Exoskeleton designed at Stanford lab “personalizes assistance”

Boot-like device also increases walking speed and reduces effort.

Exoskeletons may seem experimental, but they’ve been deployed in a variety of fields, from construction and manufacturing to defense. A robotics expert from Spain even won a European Inventor Award this year for developing an adaptable robotic exoskeleton for children who use wheelchairs. The design has specifically helped children with cerebral palsy.

Up until now, the biggest efficacy barrier of exoskeletons was individualization. However, a new design from the Stanford Biomechatronics Laboratory is helping users walk — untethered — with less effort, and faster.

“This exoskeleton personalizes assistance as people walk normally through the real world,” explained lab lead Steve Collins, who is also associate professor of mechanical engineering. “And it resulted in exceptional improvements in walking speed and energy economy.”

The boot-like design uses a motor that works with calf muscles. A machine-learning-based model that’s been trained through emulators gives the user an extra push every step. With torque applied to the ankle, some calf muscle function is replaced but the device helps them push off the ground. 

The goal of this design? “Helping people move through the world as they like,” explains the press release, with the team expressing their belief that commercialization could be around the corner, primarily targeting older people.

So how was it designed? As mentioned above, individualization was a significant barrier. So the team turned to emulators set up in the lab. Researchers used students and volunteers to collect data on motion and energy expenditure.  

According to PhD student Patrick Slade, the device provides twice the energy savings of previous generations of exoskeletons, which is why walking speed is faster. Graduate student Ava Lakmazaheri helped test the device, finding it fairly natural after about 15 minutes: “Walking with the exoskeletons quite literally feels like you have an extra spring in your step. It just really makes that next step so much easier.”

Next step for researchers is to see how it can be adapted for older people, and those with disabilities who are just starting to experience a decline in mobility. 

“I believe that over the next decade we’ll see these ideas of personalizing assistance and effective portable exoskeletons help many people overcome mobility challenges or maintain their ability to live active, independent, and meaningful lives,” said Slade.

Multimodal AI promises transformative changes to health care delivery

The health-care industry is slowly adopting first-generation AI technologies, but with multimodal AI on the horizon, it’s time to get ready for what’s next

Published

Multimodal AI is the next big thing in health care. Except the previous next big thing — regular ‘garden variety’ unimodal AI — hasn’t even fully arrived yet.

“In health care, AI is a promising technology that has been deployed in very small pockets here and there, but it has not broadly impacted health care in a meaningful way,” said Dr. Amol Verma, a physician, scientist, Assistant Professor in General Internal Medicine at St. Michael’s Hospital and the University of Toronto and the 2023 Temerty Professor of AI Research and Education in Medicine at the University of Toronto. 

“The vast majority of clinicians don’t really use AI in their clinical practice.” 

That fact doesn’t mean we’re not at the outset of a multimodal AI revolution in health care, with transformative changes including diagnostics, enabling remote care, and driving efficiencies in an industry not exactly known for them.

But before we get too far ahead of ourselves here — what exactly is multimodal AI?

Multimodal AI systems are capable of processing and synthesizing multiple forms of data in order to provide outputs that include decisions, recommendations, and predictions. 

Just like people.

“We are multimodal,” said Elham Dolatabadi, a data scientist and Assistant Professor at York University focused on machine learning in health care. “We can smell, see, and hear. These are all different modalities. Our brains integrate them to come to one decision.”

So, where a unimodal AI system in health care might only be able to assess MRI scans, a multimodal AI system could process the information from that MRI scan, along with clinical notes, lab tests, genomic data and real-time patient health tracking information, amongst other inputs. In this way, a multimodal AI system would replicate the way actual doctors process patient health information — by considering and analyzing multiple sources of data.

What multimodal AI could mean for health care

Multimodal AI systems could bring almost unfathomable computational power to health care, especially when it comes to diagnostics and predictive capabilities. This could mean a much more personalized and precise approach to health care for individual patients. Think earlier, more accurate diagnoses and better outcomes — all at scale. 

For example, a computer could process radiology images and incorporate that data into its predictions to make them more accurate. It could also incorporate actual conversations between a patient and physician and even assess clinical deterioration from the sound of a patient’s voice.

Multimodal AI could also unlock the potential of telemedicine. Right now, health care providers are limited to assessments based on their conversations and observations over video calls. But if a patient had sensory technology in their home capturing their personal data and feeding it into a multimodal AI system, that could change health care dynamics for millions of patients. 

