Cuttable, Foldable Sensors Can Add Multi-Touch To Any Device

coverHP
Researchers at the MIT Media Lab and the Max Planck Institutes have created a foldable, cuttable multi-touch sensor that works no matter how you cut it, allowing multi-touch input on nearly any surface.
In traditional sensors the connectors are laid out in a grid and when one part of the grid is damaged you lose sensitivity in a wide swathe of other sensors. This system lays the sensors out like a star which means that cut parts of the sensor only effect other parts down the line. For example, you cut the corners off of a square and still get the sensor to work or even cut all the way down to the main, central connector array and, as long as there are still sensors on the surface, it will pick up input.

The team that created it, Simon Olberding, Nan-Wei Gong, John Tiab, Joseph A. Paradiso, and Jürgen Steimle, write:
This very direct manipulation allows the end-user to easily make real-world objects and surfaces touch interactive,
to augment physical prototypes and to enhance paper craft. We contribute a set of technical principles for the design of printable circuitry that makes the sensor more robust against cuts, damages and removed areas. This includes
novel physical topologies and printed forward error correction.
You can read the research paper here but this looks to be very useful in the DIY hacker space as well as for flexible, wearable projects that require some sort of multi-touch input. While I can’t imagine we need shirts made of this stuff, I could see a sleeve with lots of inputs or, say, a watch with a multi-touch band.
Don’t expect this to hit the next iWatch any time soon – it’s still very much in prototype stages but definitely looks quite cool.

RAWALPINDI: Chief of Army Staff General Ashfaq Parvez Kayani said on Friday that the accusations made by the Indian military against Pakistan Army were unfortunate, unfounded and provocative, and that Pakistan’s restraint should not be exploited for levelling baseless allegations that harm prospects of peace.
According to a press release issued by Inter Services Public Relations (ISPR), the comments of the Indian Army Chief alleging that Pakistan Army and Inter-Services Intelligence (ISI) supported a recent militant insurgency in Keran sector of Indian administered Kashmir, were described by Kayani as unfortunate, unfounded and provocative.
The army chief said that he was concerned about the continued violations along the Line of Control from across the border. He proposed that India should reciprocate Pakistan’s suggestion of holding either a joint or an impartial investigation, preferably by the United Nations, into the LoC incidents.
“Pakistan Army was exercising restraint but the same should in no way be used as a pretext for leveling such baseless allegations that vitiate prospects of regional peace.”
Addressing a group of officers at General Headquarters, the COAS reiterated that the Pakistan Army was fully supportive of the peace process initiated by the government.

Did you know?: Aamir Khan buys flat worth INR600 million!


Bollywood superstar Aamir Khan has a new address. The actor has apparently bought a new apartment on Carter Road in Bandra, Mumbai, where he was staying for the last few months on rent. It seems he fell in love with the place as he ultimately decided to buy it. According to Mid Day, the place is worth a whopping INR600 million!
The flat is double-storey, faces the sea and is 5,000 square feet. Khan’s previous place of residence was under renovation so he decided to move into this new flat and was paying a monthly rent of INR1 million. He later expressed a desire to buy the two-floor apartment.
His wife and film-maker Kiran Rao seems to also love this new roomy apartment, according to the Times of India.

Ali Zafar injured filming in Bangkok

Luckily there was no serious or permanent damage and the actor returned on set after doctors stitched up his cut. PHOTOS: PUBLICITY
Singer-turned-actor Ali Zafar sustained an injury while he was filming in Bangkok, The Express Tribune learnt on Friday.
According to his publicist, Ali was at a shoot in Bangkok for a multinational brand when he cut his face and was rushed to the hospital.
Ali’s stunt double was supposed to perform a sequence, but didn’t quite resemble the current long-hair and French beard Ali is sporting for his next feature Kill Dill. For this reason, Ali decided to do his own stunt, during which he injured his face.
Luckily there was no serious or permanent damage and the actor returned on set after doctors stitched up his cut.

