Week 9: Examples of bad and good HCI

With technology developing rapidly, we find all sorts of new ways to improve our lives and how we interact with technology. With technological innovation, we might witness the creation of something life-changing and spectacular or something that just no one even asked for. I'll try to bring examples of both worlds.

Firstly I'd like to bring a good example of HCI - eye-tracking. I recently watched either a video on YouTube or a documentary on Netflix (can't really member which) that showed how eye-tracking technologies have changed the lives of people suffering from illnesses like locked-in syndrome. Locked-in syndrome is a condition where people have full cognitive ability but they are unable to move or speak due to paralysis of voluntary muscles. So usually they can only move their eyes, and that's about it, although some can't even do that. They are literally locked in their bodies unable to move and communicate with others. But thanks to eye-tracking, people that have been paralyzed for years without any sort of means of communication, finally have gotten a way to express their thoughts and feelings. Usually, they have a tablet in front of them with a keyboard that registers input by tracking the person's eye movement, so if they want to type in "hi" they just look at the corresponding letters. An example of such a tablet:

And seeing real-life examples of people using these was really eye-opening and made me appreciate what we are able to do with the help of technology. 

But as mentioned, some people can't even move their eyes, so the only way they can communicate if a chip is planted on their brain or a brainwave headset is used. An example could be Elon Musk's Neuralink, which already seems quite promising if we leave aside some of the ethical and security questions.

An example of bad HCI or UI is, in my honest opinion, smartwatches. Yes, they are convenient for tracking your steps and heart rate (which you could just use a fitness band for), and whatnot but as a smart device that you could use apps with and use as a replacement or extension of your smartphone, I find them extremely lacking. I have tried out some smartwatches, including Apple Watch, and they are way too complicated, the layout doesn't make sense at all for such a small screen and imo they aren't worth it at all, it's just a struggle to use it and I believe you can do more reasonable things with your money.

And while on the topic of "smart devices", I still don't get why some smart TV producers still make these kinds of remotes:

I have had one of these, and altho yes, it isn't the newest, still, I see a lot of smart TVs having these. They are overly complicated and you don't actually use 80% of the buttons You could just display some of the stuff on the screen instead of making a specific button for literally everything on the remote and having users search for a specific button on the remote. After all, it should be a "smart" TV. Changing this would avoid these kinds of situations:

Week 11: Privacy and censorship

This week's topic was censorship, privacy and the Internet and I'd like to talk about examples of both censorship and privacy. The first thing that pops into my head regarding censorship is the famous Chinese app TikTok. Amongst TikTok already having tons of privacy issues and security risks, TikTok has also been caught censoring its content that would be okay in the Western world and Europe but wouldn't be in China. As TikTok is owned by the Chinese company ByteDance, it cooperates with the Chinese government and they have said this openly before, although they don't really specify exactly how. But TikTok users have noticed how some content that is being posted is heavily censored. Examples of this are the BLM and ACAB movements and Hongkong protests. The app has only one main feed that you can't filter yourself, it just feeds you content based on your watch time, likes, and personal data. So when these movements were at their peak people started noticing how all o...

Week 8: IT professionals in Estonia

This week's topic is IT professionals in Estonia. As the word "professional" can be defined in many different ways and the definition varies from person to person, for simplicity, in this blog I'll focus on IT professionals who have some sort of an IT degree, although there are a lot of professionals that don't have any sort of a degree. In the last 20 years, the demand for IT professionals hasn't decreased, already at the start of the millennium we were lacking in specialists in the field and we still are now, as the demand increases with the rapid growth of IT. The following graph is from a presentation that one of our lectors - Ago Luberg - gave at both the 2020 and 2019 IT-ametite päev or IT-career day. It's a summary based on a research done in 2019, with the purpose of finding out what the future of IT in Estonia is. Prognosis of the demand for people in IT for the next 10 years. The blue bubbles represent the number of people who on average graduate...
