Google patent sends ring signals to Project Glass

first_img Sony patent seeks to correct autostereoscopic blur Explore further The popular translation of this patent can be worded as something like Google has revealed how its Project Glass video glasses will actually work, and the answer is with hand gestures via rings, fake nails, or some sort of hand tattoo. A certain gesture pattern could launch an application or open a document.According to the patent, the reflective infrared identifier that is placed on a user’s hand is able to track and identify the user’s gestures. The head-mounted display and IR camera device can function together. The infrared camera is integrated into the user’s head display to track the image. The camera would pick up radiation reflected from the marker, as a point of reference for user control. IR reflective material could be an IR reflective paint, and an IR absorptive material could be an IR absorptive paint. The patent provides insight into yet another possibility in wearable computer interfaces. Some users may feel self-conscious about talking aloud in public, with voice-based control systems, whereas control gestures in the form of head-nods may also look odd to passers-by. As for the hand-gesture idea, one blogger suggested it may be no-less conspicuous as if one was conducting music, without the music. Another reactive line of discussion this week is whether or not the patent means anything more than a patent. Most suggestions point to the patent as part of a grand scheme of project development for Google’s glasses.Google announced Project Glass last month, where a special research team is testing prototypes outside the office. Closer details for this “Augmented Reality system,” or a smartphone-free smartphone in the form of video glasses, are not to be had, as the project is in its early stage. The patent revealed earlier this week, though, suggests that Google’s “wearable marker for passive interaction” is on the roadmap as one among other input solutions for Project Glass. More information: Patent online: patft.uspto.gov/netacgi/nph-Pa … S=8179604&RS=8179604 (Phys.org) — Google’s September 2011 patent that was filed for a wearable display device was granted this week, which suggests that its envisioned heads-up display device can be controlled by infrared markers in the form of devices worn on the hands, such as fake fingernails or rings. The patent says, “A wearable marker may take the form of a ring, a bracelet, an artificial fingernail configured to be affixed to a fingernail, a decal configured to be affixed to a fingernail, or a glove, among other possible wearable items.” Citation: Google patent sends ring signals to Project Glass (2012, May 19) retrieved 18 August 2019 from https://phys.org/news/2012-05-google-patent-glass.html © 2012 Phys.Org Image from USPTO.

DOI: 10.1103/PhysRevLett.120.054503 Physicists study bubbles and droplets because of the unique processes involved, and because doing so has led to the development of many useful applications such as inkjet printers. In this new effort, the researchers applied known properties of glycerol-water solutions in a unique way to generate liquid-suspended air bubbles containing a liquid drop inside of them.To create such bubbles, the researchers forced small amounts of alternating liquid and air through a tube into a tank filled with a liquid solution, causing the generation of a so-called “Taylor flow,” alternating “slugs” of liquid and air bubbles. When an air bubble entered the tank, it was forced off the nozzle by the slug behind it—and when the conditions were just right, the team reports, that push by the slug forced a droplet into the air bubble, which then persisted in the solution for a length of time—the drop was released when the bubble encountered a solid surface, i.e., ran into the side of the tank. The team refers to their creation as a “drop encapsulated in a bubble.”The group further reports that for encapsulation to occur, the ratio of surface tension on the bubble to the degree of viscosity must be at a certain point as must the height to width ratio of the slug as it begins to make its way into the bubble. They note also that the drop inside the bubble showed an ability to withstand sheer flow. They suggest the technique could lead to the development of new ways to deliver medications or a means for processing materials in a manufacturing environment. One example, they point out, would be a novel way to create capsules of different sizes. They also note that it could be used as a means of fluid transport.center_img Journal information: Physical Review Letters A team of researchers at Zhejiang University in China has developed a technique to create liquid droplets inside of air bubbles.

Heres why you spend spare time on

first_imgCan’t help skimming through your Facebook timeline even as you take a break from work? You may just be wired to do so as the brain prepares us to be socially connected to other people even when we get some rest, says a new research.“The brain has a major system that seems predisposed to get us ready to be social in our spare moments,” said the study’s senior author Matthew Lieberman, professor at University of California, Los Angeles. During quiet moments, the brain is preparing to focus on the minds of other people — or to “see the world through a social lens,” Lieberman said. Also Read – ‘Playing Jojo was emotionally exhausting’Tracking brain activity of study participants using functional magnetic resonance imaging, or MRI, the researchers found that a brain part called dorsomedial prefrontal cortex might turn on during dreams and rest in order to process our recent social experiences and update our understanding of the social world.“It is part of a network in the brain that turns on when we dream and during periods of rest, in addition to when we explicitly think about other people,” Lieberman said. Also Read – Leslie doing new comedy special with Netflix“When I want to take a break from work, the brain network that comes on is the same network, we use when we are looking through our Facebook timeline and seeing what our friends are up to,” Lieberman said.So although Facebook might not have been designed with the dorsomedial prefrontal cortex in mind, the social network is very much in sync with how our brains are wired.“That is what our brain wants to do, especially when we take a break from work that requires other brain networks,” Lieberman said.The study was published in the Journal of Cognitive Neuroscience.last_img read more

