A free Silverlight-based site from Infragistics helps to improve thinking and conversation about user interfaces User interface (UI) and user experience (UX) designers have a new, free Web tool to use at quince.infragistics.com. Brought to you by the control vendor Infragistics, Quince is a Silverlight-based site that organizes about a hundred common user interface patterns into a highly usable site.The Quince site builds on work by Jenifer Tidwell and others aimed at describing interface and interaction design with a pattern language. Jenifer’s book Designing Interfaces would be a good adjunct to the site, although Quince stands alone quite well.The Quince site lets you explore UI patterns by name, by task: by UI map:and by tags, with a relationship tree:If you sign in (for free) you can discuss Quince, the patterns, your own experience with specific patterns, and suggest improvements to the pattern writeups. The site is live now. Enjoy. Software Development
