Homework 2: Good Design vs. Bad Design
The elliptical that I use most often at the gym has a pretty bad interface, in my opinion.
What annoys me most about this interface, is that there is no "Pause" option. The only thing you can do is just stop going for, at which time the main screen will say "Pedal Faster" and ultimately, the machine just turns off. There is no indication of system status at this point. I think it would benefit from having not only a pause button, but a visualization of how much time you have to stop briefly to refill your water bottle, or tie your shoe for example. Another problem is the reset button. I find the reset button to be sort of useless. I think a Pause/Stop button should replace it there, because you could hit pause once to just pause it and then twice if you really needed to reset. Rarely do I need to reset a workout, and too often, I do it by accident. When I do it by accident, there is no redo option. There is no recoverability in this sense. It doesn't even ask me if I am sure I want to reset it. As soon as I hit the reset button, it automatically resets. Additionally, the buttons are not very responsive. They're operated by a very light touch, and physically, you have no idea if you are even doing anything because they are not even buttons, just sensitive spots on the interface. Generally, this problem is solved by the visibility on the screens, which usually respond to your touch, however, I think an actual physical response to the button could be more helpful.
Snapchat is a photo sharing application that allows you to send pictures quickly to your friends for 1-10 seconds, and then the photo goes away. It's useful for quick, funny, communication purposes. At a first glance, this design is pretty straight forward. The icon at the bottom right indicates your "inbox," and the one on the right indicates more menu options. The center button is for taking photos. However, if you hold down the center button, you can also take a video. The first time I realized this was purely by accident, when I pressed down on it for too long. This was pretty bad in terms of predictability. It is also not consistent across any other photo/video taking software I have used on my iPhone. There is always a visible option to switch to video, which was not apparent here. Additionally, once you have taken the photo, you can draw on it, or type a message.
It's sort of clear that you can draw on it with the pencil icon in the top right, but the typing feature is totally hidden. You access it by simply tapping on the picture in the general vicinity of where you want the bar of text to come up. But it is not predictable and I've found out about this feature by accident as well.
Next, there is a pretty useless feature where you can view a list of your friends.
You hit "My Friends," and then come to this screen:
The only reason why this page is useful is for adding friends, which is a feature that can be accessed at the top right with the plus sign. Otherwise, whenever you select one of your friends, what I would predict to come up would be an option to send a photo to that person. Instead, it opens a page in your browser app with the person's "Snapchat Profile," which I find to be completely useless. Snapchat seems to have a consistent problem with predictability. I have often found myself sort of lost in the app as well.
Good Design #1: Tumblr App
I think this is a really good design, especially in terms of Learnability of the app. Each function is pretty clearly illustrated, which is good for first users of the app and doesn't require a lot of memorization for well-versed users.
This is the first screen that comes up, which is my dashboard. The icon representing it is a home button, which is a pretty familiar symbol, a predictable one considering it is consistent with the non-app version of Tumblr, and clearly highlighted to show that you are on that part of the app. The next tab is tags, which is indicated by the symbol for a price tag. A small metaphor, but the point comes across, and again, it is consistent with the website.
This layout is really clear, pretty minimalistic, but it gets the point across. You can either search specific tags for specific types of posts, or browse through their suggestions. Next over is the section that represents your own Tumblr "profile." This is indicated by the symbol for a person, with a little lightning bolt next to it to indicate when you have notifications. This lightning bolt is a relatively new feature that they didn't have on previous versions of the app, so it's a nice way to know when someone has liked or reblogged one of your posts.
Finally, there is the option to create a post.
This makes use of a few metaphors for the things you may want to post, but is very clear and consistent with the interface on the main website:
Overall, I find using the app to be a very usable experience.
Good Design #2: My iPhone headphones. A problem I often come across with earbuds is forgetting which bud goes in which ear. If I put the wrong earbud in the wrong ear, they are often uncomfortable or something feels off with my listening experience. The headphones that came with my iPhone have the controls and microphone on the right earbud, something that allows me to know immediately which earbud goes in which ear even if I am fumbling around in the dark or in a rush.
This is something that can be easily learned after one or two interactions with the headphones. It's a very simple interface but an efficient one. Additionally, the buttons that control the music/Siri on your iPhone from the earbuds are pretty consistent with the features on the interface of the iPhone itself. You press and hold the control button on the headphones to access Siri, just as you would press and hold the button on the iPhone itself. You press it briefly, once, in order to pause music, and briefly once again to play it again. To skip a song, you press twice in a row, which is sort of mapped to the icon for skipping a song (two arrows). To go backwards, you press three times, which I find to be a bit of an inconvenience but it is a feature that I use rarely.
