RE: ISSUE-6: User Interface Issues for Mobile Browsing

Thanks Luis. This is obviously much more useful and comprehensive than the 
brief editor's note suggested when the issue was first opened. 

What do you think is the best way to incorporate this into wsc-usecases? 
In other words, now's the time to propose the literal, concrete change. My 
first thought is that 10.1, which currently discusses public review 
expertise, can be extended to include participant expertise, and have a 
pointer to this stating participant expertise in mobile browsing. I could 
also see a section on the Applicability section of our proposal template, 
and how mobile modalities is one being considered (either with all this 
text or a pointer to it). Luis, how do you think this should be 
incorporated in wsc-usecases? Tyler, as editor, other better thoughts?

RE: ISSUE-6: User Interface Issues for Mobile Browsing






Hej,
 
>> I don't quite understand what "state" means ... I imagine "context" is 
...
 
User's state means predispositions, expectations, needs, motivation, mood, 
etc. Context is not only physical (like the ones you mentioned), but also 
social (people surrounding the user), temporal (how long time a user has 
for browsing) and task (what the user is trying to achieve). All these 
impact mobile browsing.
 
>> isn't there some chrome? 
 
I meant the visible part of the chrome. There is still the possibility of 
controlling the browser via button clicks.
 
>> I don't understand the "T9 feature". 
It's a predictive text (faster typing) technology (Text-on-9-keys) due to 
lack of a complete keyboard.
 
Attached is a revisited version where I have considered your comments and 
re-written some unclear part of the previous (inline) contribution.
 
Luis

I don't quite understand what "state" means. Can you give an explanation 
or some examples? I imagine "context" is the user's physical context - 
noisy, quiet, moving, walking, lots of light, home, work, etc.

Given that "Chrome" is the entire control surface of the application:
http://www.w3.org/2006/WSC/wiki/Glossary

isn't there some chrome? If not menus, then dialogs? There must be 
something that communicates "control" information.

Good that they don't display favicons :-). Plus there's seems to be a lot 
of problems with relying on the "raw" URL for security anyway.

I don't understand the "T9 feature".

Please point us to the results when the time comes.