“It could dramatically improve access to care for people who are far away from clinical care or who, for whatever reason, have a hard time getting out of their house,” said Dr. Verma.

Wait times could also be improved. For example, patients regularly face wait times for ultrasound imaging. That’s partly because operating an ultrasound machine is what’s called ‘operator dependent.’ A clinician needs to be properly trained to use it. But AI could actually help patients capture their own images if it was embedded in a device they could use themselves.

“It could change who can deliver health care, not just who receives it,” said Dr. Verma.

Ethical considerations remain central to AI deployment in health care

For many, the widespread use of AI in health care still seems risky. What about privacy? What about the risks of entrusting critical patient care decisions to AI? 

Shaina Raza is an Applied Machine Learning Scientist for Responsible AI at the Vector Institute, an independent, not-for-profit focused on AI research. Her work focuses on the ethics of responsible AI in public health.

“With critical decisions about the life or death of a person, the doctors should make those decisions,” said Raza. “It’s not appropriate for generative AI models to do that. But if AI is used to facilitate research or help the doctors’ decisions, that’s different. We can save hundreds or thousands of hours that way.”

Raza notes that ethical AI in health care is ultimately about humans creating the frameworks for the AI before it’s ever fully deployed. That’s how best to address issues like patient privacy and systemic biases. 

“Patient privacy is very sensitive. We need to de-identify or mask patient data before feeding it into the AI models.” said Raza. “We can also clean the data for biases before we feed it into the models, with what we call prompt engineering, the instructions we provide to the models.”

Once these sticky issues are addressed, multimodal AI will likely have revolutionary, positive impacts on our health-care system. But since the health-care industry is typically slow to adopt new technologies, that revolution may have to wait a few years.

This might actually be a good thing, according to Dr. Verma.

“Technology is deployed much more widely in the general society than it is in medicine,” said Dr. Verma. “We’re talking about a profession that still frequently uses fax machines. I can do more sophisticated things on my mobile device than I can for applications that are medical-specific. That’s a good thing because the stakes in medicine are very high — literally life and death. We don’t want to be deploying unproven technology so rapidly in that context.”

So while multimodal AI isn’t yet ready for broad deployment, the industry is still preparing for what’s next.

“Our aim is to include as many modalities in the models as possible, including images, text, electronic medical records, wearables, signals like ECG and EEG, and genomics,” said Dolatabadi, who is currently conducting research in multimodal learning with generative AI. 

“Then the models could be used for different applications. And once the models are built, hospitals or health-care organizations can fine tune them for their own applications and patient populations.”

How health-care organizations and providers can prepare for the age of multimodal AI

With multimodal AI a matter of when and not if, it’s incumbent upon everyone in the health-care industry to be prepared for the changes ahead. 

Dr. Verma outlines four key key areas of focus over the next few years: 

  1. Design the right systems to safely deploy AI technologies. “We need to be designing the right institutions, relationships and incentives. That means creating, effectively, centres of excellence with the infrastructure, data and skilled personnel that can monitor AI technologies. These centres would then connect to primary providers, who you can’t expect to assess whether an AI solution is working. That’s just not feasible or practical for them.”
  1. Create a plan for collecting critical data to avoid exacerbating system biases. “We know systems are prone to bias, so the second thing that must happen at a system level is creating a plan to collect data about patient race, language and gender, which we currently do not collect. If we don’t collect that information, we won’t know whether solutions are biased and will therefore perform poorly. We could end up exacerbating biases in our health-care system.”
  1. Building up AI expertise, skills and organizational capacity. “Organizations need to identify AI champions, either through recruitment or upskilling. They need people that have technical skills and skills related to the legality and ethics of AI. And they need people that have skills related to the change management aspects of AI implementation. There’s also the question of scale. Not every organization can do this. Big organizations should scale up and smaller organizations that can’t should partner with big organizations that can.”
  1. Get educated on AI technologies. “I think at the individual practitioner level, people basically just need to become more aware and educated through professional development. Some basic understanding of these technologies would be good.”

Despite all the complexity with AI, there are options for more people to live longer, healthier lives if multimodal AI is deployed across the health-care system. The fact that health-care organizations are still working to embed unimodal much less multimodal AI doesn’t change the trajectory. In the coming years, almost all of us will find our health care experiences enabled by AI in ways both obvious and hidden. It’s the inevitable next step.

New IT infrastructure for Gilbane includes LLMs, payment automation, and unified tech departments

A look at 153-year old real estate titan Gilbane’s digital transformation

Published

on

Share this:

Canada’s construction industry has been slower to get on the digital transformation train. Yet virtual design and automation presents serious opportunities for the industry to evolve with digital transformation. 

