Dial a phone number using in-air gestures

Gesture-recognition interfaces for cell phones are closer to reality with technology from the University of Tokyo that lets you operate your phone or mobile device without laying a finger on it.

Researchers at the Ishikawa Komuro Laboratory have created a "vision-based input interface for mobile devices" through which users can type words by pointing in the air. There's no dialing demo in the video below, though that would presumably be just as simple.

Unlike gestural interfaces such as MIT's SixthSense, the system does not require special colored finger markings to track gestures.

Want to see Google's new phone on YouTube?

Google won't officially unveil its Nexus One smartphone until Tuesday, when it has scheduled an Android Press Gathering. There are plenty of descriptions and images of the phone floating around the Web, though--a result of Google's decision to "dogfood" the device with employees.

And now, some video. Wednesday, a 10-minute clip of what appears to be someone taking the phone through its paces popped up on the Web. There's no sound, and the device appears to be configured for French speakers, so if you're an American with a short attention span, I'm not … Read more

Tivit streams Mobile DTV to your iPhone, BlackBerry, and PC

One of the big tech stories of 2009 was the transition of the U.S. broadcast TV standard from analog (NTSC) to digital (ATSC). But while ATSC broadcasts offer crystal clear high-def images, they have at least one drawback: unlike analog broadcasts, digital TV is tough to receive if you're on the move. That means that even "portable" digital TVs have to be locked down with a carefully pointed antenna before you can really watch them.

Thankfully, Mobile DTV is aiming to change that. The new standard is optimized for small screens and access on the move. … Read more

What's the one app you can't live without?

Before 1999, a BlackBerry was just the name of a fruit.

And a few years ago, Apple launched a touch-screen smartphone that caught the entire mobile industry napping.

Soon after, there came an explosion of mobile-phone applications. From Facebook to Twitter and Maps to VoIP, there's an app for almost every imaginable activity. The phrase from Apple's iPhone marketing team, "There's an app for that," aptly describes what we've witnessed in the past year.

Now, what's the one application you can't live without on your smartphone? Tell us in Talkback.

Discover Spotlight searches--David's iPhone tip of the week

Spotlight, an advanced utility for searching, migrated from the Mac to the iPhone and iPod Touch, and we should all be grateful for that since it is quite useful. Spotlight also happens to be one of my favorite iPhone features, and this week I'd like to share some of my favorite tips about it.

Access Spotlight

You access Spotlight from the iPhone Home screen by pressing the Home button once when you are on the first Home screen, or by simply swiping left while that screen is displayed.

If you are on a different screen, press the Home key … Read more

So you got an iPhone, now what?

If an iPhone awaited you under the tree this Christmas, we understand if you're a bit excited. Reception woes aside, the iPhone is a remarkable device in many respects. It offers a great multimedia experience, efficient e-mail integration, a spiffy Web browser, and thousands of third-party apps that do everything from helping you choose a seat on an airplane to guiding your way to the airport. And now that it has multimedia messaging, we're no longer waiting for any basic cell phone features. Granted, those pesky network issues won't go away soon, but you may get lucky and have no problems. And even if you do, at least you have a shiny new gadget, right?

If you've never used an iPhone before, getting started can be a bit overwhelming. With so many apps and accessories available, it's not easy to separate the wheat from the chaff. And even if you're a veteran iPhone user who's graduating to the newest model, exercising discretion, particularly when purchasing apps, is wise. You might say, "It's just 99 cents!" but 99 cents multiplied scores of times can result in a hefty iTunes bill.… Read more

iPhone + robot marimba player = instant band

Tired of Guitar Hero? Try jamming with your iPhone or iPod Touch and Shimon, an autonomous, marimba-playing, octopus-armed hipster robot.

Gil Weinberg, director of music technology at Georgia Tech, is developing Shimon as a socially dynamic band mate. He says the robot "listens like a human and improvises like a machine" thanks to complex algorithms that allow it to perceive and improvise a groove.

Weinberg is also behind ZOOZBeat, an app that turns your iPhone into an instrument and sequencer, letting you remix and loop your own music by shaking, tilting, and otherwise getting down with it. Beats come bundled with the app, but you can also download packs with vocals, hooks, and instruments.

If there aren't iPhone-only bands out there already, ZOOZBeat will probably start a trend. But as I mentioned in an earlier post about the exciting new Eigenharp, electronic music concerts can benefit from a more dynamic physical performance, and that's where Shimon, with its bobbing cyclops head, comes in.

As the vid after the jump shows, Shimon can take your ZOOZ loop with a Wi-Fi flick and run with it. Here, it repeats and improvises on a jazzy loop, playing in a variety of styles resembling jazz greats like John Coltrane or Thelonius Monk. … Read more
