Robots Are Paving the Way of Our Aging Future

From a seal that can soothe and engage the elderly, to a talking boy who can help assess dementia patients, robots already have a place in the world of elder care, and that role is only expected to grow as technology advances and the population ages.


It is a prospect that worries some, who fear robots will be used to reduce human care and contact, especially with the elderly in institutions.


Researchers at the world’s largest gathering of aging experts meeting in San Francisco this week said there is evidence that some robots can enhance social contact, rather than isolating elderly patients.


Following are some examples to date. For photos of then and a video, visit the Ottawa Citizen website and scroll down.


Paro, the Japanese-developed robotic seal used to soothe and engage dementia patients, is one of the best known, but there are others:


Ludwig, a boy robot being tested at a Toronto long-term care home. Developed by Dr. Frank Rudzicz, an assistant professor of computer science at the University of Toronto, it has back-and-forth conversations with dementia patients, asks patients to describe pictures on a screen and assesses them.


Japan, with the world’s oldest population, also leads the world in the development of robots for the elderly. One estimate put the global personal care robot market at more than $17 billion by 2020.


Among so-called carebots are:


Asimo, designed by Honda, which could help the elderly by getting them food and turning off lights. (See photo.)


Robear, an experimental nursing robot designed to pick patients up and transfer them from bed to wheelchair, for example. There are also smaller companion robots meant to replace pets.


Other robots in the works and on the market include Buddy, billed as a companion robot on wheels that can monitor your home, connect to smart devices, act as a personal assistant and provide social interaction.


Nao, created by French developers, is an “autonomous, programmable humanoid robot developed by Paris-based Aldebaran Robotics.


Elizabeth Broadbent, associate professor of health psychology at the University of Auckland in New Zealand, says designers study humans “in great detail” in order to build robots that are socially acceptable.


When they succeed, there is often a human robot connection.


“People enjoy talking to robots even when they know robots can’t understand what they are saying,” she said.

Takanori Shibata, but its voice is made in Canada. Shibata recorded the baby harp seal, which became the voice of Paro, on Quebec’s Magdalen Islands.


“It’s a Canadian seal,” said Shibata, who showed off his cuddly creation at the world’s largest gathering of experts in the field of aging this week in San Francisco.


Paro, now used to help dementia patients and others in 30 countries around the world, is a huggable face of the high-tech future of aging. The burgeoning field is known as gerontechnology.


Eases Stress for Dementia Patients                         


Paro, which has been used in Japan and through Europe since 2003, has helped demonstrate that technology can be used and embraced in previously-unheard-of ways for eldercare. The robot seal, which responds to touch and makes eye contact, has been found to reduce patient and caregiver stress, to stimulate interaction between patients and caregivers and to improve the socialization of patients. It has also been found to reduce the need for medication in some cases.


It’s not all as warm and fuzzy as Paro, but technology — from smart homes, to health monitoring devices, to virtual reality therapy, to autonomous transportation, to technological advancements not yet dreamed of — are all part of the future of aging, according to experts.


Held in San Francisco, the World Congress of Gerontology and Geriatrics, devoted an entire day this week to technology, a first for the gathering. It came complete with a “startup alley” and pitch competition designed to bring the worlds of academia and startups together. Among pitches: a virtual reality program designed to bring a little bit of the outdoors to the institution-bound elders.


Technological advances have made many new aging technologies possible, said William Kearns, president of the International Society for Gerontechnology. Robots have a particular appeal.


“A robot can be a far more persuasive way to get a person to behave in a certain way — such as exercising — than an iPad or a cellphone,” Kearns said.


Canada’s federally funded aging and technology network, AGE-WELL (Aging Gracefully across Environments using Technology to Support Wellness, Engagement and Long Life), helped organize the event among a range of universities and organizations in North America.


Andrew Sixsmith, scientific director of AGE-WELL, said Canada is becoming a world leader in the field.


“The Canadian government has had the foresight to invest in this sector because they realize there is an aging population, and we need solutions that are going to address the challenges and the opportunities that brings,” he said.


“We are very keen in terms of the real-world impact of what we want to do, but also to demonstrate to the rest of the world that Canada can take a lead in this. I think Canada has put a lot of effort and investment into this and, down the line, that is going to pay off in terms of how it can benefit Canadian research, Canadian older people, the Canadian economy, but also benefit the rest of the world as well.”


Improving Overall Wellbeing


Joseph Coughlin, founder of AgeLab at MIT, predicted smart homes, robots and more will change the way people live and age.


“It is not about reminding me to take my meds, it is about having overall wellbeing and enabling me to do things, to improve the quality of life, not simply to extend it,” he said. “We should understand we are designing a lifestyle.”


Coughlin predicted the coming generation of elderly will demand technology to help support them and enhance their lives.


“Are you going to be as polite as your parents?” he asked. “No, you are going to expect a pill, a product or a policy to insure you live longer better because you have seen it your whole life.”


Along with potential, the field of gerontechnology comes with challenges: Among them, the ethical issues of increased surveillance on the elderly and the fear that technology will replace the need for human interaction.


Sixsmith talked about the need for further study about the implications of increased surveillance of the elderly – particularly in their own homes.


“The home environment has always been the domain in the individual, the space where you can be free from the observation of others. The introduction of surveillance technology breaks that boundary, and this is significant,” he stated.


Beyond nanny cams installed by concerned family members to watch elders is a future in which implanted tracking devices become more common. That raises new questions, said Coughlin.


Coughlin asked, “Where is privacy and dignity in all of this? How far do I push your dignity in order to ensure your safety? The new question is going to be: To chip or not to chip?”
