How Smart Homes Alter Human Behavior

Shouldn't intelligent appliances require less fiddling to get the settings just right?

For decades, humans have been building and modifying machine learning models to perform a variety of tasks. But while we’ve been modifying these AI models to suit our needs, the question remains: how are these AIs changing us?

A group of researchers in Canada recently sought to explore this relationship between AI and human behavior by focusing on an AI that’s close to home: the smart home system.

These systems rely on a concept called reinforcement learning, whereby the AI is “rewarded” for good behavior. In the case of a smart home system, this involves adjusting the environmental settings until the AI “learns” to set the temperature and other parameters according to human preference.

However, reinforcement learning is similar to the way that humans and others in the animal kingdom use to learn behavior—meaning that both human and machine are constantly altering their behavior based on their environmental surroundings and the new information they receive.

“In a smart home environment, both [the home smart system and the human are] attempting to maximize the reward that they receive,” explains Francois Rivest, an Associate Professor in the Department of Mathematics and Computer Science at the Royal Military College of Canada in Kingston, Ontario. “So we started asking whether, given such dynamics, the human’s behavior could end up changing as an outcome.”

Rivest and his colleagues sought to test these dynamics through a series of simulations (ironically, using a machine learning algorithm to study a machine learning algorithm). In the simulations, a human went about their regular activities, and the smart home system was tasked with learning the human’s preference for room temperature.

The results, described in a study published last month in IEEE Transactions on Artificial Intelligence, show that smart home systems are very good at predicting human preference. However, if the smart home system was just a bit off in predicting a human’s preference, the human and AI developed misaligned behaviors. “This led to more time spent by the individual changing temperature and activities than without the smart home system—the opposite of the smart home objective,” notes Rivest.

The researchers also explored scenarios where two humans with different preferences were in the smart home environment at the same time. In such instances, the humans actually changed the order of their tasks to minimize their time spent changing temperature.

Ali Etemad, an assistant professor at Queen’s University who was involved in the study, notes that there could be a lot of benefits associated with smart home systems. “I think incorporating intelligent elements in homes can have significant positive outcomes ranging from health and safety to security. But there may also be unintended negative outcomes, which scientists should study and plan for,” he says.

Next, the researchers are interested in developing more advanced models to study how AIs can alter human behavior. “It would be very interesting to collect some real data in the future as well, and do a comparative study against our simulations,” says Etemad.

Smart Home devices and AI is not altering the human behaviour. When we go to Enquiry section and ask for help, AI and smart devices will guide us in Natural Language and we need not have to be aware of knitty gritty of Technology and Coding. Only thing we have to be literate and have language skills. Now

We are finding Arts students taking up professional computer training programs and getting good job in IT (Information Technology)

for both hardware & software jobs. Arts graduates have good memory and language skills and can be easily converted to Tech Savvy.

What we need to operate smart AI devices at home is good Observations and common sense of Knowledge. High School level Knowledge is essential and need not have hi-fi degree to Operate smart AI devices at home .

Human Emotions should not be mixed up with Inert objects in operating smart devices. Emotions and Technology are two different things and these

Qualities should not be mixed up with one another.

Reminds me of how the original electrification of the home changed behaviors. From hiring help to wash and iron cloths and the men beating the rugs outside, to the women doing the laundry and ironing the cloths and vacuuming.

Now that recorded sound has become ubiquitous, we hardly think about it. From our smartphones, smart speakers, TVs, radios, disc players, and car sound systems, it’s an enduring and enjoyable presence in our lives. In 2017, a survey by the polling firm Nielsen suggested that some 90 percent of the U.S. population listens to music regularly and that, on average, they do so 32 hours per week.

Behind this free-flowing pleasure are enormous industries applying technology to the long-standing goal of reproducing sound with the greatest possible realism. From Edison’s phonograph and the horn speakers of the 1880s, successive generations of engineers in pursuit of this ideal invented and exploited countless technologies: triode vacuum tubes, dynamic loudspeakers, magnetic phonograph cartridges, solid-state amplifier circuits in scores of different topologies, electrostatic speakers, optical discs, stereo, and surround sound. And over the past five decades, digital technologies, like audio compression and streaming, have transformed the music industry.
