UIQ (formerly known as User Interface Quartz) is a discontinuedsoftware platform based uponSymbian OS, created byUIQ Technology AB. It is agraphical user interface layer that provides additional components to the core operating system, to enable the development offeature-rich mobile phones that are open to expanded capabilities through third-party applications.
UIQ was the result of 'Quartz', a user interface for penPDAs that was one of the three provisional interfaces that were designed bySymbian Ltd. The first three Quartz phones never made it to market, includingPsion's "Odin" in a joint venture withMotorola, which was cancelled in January 2001, causing Psion's shares to deteriorate.[1] Engineers thereafter created a lighter version of the software which was presented in 2002,[2] and first shipped that year withSony Ericsson P800.[3][4]
Sony Ericsson was the mainOEM using the UIQ platform in its products. Motorola also developed some products using UIQ, but abandoned the platform in 2004 in favour ofLinux, along with its stake in Symbian Ltd. In 2007, Motorola returned to UIQ with the launch ofMotorola RIZR Z8.[5]Nokia, which was using the competingSeries 60 (later S60) platform, created one UIQ device called Nokia 6708, which is a rebadgedBenQ P31,[6] and was only released in the Asia-Pacific region.[7][8]
Sony Ericsson bought UIQ Technology in November 2006,[3] and the next year, Motorola bought half of it.[9]
After the creation of theSymbian Foundation and its favouring of S60 as their user interface of choice, UIQ's future was uncertain, as it could no longer develop the software for the Symbian operating system.[10] Many Motorola UIQ devices planned for 2009 were cancelled, includingMotorola Razr3, codenamed "Ruby".[11]
UIQ Technology filed for bankruptcy in January 2009, which effectively ended the UIQ platform.[12] Sony Ericsson moved on toWindows Mobile and the open source Symbian from the Symbian Foundation, whilst Motorola adopted Google'sAndroid software.[13]
UIQ 3.3 was the last version of the platform, based upon Symbian OS v9.3. Developers that developed on the UIQ 3.x platform had a much better story than with previous releases, since all UIQ 3.x phones were served by a single, coreSDK.
Native applications can be written inC++ using the Symbian/UIQSDK. All UIQ-based phones (2.x and 3.x) also supportJava applications.
UIQ phones employ touch screens with a resolution of 208×320 pixels (UIQ 1.x & 2.x) and 240×320 (UIQ 3.x). Depending on the phone, thecolor depth is 12-bit (4096 colors), 16-bit (65536 colors), 18-bit (262144 colors), and 24-bit (16,777,216 colors) on some newer phones.
For developers, the significant items are:
