Global smartphone market to shrink in 2019.

The global smartphone market is expected to shrink further in 2019 due to weaker demand and other unfavourable factors, a report said on Tuesday.

Global smartphone production is expected to reach 1.41 billion units this year, down 3.3 per cent from the previous year, according to the report from TrendForce, a leading market intelligence provider.

Replacement demand is likely to slacken this year due to a lack of devices with landmark functions, TrendForce said, adding global smartphone output could drop as much as 5 per cent on-year due to the uncertainty and fallout from the ongoing trade war between the US and China, Yonhap news agency reported.

Samsung Electronics Co is projected to grab the leading market share of 20 per cent this year, followed by Huawei with 16 per cent and Apple Inc with 13 per cent.

Among the top three industry players, Huawei will likely become the only company to post positive growth in smartphone production.

Samsung Electronics Co is projected to grab the leading market share of 20 per cent this year, followed by Huawei with 16 per cent and Apple Inc with 13 per cent.

Samsung’s smartphone output is predicted to shrink 8 per cent on-year to 293 million units, with Apple’s production likely to fall 15 per cent to 189 million.

Earlier, another industry tracker, Strategy Analytics, predicted global smartphone shipments to come to 1.43 billion this year, down 0.6 per cent from a year earlier.

Strategy Analytics forecast a market share of 20.3 per cent for Samsung, 16.1 per cent for Huawei and 14.4 per cent for Apple.

TrendForce said Samsung will likely take a more aggressive strategy in terms of price and specifications as the company finds it hard to tap new business areas.

Samsung plans to roll out its Galaxy M mid-range and low-end smartphones in India at the end of this month and unveil its Galaxy S10 flagship smartphone and foldable smartphone in San Francisco next month in a bid to create new demand and outperform Chinese rivals. (IANS)

Researchers Develop System That Can Locate Shooters Using Smartphone Video

Specifically, the system looks at the time delay between the crack caused by a supersonic bullet's shock wave and the muzzle blast, which travels at the speed of sound

By using Video from three or more smartphones, the direction from which the shots were fired -- and the shooter's location -- can be calculated based on the differences in how long it takes the muzzle blast to reach each camera. Pixabay

Researchers have developed a system that can accurately locate a shooter based on Video recordings from as few as three smartphones.

The system, called Video Event Reconstruction and Analysis (VERA), won’t necessarily replace the commercial microphone arrays for locating shooters that public safety officials already use, although it may be a useful supplement for public safety when commercial arrays aren’t available.

“One key motivation for assembling VERA was to create a tool that could be used by human rights workers and journalists who investigate war crimes, terrorist acts and human rights violations,” study researcher Alexander Hauptmann from Carnegie Mellon University in the US.

When demonstrated using three video recordings from the 2017 mass shooting in Las Vegas that left 58 people dead and hundreds wounded, the system correctly estimated the shooter’s actual location — the north wing of the Mandalay Bay hotel.

The estimate was based on three gunshots fired within the first minute of what would be a prolonged massacre.

VERA uses machine learning techniques to synchronise the video feeds and calculate the position of each camera based on what that camera is seeing.

“But it’s the audio from the video feeds that’s pivotal in localising the source of the gunshots,” Hauptmann said.

Specifically, the system looks at the time delay between the crack caused by a supersonic bullet’s shock wave and the muzzle blast, which travels at the speed of sound.

It also uses audio to identify the type of gun used, which determines bullet speed.

VERA can then calculate the shooter’s distance from the smartphone.

“When we began, we didn’t think you could detect the crack with a smartphone because it’s really short,” Hauptmann said.

“But it turns out today’s cell phone microphones are pretty good,” Hauptmann added.

VERA is not limited to detecting gunshots.

“It is an event analysis system that can be used to locate a variety of other sounds relevant to human rights and war crimes investigations,” Hauptmann said.

The researchers presented VERA and released it as open-source code at the Association for Computing Machinery’s International Conference on Multimedia in Nice, France. (IANS)
