When you launch the application, it shows the latest xkcd that is published at the website. You can browse other xkcds as you would do it at the website. It also utilizes features new in Windows 7 such as jump lists, thumbnail previews, and thumbnail toolbar to provide better user experience.
In order to display comics and related information from xkcd. We need to retrieve the comic title, ID, image location, and the mouse-over text. As you can see from the image below, we need the following XPath expression:. After that, we need the h3 and img elements to retrieve the necessary information. Here is the corresponding code:. As the previous source code snippet shows, we have a class called xkcd which knows how to get the required information.
However, the form which displays it never instantiates the class directly. Instead, all the interaction goes through the xkcdService class. This class exposes the following methods for getting an xkcd:. As getting the source of a webpage requires some time, all the above methods are executed asynchronously. When an xkcd object is available, the xkcdService class fires the xkcdLoaded event and passes the downloaded object. Apart from this, the xkcdService class keeps track of the current xkcd ID, and exposes two properties indicating whether there is a previous and next xkcd or not.
Also, it keeps a cache of the loaded objects so that if the object is requested for a second time, it is returned instantly. The code snippet below shows how all this is done:. CD Read Rate 3. It used to be dynamic and the greater the bars, the faster would the progress bar with the percentage load. The second one used to be active only when the game was installed from a CD.
Needs citation. Probably to indicate the amount of memory free during installation. I will research a little more on this and update the answer.
The thing to keep in mind is, Bars were a design trend back then and were used mostly everywhere, including indicators to Battery on Nokia devices. More Bars always meant something positive. The question is in my opinion is that the how the different progress indicator design differ?
It is important to define what consistency means and how it is applied in UX design. You can define a specific rule for using modal windows e. But you will find that in one instance you might have different needs for accepting user input e. It also becomes more complex when you have many different functions and features that form various types of user workflows. I think the key here is to try and map out all the different scenarios and make sure that you can apply any rules consistently or adapt them when you need to.
This way you'll be able to avoid problems with consistency. K Given your question, is this the sort of thing you're trying to do? E The EU has plans to encourage manufacturers to use as common charger format: common mobile phone charger 1 common mobile phone charger 2 This also has environmental benefits.
B If there's no way to get around submenus, the key is to provide a clear visual difference between levels and making it clear which main menu the submenu corresponds to. Here's an example that provides a clearer differentiation between levels which uses a combination of the above approaches: Now, this example isn't infinitely scaleable, but a properly designed information architecture should not really require much more hierarchy than this. E Non-linear interfaces have pros and cons that go beyond the UI layout.
Consider your intended and likely use cases carefully. I've tackled similar requests a variety of times over the years. There are occasions where the desire for non-linearity comes from the users, but they are rare. What about if two users are editing the same object? How do you reconcile or merge the changes? Vinnl on Dec 19, prev next [—]. So I guess that'd be the second, third and fourth from the bottom at the start of the video, but I'm listening without sound so perhaps someone can confirm.
I think this research shows that you can influence perception of time without resorting to outright "making up" the progress bar. You can imagine using this technique not to lie about progress but just to make short progress bars appear to move faster.
I spent several hours in Google Analytics yesterday. It's been a few months since I've used it, and I remember thinking that it seemed a lot faster. They've recently refactored their UI, and possibly done some system improvements, who knows.
But after looking at this research, I can see that they've also taken advantage of similar techniques to make their loading bars seem faster. Two significant figures shouldn't be used to measure a perception that is subjective and probably not even linear. Unless they have a scale of "perceived speed to actual speed" for regular progress bars, that they're using to gauge the enhanced ones?
You made me curious so I dug into the paper. This was compared against a standard, solid color progress bar. Specifically, if a user felt the ribbed progress bar was faster, its duration was extended to slow it down. Conversely, if the user felt the ribbing was slower, the duration was reduced to speed it up. Equal responses left the duration unchanged.
No thanks. I'm not interested in the manipulation of perception. I'd like a progress bar to actually report on progress. If you can't do that, don't feed me bullshit blinking lights, and pat yourself on the back. Just tell which part is hanging up, so I can either clear the bottleneck, route around it or throw everything in the trash. I'm torn at this point, about which non-progress bars I hate more these days, Apple's or Microsoft's. Reporting 20 minutes and taking 90, opaque, inching along pixel by pixel, and not telling you anything about what's slow, or whether there are parts to the process.
Just one stupid line, and if it fails in the middle, start over. Is it unzipping, checking the integrity of file hashes, connecting to the internet, not connecting and waiting for a time-out, compiling open-source packages for this particular chip set? One thing's for sure, I've been promised so many minutes, and instead lost hours. Alright, fine, but is there any reason to think you're anything like a typical user? Unless you're writing a programming tool it's very unlikely that most of your users are highly technical users who think like a programmer.
As an addendum, I was once in a position where I'd have to provide essentially all the support for software I developed. That's no longer the case but the mindset of avoiding designs that are likely to confuse the user and thus lead to people bothering you to ask about them stays with me even a few years later.
One of the things I've liked about Linux though some distros have changed this over the years is how with updates within a package manager GUI like system updates, or installation of software , it would default to just a progress bar, which was usually fairly accurate, and maybe some text above or below it showing basic info on what is happening. So you not only got a nice and usually accurate GUI representation, but if you wanted, you could also see extreme detail of what was going on or why something was taking a long time maybe it's trying different servers to find a dependency, or it's downloading a file and something is slowing it down - or maybe your router has crashed, and its just sitting there, etc.
