(Phys.org) — A Los Angeles-based startup looking for Kickstarter pledges is seeing big bucks. Ouya wants to bring to market a $99 gamer’s home console with controller featuring free games. As of early Wednesday, Ouya was already topping $2.5 million with 28 days more to go. That people think their idea is welcome could be an understatement. What the company wants to do is to sell a free-to-play model that will make upstart history as “the people’s console.” To date, home gamers in a living-room environment pay for games upfront or a monthly fee to access libraries. © 2012 Phys.org The unit, under $100, carries features and a design concept that are additional drawing points in the project. Yves Behar, who designed the XO laptop for One Laptop Per Child, is behind the Ouya console design. The device is to come with eight gigabytes of flash storage, Nvidia’s Tegra3 quad-core processor, 1GB RAM, and Bluetooth connectivity (Bluetooth LE 4.0). There are standard controls (two analog sticks, d-pad, eight action buttons, a system button), and a touchpad. The games are connected up to the TV via HDMI connection, with support for up to 1080p HD.Games developed for the platform must have a trial portion that is playable for free. The system would have its own online store for finding titles. The business model for developers would be that, while only games with a free component would be featured, players could be charged in other ways. The developers could profit by offering a game upgrade, game items for purchase, or by asking users to subscribe. Developers would receive 70 percent of the revenue for anything they sell on the platform.The product is only in prototype stage, although the company team said they are far along in the user interface and industrial design process.

As for global reach, the Ouya team said, “Gaming is global, and we will get you OUYA. We still have a lot to figure out in regards to rights and countries, but it can be done.”Reactions to Ouya’s plans have been met with interest but also with a sobering wait-and-see. Said a blog in The Guardian: “While dollars pouring in are impressive, success will come in 2013, if the company uses that funding to deliver a device (and a store, and a developer ecosystem around it) that delivers on its considerable potential.” The Android-powered video game console would allow gamers to access free games that could be played out on big screens, up from just enjoying freebies on smartphones and tablets. Julie Uhrman, Ouya’s chief executive, has asked, ”With all our technological advancements, shouldn’t costs be going down? Gaming could be cheaper!” Her team is looking to make home gaming less expensive to make and less expensive to buy.

But it’s not difficult to see the concept being extended to people sitting in front of 3D video cameras (and Kinect devices), allowing for remote virtual touching. Reps for Different Dimensions say the company will be ready to begin taking orders for the new system as early as this March, though prices will be steep, ranging from $4,800 to $5,300. (Phys.org)—Researchers and engineers at a Japanese company called Different Dimensions have taken the concept of augmented reality to new heights by adding the touch of an avatar to the experience. That touch comes courtesy of a robot they’ve built that mimics commands sent from an animation generator—it’s covered with green material to allow for connecting augmented reality imagery with the real world robot. They call it a “virtual humanoid.” Explore further More information: wingover.jp/via Gizmag This document is subject to copyright.

Overlaying arrows on streets to provide driving directions, is one example. Another is where a person’s name appears in a bubble next to their face. This all is made possible by donning a helmet or goggles that allow the wearer to see through to the real world, but also allows information to be projected onto the glass in front of them that appears to be physically connected to the real world objects.In this new effort, the researchers thought it would be neat to allow for an animated human being to be projected onto a heads-up device, to create the illusion of conversing, and touching with a computer generated person, making them seem more alive. To make that happen, they created a three dimensional avatar, in software and then a green-material covered robot that exists in the real world. When a person wearing the goggles looks at the robot, they see the projected image of the avatar—in 3D, overlaid onto the robot. And as if that’s not enough, the robot can move its head, torso and arms, which means it can reach out and touch, and be touched by the person wearing the goggles as well, adding a dimension of intimacy that has never before been seen with an augmented reality device.

Rev. Lett. 114, 196602 – Published 13 May 2015. journals.aps.org/prl/abstract/ … ysRevLett.114.196602 . On Arxiv: arxiv.org/abs/1501.06691ABSTRACTWe report an experimental demonstration of room-temperature spin transport in n-type Ge epilayers grown on a Si(001) substrate. By utilizing spin pumping under ferromagnetic resonance, which inherently endows a spin battery function for semiconductors connected with a ferromagnet, a pure spin current is generated in the n−Ge at room temperature. The pure spin current is detected by using the inverse spin-Hall effect of either a Pt or Pd electrode on n−Ge. From a theoretical model that includes a geometrical contribution, the spin diffusion length in n−Ge at room temperature is estimated to be 660 nm. Moreover, the spin relaxation time decreases with increasing temperature, in agreement with a recently proposed theory of donor-driven spin relaxation in multivalley semiconductors.

