Microsoft HoloLens – The Holographic Computer Headset

Published

on

HoloLens by Microsoft

1) HoloLens is basically a holographic computer built into a headset that lets you see, hear, and interact with holograms within an environment. Microsoft built the headset without the need to be wirelessly connected to a PC, and has used high-definition lenses and sound technology to create that immersive, interactive holographic experience. The HoloLens comes with semi-transparent holographic lenses which ‘generate multi-dimensional full-color holograms’. That means it’s not going to be project  images into a room that everyone can see. Basically HoloLens is a high-tech computer system that can be wear and works according to our gestures with hands, eyes, etc.

Augmented reality(AR) is the mixture of virtual reality(VR) and real life, as developers can create images within applications that blend in with the contents in the real world. With AR, users are able to interact with virtual contents in the real world, and are able to differentiate between the two.

 Invented by Alex Kipman and team.

This is the first holographic computer which is running on Windows 10. It is completely unattached as no wires, phones or computers needed, it is a computer itself. The premier device for Windows Holographic, Microsoft HoloLens is  smart-glasses headset that is cordless, self-contained Windows 10 computer. It uses various sensors, a high-definition stereoscopic 3D optical head-mounted display, and spatial sound to allow AR applications, with a natural user interface that the user interacts with through gaze, voice, and hand gestures. It has Codenamed as “Project Baraboo”. HoloLens has been in development for five years.

1.1 Holographic Technology used :

Holography is a diffraction-based coherent imaging technique in which a complex 3D object can be reproduced from a flat, two-dimensional (2D) screen with a complex transparency which represent amplitude and phase values. It is commonly agreed that real-time holography is the plus ultra art and science of visualizing fast temporally changing 3-D scenes. The integration of the real-time or electro-holographic principle into display technology is best for display.

1.2 How it works :

Microsoft HoloLens has user interface which takes voice, gaze and gestures as input command. Internal computer works on input command. For Projection of hologram, for projection HoloLens use the HUE (head up display) method in which there are 2 Nano projectors are there at each side of head and semitransparent visor which reflect the image as light on users eye. Microsoft explains the holographic element in this way as:

“The key to great holographic experience holograms that are light point rich, i.e. have a high holographic density, and are pinned or anchored to the world around you.”

It is introduce with operating systems, such as Android, iOS and OS X on 5 April 2016.

1.3 It has a major six parts those are

                         Computer, Camera

Lenses, Vent, Sensor, Buttons.

About Camera

The project HoloLens depth camera has a field of vision that spans 120 by 120 degree, there is one 2 megapixel camera for recording videos and  capturing images.

✓ HoloLens is not just a visor connected to a Computer; it is a computer on its own. HoloLens contain Central processing Unit , battery, GPU(graphical processing Unit) and first of its kind HPU (holographic processing unit) which is made by Microsoft itself . There are total 18 sensors fitted the brain of the device with terabyte of data every second.

 ✓ Lenses used –

Microsoft HoloLens has two displays. They are transparent so that User can see the actual world behind virtual object. To create project HoloLens image, light Particles bounce around millions of times in the so called light engine of the device. Then the photons enter the two lenses (one for each eye) and form images on lens

✓ Ventilation used –

The device is more powerful than a laptop but won’t overheat- warm air flows to the sides. They are used to cool the lens.

✓ Sensor used

Sensor track where the user are looking and adjust the display. Motion sensor detects user movement and gesture. The sensor can also see user hands, the hands are an input system: user can interact with whatever he sees by just touching it.

HTC Exodus 1: Blockchain phone specs, price and release date

Published

on

Smartphone manufacturer HTC is taking a major leap into the cryptocurrency ecosystem. They are stepping into the wider blockchain industry. With HTC U12 and U12+ about to be unveiled in a couple of days, HTC has a lot of surprises for its users in its pocket. On 15th of this month, HTC unveiled a website that showcases the HTC Exodus. And HTC unveiled the Exodus today at web3summit.

Furthermore, there is only one company that has completely succeeded in making a fully blockchain powered device. Swiss company Sirin-Labs unveiled there first phone Finney and HTC is joining the race with Exodus. Finney has a 12-megapixel rear camera with low-light f/1.8 aperture and an 8-megapixel 85-degree wide angle front facing the camera. It is powered by a 3,280mAh battery with fast charging support. Connectivity features include Bluetooth 5.0, NFC and LTE, among others. Specs wise the phone packs pretty much enough but what’s worth mentioning is what happens over the internet. The blockchain phone comes with a Qualcomm Snapdragon 845 processor. It has a 6-inch display at 18:9 aspect ratio, 402ppi and 1500:1 contrast ratio. The phone features 128GB built-in storage and 6GB RAM.

