POSTER: computer news   ||   HELMET QUALCOMM VR820 VIRTUAL REALITY DISPENSES WITH WIRES AND SMARTPHONE

DATE:2016-09-02

Of course,  IFA 2016 exhibition in Berlin could not do without the demonstration of virtual reality devices, and a couple of events exhibits proved that "frames for smartphones" and connected to the PC performance helmets have a real alternative in the form of a third class  devices.  For example, , Qualcomm's Corporation demonstrated at IFA 2016 VR820 reference platform for creating virtual reality helmets Forces party.  In fact, Qualcomm requested the release of the standard version of the helmet Goertek, a US developer partners can offer their own variations on this theme in the next year.  This business model simplifies the entry of new players on the market: the bulk of the work has already been done by Qualcomm.

Helmet Qualcomm VR820 virtual reality based on the Snapdragon processor 820, as you might guess from the name.  It is running the operating system Android M and Tango programming environment allows it to track the user's position and his head on the six coordinate axes (three linear and three angular) with built-in sensors.  The helmet does not require connection to a desktop PC or a Smartphone installation, it is self-sufficient in their work, it does not need any external sensors.  Two cameras are directed forward, they can be used for augmented reality applications and for gesture recognition.  Two other cameras monitor the user's pupils - this allows  to selectively pick out a higher detail .

AMOLED type display device produces Samsung.  released picture with a resolution of 1440 x 1440 pixels and a refresh rate of 70 Hz for each eye.  The speed of the helmet on the user's reaction movement - not more than 18 ms.  In the current version the battery charge is enough for a couple of hours.  Manufacturers of serial devices can improve this figure.  It is expected that this helmet will cost not less than $ 600.

HELMET QUALCOMM VR820 VIRTUAL REALITY DISPENSES WITH WIRES AND SMARTPHONE

POSTER: computer news   ||   TWO YEARS LATER, FLASH MEMORY ON NANOTUBES WILL BECOME A REALITY

DATE:2016-09-02

Recently, two Japanese companies  share interesting news.  Development company Fujitsu Semiconductor and contract manufacturer company Mie Fujitsu Semiconductor announced the acquisition of a license for the development and production of non-volatile memory on carbon nanotubes - NRAM.

US company Nantero (Woburn, MA) is developing Memory NRAM for about 15 years .  By 2006 Nantero patented technology to use nanotubes in the process of manufacturing ICs using conventional CMOS process technology.  This application of nanotubes on the plate, removal of impurities and others.  By 2015, the company launched the production of memory technology licensing NRAM and at that time held the technology tests at the plants of two major chip manufacturers with a worldwide reputation.  One of these companies was Fujitsu.

Fujitsu has received a license for commercial release NRAM memory using 55-nm process technology in the future will develop NRAM production within the 40-nm process technology.  To produce chips with smaller norms Fujitsu does not know how.   

Fujitsu intends to launch itself NRAM release in two years, but only in the form of built-in memory LSIs.  After that it will be launched production of individual chips and related NRAM memory or storage.  The company has vast experience in the production of FeRAM memory, which it intends to move to the memory production NRAM.  Unlike FeRAM, NRAM memory promises a more dense placement of cells and better scaling when changing process technology.

Among other advantages, we note NRAM record even for DRAM performance: switching speed of the cell from one state to another is 20 picoseconds, and write speed - 5 ns.  This NRAM cell consumes very little energy, stores data without the support of power and can withstand the number of rewrite cycles 10 to 11 degrees.  In practice - this is eternity.  According to the developers, conducted adaptation NRAM chips to create DDR4 memory modules.  It will be chips with 4-8 layers and a capacity from 8 to 32 Gbps.  Potentially, this memory can be replaced in the future DRAM and NAND-flash.  According Nantero leadership, the company has 12 clients who are interested in technology NRAM and some of them belong to the leaders of the semiconductor memory market.

Briefly recall that NRAM cell - a mechanical switch, in which the toggle role carbon nanotubes.  Under the influence of the voltage control tube deform or tear and create a conductive circuit within the cell.

TWO YEARS LATER, FLASH MEMORY ON NANOTUBES WILL BECOME A REALITY

POSTER: computer news   ||   ALCATEL DEMONSTRATES THE VIRTUAL REALITY HELMET AND PANORAMIC CAMERAS TO SMARTPHONES

DATE:2016-09-02

Alcatel at the IFA 2016 provide its own virtual reality helmet Vision, which is, in fact, self-contained unit with a smartphone.  Eight-core processor got three gigabytes of RAM and a 32 GB solid-state memory, Bluetooth and LTE wireless interfaces, as well as a full set of necessary for tracking user movements sensors - at least in the understanding of smartphone maker.

Couple AMOLED-display with a diagonal measurement of 3.8 "has a resolution of 1080 x 1020 pixels each, sharpness is adjusted for each eye separately, so the helmet can be used without glasses with diopters or contact lens viewing angle provided by the device -. 120 degrees, and the delay does not exceed 17 ms. in the back of the helmet is placed battery capacity of 3000 mA h, a charge which should be enough for two or three hours of continuous operation. Alcatel Vision will cost about $ 600, on sale it will arrive at the end of this year or early next year, depending on the region .

Alcatel also provides  two panoramic camera 360 with a pair of wide-angle lenses (210 degrees), which may have two design versions - in case a round or square, respectively.  The camera allows  to take a photo sphere when connected to any of the three smartphones Alcatel: IDOL 4S, IDOL 4 or POP 4S.  Connection is made via the micro-USB port, but the camcorder's compatibility with smartphones of other brands do not have any information.  Most likely, everything depends on the firmware application that allows for panoramic shooting.  Once it appears, Alcatel's 360 camera can be used with any smartphone, equipped with a micro-USB port.  As a rule, Alcatel's 360 camera will be sold bundled with smartphones of the brand, it can be purchased separately for about $ 100.

POSTER: computer news   ||   BULGARIAN DEVELOPERS ARE READY TO UNTIE HELMET HTC VIVE WITH THE COMPUTER

DATE:2016-09-02

The founder of Oculus VR Lucky Palmer in one of his interviews said that the future of virtual reality for wireless devices that do not require connection to a PC via cable.  In the meantime, the priority is to provide entertainment with minimum delay to the movement of the user, a wired connection is still some awkward attribute Oculus Rift.

In the case of competing helmet HTC Vive, however, according to the Bulgarian developers of Quark VR, you can switch to a wireless interface.  At least, the Bulgarian enthusiasts are already developing worn on a belt or pocket adapter to which the standard HTC Vive helmet can be connected without the need for a direct cable connection with a computer.  The communication between the adapter and PC will be conducted on the interface Wi-Fi.

The developers claim that the impact of the wireless interface on the delay in the exchange of information could be minimized.  adapter prototype will demonstrate in action this autumn.  Apparently, the device will contain a battery, since the helmet HTC Vive gets power through a cable.
