In one of our previous blog articles we talked about the use of pie menus in touch screen interfaces and discussed pros and cons of this kind of interaction. In this article, we are going to show a concrete example of how a pie menu can be used.

In recent years, so called “natural user interfaces” (NUI) have grown in popularity. More and more often, interaction via touch and gestures is employed instead of using mouse and keyboard. The iPhone was greeted with great enthusiasm and played a major part in spreading touch screen system in the consumer market while also introduced gesture-based interaction in a playful way. There should be hardly any touch screen user who is not familiar with the pinch gesture that is used to resize or zoom images on the iPhone.

Keeping the background information of the previous article in mind, assume you want to make use of Blend to design a NUI based on Silverlight or WPF that lets you easily manipulate items on the screen. In the beginning, you won’t even touch the tool at all – you “invent” whatever gesture you think is intuitive to perform this operation. Most likely you do this in your head or on the whiteboard. You discuss and refine the design with your team mates or with potential users. At this stage everything is still low-fidelity and throwing away things isn’t costly yet. As soon as you have a good-enough feeling about the rough design, you start prototyping with higher fidelity. This is to be really sure your idea works. To provoke the intended interaction experience, caring about every single detail is exceptionally important in later prototyping stages.
Every user interface designer is familiar with the procedure to some extent: To find out what a user interface needs to look and behave like it’s certainly a good idea to create a prototype and evaluate it with potential users. Users will tell you what’s still nagging them and therefore should be improved before coding starts. So, in the beginning of any UI design process everything is about change – you create a prototype and already expect it to require modifications in order to work alright. As you – and most likely your client, too – want changes to be as cost-efficient as possible, you are better off taking a change-friendly prototyping method or tool. This is especially true in early stages of the project your ideas of potential solutions are rather vague. In this early phase, most often you don’t even know the exact problem for which you are in hunt of a solution. You are still analyzing more than you are designing.
As described in January’s post, animations can fulfill essential purposes in user interface design. This article provides some insight into a study that has been conducted with the goal of exploring the effects of animations regarding user experience.

There are a lot of free icon libraries out there, however, only few of them focus mainly on medical icons and we wanted this gap to be closed: we introduce Centigrade’s stock icon library MedicalSeries, containing 60 icons that you can download free of charge.
Red is not always red, green is not always green. For quite a large amount of people it is not easy to distinguish between red and green hues. About 6% of all males have the same difficulties to tell orange from olive-green as unaffected people have to distinguish between burgundy and ruby-red – oftentimes, it is impossible. This most common kind of color vision deficiency is called Deuteranomaly, also known as “green weakness”. The following article will deal with the question of how this wide-spread impairment impacts the production process of high quality icons.
After dealing with general market trends in part 1 of this blog series this second and final part provides a more detailed comparison of Google Android and JavaFX.
Centigrade specializes in creating GUIs, in many projects with a particular focus on the implementation of Java Swing based GUIs for desktop applications. With the advancement of the mobile market, it is an obvious step for Centigrade to also have a look at Java based mobile GUIs. This article gives an overview on the mobile market today and includes a comparison of the two major Java players in that sector, Google Android and JavaFX.

In the previous part I took a closer look at how and to what extent Microsoft Expression Blend and Adobe Flex Builder offer pixel-graphics and vector-graphics tools to enable GUI designers to create modern user interfaces. In addition I outlined the concept of 9-Slice-Scaling, a method to make pixel graphics scalable without any quality loss. In this last part of the series I’m going to give a short example of how the concept is implemented in both tools and finally provide an overall comparison of the two tools to point out their strengths and weaknesses.
The previous part of this series outlined why it is not possible to just create one single vector-based instance of an icon to scale it to any desired size. This part raises the question, on the one hand, what tool support would need to exist in the future in order to serve an icon designer’s everyday work adequately and, on the other hand, what tool support already exists to make his life at least a bit easier in the present times.

In the first part of this series I described how user interface design tools bring together developers and designers in a seamless workflow and gave an overview of the technical environments of Adobe’s and Microsoft’s tools in that area.
In this article, I am going to focus on the use of pixel and vector graphics in design, deal with some of the pros and cons of the two graphic types and finally give an introduction on the scaling of bitmap GUI components.