In their paper published in the journal Physical Review Letters, the team describes their technique which could help lead to the development of spintronic devices. Spintronics is the science of searching for and using materials that can sustain a spin-polarized current. The hope is that devices based on spintronics could allow for faster and more efficient computers. Some have even suggested they could play a role in the development of true quantum computers. But for this to happen, materials must be found that can overcome spin–orbit interaction—where fluctuations in magnetic fields present in materials causes scattering, resulting in changes to spin, destroying the possibility of it carrying useful information. In this new effort, the research team describes their analysis of germanium as a possible useful material for spintronics.Prior research has suggested that germanium could carry spin current for a short distance if the material was in a very cold state—to find out if it might work also at room temperature, the researchers doped a layer of germanium with phosphorous (to serve as an electron donor) which grew on a silicon substrate. A spin current was injected (using microwaves) into the germanium via a ferromagnetic strip (which caused the spins to be aligned) placed on one side of the germanium layer. The current moved through the material towards a strip made of metal on the other side of the germanium layer, where it was subsequently detected by a device able to note spin polarization. The team reports that the current moved successfully through the strip, which was 660 nanometers thick, a distance comparable to other materials that are being tested and which is actually larger than the distance between size features in integrated circuits. That means a circuit could conceivably be made with information passing between two or more spintronic devices.The team also noted that cooling a germanium sample down to 130 K doubled the distance the spin current was able to travel before degradation grew to the point of significance.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Many beachgoers have encountered fiddler crabs and have likely noticed that the males have one oversized claw. This, the researchers contend, is to help the male attract the attention of a prospective mate, by waving it at her.To learn more about the mating behavior of fiddler crabs, the researchers studied them in their natural environment at East Point Reserve in Darwin, Australia over the period from September to November 2014. To make it easier to witness the mating action, they captured some females just prior to mating and attached them to wooden dowels, which allowed for placing them for easy observation. They also planted microphones in the sand near burrows that had been created by males—both for their own use and for a prospective mate. After studying the mating rituals of the males, each was captured and placed on an artificial track where they were urged to run with a wooden stick. This allowed the researchers to test their endurance.In watching the males and females interact, the researchers found that the females tended to prefer to mate with those males that had a larger claw and who also drummed the fastest. They believe the drumming is an indicator of physical strength and stamina (which was supported by track running tests), which suggests their fitness for caring for the female and offspring. The team also found that those males that drummed the most rapidly tended to have the largest burrows, which the females preferred, because after mating, they moved into their mates’ burrow to incubate their eggs. The researchers also found that drumming was an effective means for allowing the males to demonstrate their fitness, even while inside of their burrow—an arrangement that allowed the female to judge the male without the risk of being coerced into mating when taking a peek inside a burrow to see how large it was. More information: Multimodal communication in courting fiddler crabs reveals male performance capacities, Published 15 March 2017. rsos.royalsocietypublishing.or … /10.1098/rsos.161093AbstractCourting males often perform different behavioural displays that demonstrate aspects of their quality. Male fiddler crabs, Uca sp., are well known for their repetitive claw-waving display during courtship. However, in some species, males produce an additional signal by rapidly stridulating their claw, creating a ‘drumming’ vibrational signal through the substrate as a female approaches, and even continue to drum once inside their burrow. Here, we show that the switch from waving to drumming might provide additional information to the female about the quality of a male, and the properties of his burrow (multiple message hypothesis). Across males there was, however, a strong positive relationship between aspects of their waving and drumming displays, suggesting that drumming adheres to some predictions of the redundant signal hypothesis for multimodal signalling. In field experiments, we show that recent courtship is associated with a significant reduction in male sprint speed, which is commensurate with an oxygen debt. Even so, males that wave and drum more vigorously than their counterparts have a higher sprint speed. Drumming appears to be an energetically costly multimodal display of quality that females should attend to when making their mate choice decisions.

