iPhone: Video Calling

FaceTime : Phone calls like you've never seen before.

People have been dreaming about video calling for decades. iPhone 4 makes it a reality. With the tap of a button, you can wave hello to your kids, share a smile from across the globe, or watch your best friend laugh at your stories — iPhone 4 to iPhone 4 or to the new iPod touch over

Wi-Fi. No other phone makes staying in touch this much fun.

One-tap simple.
FaceTime works right out of the box — no need to set up a special account or screen name. And using it is as easy as it gets. Let’s say you want to start a video call with your best friend. Just find her entry in your Contacts and tap the FaceTime button. Or maybe you’re already talking on a voice call with her, iPhone 4 to iPhone 4, and you want to switch to video. Just tap the FaceTime button on the screen. Either way, an invitation pops up on her screen asking if she wants to join you. When she accepts, the video call begins. It’s all perfectly seamless. And it works in both portrait and landscape modes.

Two cameras made for video calling.
iPhone 4 has two built-in cameras, one on the front above the display and one on the back next to the LED flash. The front camera has been tuned for FaceTime. It has just the right field of view and focal length to focus on your face at arm’s length. So it always presents you in the best possible light.

Share what you see with the back camera.
Imagine your sister is away at school and can’t make it to your son’s birthday. So you’re cheering her up with a FaceTime call. As the cupcakes come out, your son’s eyes light up, and you just have to share it. Tap a button, and before you can say, “Make a wish,” iPhone 4 switches to the back camera, and to the birthday boy's big moment. Another tap switches back to the front camera and to you. Simple, fast, and fun.

Word Lens by Questvisual : Instant translation app for iPhone

Instantly translate printed words from one language to another with your built-in video camera, in real time! 

Word Lens, an app that translates English text to and from Spanish on the fly, is a reminder of just how powerful apps can be. But how's it really work? It ain't perfect, but it's still pretty damn amazing.

I pointed Word Lens at all the Spanish I could find—the taco truck down the street, a Spanish-language newspaper, some signs on Google Street View and Google images—and I have to say that I was pretty amazed by how well it performed. Sure, sometimes words jump around like shapeshifters on crack, translating and retranslating rapidly as you jiggle the camera. And of course the translations are just done word by word, resulting in broken sentences that rarely have any semblance of correct syntax. But if you come into it with your expectations in check, Word Lens is still a terrific feat in mobile computing, even if its futuristic WOW quotient is, for now, a bit greater than its real world usefulness.

The app, which was released this morning by a company called QuestVisual, was two and half years in the making, according to founders Otavio Good and John DeWeese. Good admitted to TechCrunch that the "translation isn't perfect, but it gets the point across," and said that French, Italian, and Portuguese were likely candidates for future updates. But even without knowing what updates lie ahead for Word Lens, it's already an undeniably exciting taste of the future, one of the rare apps that transforms our smartphones into something entirely new.
