FACTT (Festival of Art and Science) 2021: Improbable Times on Thursday, Jan.28.21 at 3:30 pm EST

Courtesy: Arte Institute

Plans for last year’s FACTT (Festival of Art and Science) 2020 had to be revised at the last minute due to COVID-19. This year, organizers were prepared so no in person sessions have to be cancelled or turned into virtual events. Here’s more from the Jan. 25, 2021 announcement I received (via email) from one of the festival partners, the ArtSci Salon at the University of Toronto,

Join us! Opening of FACTT 20-21 Improbable Times! 

Thursday, January 28, 2021 at 3:30 PM EST – 5:30 PM EST
Public  · Anyone on or off Facebook – link will be disseminated closer to the event.

The Arte Institute and the RHI Initiative, in partnership with Cultivamos Cultura, have the pleasure to present the FACTT 2021 – Festival Art & Science. The festival opens on January 28, at 8.30 PM (GMT), and will be exhibited online on RHI Stage.

This year we are reshaping FACTT! Come join us for the kick-off of this amazing project!

A project spearheaded and promoted by the Arte Institute we are in or production and conception partners with Cultivamos Cultura and Ectopia (Portugal), InArts Lab@Ionian University (Greece), ArtSci Salon@The Fields Institute and Sensorium@York University (Canada), School of Visual Arts (USA), UNAM, Arte+Ciência and Bioscenica (Mexico), and Central Academy of Fine Arts (China).

Together we will work and bring into being our ideas and actions for this during the year of 2021!

FACTT 20/21 – Improbable Times presents a series of exceptional artworks jointly curated by Cultivamos Cultura and our partners. The challenge of a translation from the physical space that artworks occupy typically, into an exhibition that lives as a hybrid experience, involves rethinking the materiality of the work itself. It also questions whether we can live and interact with each other remotely and in person producing creative effective collaborative outcomes to immerse ourselves in. Improbable Times brings together a collection of works that reflect the times we live in, the constraints we are faced with, the drive to rethink what tomorrow may bring us, navigate it and build a better future, beyond borders.

January 28, 2021 | 8:30 PM (GMT)Program:
– Introduction
– Performance Toronto: void * ambience : Latency, with Joel Ong, Michael Palumbo and Kavi
– Performance Mexico “El Tercero Cuerpo Sonoro” (Third Sonorous Body), by Arte+Ciência.
– Q&A

The performance series void * ambience experiments with sound and video
content that is developed through a focus on the topographies and networks through which these flow. Initiated during the time of COVID and social distancing, this project explores processes of information sharing, real-time performance and network communication protocols that contribute to the sustenance of our digital communities, shared experiences and telematic intimacies.

“El Tercero Cuerpo Sonoro” project is a digital drift that explores different relationships with the environment, nature, humans and non-humans from the formulation of an intersubjective body. Its main search is to generate resonances with and among the others.

In these complicated times in which it seems that our existence unfolds in front of the screen, confined to the space of the black mirror, it becomes urgent to challenge the limits and scopes of digital life. We need to rethink the way in which we inhabit the others as well as our own subjectivity.

IEither the RHI FACTT 2021 event page or the Arte Institute FACTT 2021 event page, offer a more detailed and, somewhat, more accessible description,

Program:
– Introduction
– Performance Toronto: Proximal Spaces
Artistic Directors: Joel Ong, Elaine Whittaker

AR [augmented reality] development : Sachin Khargie, Ryan Martin
Bioartists: Roberta Buiani, Nathalie Dubois Calero, Sarah Choukah, Nicole Clouston, Jess Holtz, Mick Lorusso, Maro Pebo, Felipe Shibuya
– Performance Mexico Tercero Cuerpo Sonoro (Third Sonorous Body) by Arte+Ciência

FACTT team: Marta de Menezes, Suzanne Anker, Maria Antonia Gonzalez Valerio, Roberta Buiani, Jo Wei, Dalila Honorato, Joel Ong, Lena Lee and Minerva Ortiz.

For FACTT20/21 we propose to put together an exhibition where the virtual and the physical share space, a space that is hybrid from its conception, a space that desires to break the limits of access to culture, to collaboration, to the experience of art. A place where we can think deeply and creatively together about the adaptive moves we had and have to develop to the rapid and sudden changes our lives and environment are going through.

Enjoy!

Smartphone as augmented reality system with software from Brown University

You need to see this,

Amazing, eh? The researchers are scheduled to present this work sometime this week at the ACM Symposium on User Interface Software and Technology (UIST) being held in New Orleans, US, from October 20-23, 2019.

