Definition of "change of context" in mobile context

[JJdeGroot]

In the meeting of October 9, the definition of change of context came up.

Major changes that, if made without user awareness, can disorient users who are not able to view the entire page simultaneously.

Changes in context include changes of:

• user agent;
• viewport;
• focus;
• content that changes the meaning of the Web page.

Note
A change of content is not always a change of context. Changes in content, such as an expanding outline, dynamic menu, or a tab control do not necessarily change the context, unless they also change one of the above (e.g., focus).

Example
Opening a new window, moving focus to a different component, going to a new page (including anything that would look to a user as if they had moved to a new page), or significantly re-arranging the content of a page are examples of changes of context.

We need to consider how to define a change of context within mobile applications.
