At democracy’s heart lies a set of paradoxes: a delicate interplay of identity and anonymity, secrecy and transparency. To be sure you are eligible to vote and that you do so only once, the authorities need to know who you are. But when it comes time for you to mark a ballot, the government must guarantee your privacy and anonymity. After the fact, it also needs to provide some means for a third party to audit the election, while also preventing you from obtaining definitive proof of your choice, which could lead to vote selling or coercion.
Building a system that accomplishes all this at once — and does so securely — is challenging enough in the physical world. It’s even harder online, as the recent revelation that Russian intelligence operatives compromised voting systems in multiple states makes clear.
In the decade since the elusive Satoshi Nakamoto published an infamous white paper outlining the idea behind bitcoin, a “peer-to-peer electronic cash system” based on a mathematical “consensus mechanism,” more than 1,500 new cryptocurrencies have come into being.
definition: Nathan Heller in the New Yorker, in which he compares the blockchain to a scarf knit with a single ball of yarn. “It’s impossible to remove part of the fabric, or to substitute a swatch, without leaving some trace,” Heller wrote. Typically, blockchains are created by a set of stakeholders working to achieve consensus at every step, so it might be even more apt to picture a knitting collective creating that single scarf together, moving forward only when a majority agrees that a given knot is acceptable.
Unlike bitcoin, a public blockchain powered by thousands of miners around the world, most voting systems, including Votem’s, employ what’s known as a “permissioned ledger,” in which a handful of approved groups (political parties, election observers, government entities) would be allowed to validate the transactions.
there’s the issue of targeted denial-of-service (DoS) attacks, in which a hacker directs so much traffic at a server that it’s overwhelmed and ceases to function.
Although a distributed ledger itself would likely withstand such an attack, the rest of the system — from voters’ personal devices to the many servers a vote would pass through on its way to the blockchain — would remain vulnerable.
there’s the so-called penetration attack, like the University of Michigan incursion, in which an adversary gains control of a server and deliberately alters the outcome of an election.
While it’s true that information recorded on a blockchain cannot be changed, a determined hacker might well find another way to disrupt the process. Bitcoin itself has never been hacked, for instance, but numerous bitcoin “wallets” have been, resulting in billions of dollars in losses. In early June 2018, a South Korean cryptocurrency exchange was penetrated, causing the value of bitcoin to tumble and resulting in a loss of $42 billion in market value. So although recording the vote tally on a blockchain introduces a new obstacle to penetration attacks, it still leaves holes elsewhere in the system — like putting a new lock on your front door but leaving your basement windows open.
A blockchain is only as valuable as the data stored on it. And whereas traditional paper ballots preserve an indelible record of the actual intent of each voter, digital votes “don’t produce an original hard-copy record of any kind,”
In the end, democracy always depends on a certain leap of faith, and faith can never be reduced to a mathematical formula. The Economist Intelligence Unit regularly ranks the world’s most democratic counties. In 2017, the United States came in 21st place, after Uruguay and Malta. Meanwhile, it’s now widely believed that John F. Kennedy owed his 1960 win to election tampering in Chicago. The Supreme Court decision granting the presidency to George W. Bush rather than calling a do-over — despite Al Gore’s popular-vote win — still seems iffy. Significant doubts remain about the 2016 presidential race.
While little doubt remains that Russia favored Trump in the 2016 election, the Kremlin’s primary target appears to have been our trust in the system itself. So if the blockchain’s trendy allure can bolster trust in American democracy, maybe that’s a net positive for our national security. If someone manages to hack the system, hopefully they’ll do so quietly. Apologies to George Orwell, but sometimes ignorance really is strength.
when exchanging digital goods, how do you know somebody hasn’t sent the same asset to two people simultaneously?
use a ledger (a record of transactions) to track our trade.put our trust in this third party.we gave a copy of the ledger to every pokemon trader
if I had duplicated my card, sent one copy out earlier then tried to send the second one to you, the history of that trade would already exist, so my second trade to you would conflict and be rejected.
that digital signature that gets put on each block? That is actually generated based on the info in the block, so changing the data (i.e removing my trade) automatically changes the signature.
an open, decentralised, non-reversible, tamper-proof digital network for trading valuable assets.
This is a simplified version of how blockchain technology works, but it’s easy to see how this tech gives Bitcoin its unique and fascinating properties.
p. 5 a LibGuide was created that provided a better description of the available software for both the Microsoft Hololens and the HTC Vive and also discussed potential applications for the technology.
Both the HTC Vive and the Hololens were made bookable through the library’s LibCalendar booking system, streamlining the booking process and creating a better user experience.
When the decision was made to bring virtual and augmented reality into the McGill University Library, an important aspect of this project was to develop a collection of related software to be used alongside the technology. In building this software collection a priority was placed on acquiring software that could be demonstrated as having educational value, or that could potentially be used in relation to, or in support of, university courses.
For the Microsoft Hololens, all software was acquired through Microsoft’s Online Store. The store has a number of educationally relevant HoloLens apps available for purchase. The app ARchitect, for example, gives a basic sense of how augmented reality could be used for viewing new building designs. The app Robotics BIW allows user to simulate robotic functions. A select number of apps, such as Land of the Dinosaurs and Boulevard, provide applications for natural history and art. There were a select number of apps related to science, mathematics and medicine, and others with artistic applications. All of the HoloLens applications were free but, compared to what is available for virtual reality, the experiences were much smaller in size and scope.
For the HoloLens, a generic user account was created and shared with person who booked the HoloLens at the time of their booking. After logging into this account – which could sometimes prove to be a challenge because typing is done using the headset’s gesture controls – the user could select a floating tile which would reveal a list of available software. An unresolved problem was that users would then need to refer to the HoloLens LibGuide for a detailed description of the software, or else choose software based on name alone, and the names were not always helpful.
For the Microsoft HoloLens, the three most popular software programs were Land of the Dinosaurs, Palmyra and Insight Heart. Insight Heart allow users to view and manipulate a 3D rendering of a high-resolution human heart, Land of the Dinosaurs provided an augment reality experience featuring 3D renderings of dinosaurs, and Palmyra gave an augmented reality tour of the ancient city of Palmyra.
p. 7 Though many students had ideas for research projects that could make use of the technology, there was no available software that would have allowed them to use augmented reality in the way they wanted. There were no students interested in developing their own software to be used with the technology either.
p. 8 we found that the Microsoft HoloLens received significant use from our patrons, we would recommend the purchase of one only for libraries serving researchers and developers.