Here’s more about ‘Portal-ble’ in an October 16, 2019 news item on ScienceDaily,

A new software system developed by Brown University [US] researchers turns cell phones into augmented reality portals, enabling users to place virtual building blocks, furniture and other objects into real-world backdrops, and use their hands to manipulate those objects as if they were really there.

The developers hope the new system, called Portal-ble, could be a tool for artists, designers, game developers and others to experiment with augmented reality (AR). The team will present the work later this month at the ACM Symposium on User Interface Software and Technology (UIST 2019) in New Orleans. The source code for Andriod is freely available for download on the researchers’ website, and iPhone code will follow soon.

“AR is going to be a great new mode of interaction,” said Jeff Huang, an assistant professor of computer science at Brown who developed the system with his students. “We wanted to make something that made AR portable so that people could use anywhere without any bulky headsets. We also wanted people to be able to interact with the virtual world in a natural way using their hands.”

An October 16, 2019 Brown University news release (also on EurekAlert), which originated the news item, provides more detail,

Huang said the idea for Portal-ble’s “hands-on” interaction grew out of some frustration with AR apps like Pokemon GO. AR apps use smartphones to place virtual objects (like Pokemon characters) into real-world scenes, but interacting with those objects requires users to swipe on the screen.

“Swiping just wasn’t a satisfying way of interacting,” Huang said. “In the real world, we interact with objects with our hands. We turn doorknobs, pick things up and throw things. So we thought manipulating virtual objects by hand would be much more powerful than swiping. That’s what’s different about Portal-ble.”

The platform makes use of a small infrared sensor mounted on the back of a phone. The sensor tracks the position of people’s hands in relation to virtual objects, enabling users to pick objects up, turn them, stack them or drop them. It also lets people use their hands to virtually “paint” onto real-world backdrops. As a demonstration, Huang and his students used the system to paint a virtual garden into a green space on Brown’s College Hill campus.

Huang says the main technical contribution of the work was developing the right accommodations and feedback tools to enable people to interact intuitively with virtual objects.

“It turns out that picking up a virtual object is really hard if you try to apply real-world physics,” Huang said. “People try to grab in the wrong place, or they put their fingers through the objects. So we had to observe how people tried to interact with these objects and then make our system able accommodate those tendencies.”

To do that, Huang enlisted students in a class he was teaching to come up with tasks they might want to do in the AR world — stacking a set of blocks, for example. The students then asked other people to try performing those tasks using Portal-ble, while recording what people were able to do and what they couldn’t. They could then adjust the system’s physics and user interface to make interactions more successful.

“It’s a little like what happens when people draw lines in Photoshop,” Huang said. “The lines people draw are never perfect, but the program can smooth them out and make them perfectly straight. Those were the kinds of accommodations we were trying to make with these virtual objects.”

The team also added sensory feedback — visual highlights on objects and phone vibrations — to make interactions easier. Huang said he was somewhat surprised that phone vibrations helped users to interact. Users feel the vibrations in the hand they’re using to hold the phone, not in the hand that’s actually grabbing for the virtual object. Still, Huang said, vibration feedback still helped users to more successfully interact with objects.

In follow-up studies, users reported that the accommodations and feedback used by the system made tasks significantly easier, less time-consuming and more satisfying.

Huang and his students plan to continue working with Portal-ble — expanding its object library, refining interactions and developing new activities. They also hope to streamline the system to make it run entirely on a phone. Currently the infrared sensor requires an infrared sensor and external compute stick for extra processing power.

Huang hopes people will download the freely available source code and try it for themselves. 
“We really just want to put this out there and see what people do with it,” he said. “The code is on our website for people to download, edit and build off of. It will be interesting to see what people do with it.

Co-authors on the research paper were Jing Qian, Jiaju Ma, Xiangyu Li, Benjamin Attal, Haoming Lai, James Tompkin and John Hughes. The work was supported by the National Science Foundation (IIS-1552663) and by a gift from Pixar.

Brown University, Providence RI, USA; Southeast University, Nanjing, China. Presented at ACM Symposium on User Interface Software and Technology (UIST) being held in New Orleans, US

This is the first time I’ve seen an augmented reality system that seems accessible, i.e., affordable. You can find out more on the Portal-ble ‘resource’ page where you’ll also find a link to the source code repository. The researchers, as noted in the news release, have an Android version available now with an iPhone version to be released in the future.

Improving Innovation Through Better Management

The Council of Canadian Academies released their ‘Improving Innovation Through Better Management‘ report on October 18, 2018..As some of my regular readers (assuming there are some) might have predicted, I have issues.

