PEN SPINNING

Pen spinning or pen twirling is a form of object manipulation that involves the deft manipulation of a writing instrument with one's hands. Although it is often considered a form of self-entertainment (usually in a school/office setting), multinational competitions and meetings are sometimes held.[1] It is a form of contact juggling.

Pen spinning is known as "pen mawashi" (compare for example Mawashi geri, "round-kick") or, more disparagingly, "rōnin mawashi" "college student spinning" in Japan where the pastime has been popular since at least the 1970s, and where the Pen Spinning Association Japan is now dedicated to promoting the aspiring art form. While its origins remain unclear, pen-twirling is quickly gaining international popularity through on-line video sharing and forums. According to Masaki Tsukada, chairman of the Japanese pen spinners, pen spinning now has dedicated movements in South Korea and the United States.

Here are Some examples of future of mobile technology

















13 future mobile technologies that will change your life




Disruption 1: Mobile WiMax Sprint Nextel Corp. said it will launch its mobile Xohm WiMax network commercially in a handful of cities next spring with more cities added throughout the year and 2009. It has the potential to be a game-changer, some experts say.
"If you're looking to 2009 or 2010, WiMax will be somewhat revolutionary in terms of wireless broadband," said Brian Clark, a partner with M/C Venture Partners in Boston. "It starts to offer a DSL-level of [wireless] service."
Sprint claims that Xohm's typical (as opposed to peak) speeds will be in the 2Mbit/sec. to 4Mbit/sec. range. And while Sprint hasn't yet provided pricing details, it has said its WiMax offering will be priced similarly to DSL and cable access, which is significantly cheaper than 3G. Even more radically, at least for a company best known as a cellular operator, Sprint won't demand long-term contracts but, rather, will use a subscription model.
Verizon Wireless said it will deploy a competing technology called LTE (long-term evolution), which will have similar speeds to Sprint's Xohm network. However, most observers believe that LTE and similar technologies deployed by other carriers won't start to be available until at least 2011. By that time, proponents claim second-generation mobile WiMax will offer speeds potentially as high as 1Gbit/sec.
Why it's important: Most of the other disruptive technologies discussed here require fast, affordable wireless access.


Disruption 2: Multihop relay networksSome researchers and futurists believe that multihop relay networks will eventually supplant technologies such as WiMax and LTE. With these networks, wireless signals will route themselves through a series of access points. Like the Internet itself, the route that the data takes is variable, depending on conditions.
"The network will find the best route and the best transmission mode," said Wen Tong, director of Nortel Networks' wireless technology laboratory. "I see initial deployment in three years."
A variant of the multihop relay network called ad hoc networks could come even later. With this technology, data would be relayed through, among other things, devices themselves. In other words, your phone will also be a movable access point.
"The defining quality of the ad hoc network is that it has no infrastructure," said Anthony Ephremides, a professor of electrical and computer engineering at the University of Maryland. "I'd guess it'll be [ready] in a five-to-10-year time frame."
Why it's important: These networks will extend network access to where none exists without building a lot of infrastructure. Because there is little infrastructure, the networks can withstand catastrophe. That is why, Ephremides said, the military is sponsoring a lot of research into ad hoc networks.
What could hold it back: This technology is still very much in the research phase, particularly ad hoc networks. A variety of issues, not the least of which is security, have yet to be resolved.
Disruptions 3 and 4: Femtocells and fixed-mobile convergenceBoth these technologies enable you to have one phone and one phone number with which you can communicate from virtually anywhere.
Sprint has started offering femtocells on a trial basis." src="http://www.blogger.com/common/images/site/features/2007/102007/femtocell1.jpg" width=160 height=242>Sprint has started offering femtocells on a trial basis.A femtocell looks a bit like a Wi-Fi router but performs the same function in the home or office as cellular base stations that sit in brick buildings at the base of cell towers. That is, they communicate directly with your cell phone and carry the signal to the larger network via a broadband line such as DSL or cable.
"Carriers will offer femtocells the way cable operators offer cable modems," said Paul Callahan, vice president of business development at femtocell vendor Airvana Inc. "They'll give you five bars in your home."
That means you'll be able to ditch your landline and use your cell phone everywhere. Sprint is offering femtocells, on a trial basis, to customers in Denver and Indianapolis and is charging $15 a month for individuals or $30 for a family. Subscribers can then make as many local and national calls as they want.


