Editor's Notes
- #3 User experience is more than “looks”. User experience represents the overall interaction process of the user with an object. This interaction provides the user with an added value benefit. In this case the benefit that both tools offer is “opening a can”. However it is evident that the can opener will provide the user with a better overall user experience on obtaining the benefit. It is more secure, easier to use and can achieve the benefit faster than the knife. Let’s take this example even further. What is the difference between 2 cars - a 10K car and a 40K BMW? Both take you from point A to point B. There’s a world of difference. For one, the BMW has a much superior user experience (styling, handling, performance, etc.) In addition, notice that a BMW offers its owners an emotional connection, a “pride of ownership.” This gives BMW a unique brand in the eyes of its owners, and to the millions of potential owners who dream of buying this car some day! This shows us that user experience has tremendous business value – ability to differentiate products, create brand awareness, and customer satisfaction.
- #4 We say earlier how user experience is so common-place in consumer goods. Yet, when it comes to software, we are happy to live with “good enough” experiences. When was the last time you had a very satisfying experience with your software, where you thought to yourself “I Love my Software.” Is this because user experience in software does NOT matter? Microsoft firmly believes that user experience in software does matter. Even with our own products, such as Windows Vista and Microsoft Office 2007, Microsoft is delivering software with amazing user experience. User Experience (UX) matters because it helps end-users use products in an easy way (easy to use, relevant, secure, etc.). The things that make a software have a good UX is richness, data viz, globalization, accessibility, etc. UX can be easily measured based on success of usage, productivity, retention, comprehension, and so on.
- #5 In 2001, we introduced .NET Framework. In Nov 2005, we released .NET Framework 2.0. Yet, there was a need to offer our customers additional functionality, such as better user experience in software and workflow. With Windows Vista, we are introducing Microsoft® .NET Framework 3.0 (formerly named WinFX). .NET Framework 3.0 builds upon .NET Framework 2.0, with additional capabilities, such as Windows Presentation Foundation (WPF), Windows Communication Foundation (WCF), Windows Workflow Foundation (WF), and “Infocard.”
- #6 Windows Presentation Foundation (WPF) is a productive, unified approach to UI, Media, and Documents that you can use to deliver unmatched user experiences to your customers.
- #7 If user experience matters, design matters. If design matters, designers matter. If designers matter, we need to make designers first class citizens of the traditional software development process. Let’s talk about how Microsoft is unlocking Developer and Designer collaboration and is empowering them to create successful UX software applications. 1) Traditionally designers would “mockup” the graphic design for a software application. Then by any means possible designers would deliver this “looks” to the developer… they would use JPG images, PNGs, PSDs or even Powerpoint presentations to express the designer intention. Then the developer would receive this “static images” and would try to convert that into reality. If the designer created some “non standard” controls, the developer was forced to code in GDI+ or other complex technologies to create the control raising the time and budget to such level that it was simply better to take the decision of making the UI more “standard”. The developer trying to recreate the idea of the designer would deliver something like what is shown on the right side of the screen. As you can see it represents only a tiny bit of the original vision. 2) In order to enable the collaboration between developers and designers, Microsoft has created XAML. XAML is the format which integrates the development process and is the way for both developers and designers to access the functionalities of WPF. As you can see we have no middle man anymore. XAML is generated by the designer, XAML is consumed by the developer. Further more, the workflow is now two-way meaning that the development process can also start from the developer side who creates XAML and then delivers this XAML to the designer which can take it and style it or completely redesign its appearance. 3) As a brief sample this are the tools that enable this kind of process: On the designer side we have Expression and on the Developer side we have Visual Studio.
