We’re really not sure that this one has any weight to it all, but word is buzzing around the Symbian blogosphere in response to an assertion that S60 may be looking to TAT to help it modernize the UI. The rumors began in a forum and so far there hasn’t been much if any evidence to support this theory, but it would certainly be in line with the direction that S60 needs to go. Not that TAT’s Kastor UI is anything overly special, but this would go a long way in showing us that Nokia does in fact know that the look and movement of S60 is a bit antiquated. If the Kastor UI does make it to the S60 platform in one way or another, expect heavy customization as the UI shown in the screenshots above (and in this video) are hardly reminiscent of Nokia’s look or feel at all. It shows a great deal of potential though; Kastor’s smooth movement and focus on movement and transitions would go a great way to modernize the user’s experience with S60. We have heard that a lot of work has been going into this area of the user experience lately, but only time will tell. Note that the video in the post linked below is a mash up of the core Kastor UI and parts of TAT’s customized UI framework called Cascades. It is unclear if the rumor encompasses just Kastor or Cascades as well but we assume since the article makes no mention of Cascades, it was included by mistake.