T-Mobile USA launched its http://www.computerworld.com/action/article.do?command=viewArticleBasic&articleId=9025820 program last June, which requires a cell phone that supports both Wi-Fi and regular cellular access. Built into the phone is software that enables you, for example, to walk into your home or office while talking on the cellular network and have the call seamlessly switch to voice-over-IP on the Wi-Fi network. You also need a compliant Wi-Fi router.
As with femtocells, fixed-mobile convergence allows you to lose your landline. T-Mobile is charging about $30 a month for unlimited local and national calls. The program has met with generally good reviews.
Why it's important: Having a single phone and a single phone number will be a great convenience and money saver. Also, some of the disruptive applications discussed later depend on the ability to track your availability no matter where you are. Using only a cell phone makes this more possible.
What could hold it back: To some extent, these technologies will duke it out against each other. That will take time to sort out.
Better devices
With faster, more ubiquitous access, devices can start to radically change.
"Imagine a Bluetooth headset in your ear but that's the phone," said Dan Burrus, CEO of Burrus Research Inc. and author of the book Technotrends. "And it will continue to get smaller from there until it's implanted in your ear. You ask for whatever you need [with your voice] and it will tell you the answers."
However, smaller, more powerful phones themselves will be the end result of several enabling disruptions, Burrus and the other experts agree. These disruptions may seem relatively minor but, added together, they will result in the phones and applications of tomorrow.
Disruption 5: Miniscule, less power-hungry mobile chipsChip vendors have been talking about smaller, more powerful and less power-hungry chips for a long time. Now, development of such chips is likely to accelerate.
"Companies like Intel have focused on putting more transistors on a chip and making their products more powerful," said Anthony Townsend, research director at Institute for the Future. "It takes a while to turn a ship like that around." The rapid growth of all things mobile is accelerating that trend, Townsend said.
Besides being smaller and significantly more power efficient, tomorrow's mobile chip sets will also combine multiple radios, such as Wi-Fi, 3G and WiMax, on a single chip, according to the experts.
Why it's important: Smaller, more powerful chips mean smaller, more powerful mobile devices and applications. Combined with faster, ubiquitous wireless broadband, that means devices can be sewn into clothing, placed unobtrusively into ears or even implanted in your teeth.


