5 Uses of Artificial Intelligence in Our Every Day Lives

Nola Palestrant, Tamalpais High School

Artificial Intelligence (A.I.) is a branch of computer science that was created in the 1950s. Unlike previous computer programs, A.I. allows machines to think and behave like humans without being explicitly programmed on their courses of action. A.I. strives to mimic humans’ reasoning, intelligence, decision-making, learning, and perception abilities. There are many complex techniques being used in A.I., including Neural Networks, Machine Learning, and Deep Learning. A.I. has been the subject of many controversies for its security with personal information, fairness, and misinformation, and has been vilified in numerous books and films. Regardless, Artificial Intelligence is becoming increasingly common in our modern world. Here are some ways we interact with it in our daily lives. 


  1. Music Recommendations

So many of us listen to music daily, and platforms like Spotify and Apple Music allow us to play the songs of our choosing at any moment. These services are so popular that they generate billions of dollars in revenue every year. The platforms couldn’t be the successful programs that they are without the use of Artificial Intelligence (A.I.). 

Music platforms use A.I. for a variety of functions. A.I. provides personalized recommendations based on content the user frequently listens to. It’ll suggest what it predicts you’ll enjoy and avoid what you’ll dislike. Through reinforcement learning – which involves rewarding or punishing certain behaviors – these services will curate songs that are a good fit for you. Along the same lines, platforms will use A.I. to generate specific playlists based on your taste. 

Music platforms use Natural Language Processing (which helps computers to understand text) and Deep Learning (a way of processing data similar to the human brain to link messages that are not explicitly stated) to enhance search capabilities. When you search for a song, you don’t need to write the title entirely correctly for the program to answer with what you want. A.I. will establish connections between the words you write and the content you intend to see. 

As A.I. continues to grow, it will further transform the music industry. Currently, A.I. is revolutionizing production, breaking apart components of songs, and telling musicians which music will most satisfy their fans. As A.I. progresses, songs will be created entirely by A.I., underscoring the need and importance of musicians.


  1. Virtual Assistants

Siri, Alexa, and Google Assistant were some of the first Artificial Intelligence (A.I.) to noticeably make its way into our homes. Released in 2011, 2014, and 2016, respectively, these devices revolutionized our interactions with technology. 

The internet is no longer just at the tip of our fingers - it's at the tip of our tongues. With only a few words, users can know the weather next Tuesday, the directions to their favorite restaurant, or the complex workings of organic chemistry. Virtual Assistants allow tasks to be completed or questions to be answered hand-free and with ease. 

Virtual Assistants like Siri, Alexa, and Google Assistant utilize a variety of algorithms to transform our words into data and then respond to its commands. This procedure, known as Natural Language Processing, or NLP, enables computers to understand words or text, thereby allowing conversation between technology and humans. Other programs such as Pattern Matching Algorithm (a sub-part of NLP) and Natural Language Generation (allows the A.I. 's response to be comprehensible and thorough) are examples of Artificial Intelligence techniques in these Virtual Assistants. 

In combination with A.I., these technologies can evolve into more efficient and dependable machines, with the potential of further advancement. The algorithms Virtual Assistants run on are constantly advancing, and as the data used to run these programs is trained even further, its capabilities will continue to improve. In addition, recent A.I. like ChatGPT could be integrated with older ones, creating increasingly powerful Virtual Assistants. 


Facial Recognition on personal devices


  1. Facial Recognition

Facial recognition, most commonly known for its use on phones, is an A.I. based technology that allows a person to be recognized despite never being seen in those same clothes, that same hair, or that same lighting. We use facial recognition (also called Face ID) to unlock our phones or purchase apps, but it can be used for anything pertaining to identity verification. Although we don't think much of it, facial recognition is a complex process. 

The computer analyzes faces using their visual geometry, which is the relationship between different facial features. A.I. compares the data gathered from the original image to all the faces in the picture, finding the one that is a match. Deep learning processes enable faces to be transformed into numerical expressions. They are then used to look for similarities between the known person and the expressions of every other face.  

In addition, A.I. is used in facial recognition to separate the subject from the landscape and objects in the background. Facial recognition can also be used in broader ways, such as in searching for lost people and finding criminals. 

Currently, facial recognition is being developed to recognize when a person is lying. It does this by discerning subtle changes in facial expressions. As facial recognition becomes more precise and widely used, it can help prevent hacking personal items, as the only way to access the material is by being physically recognized as the owner. Facial recognition could be used to detect tiredness and other problems that may affect driving abilities, thereby reducing injuries. 


  1. Navigation

Navigation apps have become a critical part of modern transportation. Whenever we go to a new place, we no longer pull out a paper map; instead, our phones or cars direct us. 

Immediately upon setting the destination, we are told of the traffic conditions, when we will arrive, and how long the journey will take us. And if you take a wrong turn - don’t worry! - the map will adjust your route automatically. 

