAMAC (Random Access Method of Accounting and Control) system, which was introduced in September 1956. It consisted of 40 platters and a dual read/write head on a single arm that moved up and down the stack of magnetic disk platters. Those 40 platters stored a whopping (for the time) 5MB of data.