The HTC Exodus 1, aka the ‘blockchain phone’, is nearly ready to enter the wild, with the company has now confirmed the specs of its forthcoming cryptocurrency handset. Check out the TEASER.

Overview

Blockchain phones are the new Virtual Reality. Every smartphone manufacturer is going to add something or the other that gets their hands-on in this domain. Huawei is rumored to be working on a secret Blockchain powered device which will have layers of decentralized apps and much more. Samsung has also created a blockchain network but we have no sources claiming a blockchain phone in the making.

The Taiwanese firm unveiled the World’s first native blockchain phone. The tailor-made Android-powered phone will provide support for decentralized applications(DApps). Apps like CryptoKitties, and will feature a secure hardware enclave for users. Now the users will have access to a Universal Cryptocurrency wallet that is native to the device itself.
With over two decades of experience manufacturing the world’s leading smartphones and shipping over 100 million phones, they believe they can help reshape the internet with the HTC Exodus.

Working with multiple protocols with the intent of interoperability between blockchains. increasing DApp user base. Bringing a streamlined mobile user experience to the DApp community. Providing more nodes on the path to true decentralization. We want to double and triple the number of nodes of Ethereum and Bitcoin. To have your identity and data on the phone rather in a centralized cloud and open-mindedness towards the collective wisdom of the crowd.
This is what HTC claims the Exodus can stand up to. The performance will be incomparable with any device of any brand as there aren’t any competitors in this domain of phones.

  • Exodus will have Hardware support for Cryptocurrencies

  • Will support Bitcoin, Litecoin, and Etherum

  • Advanced security features and claims of virtually “tamper proof”

The phone will be compatible with multiple protocols and will exchange and make use of information vividly. Phil Chen who creates HTC’s virtual reality headset Vive is the leader of the Exodus project. HTC is rumored to be working on a VR specific device. HTC has a lot of gaming genre users and this will help them enhance their users’ experience. Still, it is good enough to witness a new and revolutionary phone.

The company wants customers to be able to pay for the phone with cryptocurrencies, but we haven’t received any distinctive details. “We think that the phone can be an agent in the future for decentralization,” said Chen. “We want you to hold your own key [through] a secure management method in our phones.” This is official early access release to the EXODUS 1. They are inviting a community of developers and enthusiasts to work with us to keep building security. Join them in rebuilding trust together, one phone at a time. Get your early access now! Go to www.htcexodus.com now!

 

What exactly HTC wants Exodus to do

Chen, who now holds the title of CDO (Chief Decentralized Officers), is the head of the firm’s crypto and blockchain related initiatives. “Through the Exodus, we are also excited to be supporting underlying protocols such as Bitcoin, Etherum, Dfinity and more,” Chen wrote in a blog post accompanying the announcement. Still, a vast majority of HTC fans want something new and innovative from them in a long time.

He also wrote that “I want to see a world where the end consumers can truly own their data (browsing history, identity, assets, wallets, emails, messaging, etc) without the need for central authorities. There is a lot of work ahead of us, but I believe the mobile hardware layer can contribute significantly to our new decentralized world.” With Facebook’s Data Leak controversies, HTC might end up taking the lead in the smartphone race with this.

I suppose we have to wait for a month or two to get more info on these type of devices. This revolutionary product might change the way we use the internet today. I don’t know exactly if I wanna buy one. It’ll be fun to use DApps and to hover over the decentralized web tbh. If anything does happen to your device, you can breathe easy, as HTC has imbued the Exodus with a social-themed security protocol that sees users nominate several contacts to hold a piece of a unique security key – and only bringing all of these pieces together will unlock the device.

Qualcomm unveils Snapdragon 675 with new Kryo 460 CPU

Published

on

Qualcomm Technologies, Inc. is continuing to bring together global manufacturers and operators, along with software and hardware technology vendors, to strategize and discuss industry trends and technology developments with their Snapdragon chipsets. Mark your calendars for this 3-day event highlighting 5G, connectivity, AI, IoT and so much more. This year’s summit promises to be one of the best ever, featuring wireless leader keynotes, breakout sessions, multiple exhibits and networking events, all showcasing the latest technology, and much more. Qualcomm made a lot of advancements in the last few months. And the tech giant made steady announcements at their 4G/5G Summit at Hong Kong.

Qualcomm 4G/5G Summit at Hong Kong

In the Keynote, Qualcomm’s President Mr. Cristiano Amon talks about how 5G is nearing deployment, with global trials underway and deployments planned in the coming months. He continues about how the next generation of wireless will allow virtually every industry to deliver advanced connectivity and increased intelligence across the rapidly evolving wireless edge. It is essential that the broader ecosystem pursues the wireless and computing technologies that will provide the foundation for the coming transformation. To just have an overview read to it, focus on the key points as per Qualcomm:

  • Qualcomm optimized the Snapdragon 675 for mainstream use.

