RE: Next step for DAP Ambient Light Events

A quick un-scientific test:

                                    Nexus 7 tablet (JB)       Galaxy Nexus Phone (ICS)                  Xolo Phone (ICS)

Office lighting:           ~550 lux                                    ~170                                                 ~700

Flash light (1"):          ~40,000                                   ~12000                                             ~48,000


Thanks

I am not sure I follow what your worry is.  Suppose we have a sensor who's range is only inside one of the defined 'types'.  Implementation would still fire change notifications when the lux value changes.

My thoughts:

Ambient light sensors have different range in lux depending on the manufacture and type of use.  I don't know if it makes sense to map these values into "type".

Just a couple data point from googling..:

We might consider exposing a string 'type' to the light event that matches what was outlined by [1].  I think I would be okay with that as so long as it was an optional field of the event.

Thoughts?

Maybe this is more on the CSS WG side with help from your WG.
We could start discussing that for our next level of Media Queries and have you involved to be sure it's consistent with the API.
I'm not sure we need a joint effort here. What you think? Doug?