There’s a distinct disconnection between the described problem and the questions to be answered. From the ‘Improving Innovation Through Better Management‘ summary webpage,

While research is world-class and technology start-ups are thriving, few companies grow and mature in Canada. This cycle — invent and sell, invent and sell — allows other countries to capture much of the economic and social benefits of Canadian-invented products, processes, marketing methods, and business models. …

So, the problem is ‘invent and sell’. Leaving aside the questionable conclusion that other countries are reaping the benefits of Canadian innovation (I’ll get back to that shortly), what questions could you ask about how to break the ‘invent and sell, invent and sell’ cycle? Hmm, maybe we should ask, How do we break the ‘invent and sell’ cycle in Canada?

The government presented two questions to deal with the problem and no, how to break the cycle is not one of the questions. From the ‘Improving Innovation Through Better Management‘ summary webpage,

… Escaping this cycle may be aided through education and training of innovation managers who can systematically manage ideas for commercial success and motivate others to reimagine innovation in Canada.

To understand how to better support innovation management in Canada, Innovation, Science and Economic Development Canada (ISED) asked the CCA two critical questions: What are the key skills required to manage innovation? And, what are the leading practices for teaching these skills in business schools, other academic departments, colleges/polytechnics, and industry?

As lawyers, journalists, scientists, doctors, librarians, and anyone who’s ever received misinformation can tell you, asking the right questions can make a big difference.

As for the conclusion that other countries are reaping the benefits of Canadian innovation, is there any supporting data? We enjoy a very high standard of living and have done so for at least a couple of generations. The Organization for Economic Cooperation and Development (OECD) has a Better Life Index, which ranks well-being on these 11 dimensions (from the OECD Better Life Index entry on Wikipedia), Note: Links have been removed,

  1. Housing: housing conditions and spendings (e.g. real estate pricing)
  2. Income: household income and financial wealth
  3. Jobs: earnings, job security and unemployment
  4. Community: quality of social support network
  5. Education: education and what you get out of it
  6. Environment: quality of environment (e.g. environmental health)
  7. Governance: involvement in democracy
  8. Health
  9. Life Satisfaction: level of happiness
  10. Safety: murder and assault rates
  11. Work-life balance

In 2017, the index ranked Canada as fifth in the world while the US appears to have slipped from a previous ranking of 7th to 8th. (See these Wikipedia entries with relevant subsections for rankings:  OECD Better Life Index; Rankings, 2017 ranking and Standard of living in the United States, Measures, 3rd paragraph.)

This notion that other countries are profiting from Canadian innovation while we lag behind has been repeated so often that it’s become an article of faith and I never questioned it until someone else challenged me. This article of faith is repeated internationally and sometimes seems that every country in the world is worried that someone else will benefit from their national innovation.

Getting back to the Canadian situation, we’ve decided to approach the problem by not asking questions about our article of faith or how to break the ‘invent and sell’ cycle. Instead of questioning an assumption and producing an open-ended question, we have these questions (1) What are the key skills required to manage innovation? (2) And, what are the leading practices for teaching these skills in business schools, other academic departments, colleges/polytechnics, and industry?

in my world that first question, would be a second tier question, at best. The second question, presupposes the answer: more training in universities and colleges. I took a look at the report’s Expert Panel webpage and found it populated by five individuals who are either academics or have strong ties to academe. They did have a workshop and the list of participants does include people who run businesses, from the Improving Innovation Through Better Management‘ report (Note: Formatting has not been preserved),

I am a little puzzled by the IBM executive’s presence (Dan Sinai) on this list. Wouldn’t Canadians holding onto their companies be counterproductive to IBM’s interests? As for John L. Mann, I’ve not been able to find him or his consulting company online. it’s unusual not to find any trace of an individual or company online these days.

In all there were nine individuals representing academic or government institutions in this list. The gender balance is 10 males and five females for the workshop participants and three males and two females for the expert panel. There is no representation from the North or from Manitoba, Saskatchewan, Prince Edward Island, or Newfoundland.

If they’re serious about looking at how to use innovation to drive higher standards of living, why aren’t there any people from Asian countries where they have been succeeding at that very project? South Korea and China come to mind.

I’m sure there are some excellent ideas in the report, I just wish they’d taken their topic to heart and actually tried to approach innovation in Canada in an innovative fashion.

Meanwhile, Vancouver gets another technology hub, from an October 30, 2018 article by Kenneth Chan for the Daily Hive (Vancouver [Canada]), Note: Links have been removed,

Vancouver’s rapidly growing virtual reality (VR) and augmented reality (AR) tech sectors will greatly benefit from a new VR and AR hub created by Launch Academy.