Teacher training: Most teachers get zero for English

According to the assessment, 30% of government and 22% of private teachers are at the beginner’s level for English A1. PHOTO: FILE
LAHORE: 
More than half of teachers in public primary and middle schools, and an even higher proportion of private school teachers, lack basic knowledge of English, even the ability to understand and use simple phrases, according to research conducted earlier this year.
The findings are part of a report – titled ‘Can English Medium Education Work in Pakistan? Lessons from the Punjab’ – that assesses the abilities of more than 2,000 teachers at public and private primary and middle schools.
According to the report, 56% of teachers at public primary and middle schools have “no measurable standard of functional language ability”. The situation in private schools, according to the report, is even worse, with 62% of teachers lacking basic knowledge of the language.
The Punjab government announced in 2009 that English would be the medium of instruction in all government schools in the province. The British Council and the Schools Education Department launched the Punjab Education and English Language Initiative (Peeli) earlier this week to address this shortcoming.
Findings
The report contains research conducted by the British Council, the Directorate of Staff Development (DSD) and the Idara-i-Taleem-o-Agahi, with support from the Punjab Education Foundation. The researchers surveyed more than 2,000 teachers from March 27 to April 23 this year, assessing speaking, listening, reading and writing skills.
It rates the teachers’ abilities on the Common European Framework of Reference for Languages (CEFR) scale. According to the assessment, 30% of government and 22% of private teachers are at the beginner’s level for English A1. Twelve per cent of private and government school teachers fall in category A2, also called the pre-intermediate level. And 3% of private and 2% of government teachers are in the B1 category, or the first level of the intermediate bracket.
During the course of the study, a new A0 level was established for those with no measurable standard of functional language ability. Fifty-six per cent of government teachers and 62% of private teachers were found to be in this category.
Things were slightly better at the middle school level than the primary school level, with 38% of middle teachers and 65% of primary teachers judged to be in the A0 category. Almost 94% of teachers at English medium schools were deemed to be in the pre-intermediate (A2) or lower levels (A1 or A0) of English language ability.
Training
“While the government took the leap of imposing English as the medium of instruction in view of the disparity between private and government schools, the ground reality is that teachers are not equipped to deal with this change,” says Soper Bhat, a training and development consultant with the Peeli project.
Bhat says that the need for extensive training became obvious last year, when the British Council assisted the DSD with the Primary English Teacher Training project. Some 28,000 teachers were trained in the first batch starting in February 2012, and another 30,000 over the last summer.
“We found out that teachers didn’t even know the language. They needed to learn English before teaching it in the classrooms,” she says.
This is where Peeli, a five-year programme that aims to train 330,000 teachers for the potential benefit of 15 millions students, comes in. The British Council resource centre in Lahore will be at the centre of the training regime, while digitally connected to DSD centres all over the province that will host the training sessions for the teachers.
Besides improving language skills, the training also seeks to impart innovative teaching methodologies that make learning fun and engaging, says Bhat.
“For this we will train teachers using the same methods we will ask them to introduce in the classrooms. After experiencing it themselves, they will understand the value of the techniques.”
She adds that the training will not just help students in getting better teachers. “For higher education, a good understanding of the English language is imperative. Also, for teachers, it will help them gain access to better employment opportunities,” she says.

