    Any science or computer themed book suggestions for an 11 year old who is really into all things Science and Technology? I was thinking something from Carl Sagan or Nick Bostrom but I'm not sure if they are going to be over her head…

    The Facebook study wasn't controversial because of what it showed. It was controversial because Facebook didn't even do a minimum of ethical approval. Participants did not consent to a study (at least not knowingly). So while it was legal (because the law doesn't care about whether you are aware of what you agree to) it was definitely not ethical. TL;DR: The FB study would have had the researcher kicked out of any accredited school anywhere for ethical violations.

    Interesting map re. the light to dark recognition example – looks a strategy for Democrats might to be to smuggle vegetables in to red states (or Republicans to steal them from blue states though that sounds harder…)

    Very nice subject ! There is a lot more in Donald Norman books about Human interactions with interface, he spoke a lot about errors prevention. For eg, imagine you have a form to fill. Rather than let the user badly fill it and sent it and then send it back on the form page if it has a missing field, prevent sending if there is empty fields. Prevent filling with erroneous data in a first place. This is way less frustrating for the user… and safer ! 😛 For the door example, Don explained that door which are on the street should open to the outside, so that people can escape fire inside the building faster and without having to think. Good error preventions can save lives 😛 Very good reading I recommend !

    Poor usability = every Apple product ever. Just yesterday I discovered with my rarely used iPad that I can't just copy a single file from my PC to the iPad without using iTunes to sync files over. But I no longer have the computer where I did the first sync, so it would delete all the files on my iPad if I tried to do a sync now. That is effectively an unusable device. And I have a whole litany of equally disastrous experiences with Apple products. How is this such a big company with such a popular following when their devices are basically unusable? boggle

    Don Norman would call virtual buttons having the appearance of real buttons a signifier – he now uses "affordances" for something more specific (I think that virtual buttons can be clicked, even when it doesn't look like it can, would be one example).

    I wish YOU the host of most scishow space videos than the girl who IS, your voice actually carries intellect and confidence in sharing it. Space girl just… feels like I'm listening to an overly excited but poorly informed 9th grade science fair contestant.

    The argument that people reveal more personal information in a Computer-mediated communication is a flawed conclusion (or interpretation) of the research. When people use CMC they have to use more detailed emotions (emojis, voice modulation, and turn-taking) as compared to a face-to-face interaction where the information is richer in quality (you could get more information of body cues, clearer facial expression, and contextual information).

    Modern GUIs have generally gotten pretty crappy affordances with the rise of minimalism. Buttons no longer have rectangular beveled outlines and even regular looking text elements often offer some interaction. Often times the only way to know if an element is interactive or not is to try to interact with it.

    A trash can or recycle bin as a place to put files to be deleted. Yet so many users get mad when the files in there are deleted, because that's where they were saving their important documents… x_x

    Relevant anecdote: I once took a uni course on professional writing for grant proposals, and one of our projects was to basically write an actual grant proposal for whatever field we were studying. As a comp sci major, I went with the idea of using pathfinding algorithms to optimize dynamic workflow layouts in software suites with the goal of enhancing usability and productivity. (Translation: having windows and panels optimally rearrange themselves when you open and close them to maintain your preferred layout without creating overlap for you to have to deal with.) Little did I know that my writing professor had studied human-computer interaction back when she was at uni, and she loved the idea!

    I didn't consider it a worthwhile goal, since I was just trying to pass the course (and honestly, I'm not so sure it was actually a good idea), so I never sent the proposal out to anyone. I do occasionally wonder if anyone would fund that research, though; I don't have more than the basic programmer's experience with HCI, though, to really know for sure.

    I think that multiple paths can slow down the gaining of expertise. Disconnecting your mouse while using vim will force you to learn effective commands quicker.
    Really important commands, like ctrl+{Z,C,V} in windows standard, shouldn't exist as menu items, because it enables people to keep wasting their time.

  • John Matthias

    That was amazing and deserves its own series. There were a number of things I didn’t know, and I thought I was keeping up to date. Thank you!

  • ResortDog

    Is it just me or should there be more operator training involved in this technology revolution instead of making "miracles" a moron can use?

  • UteChewb

    Not directly related to the topic. Mention should be made of the psychology of programming. I just want to mention an interesting book worth reading if you are thinking of becoming a programmer. "The Psychology of Computer Programming" by Gerald M Weinberg. It is dated in many ways but the insights on what makes programmers tick and the common management issues still seems relevant.

  • Carl Fink

    The discussion of gaze made me think: are you going to cover adaptive technology? As an educator I have to think about the blind, for instance, when designing online learning.

    I wish the developers of ANSYS workbench would watch this. It's a piece of software used for various types of computer simulation. It combined several different pieces of software. The user interface changes constantly from product to product. Even things like which mouse button you use to click drag to rotate the view constantly changes. It's so bad.

    When she said that computer can seem to be looking at us, the video pause and her eye is looking at the camera wide open.

    I thought the Facebook study was controversial because they didn't have consent to experiment on the users in the first place. Not telling your subjects that they are participating in an expirement is preaty unethical.

