Call for Review: IndieUI User Context for web interface preferences

Dear WAI Interest Group Participants,

Today we published the First Public Working Draft of the IndieUI: User Context 1.0 – Contextual Information for User Interface Independence technical specification at:


"IndieUI" - Independent User Interface - helps web applications work better with different devices (such as mobile phones and tablets), different assistive technologies (AT), and different user needs. With IndieUI, web application developers will have a uniform way to design applications that work for multiple devices and contexts. IndieUI includes two technical specifications: IndieUI Events and IndieUI User Context.

IndieUI: Events defines a way for different user interactions to be translated into simple events and communicated to web applications. For example, if a user wants to scroll down a page, they might use their finger on a touch screen, or click a scroll bar with a mouse, or use a scroll wheel, or say "scroll down" with a voice command. With IndieUI, these are all sent to the web app as simply: scroll down.

IndieUI: User Context defines a set of preferences that users can choose to expose to web applications, and an API for user agents to access the preferences and listen for changes. Users can set preferences for features such as screen size, font size, and color. Users with disabilities can provide information about assistive technologies in use, indicate that the display is in an accessibility mode, and indicate what kind of subtitles and audio descriptions they need. Web applications can use this information to optimize the presentation without a requirement to target a specific device, operating system, or locale.

Please send comments on the IndieUI: User Context Draft by 1 August 2014 either:
