Facebook testing ‘sound alert system’

by vinayak mathur

Social networking giant Facebook is reportedly testing a new feature that emits a ping sound when a user writes on your Timeline, sends you a message or invites you to an event.

“We are currently testing a sound with notifications,” a Facebook spokesperson said.

“It’s only testing with a small percentage of people and it can be controlled from the Account Settings page,” the spokesperson added.

According to Mashable, the test was first spotted by a VentureBeat reporter whose profile page was among the test audience.

The writer posted a video and noted he “hates” it already.

We can assume many others will not be pleased to hear a constant stream of sound alerts, the report said.

Nintendo DS-controlled navigation system announced by toyota

by vinayak mathur

Toyota has unveiled a new tool for Japan that lets passengers use a Nintendo DS to control a vehicle’s navigation system. Called Kuruma de DS, the tool was recently shown off at a press conference in Tokyo, and it’s expected to launch on June 1st.

It works with Toyota’s new Smart Navi system, and consists of a DS cartridge that can connect to the system via Bluetooth. When the two are paired up the handheld can be used to do things like view maps, update destinations, and check on the vehicle’s speed.

It also includes Nintendo’s trademark bubbly presentation complete with Miis, though the asking price is a little steep — the navigation unit will run you ¥206,850 ($2,575), while the DS cartridge itself costs ¥7,329 ($90). For now it looks like the two will only be available in Japan, where the DS and its successor are both incredibly popular.

Google planning to launch a blog commenting system ?

by vinayak mathur

Google is preparing to launch a blog commenting system similar to the one offered by Facebook according to Saudi Arabian site Tech-WD, which jibes with the rumors that first surfaced in WebProNews in October last year. The system was supposedly discussed along with a number of other unannounced features at the G-Saudi Arabia Google conference in Jeddah, and would tie in with the rest of your Google account. Comments would be indexed by Google Social, the same service that crawls tweets and Facebook for Google’s search service.

The introduction of a comments system would be yet another way for Google to take a role in your connected life. For the company, the ability to tie in your social activity from around the web into your Google+ profile also has the potential to reignite interest in the social network should the system become widely adopted. However, it could also easily become another cause for concern for the privacy conscious.

Surveillance Camera System Searches Through 36 Million Faces In One Second

by vinayak mathur

This surveillance camera system can search through data on 36 million faces in one second. Developed by Hitachi Kokusai Electric, the system can automatically detect a face from either surveillance footage or a regular photo, and search for it.

The search results are displayed immediately, showing thumbnail images of potential candidates. When a thumbnail is selected, the associated recorded surveillance footage can be viewed, so users can quickly review the persons actions before and after the image was taken.

With this system, it’s assumed that faces are turning within around 30 degrees in the horizontal and vertical directions from the camera, and the faces are at least 40 x 40 pixels in size.

Representative from Hitachi Kokusai Electric stated :-

“This high speed is achieved by detecting faces through image recognition when the footage from the camera is recorded, and also by grouping similar faces.”

“We think this system is suitable for customers that have a relatively large-scale surveillance system, such as railways, power companies, law enforcement, and large stores.”

“We plan to release this system next fiscal year. We’ll be handling each project individually”

Futuristic US Navy railgun with 220-mile range closer to reality

by vinayak mathur

 

Raytheon Company (NYSE: RTN) has been awarded a $10 million contract from Naval Sea Systems Command to develop a pulsed power system that will enable projectiles to reach great distances without the use of an explosive charge or rocket motor.

 

The contract for the preliminary design of a Pulse Forming Network (PFN) is part of a larger effort by the U.S. Navy to develop a multimission weapon system for use on naval warships to defend and attack with pinpoint accuracy.

Under the contract, Raytheon will provide the research and development of an advanced Integrated Power Systems power load module that may be used for PFNs to power future lasers, railguns or radars.

“This new system will dramatically change how US Navy defends itself and engages enemies while at sea,” said Joe Biondi, vice president of Advanced Technology for Raytheon’s Integrated Defense Systems business. “We have the expertise to design and build a solution that provides our warfighters with a decisive advantage over a multitude of current and emerging threats.”

The PFN is a large power system providing the electromagnetic energy for the railgun projectile, which will travel up to 220 miles in less than six minutes and exit the atmosphere before hitting its target at a velocity of 5,000 feet per second.

 

Turn Any Surface Into a Gestural Musical Interface

by vinayak mathur

Bruno Zamborlin collaborated with Norbert Schnell to use a contact microphone connected to a system that processes sound in real time to turn any rigid surface into a touch interface. There’s no way to explain it adequately in words, so just watch the video:

In Zamborlin’s own words, here’s how the magic is accomplished:

Through gesture recognition techniques we detect different kind of fingers-touch and associate them with different sounds. In the video we used two different audio synthesis techniques:
- physic modelling, which consists in generating the sound by simulating physical laws;
- concatenative synthesis (audio mosaicing), in which the sound of the contact microphone is associated with its closest frame present in a sound database.

To put it another way, the system is transforming the vibrations transmitted from touch through a rigid body into waveforms that a computer can, in real time, recognize and either transmute into audible sound or use as a triggering mechanism for other sounds.

It’s an ingenious approach, especially because Zamborlin has made the system clever enough to recognize the sound of particular gestures, so that the interface can accomplish more than just triggering actions when it “hears” a tap.

So will touch interfaces of the future rely on sounds as well as capacitance? Perhaps sound would be a cheaper, more-durable option for certain kinds of interfaces, making touch interactions all the more ubiquitous

US Army Hummingbird drone gets 1.8 gigapixel camera

by vinayak mathur

Starting in July of 2012, the United States Army will deploy three Boeing A160 Hummingbird drones to Afghanistan as part of a one-year trial program. Unlike the Predator drones already in combat, the A160 is a rotor-based aircraft capable of vertical take-offs and landings.