Getting Real in the Library: A Case Study at the University of Florida
As an alternative, Microsoft offers a Hololens with enterprise options geared toward multiple users for $5000.
The transition from mobile app development to VR/AR technology also reflected the increased investment in VR/AR by some of the largest technology companies in the world. In the past four years, Facebook purchased the virtual reality company Oculus, Apple released the ARKit for developing augmented reality applications on iOS devices, Google developed Google Cardboard as an affordable VR option, and Sony released Playstation VR to accompany their gaming platform, just to name a few notable examples. This increase of VR/AR development was mirrored by a rise in student interest and faculty research in using and creating new VR/AR content at UF.

‘HoloMuse’ that engage users with archaeological artefacts through gesture-based interactions (Pollalis, Fahnbulleh, Tynes, & Shaer, 2017). Another research utilised HoloLens to provide in-situ assistant for users (Blattgerste, Strenge, Renner, Pfeiffer, & Essig, 2017). HoloLens also used to provide magnification for low vision users by complementary finger-worn camera alongside with the HMD (Stearns, DeSouza, Yin, Findlater, & Froehlich, 2017). Even in the medical applications, HoloLens contributed in 3D visualisation purposes using AR techniques (Syed, Zakaria, & Lozanoff, 2017) and provide optimised measurements in medical surgeries(Pratt et al., 2018) (Adabi et al., 2017). Application of HoloLens extended to visualise prototype designs (DeLaOsa, 2017) and showed its potential in gaming industry (Volpe, 2015) (Alvarez, 2015) and engaging cultural visitors with gaming activities (Raptis, Fidas, & Avouris, 2017).

Evaluating the Microsoft HoloLens through an augmented reality assembly application
To assess the HoloLens’ potential for delivering AR assembly instructions, the cross-platform Unity 3D game engine was used to build a proof of concept application. Features focused upon when building the prototype were: user interfaces, dynamic 3D assembly instructions, and spatially registered content placement. The research showed that while the HoloLens is a promising system, there are still areas that require improvement, such as tracking accuracy, before the device is ready for deployment in a factory assembly setting.

We use Microsoft HoloLens device to augment the user’s experience in the real library and to provide a rich set of affordances for embodied and social interactions.We describe a mixed reality based system, a prototype mixed library, that provides a variety of affordances to support embodied interactions and improve the user experience.
Computer science as an engineering discipline has been spectacularly successful. Yet it is also a philosophical enterprise in the way it represents the world and creates and manipulates models of reality, people, and action. In this book, Paul Dourish addresses the philosophical bases of human-computer interaction. He looks at how what he calls “embodied interaction”—an approach to interacting with software systems that emphasizes skilled, engaged practice rather than disembodied rationality—reflects the phenomenological approaches of Martin Heidegger, Ludwig Wittgenstein, and other twentieth-century philosophers. The phenomenological tradition emphasizes the primacy of natural practice over abstract cognition in everyday activity. Dourish shows how this perspective can shed light on the foundational underpinnings of current research on embodied interaction. He looks in particular at how tangible and social approaches to interaction are related, how they can be used to analyze and understand embodied interaction, and how they could affect the design of future interactive systems.

HoloMuse, an AR application for the HoloLens wearable device, which allows users to actively engage with archaeological artifacts from a museum collection
pick up, rotate, scale, and alter a hologram of an original archeological artifact using in-air gestures. Users can also curate their own exhibit or customize an existing one by selecting artifacts from a virtual gallery and placing them within the physical world so that they are viewable only using the device. We intend to study the impact of HoloMuse on learning and engagement with college-level art history and archeology students.