Walking down three decades of Polish reactionary music set in the era of communism, a collaboration between the Polish Institute and India Habitat Centre brings you an documentary Beats of Freedom (Zew Wolnosci) in the Capital. Directed by Leszek Gnoinski and Wojciech Slota, it is slated for a screening in Gulmohar Hall on 21 July. This 72 minutes long documentary is a story about Polish rock music and independence.The Iron Curtain was not as impermeable as it may have seemed; western music was available in Poland; and sometimes even big stars visited the country, the outstanding example being Also Read – ‘Playing Jojo was emotionally exhausting’The Rolling Stones’ visit in April 1967. Those two legendary concerts had a huge impact on Polish rock music. Both took place in Warsaw’s Congress Hall, located in The Palace of Culture and Science – a gift from the Soviet Union to the people of Poland. Paradoxically, this hated symbol of communist power became an important testimony to the history of Polish rock’n’roll.The film’s narration makes it an interesting and entertaining documentary. Chris Salewicz meets Tomek Lipinski (lead singer of the bands Tilt and Brygada Kryzys), Piotr Naglowski (manager and journalist), and Mirek Makowski (photographer and historian). Their stories are not only about the meaning of their music, but also about Polish life under the communist regime. Sometimes those stories are heart breaking, and sometimes they tell of undying hope.

More than one out of three Indians 36 per cent – share personal data or sensitive information using public Wi-Fi while travelling which can lead to data stealing, a study by Intel Security revealed on Tuesday. The ‘Digital Detox: Unplugging on Vacation’ study was conducted across 14 countries (including India) with 14,000 people to understand consumer behaviour when travelling. India leads the pack when it comes to sharing information online. “Through this survey, we wanted to raise awareness about the need to adopt safe digital habits and share security measures to prevent personal information from being compromised while travelling,” said Venkat Krishnapur, Head, R&D Operations, Intel Security’s India Development Centre, in a statement. Also Read – Add new books to your shelfNearly 37 per cent of Indians could not last a day on vacation without checking social media. This was second only to Japan (45 per cent) when compared globally. Majority of Indians (54 per cent) were not willing to leave their smart phone at home while on vacation. “Travelers can be targets for cybercriminals who count on human and device vulnerabilities to provide them with a point of access to consumers’ data and devices. They can gain access to sensitive information via unsecured smartphones, laptops and even wearables, while also collecting data from social channels,” the findings showed. Connecting to unprotected Wi-Fi and Bluetooth devices can expose personal information to a cybercriminal. One should be especially careful when exchanging payment information. “With this in mind, make sure to update your Bluetooth and Wi-Fi history by removing previously ‘remembered’ wireless networks, like ‘cafewifi,’” the study noted.Whether it’s your location or selfie, criminals are more able to monitor your whereabouts via social activity and take advantage of you when you have the weakest protection. The pervasive use of technology in our day-to-day lives and popularity of bring-your-own-device (BYOD) ties our personal and work lives more closely than ever before – especially on vacation. “This can puts travellers at risk as they share their personal/confidential information online,” the study noted.