Artificial Intelligence (A.I.) is instrumental in making these features available. Using data from specific areas in the past few weeks, the map will analyze the likelihood and severity of traffic, giving the user an accurate ETA. In cases when traffic is high, A.I. suggests alternate routes to get you to your destination faster.

A.I. also takes into consideration road conditions, speed limits, and stop signs or lights. This allows it to decide the fastest route, not simply the shortest. It can also adjust to changes like road closures, crashes, or adverse weather.

This A.I. works using Graph Neural Networks, a program that can model changing data from the real world by translating it into graphs, and predict what will happen next time. It gathers this data through satellite imagery, crowdsourcing, user location data, and partnering with other companies.

In the future, A.I. could further analyze traffic data for common areas of traffic and accidents. This would enable navigation apps to route the user around such incidents before they occur. A.I. could also merge with satellites, combining data from things such as weather conditions and establishing routes more efficiently.

  1. Self-Driving Cars

Partially self-driving cars have risen to prominence over the last couple of decades, with the promises of reducing crashes by eliminating human error and expanding the accessibility of transportation. They “sense” their surrounding environment, aiming to adapt to and overcome any challenges, in order to control cars in the same way as humans. 

The unpredictable and varying nature of human driving has inspired the development of self-driving cars, which rely on Artificial Intelligence (A.I.) to travel safely. Predictive modeling is the ability of A.I. to analyze patterns and anticipate future events. Predictive Modeling enables the car to anticipate the behavior of other cars and adjust to problems as they may arise. They use A.I. to make decisions in the moment, aiming to react to changes in their environment appropriately.

With the help of sensors feeding data to the computer, A.I. can recreate the car's surroundings. This allows it to recognize objects like crosswalks and traffic lights, and heed such signs correctly.

Many vehicles on the road today are already partially autonomous. Features including emergency braking and lane assistance are already widespread, with A.I. as an integral part of their success. These features have helped to keep drivers safe, and they will continue to improve. 

Although completely self-driving cars are not yet commonly owned, if you live in a big city like San Francisco or Phoenix, you’re likely to see them being tested on the streets. Self-driving cars aren’t popular at the moment, but they could become much more common in the upcoming years, as products currently being tested are brought to market.

Virtual Reality, Augmented Reality, Artificial Intelligence, 3D Animation, and Einstein's Theory of Gravity

  By Shoshana Harlem, Terra Linda High School
http://marinscienceseminar.com/ai-vr-3d-amazing-applications-for-understanding-physics-with-david-levitt-ph-d-9-25-19/



Headsets are used in virtual reality.

     Virtual reality is when a computer generates an artificial simulation. By simulating a person's vision and hearing, virtual reality makes a person feel like they are experiencing the video game firsthand. To experience virtual reality, people wear a headset. There are two main reasons why people use virtual reality. One is for entertainment and gaming (E.g.: computer and video games, 3D movies) because it helps create and enhance an imaginary reality. Virtual reality is also used to help train for real-life situations by creating a simulation. This helps people be able to practice the situation beforehand, and therefore be prepared if and when the situation comes up in real life. Pilots often use flight simulators to train for real-life situations.

Augmented reality
     Augmented reality is a technology that uses computer-generated enhancements in order to give people an opportunity to interact with the situation. Augmented reality is used in apps and electronics. It is used in many situations such as to display the scores on sports games, have 3D emails pop out, along with phones and text messages on electronic devices. People are also using augmented reality to create motion activated commands on electronics, such as Iphones.

Artificial intelligence 
     Artificial intelligence is an area of computer science that creates machines that work and function like humans. It runs smart machines. Artificial intelligence is used in everyday lives such as SIRI, google search, and even self-driving cars. People have conflicting views on artificial intelligence and often debate whether it is safe. Artificial intelligence is good because it helps people complete tasks in their daily lives, which saves people time and energy. Another reason why artificial intelligence is good is because it helps people with disabilities such as helping visually-impaired people or people with hearing impairments with translations. For people who can't communicate that well, artificial intelligence can provide communication technologies. On the other hand, some people argue that artificial intelligence is not good because sometimes it fails and can land people in dangerous situations. For instance, a self-driving car might not see another car when merging into a lane and might therefore cause an accident.

3D animation helps explain Einstein's Theory of
Gravity. 
     3D animation can help people see Albert Einstein's Theory of Gravity. Einstein visualized that gravity is not a force and instead is a curvature of time and space which is caused by energy and mass. Einstein said that gravity and acceleration are the same thing. Meanwhile, Isaac Newton thought that gravity was separate from acceleration. 3D animation allows people to run physics experiments to test Einstein's theories. The physics experiments show how gravity works, where people's weight comes from, and the effect of mass.

     To learn more about virtual reality, augmented reality, artificial intelligence, 3D animation, and Einstein's Theory of Gravity, come to the Marin Science Seminar at Terra Linda High School in room 207 on Wednesday, September 25. David Levitt of Pantomime Corporation will be speaking. Join us and learn!
