Citation: Qeexo screentouch experience puts knuckles and nails to work (w/ video) (2012, November 17) retrieved 18 August 2019 from https://phys.org/news/2012-11-qeexo-screentouch-knuckles-video.html © 2012 Phys.org Explore further (Phys.org)—Touchscreen computing as an “experience” has only just begun. Working on ideas they seeded at Carnegie Mellon, computer-human interaction researchers have started a San Jose, California, company Qeexo, that features technology called FingerSense. With FingerSense, the computer user can perform tasks with more than just the finger’s tips, expanding the use of the finger over to using knuckles and nails. Each part of the finger can order up different tasks, such as managing e-mail content, managing objects in computer games and rubbing-in features when sketching a face. They have managed to expand the concept of fingerpad as the sole interface that can be used on the touchscreen. This document is subject to copyright.

TapSense touchscreen technology distinguishes taps by parts of finger (w/ video) More information: chrisharrison.net/projects/tapsense/tapsense.pdfwww.qeexo.com/ They are showing the world expanded finger options. Tomorrow’s mobile user may think nothing, for example, of knocking twice with a knuckle to bring up a new page.The company website is thin on technical details; little is said how it is done under the hood, but their video offers an impressive appreciation of what is done. When playing games, for example, the user knocks coconuts with knuckles, squashes berries with fingerpads, and slices bananas with nails. But how does Qeexo’s technology enable the computer to differentiate between fingertip, nail, or knuckle on a touch screen? Their FingerSense technology involves an acoustic sensor that is small enough to fit inside a smartphone and can capture mechanical vibrations made by various touches. This can pick up on different “sounds.”Chris Harrison, Julia Schwarz, and Scott Hudson, authors at Carnegie Mellon of a paper on finger interaction on Touch Surfaces, noted back in 2011 how “humans use different parts of their fingers in different ways – to scratch an itch, type on a keyboard, tap a co-worker on the shoulder, or knock on a door.” They thought about this and how, with careful design, these norms could be leveraged “such that existing finger behaviors could be ported to and made relevant in digital domains.”At a time when direct-touch interfaces are around in everyday life, from mall store kiosks, to tablets and smartphones, it is not difficult to understand that Qeexo is upbeat about its future. Qeexo was spun off from Carnegie Mellon University this year and there is both an office in San Jose and also a R&D team in Pittsburgh. According to reports, they are talking to phone manufacturers, and they hope to see FingerSense in smartphones within a year.
Information and gravity may seem like completely different things, but one thing they have in common is that they can both be described in the framework of geometry. Building on this connection, a new paper suggests that the rules for optimal quantum computation are set by gravity. Physicists Paweł Caputa at Kyoto University and Javier Magan at the Instituto Balseiro, Centro Atómico de Bariloche in Argentina have published their paper on the link between quantum computing and gravity in a recent issue of Physical Review Letters.In the field of computational complexity, one of the main ideas is minimizing the cost (in terms of computational resources) to solve a problem. In 2006, Michael Nielsen demonstrated that, when viewed in the context of differential geometry, computational costs can be estimated by distances. This means that minimizing computational costs is equivalent to finding minimal “geodesics,” which are the shortest possible distances between two points on a curved surface.As this geometric perspective is very similar to the concepts used to describe gravity, Nielsen’s results have led researchers to investigate possible connections between computational complexity and gravity. But the work is challenging, and researchers are still trying to figure out basic questions such as how to define “complexity” in holographic models related to quantum gravity, in particular, conformal field theory. Currently there are many different proposals for laying the foundations in this area.The main purpose of the new paper is to bring these different ideas together by proposing a universal description of complexity that depends only on a single quantity (central charge). This leads to the discovery of connections between complexity and concepts in (quantum) gravity which, in turn, leads to interesting implications such as the possibility that gravity governs the rules for optimal quantum computation. “Recently, quantum computation theorists (including Nielsen) put forward the idea that the complexity of quantum circuits can be estimated by the length of the shortest geodesic in the ‘complexity geometry of unitary transformations,'” Caputa told Phys.org. “We showed that, in two-dimensional conformal field theories with quantum gates given by the energy-momentum tensor, the ‘length’ of such geodesics is computed by (the action of) two-dimensional gravity. “Finding the minimal length on the complexity geometry, in our setup, is equivalent to solving the equations of gravity. This is what we meant by gravity setting rules for optimal computations in 2-D conformal field theories.”This perspective suggests that gravity could be useful in estimating computational complexity and identifying the most efficient computational methods for solving problems.”The notion of complexity of a certain task tells us how difficult it is to perform it using our available tools,” Magan said. “In the quantum theory of computation, this notion is generalized to the complexity of quantum circuits built out from quantum gates. Estimating it is in general a difficult problem. “We showed that there are families of quantum systems where the complexity of certain universal tasks is well estimated using classical gravity (general relativity). Over the years, using holography and Anti-de Sitter/conformal field theories, we have been learning that gravity is intimately related to quantum information. The lesson from our findings is that gravity may also teach us how to perform quantum computation in physical systems in the most efficient way.” Citation: Optimal quantum computation linked to gravity (2019, June 28) retrieved 18 August 2019 from https://phys.org/news/2019-06-optimal-quantum-linked-gravity.html © 2019 Science X Network This document is subject to copyright.

