Unlike the current generation of virtual reality headsets that use a smartphone as the engine and screen, Apple's device will have its own display and run on a new chip and operating system, according to people familiar with the situation. The development timeline is very aggressive and could still change, said the people, who requested anonymity to speak freely about a private matter.
While virtual reality immerses the user in a digital world, augmented reality overlays images and data on the real one. The applications for AR are endless, from a basketball fan getting stats while watching a game to a mechanic streaming instructions on how to fix a specific piece of equipment. Apple isn't the only company working on the technology. Google, which drew derision for $1,500 smart glasses a few years ago, is developing a business-oriented variant. Startup Meta has developed a headset with a focus on education and medical uses.

The Tiangong-1 space station is expected to make reentry between 43ºN and 43ºS early in 2018 .
The agency will lead an international campaign comprised of a total of 13 space agencies from around the world to track the Chinese space station which has begun its terminal descent towards Earth. The majority of the spacecraft is expected to burn up on reentry to Earth's atmosphere, according to a press release by the ESA.
"Owing to the geometry of the station's orbit, we can already exclude the possibility that any fragments will fall over any spot further north than 43 degrees North or further south than 43 degrees South," says Holger Krag, Head of ESA's Space Debris Office.
These latitudes indicate that Spain, Portugal, Italy, Bulgaria and Greece could all be in the firing line should any larger pieces of debris from the station fail to break up completely in the atmosphere.
Since social engineers have come up with the idea of building new, multi-racial, multi-national, multi-religious, multi-cultural societies, they have encountered the natural barrier: xenophobia, which is another name for in-group loyalty and out-group avoidance. Xenophobia is a biological mechanism imprinted at the genetic level that carries a survival advantage. It tells an individual to create bonds with members of the same group and be on his guard against aliens. 2). To put it in plain language: xenophobia is practised at the very basic personal level each time parents warn their offspring to be wary of strangers: not to open the door to them, not to trust them. So modern social engineers have a problem. They need to overcome this deeply rooted biological barrier.
Recent video from the Robotics Systems Lab shows its robot, ANYmal, summoning an elevator - the latest achievement from the four legged bot that has been under development for more than a year now.
Anymal uses one of its legs to reach the elevator button and then trots right in. The button is localized with help of a QR tag.
A mission to the Red Planet is fraught with technical challenges, but the real difficulties may lie in getting astronauts their with their minds intact.
Alarming new research, funded by Nasa, has found that microgravity causes the brains of astronauts to shift upwards and become squashed at the top of their skulls, piling pressure on vital neural regions.
Crucially, the parts of the brain that are most affected - the frontal and parietal lobes - control movement of the body and higher executive function, which are essential for attention, focus, planning, organising and remembering details.

Lockheed Martin is working to develop a high-power fiber laser for fighter jets. Under a $26.3 million contract from the Air Force Research Lab, the firm will design and produce a directed energy system for aircraft, with plans to test it by 2021. Artist's impression pictured.
Under a $26.3 million contract from the Air Force Research Lab, the firm will design and produce a directed energy system for aircraft, with plans to test the technology by 2021.
The move comes after a series of successful tests with similar systems in ground-based platforms - but, the experts say developing a laser for a smaller, airborne design will be a challenge.
The AFRL awarded the contract as part of its Self-protect High Energy Laser Demonstrator program.
This program includes three subsystems, addressing beam control to direct a laser to the target, a pod mounted on the jet to cool the laser, and the laser itself.

The language you use can show how stressed you are better than your own rating of your anxiety, new research shows. Psychologists found that tracking the use of certain words by people predicted stress-related changes to their DNA
Psychologists found that tracking certain words used by volunteers in randomly collected audio clips reflected stress-related changes in their gene expression. The speech patterns predicted those physiological changes more accurately than speakers' own ratings of their stress levels.
The research, which is published on 6 November in Proceedings of the National Academy of Sciences1 suggests that changes in language may track the biological effects of stress better than how we consciously feel. It's a new approach to studying stress, says David Creswell, a psychologist at Carnegie Mellon University in Pittsburgh, Pennsylvania, and one that "holds tremendous promise" for understanding how psychological adversity affects physical health.

Created using hundreds of satellite radar images of the country, the map covers movement over a two-year period from 2015 to 2017.
It shows that small but significant rates of land motion are occurring across almost the entire landscape of Scotland, especially in old mining areas, which could even result in minor earthquakes.
'There are many things that cause the land to move - some are natural and some are man-made', Dr Andy Sowter, chief technology officer of Geomatic Ventures Limited, the company that processed the images, told MailOnline.
'In places like the Scottish midlands they were coal mining for 150 years and that deep coal mining has caused the land to move in a number of ways', Dr Sowter said.
As well as being caused by historical coal mining, this movement is also influenced by subsidence over peat-lands and landslides on steep slopes.
Dr Sowter said there are many reasons why we should be worried about this land motion.
BBC Radio Scotland's Time Travels programme has now unmasked her face by working with a forensic artist at the Centre for Anatomy and Human Identification at the University of Dundee.
The team believes it is likely to be the only accurate likeness of a Scottish "witch" in existence as most were burned, destroying any hope of reconstructing their faces from skulls.
Presenter Susan Morrison said: "It was a truly eerie moment when the face of Lilias suddenly appeared.
When multiple exposures obtained at different times were stacked together to produce the image above, the asteroids showed up as trails because they had moved between exposures, and some of the asteroids were spotted more than once. The five new asteroids orbit within the asteroid belt between Mars and Jupiter. Previous studies missed them because they're extremely faint.