Dedicated public servant: First female ASP from lower Sindh ready to clean house

My parents' dedication to my educational pursuits paid off, says ASP Suhai Aziz Talpur .
KARACHI: 
ASP Suhai Aziz Talpur, the first woman from lower Sindh to join the police at this rank, was once shunned by her relatives. And only because her parents thought she deserved to be educated.
“When my parents decided to enroll me at a school, most of our relatives started taunting my family. So much so, that my family had to leave our village and move to a nearby town,” she recalled. “But the moment I cleared my Central Superior Services (CSS) exams and was told that I’d be joining the police department as an assistant superintendant police (ASP), the same people started approaching me by claiming to be my long-lost relatives. This is the power of education and being a female, I am proud to have this power.”
At the age of 25, Suhai will be the first woman from lower Sindh [Thatta, Badin, Tando Muhammad Khan, Mirpurkhas, Umerkot and Tharparkar districts] to join the police in November. “My first preference was district management group and the police force was second. My percentage in the exams, however, qualifies me to join the police force. I know the uniform has its own power and I will try my best to use it for good.”
Strong roots
Suhai belongs to a lower middle class family of Bhai Khan Talpur village in Tando Muhammad Khan district. Her father Aziz Talpur, a political activist and writer, always dreamt big for his daughter. “My relatives cut off ties with me because I wanted Suhai to study as they were only in favour of religious education,” Aziz told The Express Tribune. “But I vowed to provide my daughter quality education. Now I know my efforts were successful.”
Suhai started her primary education at a private school in Tando Muhammad Khan and joined Bahria Foundation for her intermediate studies.
Her educational path then led her to pursue BCom from the Zubaida Girls College, Hyderabad. “My family wanted me to become a chartered accountant but I found the job to be very dull as it had no social value,” she said. “That is when I appeared for CSS and cleared it in first attempt.”
She credited her success to hard work and her upbringing. “My parents are nationalists. As a child, they used to emphasise that I memorise Sindhi poetry. This developed my interest in literature and history, leading me to secure top marks in both the subjects in the CSS exams.”
(Un)suitable candidates
Although small in number, female officers have managed to make it to the top on their own.
Earlier, only two women in Sindh cleared the CSS and were working in the police department on senior posts – ASP Irum Awan and Shehla Qureshi.
Awan was the first female ASP to be posted in Ghotki, a district known for tribal clashes and dacoit culture. “I worked hard to stop honour killings as I could understand the plight of the victims,” she said.
Three other female officers enjoy senior positions but they joined through the Sindh Public Service Commission (SPSC) or were political appointees. Naseem Ara Panhwar, from Mirpurkhas, serves as the SSP in the driving licence branch. She was appointed in 1995 when the Pakistan Peoples Party-led government had directly recruited DSPs in the police through the SPSC. “It’s a tough but appealing job,” she said. “More young and vibrant women should come forward because not only do they have equal potential as their male counterparts but they would also be in a better position to solve women’s issues.”
SP Traffic Jalees Fatima and Establishment ADIG Noushaba Kausar are two other female officers who have been given high ranks in the department.

Showdown: 4K vs. Blu-ray movies

So far, we have seen enough 4K demonstration clips from the various TV makers to know that they looked absolutely breathtaking on all ultra high-definition (UHD) TVs. But can the same level of clarity be expected for actual 4K movies, which are not shot to deliberately show off the panels' higher resolution? Not to mention, many movies are also shot to retain a softer "film look" unlike these crisp and highly sanitized promotional materials.
While we didn't manage to secure a Sony FMP-X1 UHD player loaded with 4K Hollywood films, we were able to loan a signal generator from the company instead. Preloaded in the machine are snippets of two native 4K movies, After Earth and Total Recall. Granted, these sample clips are not the actual full-length films and may not accurately represent most 4K movies, but they do offer a glimpse of what we can expect.

After Earth

This is how After Earth looks like on a Sony Bravia KD-65X9004 UHD TV. All screenshots were taken via a Canon EOS 600D dSLR fitted with an EF 23-105mm F4 L lens at ISO100. Note that these images have been cropped and resized from the original pictures. No additional sharpening were applied.

There are plenty of fine details to feast your eyes in this particular scene, especially with the dense vegetation.

Total Recall

For Total Recall, we were also able to compare between the 4K and Blu-ray versions using an LG 65LA9700 and 55LM9600, respectively. Both sets feature similar LED-backlighting, which should minimize any variation in terms of screen contrast.

This scene depicts an expansive cityscape, which is an excellent test of clarity between the 4K and Blu-ray formats.

Besides a clear difference in pixel size and density, the signboard and tray-like object are also clearer in 4K.

Pretty much the same observation with the earlier close-up, except that the 4K appears a tad sharper, too.

We continue with the pixel peeping, but switched to this particular night scene with many high contrast portions.

Both signboards rendered in 4K are generally more defined. Can you also see a brown line touching the letter A, too?

4K offers slightly better clarity again, while jaggies can be observed on the lower part of the 1080p version.

Good, but can be better

Having compared these footages extensively, the differences between native 4K and Blu-ray films are surprisingly subtle. Putting aside a marginal improvement in sharpness and clarity, you are unlikely to tell both video formats apart at a glance. Bear in mind that 4K is only four times better than Blu-ray in terms of resolution, while Blu-ray is a six-fold improvement over the DVD format.
Still, future 4K movies, whether they are available in 4K Blu-ray discs or broadcasted, can probably offer more than better image clarity. There is also the possibility of a smoother 60fps motion supported by HDMI 2.0 and richer hues proposed by the Rec. 2020 standard.
Here's another article illustrating the impressive video-upscaling performance of many UHD TVs, which are touted to offer comparable picture quality to full-HD TVs for Blu-rays and DVDs. However, with UHD panels priced at a premium, you’re probably better off with a standard full-HD TV to display these non-4K content, for now
