Understand how to create app.

From the blog post that i post about how Kevin Systrom and their team succeed on creating instagram, he say that before start to create an app they focus on what problem they are trying to solve and for Instagram there are three problem they set to solve.

Beside that, there are a lot of consideration that we need to learn from instagram to create out a successful application. From i let from my class, we learn that User experience and User Interface is very important when doing interactive design such as website, application and even interactive installation. So for this blog i will try to analyse on the interface and the user experience of Instagram.

User Interface(UI) is a set of commands or menus through which user communicate with a program.User Experience(UX) encompasses all aspects of the end-user's interaction with the company, its services, and its products.

1. Friendly
2. Where is the location of the button
3. How to interact with it
4. what are the feedback after interaction
5. feature
6. stability
7. what people feel when using this application  

This are some of the consideration well we are designing an app interface. For Instagram, it use a very simple interface as their app interface design. By placing the button and bottom area so is easier for user to switch from pages to pages. To view the images, user just need to swipe to scroll up and down. To like a image user can choose to press on "heart' shape button or double tap on the image itself. And the comment is locate under the images.
When a user want to search for image or other instagram user. User just need to select the second page to key in at the search engine on the top of the screen to key in the name and search for the image or user.
When taking photo user just need to press the middle button which have a camera icon button to trigger the camera. After that just swipe the screen to scroll and select the filter that user need to use. After that user can choose whether they want to connect to their other social network to share their images.

Basically this is how it work. Very simple and direct. For my understand, the reasons why the interface is simple is because they are trying let the user focus on the images more. If the button is too fancy and complicated it will make the user out on focus and this will make UX no really relevant.

Although smartphones are very common to us, but the interface of an app still an issue for the app designer while they are design an app. Sometime the designer will go to over on the interface design and lose their focus on the problem solving and the user experience which will cause their application to a failure. Make sure button and font are easy to recognize; don't over due on the Graphic, keep it simple.

Besides that, stability and features are also some of the thing the app designer need to be more concern.
Even if an app has a good interface, you don't want it crashing every few seconds. Do some alpha and beta before release it. Test in different system to check is there any other bugs.
Features in the app is also one of the point that attract user. Don't combine everything, just focus something that had connection with the app and it is necessary to put it into the apps. Focus on what is the problem that you are trying to solve like what Kevin Systrom adviced.
