Why do users click randomly and rapidly when an application hangs?

  • This question came to me when I witnessed a collegue's behaviour on an application freezing due to a large operation. And it's something I've certainly done myself.

    An app freezes for more than a couple seconds and we start clicking at it. Repeatedly. Often in no particularly meaningful place, as if that is going to somehow "wake it up." Even more bizarrely, users who have learnt that all those clicks will queue up and fire off when the program responds again will specifically choose to click in an area that has no known interactive ability (like an empty part of the chrome).

    So users are clicking when they know it will have no effect and in areas that they know has no function, in hope that it will bring their program back to life. We all do it. But why?

    Also, it seems the longer a program stops responding, the more random actions we start to throw at it. After a few seconds, it's clicking. Soon after, its keyboard tapping (the spacebar seems a favourite; but conversely people seem reluctant to try the Enter/Return key). Then the Escape key in heavy rapid fire (power users may break out the Ctrl-Alt-Del or other combos at this point).

    Until finally, we reach the guaranteed fix-all of unresponsive programs [citation needed]: kicking the tower.

    Why do we do this?

    EDIT Excellent answers all-round! Can only choose one accepted, but I've upvoted lots of others too.

    Poke him with a stick to see if he's dead....

    Just something I sometimes do : ctrl+c ctrl+c ctrl+c, just to make sure :)

    OCD... I am telling you.

    When I used Windows, I remember if a program froze, it wouldn't inform me until I clicked the frozen window again. Only then would the top bar change to "Not Responding" at which point I'd conclude it had in fact crashed. The clicking might be a way to force a reaction from the program: Either finish your job or tell me I'm screwed.

    I did some experiments on an electo/mechanical interface in the early 90s and observed the same 'random button pushing'. So it's not about computers per se. I have no idea 'why' they were doing it and neither really did they...

    "_It seems the longer a program stops responding, the more random actions we start to throw at it. At first it's clicking. Soon after, its keyboard tapping._" -- This is similar to people frantically hitting the telephone hook when the line goes dead.

    I would fidget with ctrl+c on a computer and the clear in a calculator if those actions offered low levels of feedback http://ux.stackexchange.com/a/11694/8159

    There is also another step for some people: hitting the computer, especially the screen. Like if there was a badly plugged piece of hardware causing the issue.

    I click in frustration as if to say, "Pay attention to me!"

    Oddly... I don't. Window manager grays it out, its unresponsive, proceed with `xkill`.

    This is indeed a great question, with lots of great answers.

    "So users are clicking when they know it will have no effect and in areas that they know has no function, in hope that it will bring their program back to life. We all do it. But why?" I think frustration plays a big role here. I do it myself. I just click the damn program full of anger and think to myself: "Why is this sh** not working???" Now I know, that rapid clicking doesn't improve my situation. But it's somehow a nice way to release my anger "on the program".

    once fixed my optical drive this way... clicking is less likely to injure one's hand on hard computer surface. computer is un-traveled individual that understands the native language of click and double-click, but don't understand a damn word of clic-clic-clic-clic-clic-clic-clic-clic-clic-clic-clic

    I believe the reason users click repeatedly is because they are accustomed to anticipating an update every time they perform an action and the clicking allows to find out if there is an expected behavior from the app or at least some reaction which informs them about what they could do.

    Also this funny image might give an answer :)

    enter image description here

    With regards to the space bar key,I think it has to do with the large size of the key (Fitts Law) and the ability to easily click it again and again in the hopes of getting a reaction. With regards to the enter key, it is generally used as an affordance to move to the next step and users might hope that repeated presses of the enter key will help get past this troublesome stage and load the next stage which is hopefully working.

    Finally the escape key is pressed as it has become the denotation to escape from what the user is doing on the a computer or the close something and hence an attempt to escape from this situation. To quote this article which talks about the psychology of the escape key

    The button dates to 1960 and was created by I.B.M. programmer Bob Bemer. It was intended to help programmers switch from one computer language to another. Later, the key evolved and literally became an escape tool: users now press it to stop what function they’re engaged in, no matter what operating systems and brands they’re using. The naming of the key was likely meant to suggest a sense of panic. I personally think the language is effective: it’s powerful and to the point, somewhat fanciful and a little dreamlike–and definitely not as alarming as a button that would scream “help!”

    Also to quote this NY times article about the ESC key design

    Why “escape”? Bemer could have used another word — say, “interrupt” — but he opted for “ESC,” a tiny monument to his own angst. Bemer was a worrier. In the 1970s, he began warning about the Y2K bug, explaining to Richard Nixon’s advisers the computer disaster that could occur in the year 2000. Today, with our relatively stable computers, few of us need the panic button. But Bob Frankston, a pioneering programmer, says he still uses the ESC key. “There’s something nice about having a get-me-the-hell-out-of-here key.”

    Finally the control +alt+delete option might be used in an attempt to shut down the application and start afresh.

    I believe the user's mind flows in this pattern

    let me check if there is a reaction (click stage) --> let me try to get past this stage (enter key) --> let me kill this application at the local level (ESCkey stage) --> let me shut this application at the root level or computer level (control-alt-delete stage)

    Spot on. The moment an app doesn't respond, the average user is completely in the dark. In order to determine if the app has returned to normal expected behavior, the user tries something that normally gives them visual feedback: clicking. No response? Wait a second and click again. IT won't respond quick enough so just repeat this process ad infinitum until something changes ... for better or worse.

    I personally do it more to express my anger at the machine. Sort of a "take this" action. I know this because my tapping on the spacebar isn't designed to be functional, it's designed to beat the crap out of the keyboard.

    @Josh +1 internetz you just made me laugh out loud in the office.

    @plainclothes I am an IT professional, and I do this. Although maybe for a different reason. Its part of my reasoning process from working on and supporting less than good products. Perhaps there was a pop-behind that stole focus, lets see what trying to steal focus does... It either (In Windows 7 its faster) gives me a "not responding" if it hung or is working really hard, or it flashes a few times if something else has stolen and has a hold of focus.

    @AthomSfere but you do it as a quick test *because* you know what's going on (or might). In other cases, as Josh pointed out, people just bang on the keyboard and/or mouse to vent. Also reasonable ;)

    @plainclothes Yes, I was just adding it for what to me is whimsical truth that we all do it, for one reason or another. But I guess better said is "Insanity is doing the same thing over and over and expecting different results"...

    So in sense, we need to design a UI that is click-tolerant, I mean, something that would not break on thousand clicks. :-)

    @Josh I totally agree, this is for me comparable to the reaction when one of your appliances at home is not working and you give it a shake and some "slaps" out of frustration/anger :)
