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 5: Copyright reform

In today's blog post I will be sharing my opinion on the book The Case for Copyright Reform by Christian Engströmand Rick Falkvinge and on copyright issues in general. The book starts off with a claim that today’s copyright legislation is out of tune with the times and I must agree with that. There is a dire need for a referendum when it comes to copyright laws, as they are threatening our privacy. And to me, a person who isn't really familiar with all of these copyright laws, it seems that these new laws aren't being passed partly because of big corporations who are afraid to lose part of their income. In the second chapter they bring out some key changes that they propose: Moral Rights Unchanged - when it comes to moral rights, I think these don't really need a change. As said, no one should be able to claim that they are the author of someone else's creations. ”Give credit where credit is due” Free Non-Commercial Sharing - I agree with this point a lot, the curr...

Week 1: Three IT products that resulted in a failure

In the innovative world of IT where the competition is more intense than anywhere else, it is bound that most companies and products will inevitably fail. I will talk about some interesting cases where games caused an uproar upon their release as they sadly failed to meet customers' expectations. The first one on my list and additionally the most recent game is Cyberpunk 2077 which was released less than 2 months ago. Cyberpunk is an open-world action role-playing video game that was released on PC, next-generation consoles (Xbox Series X and PlayStation 5), and older consoles like PlayStation 4 and Xbox One. The game was already announced in 2012 and the game gathered major attraction pretty much from the start. The game was in development for over 8 years and the hype for the game grew especially as the developing company was CD Projekt Red, a company that is infamous for their successful Witcher series. I also had really high hopes for the game knowing that the same company who...