Kolkata: The Bengali New Year’s celebrations for the inmates of Alipore Women Correctional Home came a day later. However, they had no reasons to regret as their second day of the Bengali New Year (Doosra Baisakh) began in a grand manner with Carlyta Mohini Maria entertaining them for more than an hour churning out her popular numbers one after the other.”We decided to give our inmates an experience that they will cherish through out their lives. They are within the four walls of the prison but on this auspicious occasion when the entire state celebrated on their own way, the 300 odd inmates were also entertained to their hilt as they joined in chorus and clapped for Also Read – Heavy rain hits traffic, flightsMaria’s solo cultural programme,” said Arun Kumar Gupta, Director General of state Correctional Services. Maria, an Indo-Brazilian singer and songwriter, is known for her popular number ‘Senorita’ from the film ‘Zindagi Na Milegi Dobara’ in 2011. She had preformed for the inmates in a number of prisons across the country that includes the Tihar jail in Delhi, Arthur Road jail and Byculla Jail in Mumbai, Yerawada Central Jail in Pune, and Jodhpur Central Jail.

The excitement among them was palpable with their sparkling eyes and smiling faces as they joined in chorus,” Maria said.”The most interesting part of the programme was Maria’s ability to make the inmates involved in her performances. Apart from her popular foot tapping Bollywood numbers, she sang Baul songs and made the inmates sing with her,” Das said.According to sources in the Correctional Administration department, Maria who came to the city a few days back was roped in by Social Entrepreneur Chaitali Das of Rakshak Foundation who has been providing skill development training to the inmates of the Home on manufacturing jute products for the last few years. It may be mentioned that Maria who is a Brazilian with Portuguese as her mother tongue is widely popular in Bollywood with popular songs like ‘Delhi ki Sardi,’ ‘Le Le Maza Le’, etc to her credit.The Presidency Central Correctional Home situated only a few kilometers away from the Women home had Dev and Rukmini Mitra amongst them on Sunday evening (Poila Baisakh) as they watched a compilation of the best scenes from the film ‘Kabir’.
Kolkata: Holding that global trade is passing through “challenging times”, Union Commerce and Industry Minister Suresh Prabhu on Saturday said the existence of World Trade Organisation (WTO) was under threat.According to him, WTO is “a must” and in its absence, there will be chaos in the global trade.”Today, it is the most challenging time for global trade… we never had such a challenging time. For the first time, the existence of WTO is under threat. People are questioning the accepted trading norms,” he said at an event organised by Federation of Indian Export Organisations here.Citing an example of “letter of credit”, a prerequisite for exports, Prabhu said fundamentals of global trade are “under scrutiny”.”If you don’t have WTO, not only India, every country will have a problem. We strongly feel WTO is a must because it guarantees certain rules and regulations to run global trade. There will be chaos if you don’t have WTO.”Prabhu said the country was trying to make the global organisation strong.He also said as part of its long-term aviation policy, the Central government is working on an integrated plan to transform India into an aircraft and allied components manufacturing hub.”The aim is not only to create “millions of jobs” and boost the economy but also to position India as a global leader,” the minister said while delivering the 2nd CII Suresh Neotia Memorial Lecture.He said the government is working on a policy for aircraft components manufacturing. “We are already in discussion with the secretaries of key departments as well as international aircraft manufacturers, including Boeing and Airbus.”We are creating a comprehensive Policy for 2035 in aviation — a sector in which India has been clocking 20 percent growth in the past few years. It is a sector where India can play a leadership role in the world,” he told the industry leaders.