  • The first smartphones using the Snapdragon 675 will ship in Q1 2019.

  • The Snapdragon 675 is Qualcomm’s third mid-range processor announced within the past six months.

Overview

Qualcomm makes one of the finest processors in the industry and as it turns out they also focus on the mid-range consumers. It comes out on the top with the 710 followed by the 670 in the mid-range category. Now that it is history, Qualcomm announced a new processor in the 600 range. The Snapdragon 675 is a really interesting processor but not for all the reasons you are thinking. In terms of where it fits in the overall Qualcomm’s mid-range processor, is somewhat between the 670 and the 710. And for a little humor, the Snapdragon 675 has got a slightly worse Adreno 612 GPU in it compared to the 615. The Snapdragon 675 has got the same modem as the 670, the exact DSPs and the image processors, but with a bit of enhancement.

Qualcomm 675 chipset launched

So, why is the Snapdragon 675 so interesting? Well, it is using the 4th Generation Kryo 460 CPU Design. And as per our research and Qualcomm’s announcement, no other processor in its lineup uses the 4th Gen CPU. Well, the Kryo core 1st Gen design is found in-house in the Snapdragon 820 and 821. Then the 2nd Gen Kryo which was built with the Cortex technology is found in the Snapdragon 835 and finally, the 3rd Gen is found in Snapdragon 845.

Snapdragon 675 + 4th Gen Kryo Core

Snapdragon 675 is basically a Cortex A76 coupled together with a Cortex A55. This new Architecture built on ARM Cortex offers a 20% overall performance improvement, optimized across 2 performance and 6 efficiency cores. So Qualcomm is using the 4th Gen with this 6+2 configuration. So it still is an Octa-core chipset but with 2 cores dedicated for higher stability and results and 6 for better power efficiency. So, more interestingly,  what this tells us is that the next 800 series will be using the 4th Gen Kryo.

The 675 is not only filled with upgrades. For example, the 675 is constructed with an 11nm process whereas the Snapdragon 670 had a 10nm process. The GPU has been downgraded from an Adreno 615 to an Adreno 612, too. With that said, Qualcomm assured us that the Snapdragon 675 performs considerably better than the Snapdragon 670. With built-in game enhancements, for example, reduce “janks” or stutters by over 90 percent during gameplay.

The Comparison of Snapdragon(s)

So let’s look at the rest of the Snapdragon 675 and detail out how it differentiates from the 670 and the 710 chipsets. So as you can see all the 3 processors use the 6+2 setup. The performance core gets a boost with the A76 instead of the A75. When it comes to GPU the 675 lags behind and as it turns out the 710 has got the best GPU. But as per Qualcomm, they have been tweaking it for a better gaming performance. The differences which can only be pointed out when we will receive a device. It supports the LPDDR4X where the X stands for even more power efficient than the standard LPDDR4.

Now that they all showcase the same DSPs across is a good thing. With the 250L, it gets the 480fps HD Slo-Mo that will pump-up any camera. The modem is exactly the same as the rest. It’s like Qualcomm didn’t even bother making an upgrade to it. Focusing on the important part, the 675 uses Samsung’s fabrication process. So, this will be built by the looks of it exclusively on Samsung’s fabrication plans.

Qualcomm’s Worse is actually Better

So coming back to the GPU here, the 675 boasts an Adreno 612 instead of a 615 or a 616 on its brothers. Qualcomm is actually saying that they have heavily optimized the gaming performance. This does mean that the overall performance will be better as compared to the rest. Qualcomm also suggests that on a list of particular games that they tried, this performs much better. They get 90% less ‘JANKS’, whatever that means.

It might get a better user experience while gaming. Qualcomm is known to make certain tweaks for a better gaming performance and experience. The list of games does suggest that it focuses on a great diversity of games. This is actually good stuff from Qualcomm. Qualcomm also states that it works closely with both mobile game and game engine developers to improve the gaming UX on Android, though this isn’t unexpected given how they’ve collaborated with game studios such as NetMarble for Snapdragon flagship chip releases in recent years.

Gaming enhancement on snapdragon 675

Although that the 600 range continues to be very strong with support for 6 cameras, 3 on the front and 3 on the back. So everything from super-res zoom to telephoto capture to specialized Bokeh mode is now available on the 675. So there’s a bunch of things that Qualcomm has put into their processors that make them very useful. They did a great deal of work for the mid-range smartphones. Expecting really strong developments from the manufacturers now. That’s it for now.