Disruption 6: Wireless USB and ultrawidebandThese short-range, wireless cable replacement technologies are starting to be available. Admittedly, they lack the gee-whiz factor, but they eventually will make life much easier for mobile users.
Why it's important: At the very least, it will be nice to synchronize data between devices and desktops wirelessly. Short-range wireless cord replacements will also be useful for entertainment applications such as streaming video throughout the home. But the real benefit will be using these technologies with tiny mobile devices, according to Derek Kerton, principal of the Kerton Group, a telecommunications consulting firm.
"If we get miniscule phones, they could use wireless USB or UWB to connect to a full-sized keyboard," Kerton said. "Or we could have tiny devices that [use these technologies to] project usable keyboards on desks or images on walls."
What could hold it back: Not much. These technologies are already well established and should become widely used in the next couple of years.
Disruption 7: Nearly flawless speech recognition
Another mobile input application on the horizon is better speech recognition, which will be enabled by more powerful mobile chips.
"Speech recognition got bogged down because it was only 98% or 99% accurate," Burrus said. "Even at that accuracy, many of us found it was faster to type. A lot of the problem had to do with processing power -- speech recognition needs a lot of horsepower."
More powerful mobile processors will solve that problem, Burrus predicted. And speech playback will become more natural-sounding, he added. In other words, everything you do with your keyboard at your desk, you'll be able to do with speech while you're mobile.
Why it's important: If you have a teensy mobile device that is, say, tucked in your ear, better speech recognition and playback means you don't need a keyboard or display. You'll be able to perform complex functions such as Web searches or buying things using your voice.
What could hold it back: Users could be reticent about letting others in public places hear their business. They may prefer to combine better speech recognition with other methods of input.
Disruption 8: Foldable displays and e-paper
Vendors such as Philips and Fujitsu Computer Systems Corp. have been publicly showing foldable and e-paper displays for mobile devices. Both will enable tiny devices to display data clearly on easily stowed screens.
E-paper uses a mylar-like screen, said Paul Moore, senior director of mobile product marketing at Fujitsu.
Fujitsu Computer Systems is showing e-paper for mobile devices and other uses." src="http://www.blogger.com/common/images/site/features/2007/102007/e_paper.jpg" width=160 height=135>Fujitsu Computer Systems is showing e-paper for mobile devices and other uses."You can maintain the image with no power at all," he said. "So I take a small tube [of e-paper] out of my pocket, unfold it and there's the New York Times. I can use the same e-paper for tomorrow's paper."
E-paper will have a dramatic effect on laptops, Moore predicted. That's because, when it is improved enough that it can support constantly changing images and not just static ones, it can replace laptop LCDs. That will dramatically cut both laptop weight and power consumption, Moore said.
In addition, Japan's NTT DoCoMo is experimenting with e-paper to replace keys and icons on phones. With e-paper, those keys and icons can change as you change applications from, say, being in voice mode to being in media playback mode.
Why it's important: Foldable screens and e-paper mean we can easily have big displays with our miniscule mobile devices.
What could hold it back: The technology still must be perfected. Also unknown is how much such displays will cost.
Disruption 9: Centralized storage
Fast, ubiquitous wireless access will enable centralized storage on remote servers, which will have a series of important ripple effects, according to Burrus.
"You don't need a lot of bulk [on a device] if you offload storage and other functions to a [centralized] server," Burrus said.
Kerton agrees. "How much sense does it make to store a specific jazz album on your device and everybody else is storing it on their device, too?" Kerton asked. "We're doing massive edge storage and that doesn't make sense."
Why it's important: After faster, more powerful but smaller mobile chips, ubiquitous wireless connections and better input-output methods, centralized storage is the final step toward completely untethering mobile devices and those of us who use them.
What could hold it back: So far, Internet-based storage has not proved popular. It's hard to break old habits of local storage.
Better applications
So what do we do with these powerful, tiny, highly connected devices with satisfying input and output? The answer, of course, is new, innovative applications.
We can't hope to cover all the potentially disruptive applications of the future, but we can describe why a few will change your life. We'd love to hear your choices in the comments section of this story.
Disruption 10: Unified communications
Huge technology players such as Microsoft Corp. and Cisco Systems Inc. are pushing for the ability to tie together all forms of communications, including landlines and the various types of wireless. It's a compelling vision that is a stew comprised of many ingredients.
One futuristic ingredient in unified communications is sometimes called "superpresence," which is like a supercharged version of the instant messaging feature that lets you know if a buddy is online. In this case, superpresence could also provide information such as the best method at any given moment to communicate with a person or an estimate of when that they'll arrive at a destination. Users will create rules that say, for example, they can be interrupted by a spouse and boss, but not by others.
Another part of this stew includes technologies already mentioned, such as fixed-mobile convergence and femtocells, because they make it easier to locate and communicate with people Two more ingredients are the ability to transparently route communications to an individual via disparate networks and the ability to share applications in real time via those disparate networks.
Why it's important: One word describes why this is important: productivity. For instance, far-flung project teams will be much more efficient interacting with each other and exchanging ideas and other mission-critical information.
What could hold it back: At some point, employees may tire of being available 24/7, and unified communications will make it even harder than is currently the case to escape from work.

Disruption 11: Mobile commerce In Japan, cell phone users are increasingly using built-in near-field communications technology to swipe their phones near special point-of-sale terminals to buy things.

In Japan, cell phone users are increasingly using built-in near-field communications technology to swipe their phones near special point-of-sale terminals to buy things.