  • AshnSilvercorp

    I can tell you one thing about Facebook though.

    seeing "Ad coming soon" when I'm passing by a video, make's me immediately close facebook, and absolutely mad…

    This video is RIDICULOUS!You careen in highspeed through a topic called ERGONOMY?You bang bang bang display bang bang bang text on bang bang bang the screen bang bang bang without bang bang bang giving the viewer the bang bang bang chance to bang bang bang read and bang bang bang understand what you display while at the yadda yadda yadda time you yadda yadda yadda dump tons of yadda yadda yadda into the yadda yadda yadda viewers yadda yadda yadda ear? You do not give the slightest chance for the audience to connect the seen and heard information!THIS is NOT ergonomy!This is just a noisy, yet colorful tsunami of merely nothing, a huge pile of waste, that cloggs the brain.Its a big fail.

  • northwesteneer

    Apparently YT comments do not support any line breaks anymore. Leaving no space after the . makes me look like a moron, unable to write properly.

    As for humans treating robots as if they are human and getting mad when they break social norms; we already have a built in solution to this, pets. If the robots seem more like intelligent pets (they are small, they are kind of cute, and they talk in simple sentences) then we will likely give them more leeway.

    When my dog steps on my foot and doesn't apologize I'm upset, but not as upset if my wife did it.

    Multiple choice easier than fill in the blank? What university did you go to? Multiple choice are often considered the hardest type of question (excluding things like essay questions) because they are often designed to trick you, or at least cause you to "recognise" multiple answers, and second guess.

    PBS Digital Studios should do a channel about Computer Science and Programming. The only channel on Youtube that exists about that is Computrerphile , but i want more. It makes perfect sense the channel can do videos on Programming Languages, Data Structures, Algorithms, Design, Logic, Artificial Intelligence, Computer Graphics, Software engineering, Virtual Reality, Math for CS, and many more topics in Computer Science, and Software/ Programming and Technology. There is no reason why not to do it.

    I have recently finished a instruction to HCI (human computer interaction) in my degree. In this video, it did mention, areas I've been tought, a good video from crash course.

    Telephone numbers of the Public Switched Telephone Network were not invented to be in chunks for our memory. They are a combination of Area + Exchange + Trunk + Line. The primary consideration was not memorability – it was clarity when spoke, the way we say "charlie, bravo, sierra" back when switchboards were operated by an operator. Exchange names were alphanumberic (my family's number was "Bixby" for 14) on the keypad, and area codes were assigned based on time it took to dial on a rotary phone, with Los Angeles (213), New York (212) and Chicago (312) getting the fastest numbers to call. The area code was grouped by function (you didn't need to call it if you were on the same exchange, not as a memory tool.

    "A good interface once you gain experience is one that offers multiple paths to accomplish the same task." Reminds me of a job I once wasn't hired for: I had an online skills test for Quickbooks and I guess I didn't use the normal path the online test expected me to use to accomplish the ask.

    I hate looking people in the eye. Most people say they are uncomfortable around me because I don't look at them. It makes me a mutual gaze failure. I find it intrusive – I want to give others their privacy and feel ashamed to interfere in their lives.

    i have seen basic to understand doors say push or pull on them

    i think people just dont know how to use doors

    thx for this interestingly ha bisky vid i loved this a lot and even with automatic doors you can sometimes push them or pull them so they still have directions on them

  • gregory rovira

    "Psychology can help us" that is an scary thought… history shows how it has been a government and media tool to control population, push mind/mood altering drugs and do things that degrade humanity. And we are going to rely on them to solve ethical problems having to do with something as powerful as advanced computer technology? Shrinks are gonna help?
    PLEASE!

  • TelFiRE

    Seems very few care enough about usability. Things were getting better for a bit, but now they're getting worse again.

  • Blazerona

    I believe the only emotional influence a computer should have is to help you know how it works and nothing beyond that. It is a tool to use, not a tool that uses you.

  • Giga Joules

    Hmmm…. The mutual gaze thing is definitely valid.
    As someone with ADHD it definitely makes a difference if the speaker in a video is addressing the camera, though I've never thought about it before this.

    "Delete? Remove? Trash?"
    You know what, command line interfaces are still common, used even by non-technical people, in the form of bots in chat rooms. These bots do various things, some for fun (eg. !roll -> rolls a dice), some have a practical use (eg. !faq shows some commonly asked questions of a software). Even it's simple as that, there can still be design choices that improve usability – the easiest one being allowing aliases (i.e. alternative names or spellings) of commands. I can make my bot delete something if you type "delete", and I can make it do the same if you type "del" "remove" as well.

    It'd be very annoying to fail to see your !coins for five minutes only to know the correct command is !coin .

    Since about 95% of posts are mere reposts, is it really surprising that supplying negative posts results in more negative posts? I expect that this has nothing to do with altering the users' behaviors.

    – Welcome to our "Windows 10 course for absolute beginners". To start, click on the Start button with your mouse. Or press the Windows key.
    – Where are they?
    – The Start button is the thing in the bottom left corner of the screen. It does not say Start, or look like a button, but you'll figure it out…
    – And the Windows key?
    – Easy! It has a picture on it. Looks like 4 tiles, or maybe a flag.
    – Thanks! I don't know what I would have done without you! It's not like this thing has a tutorial…
    – Of course not! We are in the 21st century! Tutorials are so 1995!
