This proposal aims to create a common user profile format to offer personalized service to people with different range of abilities. The common user profile will be device and application independent and adapt user interface parameters like font size, colour contrast, audio volume, arrangement of screen elements and so on. The user profile will store both preference and range of abilities of users and will be able to store contextual information as well. The work intends to follow up earlier similar work at EU standardization committee on user modelling, ITU FG AVA and presently Q11/9 of ITU SG9 and Q26 of ITU SG 16.