Arts Acre a complete haven for connoisseurs

first_imgAn idyllic setting, a museum of Modern Art from Bengal, galleries showing curated short-term exhibitions. Add to that a museum shop and a well-equipped conservation laboratory, an auditorium and a cafeteria and you know why Arts Acre has found its place as the latest tourist hub of Kolkata.  With winter giving way to spring, Arts Acre is buzzing with children from over 250 city schools, who are camping out in the sun and spending hours soaking in the art on display in the museums of Bengal Art and Indian Art, taking in the workshops where artists are creating live art every day. “We have tried to create an atmostphere that would remind one easily of the art appreciation courses taught in European schools. The children — when visiting the museums — are inbibing a chronological history of modern art from Bengal and India”, said veteran artist Shuvaprasanna.   Also Read – ‘Playing Jojo was emotionally exhausting’The brainchild of Shuvaprasanna, Arts Acre also has space for workshops and studios, an open-air theatre, guest apartments and conference facilities. The facility was formally inaugurated on March 6, 2014 by Mamata Banerjee, the Chief Minister of West Bengal and luminaries representing major arts from across India – Mahashweta Devi, Karan Singh Balmuralikrishna, Pandit Birju Maharaj,  Anjolie Ela Menon —came together  for the launch — which was punctuated with a lyrical presentation of music and poetry. Subsequently, the Sarla- Basant Birla Auditorium at Arts Acre was inaugurated by MK Narayanan, the ex-Governor of West Bengal, in the presence of Sarala and Basant Birla. Designed by visionary architect and urban designer Partha Ranjan Das, Arts Acre is a self-complete mini-city for artists and art lovers — one of its kind in this part of India.  Also Read – Leslie doing new comedy special with NetflixThe 165,000 sqft Arts Acre campus is a seamlessly flowing gallery space with the corridors, the double-height atrium, lobbies, foyers and flexible multi-utility halls representing a continuous exhibition of paintings and sculptures and walls serving as a canvas for expressing creativity.  The new Arts Acre campus is located at Rajarhat Newtown, east Kolkata’s rapidly growing satellite city. Minutes ride from the Axis Mall and Hidco Bhavan, just ahead of The Tata Medical Centre, Arts Acre was conceived as an institution for nurturing young artists in the field of visual arts. On  March 3, 1984, the sitar maestro Pandit Ravi Shankar laid the foundation stone of the original ArtsAcre.    This crystallised into an institution of national and international importance. Gradually, the campus became a shelter for budding artists and a meeting point for men of letters.The modestly-built original campus was inaugurated on January 11, 1987 by Nobel laureate Günter Grass with an exposition of his drawings. Chintamani Kar, Mrinal Sen, Bhabesh Sanyal, Subhas Mukhopadhyay, Ashok Mitra, Santosh Kumar Ghosh, Arun Mitra, Mulk Raj Anand, Khushwant Singh, Sibnarayan Ray, NS Bendre, Annada Shankar Ray, Satish Gujral and Manjit Bawa among other eminent personalities were associated with ARTS ACRE. They visited the campus often to encourage the artists. Guest artists from around the world came and worked at the old Arts Acre. An exchange programme with international artists led to exhibitions by Arts Acre artists in London and Washington eventually.  So what is the new Arts Acre all about? The Museum of Bengal Modern Art is one of its kind in India. It showcases the evolution of Bengal art from colonial times including traditional art forms, different group movements, the works of pioneering stalwarts to the new generation of artists. The 40,000 sqft space includes English lithography, Chorbagan prints, Kalighat pats, the Tagores, Ramkinkar Baij, Nandalal Bose, Jamini Roy, Paritosh Sen, Ganesh Pyne, Bikash Bhattacharjee and new generation artists like Samir Roy, Chandra Bhattacharya, Bhabotosh Suttar.  The Museum has galleries, named after donors, such as the Surrendra Paul Gallery, Emami gallery, Purna Chandra Paul gallery, Saroj-Jyoti Poddar gallery and Prabhat Chandra Sen gallery. The Museum presently has in its possession about 1000 artworks. The collection is envisaged as one of the most important bodies of Modern Bengal Art. Debdutta Gupta and Nilanjan Banerjee are involved in curating the museum. “We are also building a museum of modern Indian art. But it is not yet complete”, confirms Shuvaprasanna.   Trustees of Art Acre and noted art collectors  have contributed liberally to the museums’ collection, he added. Conservation Laboratory: The 1,600 sqft Conservation Laboratory is one of its kind. It offers infrastructure and expertise for restoration and conservation of paintings, sculptures and manuscripts. It has a sophisticated and well-equipped lab, that is managed by experienced conservator Partha Pratim Saha and team. The lab also has storage facility, natural light area for restoration. The Conservation Centre organises workshops, camps, seminars and trainings conducted by in-house and well-known conservators from around the globe.  The Auditorium: The Sarala-Basant Birla Auditorium, Samlap, is a state-of-the-art facility with the seating capacity of 400 people equipped with appropriate green rooms, lighting, projection and sound systems with skillfully engineered acoustics that ensure a high quality viewing experience. It is a multi-functional theatre where plays and other performing arts including film screenings can be hosted.  The Workshops: Studio- Workshops of 700 sq ft to 1500 sq ft with 15 feet high ceilings are used by artists, both professionals and aspirants. The fully equipped workshops include Graphic (Printmaking), Ceramic, Painting, Serigraphy, Sculpture, Photography, Film making and Lithography. Each workshop can comfortably accommodate at least 20 practitioners at a time. They are well equipped with modern infrastructure. The workshops are headed by noted artist Samir Ray. Swapan Jana, noted ceramicist, is in-charge of the Ceramic and Pottery Workshop. Acclaimed graphic artist Atin Basak is in charge of the Print and Graphics Department.   Film workshops will be conducted under the guidance of celebrated film maker Gautam Ghose.   The Studios: There are 15 Studios of about 300 sqft each. They are well illuminated and airy. Available for artists working independently, they have round-the-clock water, electricity and other basic infrastructure. Besides a host of special privileges, the 2000 sq. ft. Friends of Arts Acre Lounge offers exclusive access to members to relax, unwind and socialise away from the city’s din and bustle.last_img read more