What’s more, the craft will be affixed with the DARPA-developed ARGUS-IS imaging system – which boasts a 1.8 gigapixel camera the Army says can “track people and vehicles from altitudes above 20,000 feet.”

The A160 Hummingbird platform will provide the Army with the ability and flexibility to: take off and land without a runway; fly for twelve hours or more without refueling; and monitor up to 65 enemies of the State simultaneously.

Test flights of the unmanned chopper are scheduled for early 2012 in Arizona, but residents hoping to get a glimpse of the A160 in action best have great eyesight the ARGUS-IS system can see targets from almost 25-miles down range.

Transparent kayak lets you see more

by vinayak mathur

The Molokini is an all-transparent two-passenger kayak made out of the same durable polycarbonate material used in the production of bulletproof glass and fighter jet canopies.

It comes equipped with an anodized aluminum internal frame system, dual flotation bladders and a three-quart water bailer. The Molokini features a removable lightweight anodized aluminum frame system, allowing the user to minimize space consumption, thus making transporting and storage of multiple units easy and convenient.

This model is recommend for areas that experience calm ocean conditions. New retractable skeg system included in the standard version improves tracking, a feature especially convenient for long distance paddling.

Tests performed on the island of Oahu, Hawaii, have proven that the visibility on a sunny day and during non-turbulent water conditions can yield views to depths of 75 ft plus for the exploration of new worlds waiting to be discovered.

Ford’s New Lane Keeping Technology

Ford is introducing new lane keeping technologies, including a system that can help detect drowsy drivers, to help them stay alert and in their lane, system to launch in early 2012 on the Ford Explorer.

The technology’s Driver Alert System monitors the vehicle’s lane position and can notify a driver of signs of inattentiveness with a coffee cup warning light that appears on the dashboard instrument cluster

More than 40 percent of Americans say they have fallen asleep or nodded off while driving, according to a survey conducted by the AAA Foundation for Traffic Safety

The Lane Keeping Alert function warns the driver by vibrating the steering wheel and sounding a warning chime, while the Lane Keeping Aid function warns the driver by applying torque at the steering wheel to direct the vehicle back into the lane.

Hack Your TouchPad to Run Android, Win a Prize

by Shipra

TouchPad1

After HP announced it would discontinue production of its TouchPad tablet last week, it looked like early HP tablet adopters spent $500 on a dud. If you’re an enterprising software hacker, however, there could be an opportunity to make your money back — and then some.A hardware-modification web site is offering a $1,500 cash bounty for the first person to successfully port a full version of the Android operating system over to HP’s TouchPad.

Hacknmod.com offers a tiered bounty system for would-be TouchPad hackers: Just getting Android to run on the TouchPad without taking full advantage of the tablet’s hardware will win you a cool $450. But the more you’re able to integrate the system software into the device, the more cash you’ll earn. Get the Wi-Fi, multitouch capability, audio and camera up and running, and you’ll add another $1,050 to the pot.

While the bounty is characteristic of the Android-modding crowd which basically wants to slap Android onto anything with a circuit board and touch screen, it’s also an admirable effort to breathe new life into a dying piece of hardware. After reports of dismal sales and third-party retailers sitting on hundreds of thousands of unsold TouchPads, HP decided to kill production after a mere 49 days on the market.

It was bad news for current TouchPad owners. No more HP hardware gives little incentive for webOS app developers to continue producing applications for the platform. In turn, TouchPad owners miss out on the latest popular applications to come to mobile devices. And of course, it gives potential customers no incentive to buy the remaining TouchPads retailers have in stock, costing HP and retail stores hundreds of millions of dollars. Everyone loses. But if the porting plans work, it could mean bringing a slew of Android apps over to HP’s tablet. If the TouchPad can be made capable of running thousands of Android apps, the device may not be obsolete.

This isn’t the first time the Android-modification community tried to port the operating system over to non-Android devices. Android modders have run the operating system on Barnes And Noble’s Nook Color e-reader, certain Nokia smartphones and even an iPhone. If you don’t want to go it alone, Android-modification-enthusiast site RootzWiki created a team specifically to work on porting Android over to the TouchPad, christened the TouchDroid team. The plan is to get Android version 2.3 (Gingerbread) up and running, then install a version of CyanogenMod, the most popular modification software available for Android devices. Eventually, the team wants to get Android 3.0 (Honeycomb) onto the TouchPad, Google’s tablet-optimized version of the software. The coders will post updates to a thread on a message board devoted to Android development on the TouchPad.All of the Android hacking mania raises the question: If all you want is an Android tablet, why not just go out and buy one?First, you may be able to get a TouchPad for even less than you would a proper Android tablet. HP, Best Buy and some U.K. retailers slashed prices on their TouchPad inventories over the weekend, dropping the price as low as $100. Sales skyrocketed, and the TouchPad reached the top of the electronics sales charts on Amazon.com. Android tablets that boast hardware similar to the TouchPad average $400 to $500. Second, the future of webOS is unclear. HP says it will continue to support the operating system despite discontinuing its tablet, but that doesn’t necessarily mean we’ll see tablet-optimized updates to webOS in the future. And of course, HP could sell off the operating system for its patents to a competitor like Google or Apple, which would all but secure the system’s demise.Most important, hackers hack because they can. Android was built using open source software principles, a favorite of the modification community that codes for the fun of it. If you propose the challenge of running an operating system on a piece of foreign hardware, expect the DIY community to take you up on it.