Research shows that more than 80% of construction companies have room to improve their data capabilities, and the most commonly cited benefits of digital transformation were increased productivity, customer experience and staff safety.

One company that made it happen is Gilbane — a U.S.-based real estate development company worth more than $6.5 billion, with family roots that persevere to this day. In fact, they even have employees in the family’s sixth generation. Despite the “legacy” mindset in the company’s fabric (it’s 153 years old) and business industry, Gilbane boosted risk management and productivity under a brand new modular IT infrastructure. 

Here’s how they did it (and how you can, too):

Unify all digital initiatives under one leader

The company created a position that was responsible for overseeing the progress on multiple tech initiatives, including AI, analytics, IT, and cybersecurity. This helped them avoid the risk of wasted budgets through silos and miscommunication. 

“We believe this structure is the most effective to bring together our data and technology resources to drive transformation and get a real return on invested capital.”Karen Higgins-Carter, Chief Digital Information Officer (CDIO)

Invest in analytics and AI for risk management

Safety is a primary concern in the construction industry. Despite improvements in safety measures, equipment, and training, the construction industry still experiences high rates of death and injury. In fact, in 2022 the National Safety Council ranked the construction industry in the top four most dangerous, noting that it experienced the most workplace deaths.

Gilbane’s team is investing in analytics and AI with large language mode experiments to help them identify similar trends that indicate potential unsafe characteristics on a worksite, Higgins-Carter told CIO. “In construction, our teams are managing the construction of hundreds of projects happening at any one time,” she said. “Our analytics capabilities identify potentially unsafe conditions so we can manage projects more safely and mitigate risks.”

“To help us manage risk, I need to understand the leading indicators of risk on a job, like attrition or high volumes of change order.”Karen Higgins-Carter, Chief Digital Information Officer (CDIO)

Automate payment processing with operation-specific triggers

Higgins-Carter told CIO the company recently piloted an automated payment program for Gilbane to pay subcontractors more efficiently. Powered by videos and photos of work completed as triggers, payments are automatically dispensed to the necessary parties. 

Educate the entire team and inform new processes with their experience

Hold meetings and training sessions to ensure executives and employees  understand the benefits and functions of any new tech or business processes. 

“We can’t deliver technology if we don’t understand our employees’ experience. If I go out to a job site once a month, then my team will too.”Karen Higgins-Carter, Chief Digital Information Officer (CDIO)

The Northern Lights Technology & Innovation Forum navigates AI, economic concerns and upskilling in Alberta

Panelists dive into how innovation and collaboration may help navigate the changing industry landscapes

Published

Share this:

While rapid advancements in AI are reshaping industries worldwide, they’ve sparked discussions about innovation and community resilience through ongoing economic challenges. At this year’s Northern Lights Technology and Innovation Forum, panelists explored how technology could drive positive adaptation.

​​Moderated by the Calgary Economic Development’s Geraldine Anderson, the panel featured:

  • Mark Little, co-founder and CEO Jotson Inc, and board member of General Fusion
  • Anna Baird, culture and innovation evangelist at Google
  • Dan Semmens, SVP and head of data and IT at ATB Financial
  • Arthur Kent, Canadian journalist and author
  • Joy Romero, executive advisor innovation at Canadian Natural Resources Limited (CNRL)

Approximately 250 attendees gathered for the forum at the Calgary Petroleum Club on Feb. 8. Filled with industry leaders and burgeoning entrepreneurs, the forum focused on collaboration and knowledge sharing in the tech sector.

Over the past five years, Calgary has seen a 22 per cent increase in tech talent and total tech jobs, emerging as one of North America’s top markets for young tech professionals.

“The talent pool here is amazing,” said ​​John Givens, vice president of sales at C3 AI and one of the event’s organizers. “So how do we leverage our talent here? How do we share that knowledge?”

In response, this year’s forum included the inaugural “Mentors and Makers” initiative, where a dozen industry experts pinned green buttons to their lapels, signaling to anyone in the crowd that they’re open to a conversation.

Shawn Mahoney, another event organizer and co-founder of Spare Parts & Gasoline, said in his opening remarks that the initiative speaks to “creating the new innovators that we need to solve tomorrow’s problems.”

And with that, the panel took the stage to dig into the big questions: What are the challenges and opportunities for Alberta as a growing tech market? How will AI continue to change industries across the board? And if it does, will that be a bad thing?

