World's first rollable touch-screen tablet developed

Toronto, Sept 5: In a first, scientists have developed a rollable touch-screen tablet - taking inspiration from ancient scrolls to create a modern-day device.

The device, called MagicScroll, is comprised of a high-resolution flexible display that can be rolled or unrolled around a central, 3D-printed cylindrical body containing the device's computerised inner-workings.

Two rotary wheels at either end of the cylinder allow the user to scroll through information on the touch screen. When a user narrows in on an interesting piece of content that they would like to examine more deeply, the display can be unrolled and function as a tablet display.

Its lightweight and the cylindrical body makes it much easier to hold with one hand than a traditional tablet. When rolled up, it fits into your pocket and can be used as a phone, dictation device or pointing device.

"We were inspired by the design of ancient scrolls because their form allows for a more natural, uninterrupted experience of long visual timelines," said Roel Vertegaal, a professor at the Queen's University in Canada.

The MagicScroll's scroll wheel allows for infinite scroll action for quick browsing through long lists.

"Unfolding the scroll is a tangible experience that gives a full-screen view of the selected item. Picture browsing through your Instagram timeline, messages or LinkedIn contacts this way," Vertegaal said.

Beyond the innovative flexible display, the prototype also features a camera that allows users to employ the rolled-up MagicScroll as a gesture-based control device -- similar to that of Nintendo's 'Wiimote'.

The device's rotary wheels contain robotic actuators that allow the device to physically move or spin in place in various scenarios, like when it receives a notification for instance.

"Eventually, our hope is to design the device so that it can even roll into something as small as a pen that you could carry in your shirt pocket," said Vertegaal.

"More broadly, the MagicScroll project is also allowing us to further examine notions that screens don't have to be flat, and 'anything can become a screen'," he said.

Twitter has joined efforts to do away with racially loaded terms such as master, slave and blacklist from its coding language in the wake of the death of African-American George Floyd and ensuing Black Lives Matter protests.

The project started even before the current movement for racial justice escalated following the death of 46-year-old George Floyd in police custody in May.

The use of terms such as "master" and "slave" in programming language originated decades ago. While "master" is used to refer to the primary version of a code, "slave" refers to the replicas. Similarly, the term "Blacklist" is used to refer to items which are meant to be automatically denied.

The efforts to change these terms in favour of more inclusive language at Twitter were initiated by Regynald Augustin and Kevin Oliver and the microblogging platform is now backing their efforts.

"Inclusive language plays a critical role in fostering an environment where everyone belongs. At Twitter, the language we have been using in our code does not reflect our values as a company or represent the people we serve. We want to change that. #WordsMatter," Twitter's engineering team said in a post on Thursday.

As per the recommendations from the team, the term "whitelist" could be replaced by "allowlist" and "blacklist" by "denylist".

Similarly, "master/slave" could be replaced by "leader/follower", "primary/replica" or "primary/standby".

Twitter, however, is not the first to start a project to bring inclusivity in programming language.

According to a report in CNET, the team behind the Drupal online publishing software started using "primary/replica" in place of "master/slave" as early as in 2014.

The use of the terms "master/slave" was also dropped by developers of the Python programming language in 2018.

Now similar efforts are underway at Microsoft's Github and LinkedIn divisions as well, said the report.

Mumbai, Jun 12: Following an overwhelming response for the mega rights issue of Mukesh Ambani-owned Reliance Industries, the partly paid-up rights shares are set to debut on stock exchanges on June 15.

The biggest ever Rs 53,124 crore rights issue was subscribed 1.59 times and received bids worth Rs 84,000 crore on June 3.

Reliance said the rights issue saw a huge investor interest, including from lakhs of small investors and thousands of institutional investors, both Indian and foreign.

In 2019, Ambani said in the Reliance's annual general meeting that the company will be net zero debt by March 2021. The company is on course to achieve its target ahead of the deadline.

"In spite of the COVID-19 crisis and the lockdowns, the due-diligence by Saudi Aramco for the planned investment in the O2C business is on track as both the parties are committed and actively engaged," he said recently.

"With a strong visibility to these equity infusions, Reliance is set to achieve net zero debt status ahead of its own aggressive timeline. We believe rights issue was a part of the company's strategy of deleveraging its balance sheet," said Ambani.

New Delhi, Mar 14: Excise duty on petrol and diesel was on Saturday hiked by ₹3 per litre as the government looked to mop up gains arising from fall in international oil prices.

Special excise duty on petrol was hiked by ₹2 to ₹8 per litre incase of petrol and to Rs 4 incase of diesel, an official notification said.

Additionally, road cess on petrol was raised by ₹1 per litre each on petrol and diesel to ₹10.

The increase in excise duty would in normal course result in a hike in petrol and diesel prices but most of it would be adjusted against the fall in rates that would have necessitated because of slump in international oil prices.