Your baby might be watching what you eat

first_imgAt the dinner table, babies pay close attention to what food is being eaten around them – and especially who is eating it, suggests an interesting study. The findings showed that one-year-old infants expect people to like the same food, unless those people belong to different social or cultural groups, such as those that speak a different language. “Kids are sensitive to cultural groups early in life. When babies see someone eat, they are not just learning about food – they are also learning about who eats what with whom,” said Katherine Kinzler, Associate Professor at the Cornell University in New York, US. Also Read – Add new books to your shelfThe study supported the well-known fact in developmental psychology that babies will look longer at novel actions or things that deviate from their general expectations of the world. “An ability to think about people as being ‘same versus different’ and perhaps even ‘us versus them’ starts very early in life,” Kinzler added.Furthermore, babies were also found to have a slightly different take when it comes to food that might harm them. When the babies saw a person act disgusted from eating a food, they expected that a second person would also be disgusted by that food – even if the second person was from a different social group. Also Read – Over 2 hours screen time daily will make your kids impulsiveThis suggests “infants are particularly vigilant to social information that might signal danger”, the study said.In addition, the team also discovered an insight into what babies identify as meaningful cultural differences.While monolingual babies expected people who speak different languages to like different food, bilingual babies expected that people who speak different languages would eat the same food. They might have had experience with this in their own home, where people speaking different languages are gathered around the table, the researchers explained. Moreover, parents might need to consider that their children are watching as they eat together.  “If you feed your child the perfect diet, yet your child sees you and your friends and family eating junk food, she is presumably learning about foods from her social experiences, too,” Kinzler said in the paper published in the Proceedings of the National Academy of Sciences.  The team set up a series of studies in which they showed more than 200 one-year-olds a series of videos of people expressing like or dislike of foods.When the babies saw two people in the video speak the same language or act as if they were friends, the infants expected them to like the same foods. When they saw two people who spoke different languages or acted as if they were unfriendly, the babies expected them to like different foods, the researchers concluded.last_img read more
