Re: Use cases for web based signage.

Hi Gisung,

I'm sorry for this late reply.
I couldn't add your proposals to the document easily.

> 1. Displaying different contents according to a distance between a signage and users. 
> 2. Placing contents and buttons with considering the physical aspects of users

It sounds like a guideline for designing contents something.
I couldn't infer any requirements from these proposals.

> 3. Changing color of contents or brightness of screen depending on the ambient illumination around the signage.

Regarding brightness of screen, it sounds like a matter of a hardware.
Regarding color of contents, I don't think that color is not important.
I think that contrast of color is more important in the context.
Even if so, it is a matter of a hardware, not of web technologies.
How do you think?

> 4. Using multi-screen effects - Partial migration of web contents from signage to mobile phone.

As you mentioned in your proposals, R9 covers it.

If your proposals imply any requirements, let me know in form of the format of the document.

* Title,
* Use cases,
* Motivation,
* Gap analysis (not required)

Best regards,
Futomi