If you are a bullying boss, your employees are more likely to be less committed to their work, take longer breaks or come in late without notice, finds a study. The study led by researchers from the Portland State University in Oregon, US, showed that a bullying boss can decrease “organisational citizenship behaviour”, or the voluntary extras one does that are not part of the job responsibilities. On the other hand, the study also reveled that he/she increases “counterproductive work behaviour”, such as sabotage at work, coming into work late, taking longer-than-allowed breaks, doing tasks incorrectly or withholding effort, all of which can affect the team and co-workers. Also Read – Add new books to your shelf”The findings highlight the consequences of abusive supervision, which is becoming increasingly common in workplaces,” said Liu-Qin Yang, Associate Professor at the University. The study, published in the Journal of Management, attributes negative work behaviour to either perceptions of injustice or work stress. In response to perceptions of injustice, the employees are more likely to purposely withhold from the unpaid extras that help the organisation, like helping co-workers with problems or attending meetings that are not mandatory. Also Read – Over 2 hours screen time daily will make your kids impulsiveHaving an abusive boss can also lead to work stress, which reduces an employee’s ability to control negative behaviour or contribute to the organisation in a positive way. “Stress is sometimes uncontrollable. You don’t sleep well, so you come in late or take a longer break, lash out at your co-workers or disobey instructions,” Yang further added. “But justice is more rational. Something isn’t fair, so you’re purposely not going to help other people or when the boss asks if anyone can come in on a Saturday to work, you don’t volunteer.” The researchers of the study have highly recommended that organisations should take measures to reduce or curb abusive supervision. Regular training programmes to help supervisors learn and adopt more effective interpersonal and management skills, implementing fair policies as well as conducting stress management training can help employees, they suggested.
Johnny Appleseed is an American folk hero, known as an intrepid outdoorsman who spent his days planting apple trees along the western frontier. The myths and legends surrounding his life have been exacerbated by popular depictions of him as a jolly farmer, surrounded by rosy apples, singing birds and bucolic countryside.Johnny Appleseed, Harper’s New Monthly Magazine, 1871According to Professor William Kerrigan, Johnny Appleseed has come to be regarded as ‘St. Francis of the apples’, wandering along the American frontier, dressed in rags, and a coffee sack, distributing apple seeds and planting trees.AdChoices广告inRead invented by TeadsAs a follower of the teachings of the Swedish theologian Emanuel Swedenborg, he believed that suffering in this life would lead to happiness in the hereafter, and therefore he is said to have traveled barefoot, as a humble pilgrim, befriending Native American tribes, protecting nature, and cultivating the land.Johnny AppleseedHowever, this saccharine picture of a harmless proto-hippy belies the true story of Johnny Chapman, an enterprising businessman who fuelled the burgeoning cider industry and paved the way for expansion and settlement into the Midwest.Kerrigan reports that Chapman did indeed plant apples along the western frontier, but they were primarily used for drinking, not eating. In addition, the construction of this image of benign eccentricity has obscured the role he played in facilitating the displacement and destruction of Native American communities in the Northwest Territory.A variety called the “Johnny Appleseed” is similar to these Albemarle Pippins, good for baking and apple sauce. Photo Leslie Seaton CC BY 2.0Chapman was born in Leominster, Massachusetts, in 1774. His early years are shrouded in mystery, but we do know that he turned up in Pennsylvania at the turn of the 19th century, at a time when expansion westwards was accelerating significantly. The colonization of the Northwest Territory was in full swing, and many large private companies and investors were buying up land for settlement.According to The Smithsonian Magazine, in 1792 the Ohio Company of Associates developed a policy to encourage migration to these areas. Potential settlers would be granted 100 acres of land if they permanently settled there, and permanent settlement was defined by the planting of apple and peach trees. This was considered to be evidence of a long-term investment, as apple trees planted from seed tended to take around a decade to bear fruit.Published November 1871 in Harper’s New Monthly MagazineChapman realized that there was a lucrative opportunity in this new context. If he could travel the frontier planting apple trees, he could successfully hand them over to incoming frontiersmen at a considerable profit. He would undertake the difficult work of raising the orchards, and sell them on later.His religious beliefs prohibited him from using grafting techniques to cultivate apples, so he decided to plant his orchards in carefully constructed nurseries, from seed. However, planting apples from seed is an unreliable, unpredictable business, and the yield rarely produces apples suitable for eating. Rather, the apples that Chapman planted would have been unbearably sour, even if taken from the seed of a sweet eating apple.Ripe red apple close-up with sun rays and apple orchard in the background.As a result, Chapman’s apple trees were used to produce cider. In this period, water was generally considered unsuitable for drinking, as it could not be sterilized, and so the majority of people quenched their thirst with weak ale or other alcoholic beverages.Apple cider became the beverage of choice along the American frontier, and was drunk by men, women and children alike. Author Howard Means even describes frontier life in this period as being lived “through an alcoholic haze”, according to The Smithsonian Magazine, due to the vast quantities of strong cider that were consumed.Basket with red apples on the grass in the gardenChapman died in 1845, an extremely rich man, leaving over 1200 acres of nurseries to his sister. To the end, he deprived himself of material comforts, and continued to proselytize for the New Church of the Swedenborgians throughout his life.Johnny Appleseed grave Kevin M. Brooks CC BY SA 3.0However, during prohibition, the majority of the orchards that he had planted were ripped up by the authorities, due to their role in fuelling the production of cider.Nevertheless, his development of new American apple strains has left a legacy to this day, producing popular, hardy types of apples that continue to enjoy popularity across the United States.US stamp honoring Johnny AppleseedJohnny Appleseed has emerged as an emblematic image of mythologized frontier life. His kindness, strong religious faith and enterprising spirit appear to embody the American dream, and it is no wonder that he has become known as a folk hero in the national origin story.Read another story from us: Campaign to Save the Grave of the Man who Invented Special Effects for FilmHowever, as Kerrigan notes, the real story of Johnny Chapman is far more complex and ambiguous. The myth serves to obscure the brutality and hardship of frontier life, and the price paid by Native communities for American expansion into the Midwest.