The Alberta advantage

The panel conversation was kicked off by the first question asked by moderator Geraldine Anderson: “What is the Alberta mindset, or the ‘Alberta advantage?’”

Mark Little, co-founder and CEO Jotson Inc, said Alberta has a lot going for it — including having the highest GDP in Canada, a younger population, and high education levels — but those aren’t the advantages that stand out to him.

“There’s a resilience and an entrepreneurial spirit here,” he said. “As a result of that, we’re seeing innovation … I think 10 to 15 years from now we’re going to lead this country in innovation and it’ll be every sector you could imagine.”

Hailing from Vancouver and the only panelist not based in Calgary, Google’s Anna Baird said she considers herself an honorary Albertan based on the “sheer grittiness and roll up your sleeves and work together” attitude she’s witnessed. 

“The grittiness takes us into innovation,” said Baird. “We’re willing to try new things, we’re willing to fail — hopefully fast and cheaply, as is Google’s ethos. But we’re also willing to borrow with pride and give kudos to the people we’re borrowing the pride from so we can have building blocks.” 

The panelists’ discussion kept coming back to the importance of adaptability, innovation, and collaboration. While the province faces significant hurdles, including global market fluctuations and environmental concerns, they spoke with optimism about the potential to emerge stronger by investing in the future.

Dan Semmens, SVP and head of data and IT at ATB Financial, calls it an “opportunity” for both the province and country to focus on investing in the next generation.

“I think the opportunity there is continuing to invest in our most precious resource, which is our young people,” he said. 

When it comes to AI, “it’s on all of us” to level up our own skills

AI is already impacting most industries globally, and it shows no signs of slowing down. But it’s not new either.

Joy Romero, executive advisor of innovation at Canadian Natural Resources Limited (CNRL), said she was using AI neural networks 20 years ago to take ecological data and process it through oil sands facilities. 

“Why?” she asked. “Because that would allow us to improve our processing and our productivity … So for me, digital is our world. That’s productivity.”

The day of the panel, Google announced that Gemini Ultra 1.0, the largest version of their large language model, is being released to the public. 

Baird was asked about the implications of the new AI model, and while she acknowledged there will be challenges, she maintained that “the train has left the station.”

“It’s on all of us here in the room to level up our own skills,” she says. “With an announcement like Gemini, like you have to get in there, you have to play, you have to try.”

Transitioning to the realm of media and journalism, Canadian journalist Arthur Kent highlighted the increasing role of AI in newsrooms. From assisting journalists in gathering and analyzing data to content creation, journalists are experimenting with AI for efficiency and detecting false information.

“We can become even better if we harness artificial intelligence to do that,” said Kent. “So we constantly have to be developing and pushing ourselves forward, to keep pace with this.”

However, he emphasized the critical role of journalists in maintaining integrity and discerning between fact and fiction in an era of AI-generated content. 

“Journalism is always going to be a human process, because journalism is based on their location, and verification, verifying leads, tips, and figuring out rumour from fact,” said Kent. “So far, none of the machines that I’ve seen associated with artificial intelligence, have those human characteristics. However, there is also that human aspect called temptation.”

In the financial services industry, Semmens said the impact of generative AI “poses an existential risk” to the relationship banks have with their clients. 

Despite this, he says incorporating AI technology into banking is “an incredible opportunity” to personalize experiences for customers more effectively and efficiently, and he expects to see a lot of changes in open banking in the next three to five years. 

“With all the disinformation that is out there, a trusted source is going to be a high commodity,” he said. “And so I think in banking, being a heavily regulated industry, there is an opportunity for us to really show up from that standpoint.”

An innovation forum’s charitable roots

The Northern Lights Technology and Innovation Forum’s story begins over a decade ago. The organizers, including Givens, first banded together for the Gordie Howe C.A.R.E.S. Hockey Pro-Am Tournament in support of Alzheimer’s research and education. 

As the cause drew more attention they opted to expand the tournament into the forum as a way to expand their reach. All of the event proceeds go to Gordie Howe C.A.R.E.S. Centre for the Alzheimer’s Research and Education Society — and this year they broke their record, raising a minimum of $40,000 thanks in part to a funding match made by Google. 

“It’s amazing,” Givens said at the end of the night. “I always knew the potential of our community. And I explained to people that the community is the draw … It’s about education. It’s about doing the right thing. It’s about just finding ways for other people to get involved in doing the same thing. There’s enough energy there. Now we just have to harness it.”
