SVG - XML based vector graphics to replace GIFs and PNGs


While doing UI design I faced problems with animated spinners, which I created in GIF format. One problem is I have to place spinning images on top of differently colored tiles, on various colors, which I cannot control. And second is the tiles are scalable, and the animated GIFs should scale as well. But they don't.

These issues though can be addressed by SVG format, which is supported by all major browsers except Internet Explorer (of course). IE doesn't understand animation in SVG.

(Note: if the SVG graphics doesn't work on this page as described, or for any other reason, you can visit a standalone demo page. On that demo page instead of <embed> tag I use <img>, which in the case of simple SVG animation works exactly the same. However to render it properly in Blogger posts I have to use either <embed> or <object> tags.)
Notice rough edges, and scaling quality loss on the last tile:

Well, with one compatibility issue: animation doesn't work in any version of Internet Explorer. Let's see what else we can do with SVG format.




Mouseover (achieved by CSS inside of SVG file)

All the non-animated SVG above are rendered as designed in all major browsers today. There are issues with animation in Firefox and Opera, but workarounds are possible. All css styling and scripting are inside of SVG files. SVG graphics was created in Adobe Illustrator, and then edited in text editor.

Using Trello and Confluence to manage UX design project. Part 2

Image
This is part Two. Part One can be found here . Term definitions. Brainstorming board. Activity board. Let me give you an overview of the items we refer to, deal with, and vetting all days long. Below are my simple definitions. UX Brief – a living document, a single and comprehensive point of reference of the design project. User Story – a short requirement or request from the end user. Later will be converted into task flow performed by this user to reach the goal. Acceptance Criteria – a set of conditions/statements, or a checklist, which defines the user story’s Pass/Fail . Feature – a functional part of the application, which combines several user stories. User stories are written to provide a complete support to this feature in terms of tasks performed by the user, while keeping in mind the user’s goal. Epic – a large logical group of multiple features in complex application. Brainstorm – a collaborative session involving product owners (PMs) and UX designers...

How do I use InVision

Image
Team lead asked me to write what InVision products do I use, how I use them, what are pros and cons. I wrote it today, and really think it will be helpful to share my thoughts with wider audience. So, below is the adaptation of what I provided to the engineering management in one fintech company.  I use InVision to share my hi-fi designs and specs, which I create in Sketch desktop application. This is my primary and every day usage of InVision, and about 90% of all usecases of all InVision products combined.  I sync designs via the plugin in Sketch made by Invision, called Craft .  When they are in InVision, we call those designs prototypes .  It works, but I often experience slowness. Sometimes sync process is failing, and I have to try it again. In Sketch I select one or more artboards, then initiate sync, which sends the artboard to InVision cloud. I have to be logged in Craft plugin with my InVision credentials. Almost every day, especially when I design intens...

Using Trello and Confluence to manage UX design project. Part 1

This is part One. Part Two is here . Introduction. “ Describe your design process ”. It’s a typical interview question for UX designer position. User-centered design process indeed has defined set of steps. In theory. On the practice though, the adherence to these steps depends on many factors, such as communication and execution skills, practical experience, ability to influence people, being leader and influencer, and at what level your organization is a design driven org. So many businesses are not ready to adopt the design practice, and to place the design before the development. Or simply there is not time or budget to go through all steps. Here in Herbalife the UX Design team accepted Norman Nielsen group philosophy:   Empathize – Define –Ideate – Prototype – Test – Implement .  However the   interpretation of the practical tasks can differ dramatically in different organizations. Here what we currently do: Design Thinking and Agile Any project...