DiamondHarbour(WB): A local BJP leader in West Bengal’s South 24 Parganas district was hacked to death by unidentified miscreants in Mandir Bazar area of the district, police said today. Shaktipada Sardar (45), the secretary of BJP Mandal committee of Mandira Bazar-Dhanurhat area was returning home last night when miscreants attacked him with sharp weapon and left him bleeding on the road, they said. The local people spotted Sardar lying on the road and rushed him to Diamond Harbour Hospital. As his condition deteriorated, the hospital referred him to a hospital in Kolkata. However, Sardar died while being taken to a hospital in Kolkata, they said. Police said they have started an investigation into the matter. The BJP alleged that Sardar was killed by Trinamool Congress goons. The Trinamool Congress has denied the BJP allegations.
Kolkata: Another complaint of negligence was filed against a private hospital in the city.

Sources informed that the attendant was sleeping and the nurse was busy with some thing else. A complaint was filed at Behala police station about the negligence from the hospital end. On Thursday morning, around 8:40 am, Sarbani’s family members were informed that she passed away. The hospital authority termed the incident as an accident and denied the allegation of negligence. “Hospital authority told us that it was an accident. My mother was admitted to get blood. I want stringent action to be taken against the hospital authority,” said Sarbani’s daughter Tiyasa. Sources informed that the family of Sarbani is thinking of filing a complaint with the health commission against the private hospital.
The story has gone down in history as an epitome of true love. But did it ever cross your mind how the serious topic could be given an amusing twist and showcased in a jocular manner?Pankaj Kaintura took to himself the daring task of blending the true tale of love with the right amount of humour. The result was a play Dastaan-e-Laila which was performed at Akshara Theatre in the national Capital on Sunday. While Majnu (here Jugnu) is seen as a mad, unconditional lover, Laila on the flip side is materialistic by nature. She wishes to marry a man who can provide her money as it is the be all and end all for Laila. Also Read – ‘Playing Jojo was emotionally exhausting’The conversation between Jugnu and Manchala, Laila’s would-be husband, was at its best where the audience just couldn’t hold back their laughter for a nanosecond. Laila played by Rukhsar Khan was prompt with her dialogue delivery, while Jugnu played the perfect ‘Majnu’. Manchala was perfect at adding humour. Thus, nowhere does the play lose its intent to tickle the funny bone of the audience.From the glitter in Laila’s attire to the rags worn by Jugnu and also the nawabi black suit of Chotte Nawab with his white beard, the costumes well-complimented the play. Also Read – Leslie doing new comedy special with NetflixThe lights had also been taken good care of by decreasing the brightness when Laila performs her mujra and simultaneously increased when the dialogues were delivered.The play added strokes of humour with Sher-o-Shayari delivered from time to time. This story of Laila-Majnu was depicted from the modern day perspective of love, that left the audience pleasantly surprised. Aspirations of modern day Laila, as the play intended to show, came out perfectly. Each character played their part well. The hour-long play kept the audience glued to their seats throughout. The climax, when all characters come to the fore, where Laila is in a ‘trilemma’ and has to choose from Chotte Nawab, Jugnu and Manchala is worth watching for to see how she chooses money over everything else. The play ends on a funny note with the song ‘Paisa Paisa’ from the movie De Dana Dan to personify the new-age Laila.