Proponents claim this technology has other functions. For instance, you'll swipe your phone near a concert poster to download more information about the performer and to buy tickets. Or swipe your phone near an in-store kiosk to get digital cents-off coupons.
Why it's important: Utter simplicity. No more fumbling around for your credit card or struggling to keep track of your purchases. And you can easily share the information with your desktop financial manager.
What could hold it back: Cellular operators, phone vendors and credit card companies are keen to get this off the ground. However, it would require merchants to buy new point-of-sale terminals, which could be a hard sell.
Disruption 12: Mobile security
Of course, security is needed for mobile commerce and many other next-generation applications. Burrus said not only will future phones be secure, but they'll be used in other contexts to ensure security.
"We'll have new levels of biometrics," he noted. "If your phone is in your ear, everybody's inner ear canal is different and the phone can tell. That's one form of biometrics. Similarly, everybody's voice is different. Or maybe the phone will discern blood vessel patterns in my ear." Then, there's fingerprint scanning, already common with laptops. Best of all, this security could be performed automatically, making secure transactions easier and faster.
Why it's important: Besides protecting your transactions and data, you'll be able to use your mobile devices to gain admittance to secure areas at work or maybe even at the airport.
What could hold it back: Advanced biometrics will be attractive to corporations, but it surely will add to the price of devices, which could lead to resistance, at least among consumers.


Disruption 13: Augmented reality
Imagine looking at something in the real world -- say a building -- through your mobile device, then putting a virtual overlay over it. Sounds like a game, but it potentially has some very real-world applications, according to Townsend.
"It will help anything that can benefit from simulation," he said. "An architect working at a construction site, or a firefighter finding a way out of a burning building or a UPS driver visualizing the next 10 steps of his delivery route." Another possibility: A surgeon performing a complicated procedure.
Why it's important: Augmented reality can help us understand the unknown in real time. That will lead to greater safety, more flexibility and better health care.
What could hold it back: This still remains the subject of a lot of research before it becomes practical and affordable.

This is my favorite wireless technology.

Sunday, February 14, 2010

importance of wireless technology

Newswise — Mirroring a trend among the general public, an increasing number of people with disabilities regularly use wireless technologies, including cell phones " and find them easier to use. But a number of people with disabilities cite a need for improved functionality of wireless devices, such as a feature to enable service dogs to call for help in an emergency, according to the initial results of a survey funded by the U.S. Department of Education's National Institute on Disability and Rehabilitation Research (NIDRR).

Wireless device ownership increased 13 percent " from 72 to 85 percent " among people with disabilities from the first generation of the survey of user needs " conducted from 2001 to 2006 " and the current survey, which began in April 2007. Also, more than three-fourths of respondents last year reported that their wireless devices are easy or very easy to use, compared to only half of those who responded to the earlier survey. Still, 73 percent said they likely would change wireless service providers, if necessary, to get additional features that enhance accessibility.

"The data these consumers share through our research helps our wireless industry partners meet customers' needs and also helps identify applications useful to people without disabilities," said survey project director Jim Mueller of the Wireless Rehabilitation Engineering Research Center (RERC), a collaboration between Atlanta-based Shepherd Center and the Georgia Institute of Technology. "We are not encouraging the wireless companies to make special products. We want products that will work for everyone."

The RERC, which received its second, multi-year grant from NIDRR in 2006, promotes equitable access to wireless technologies and encourages adoption of universal design "design that benefits users of all ages and abilities " in future generations of wireless devices and applications.

The 1,208 people who completed the RERC survey in 2007 are representative of a large portion of the estimated 40 million Americans with disabilities, researchers noted. They compared the demographics of survey respondents to the U.S. Census and noted that 77 percent of respondents are 25-61 years of age; 5 percent are younger; 18 percent are older.

Researchers are comparing and contrasting the initial results from the current survey to the RERC's previous user-needs survey of 1,200 people. Also, they are tracking trends among 165 people who have participated in both studies. In addition, researchers are comparing their results to findings reported by other wireless industry groups in 2007.

Here are some highlights from the analysis:

  • Comparing the earlier survey results to the current responses, researchers found that respondents who use their wireless devices every day increased from 40 to 65 percent. Those who consider their wireless devices "very important" increased from 60 to 77 percent.

  • Explaining why wireless devices are important to them, survey participants cited convenience and a sense of security " much like the general population. But they also noted that wireless devices often serve as assistive technologies. For example, one respondent noted, "The camera helps me remember things." Another participant reported that with the texting feature, "I can communicate with hearing people, like hearing people use cell phones."

  • Among respondents to the survey last year, 77 percent said they are satisfied, very satisfied or extremely satisfied with their current wireless provider.

