Samsung launches Galaxy Round, world's first smartphone with curved display .. !!

Samsung Electronics Co Ltd on Wednesday launched the world's first smartphone with a curved display, a variant of the Galaxy Note which moves the Asian giant a step closer to achieving wearable devices with flexible - even unbreakable - screens. 
Curved displays are on the frontlines of Samsung's innovation war with rivals such as Apple Inc and LG Electronics Inc, as the South Korean firm seeks to expand its lead in the slowing market for high-end smartphones.

"It's a step forward for having unbreakable gadgets and flexible devices eventually. But for now, the new phone is more of a symbolic product," said Hana Daetoo Securities analyst Nam Dae-jong, adding that Samsung did not yet have capacity for large-scale production of curved touch-screens for the new Galaxy Round.

The Galaxy Round is Samsung's attempt to gauge consumer appetite for curved phones although its lack of other eye-catching features means it is unlikely to be a hit, he said.

"I don't think it'll be massively compelling enough for gadget buyers as ... the curved display doesn't come with many unique features," he said.

The Galaxy Round's 5.7-inch (14.4-centimetre) display has a slight horizontal curve and weighs less than the Galaxy Note 3, allowing a more comfortable grip than other flat-screen models on the market, Samsung said in a statement.

Its key features include a tilt function which allows users to check information such as missed calls and battery life, even when the home screen is off. Users can also scroll through media files by pressing the screen's right or left, the company said.

The phone initially would be available only in South Korea and no decision had been made about releasing it in other markets.

Design challenges

Curved displays open up possibilities for bendable designs that could eventually transform the high-end smartphone market, where growth has slowed amid competition from low-end producers.

Samsung's Galaxy Gear smartwatch released last month has a flat screen, but the company is hoping to have the technology to make more attractive and wearable devices in what is shaping as a key battleground for consumer electronics companies.

Technology firms have yet to figure out how to cheaply mass produce the parts and come up with display panels that can be thin and heat-resistant. Batteries also have to take new forms to support flexible screens that can be rolled out, attached to uneven surfaces or even stretched. The battery in the Galaxy Round is not curved, Samsung said.

Samsung's new curved-screen phone, available through South Korea's biggest mobile carrier SK Telecom Co Ltd, costs 1.089 million won.

How to type like an expert using keyboard

BERLIN: A German scientist has developed asoftware which assists users in identifying and learning keyboard shortcuts so they can become as fast as expert users.

If somebody wants to shift text elements within a Word document from one position to another, he usually uses the mouse. This procedure is rather cumbersome for the user, since he first needs to click and highlight the text element before he can put it at the appropriate place.

The user could avoid such complications by using a few shortcut keys, so-called hotkeys, instead. However, users frequently do not know enough keyboard shortcuts to work with them efficiently, or are not aware of the available combinations.




Gilles Bailly, researcher at the Max Planck Institute for Informatics and the Cluster of Excellence at Saarland University in Germany wants to increase the use of hotkeys among less-experienced users and help them maximise expert performance by using consistent shortcuts.

To accomplish this, Bailly developed a special interface mechanism in collaboration with other researchers from several universities. It enables hotkey browsing, supports physical rehearsal and assures rapid hotkey identification.

"To see the hotkeys, the user needs to press a certain key button," said Sylvain Malacria from the University of Canterbury in New Zealand.

He calls this special key the modifier. On an Apple keyboard, this function is taken by the command key; at a Windows computer, by the control key.

As soon as the user has pressed the modifier, the software overlaps the icons on the screen, as for example all the symbols in a toolbar for a Word document, with shortcuts for a few seconds.

Thus, the interface mechanisms shows small boxes in which every equivalent keyboard shortcut is displayed. In doing so, users who rarely use the computer are given the essential hints to apply the shortcuts until they know them by heart.

The programme supports them by proposing the hotkeys very quickly; they need only press the modifier key. To use the shortcuts more generally, the user frequently has to repeat the same finger moves. In this way, the user keeps remembering the key combinations.

"If the user is in the middle of a workflow, he does not need to remove his hands from the keyboard and reach for the mouse. He is able to enter his commands into the computer directly," said Bailly.