Month of July brings with it the much awaited rain and cool winds. And after going through the sweltering heat, with temperatures soaring as high as 47 degrees, drizzling rain brings relief to the sun-tanned skin. But that’s not all. Come monsoon and the humidity levels increase, giving rise to myriad skin problems.With increased humidity and heat, our skin becomes more prone to fungal or bacterial infections. Though most of these problems are not serious but the unwillingness to visit a dermatologist can increase the risk and severity of the condition. Also Read – Add new books to your shelfDr Chiranjiv Chhabra, one of the leading dermatologists in India andMonika Sood, MD of TBC by nature has rolled out some easy solutions for you to try out if you come across any of the humidity related problem.Fungal infections like ring worm infection, acne, eczema and folliculitis are common during monssons. The cause of such infections is mostly bacterial or fungal due to excessive sweating, heat, photo-toxic effects of the sun and of course, humidity. Also Read – Over 2 hours screen time daily will make your kids impulsiveSolution: Apply fresh methi paste to the affected area or you can also use turmeric paste to get rid of the fungal infection. To make the paste, take 1-3 tsp of turmeric powder, two table spoon of curd and one table spoon of gram floor. Make a smooth paste and apply it on face for 15 minutes and rinse with lukewarm water.Monsoon makes your oil secreting glands hyperactive. It leads to accumulation of dust and bacterial growth that leads to skin problems like blackheads, whiteheads and pimples. People with normal to dry skin, witness more dryness, as moisture of the skin is hindered due to humidity and heat. Solution: In order to ensure that the oil secretion is under control, use an alcohol free PH neutralizing face wash and wash your face atleast 3 times a day. Also, you can prepare a face pack made of two tablespoon of curd, two drops of lavender oil and one tablespoon of aloevera gel. Apply this pack and wash it after 20 minutes. Curd helps in d-tan and removes blemishes. Aloevera smoothens skin and lavender oil boosts rejuvenation.Excessive hair fall and increased dandruff are also some of the major concerns during monsoon. Humidity and heat results in weakening of hair follicles, resulting in hairfall. Leaving the scalp wet for a long time facilitates growth of dandruff. Whereas, dandruff flakes can fall on the face and aggravate acne.Solution: Dryness can increase manifolds due to constant sweat, which, in turn makes the scalp void of natural oils. Apply lemon juice to the scalp and massage and leave it for 5 minutes. Shampoo and wash your hair with cold water. You will definitely see results in a few days.All the above stated skin problems are common in cities such as Delhi, where pollution levels are unreasonably high and monsoon marks as the most vulnerable time for our skin and hair.
Come January and Shankar’s famed novel ‘Chowringee’ is coming alive through a new film ‘Shah Jahan Regency’, directed by Srijit Mukerji. The story revolves around a hotel named ‘Shah Jahan Regency’ and the lives of people associated with that hotel. The hotel is one of a kind and very different from others as it strongly believes in the rich culture of India and tries to imply and maintain that in every aspect of it- starting from the decor to uniforms of the staff members, to the names given to various parts of the building. The film marks Srjit’s debut collaboration with SVF as a producer under Mathcut Productions. Also Read – Add new books to your shelfThe ensemble cast includes Abir Chatterjee, Parambrata Chattopadhyay, Rituparna Sengupta, Swastika Mukherjee, Anirban Bhattacharya, Anjan Dutt, Mamata Shankar, Rittika,Rudranil Ghosh, Sujoy Prasad Chatterjee, Kanchan Mullick, Babul Supriyo and others. The script, screenplay, and dialogues are by Srijit Mukherji, music is by Anupam Roy and the background score is given by Indraadip Dasgupta. The trailer begins with the dulcet voice of Anjan Dutt who narrates the following poem which sums up the feel of the audio-visual: Also Read – Over 2 hours screen time daily will make your kids impulsive”Our life is but a winter’s day: Some only breakfast and away; Others to dinner stay and are full fed; The oldest man but sups and goes to bed; He that goes soonest has the least to pay.” We see an intricate maze of characters intertwined with one another initially in a simple way which then leads to various complications. Speaking about the collaboration, Srijit Mukherji said, “I have been associated with SVF since 2010 as a director which marked my entry in the Bengali film industry. This is the first time I am not only directing but also co-producing a film, so Shah Jahan Regency has been treated in a special way. The concept is also quite interesting as the entire film is shown in chapters showcasing the attachment of the characters with the hotel, which is more than just a hotel for them.” The film is releasing on January 18, which will be the first release of 2019 from SVF.