The technology incubator has opened a VR and AR hub at its existing office at 300-128 West Hastings Street in downtown, in partnership with VR/AR Association Vancouver. Immersive tech companies have access to desk space, mentorship programs, VR/AR equipment rentals, investor relations connected to Silicon Valley [emphasis mine], advisory services, and community events and workshops.

Within the Vancouver tech industry, the immersive sector has grown from 15 companies working in VR and AR in 2015 to 220 organizations today.

Globally, the VR and AR market is expected to hit a value of $108 billion by 2021, with tech giants like Amazon, Apple, Facebook, Google, and Microsoft [emphasis mine] investing billions into product development.

In the Vancouver region, the ‘invent and sell’ cycle can be traced back to the 19th century.

One more thing, as I was writing this piece I tripped across this news: “$7.7-billion pact makes Encana more American than Canadian‘ by Geoffrey Morgan. It’s in the Nov. 2, 2018 print edition of the Vancouver Sun’s front page for business. “Encana Corp., the storied Canadian company that had been slowly transitioning away from Canada and natural gas over the past few years under CEO [Chief Executive Officer] Doug Suttles, has pivoted aggressively to US shale basins. … Suttles, formerly as BP Plc. executive, moved from Calgary [Alberta, Canada] to Denver [Colorado, US], though the company said that was for personal reasons and not a precursor to relocation of Encana’s headquarters.”  Yes, that’s quite believable. By the way, Suttles has spent* most of his life in the US (Wikipedia entry).

In any event, it’s not just Canadian emerging technology companies that get sold or somehow shifted out of Canada.

So, should we break the cycle and, if so, how are we going to do it?

Improving silver nanowires for flexible transparent conducting electrodes (FTCEs)

This is a very pretty image from the Korea Advanced Institute of Science and Technology (KAIST),

Picture 1: Artistic Rendtition of Light Interaction with Nanomaterials (This image shows flash-induced plasmonic interactions with nanowires to improve silver nanowires (Ag NWs).) Courtesy: KAIST

An April 4, 2017 news item on plys.org announces the research,

Flexible transparent conducting electrodes (FTCEs) are an essential element of flexible optoelectronics for next-generation wearable displays, augmented reality (AR), and the Internet of Things (IoTs). Silver nanowires (Ag NWs) have received a great deal of attention as future FTCEs due to their great flexibility, material stability, and large-scale productivity. Despite these advantages, Ag NWs have drawbacks such as high wire-to-wire contact resistance and poor adhesion to substrates, resulting in severe power consumption and the delamination of FTCEs.

A Korean research team led by Professor Keon Jae Lee of the Materials Science and Engineering Department at KAIST and Dr. Hong-Jin Park from BSP Inc., has developed high-performance Ag NWs (sheet resistance ~ 5 Ω /sq, transmittance 90 % at λ = 550 nm) with strong adhesion on plastic (interfacial energy of 30.7 J m-2) using flash light-material interactions.

An April 5, 2017 KAIST press release (also on EurekAlert), which originated the news item, explains more about the research,

The broad ultraviolet (UV) spectrum of a flash light enables the localized heating at the junctions of nanowires (NWs), which results in the fast and complete welding of Ag NWs. Consequently, the Ag NWs demonstrate six times higher conductivity than that of the pristine NWs. In addition, the near-infrared (NIR) of the flash lamp melted the interface between the Ag NWs and a polyethylene terephthalate (PET) substrate, dramatically enhancing the adhesion force of the Ag NWs to the PET by 310 %.

Professor Lee said, “Light interaction with nanomaterials is an important field for future flexible electronics since it can overcome thermal limit of plastics, and we are currently expanding our research into light-inorganic interactions.”

Meanwhile, BSP Inc., a laser manufacturing company and a collaborator of this work, has launched new flash lamp equipment for flexible applications based on the Prof. Lee’s research.

The results of this work entitled “Flash-Induced Self-Limited Plasmonic Welding of Ag NW Network for Transparent Flexible Energy Harvester (DOI: 10.1002/adma.201603473)”(http://onlinelibrary.wiley.com/doi/10.1002/adma.201603473/pdf) were published in the February 2, 2017 issue of Advanced Materials as the cover article.

Professor Lee also contributed an invited review in the same journal of the April 3 2017 online issue, “Laser-Material Interaction for Flexible Applications,” overviewing the recent advances in light interactions with flexible nanomaterials.

Lately, It seems I’ve stumbled across quite a few stories about wearable technologies and research to improve them.