  • About 68 percent of 2007 survey respondents said they are satisfied, very satisfied or extremely satisfied with their present wireless devices.

  • The most important wireless functions cited by survey participants are: voice communication, 78 percent; Enhanced 911, 45 percent; text messaging, 43 percent; e-mail, 41 percent; and Internet access, 35 percent.

  • The most important handset features to these users are: long battery life, 63 percent; durability and toughness, 61 percent; low cost, 57 percent; and simple operation, 56 percent.

  • Survey respondents suggested some additional features they would like to have in a wireless device: "feature to enable service dog to call for help in emergency" ; "ability to switch to voice carry-over during call (in case voice becomes unintelligible or environmental noise is too great)" ; and "[ability to] scan and speak medication labels."

  • Survey respondents also commented on ways to make wireless devices easier to use. Their comments related to: incompatibility with assistive technologies, especially hearing aids or cochlear implants, design of the handset, including their difficulties holding it, seeing the display, and manipulating the controls.
My favorite wireless device is cellphone.
Cell phones have become a necessity for many people throughout the world. The ability to keep in touch with family, business associates, and access to email are only a few of the reasons for the increasing importance of cell phones. Today's technically advanced cell phones are capable of not only receiving and placing phone calls, but storing data, taking pictures, and can even be used as walkie talkies, to name just a few of the available options.

When cell phones were first introduced to the public, they were bulky, expensive, and some even required a base unit that had to be transported along with the phone. Good reception was a major problem and in general, early cell phones could only be used in certain locations were the signal was particularly strong. As cell phone technology advanced, the difficult in using them became less of a problem. Today, cell phone reception has improved greatly due to the use of satellites and wireless services. As cell phones improved and became simple to use, the importance of cell phones increased accordingly.

Cell phones are the perfect way to stay connected with others and provide the user with a sense of security. In the event of emergency, having a cell phone can allow help to reach you quickly and could possibly save lives. However, the importance of cell phones goes way beyond personal safety. Modern cell phones are capable of internet access, sending and receiving photos and files, and some cell phones are equipped with GPS technology, allowing for use in most locations around the world and allowing the cell phone to be found or the user located in the event of loss or emergency.

Cell phone reception has become reliable and of high quality due to advances in wireless technology. Wireless service providers offer excellent packages and promotions for cell phone users. Finding a dependable service provider is no longer an issue for cell phone users. The expansion of the wireless service provider industry gives cell phone users a choice and the increased competition has caused a drop in prices of wireless cell phone service. The importance of cell phones goes way beyond the ability to make or receive phone calls. Cell phone users can instantly send data to the home or office, check for important email, use their cell phone as a PDA or calendar, and store photos which can be easily transferred to a PC or laptop computer.

Cell phone manufacturers have produced a wide range of cell phones, which sell for prices that range from very inexpensive to over one thousand dollars. The available options give users the choice of purchasing a basic cell phone to use simply for making calls, or choosing a complex, technologically advanced cell phone that can perform as many or even more tasks that a home computer. Over the past decade, the increasing importance of cell phones has made them almost a necessity for most people. Even remote and underdeveloped countries have some access to cell phone technology and wireless services.

The importance of cell phones has increased the competition in the wireless service provider industry, making cell phones very affordable and very easy to use. Cell phones have become almost a status symbol in addition to the convenience and security that comes from owning them.

Field Trip


I want this image because I like crocodiles. A crocodile is any species belonging to the family Crocodylidae (sometimes classified instead as the subfamily Crocodylinae). The term can also be used more loosely to include all members of the order Crocodilia: i.e. the true crocodiles, the alligators and caimans (family Alligatoridae) and the gharials (family Gavialidae), or even the Crocodylomorpha which includes prehistoric crocodile relatives and ancestors. Crocodiles are large aquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. Crocodiles tend to congregate in freshwater habitats like rivers, lakes, wetlands and sometimes in brackish water. They feed mostly on vertebrates like fish, reptiles, and mammals, sometimes on invertebrates like mollusks and crustaceans, depending on species. They are an ancient lineage, and are believed to have changed little since the time of the dinosaurs. They are believed to be 200 million years old whereas dinosaurs became extinct 65 million years ago; crocodiles survived great extinction events.
