psion like keyboard discussion

[undo]

I ask to pinehone chat and the mic is positioned on bottom, near usb port, so there is no problem with mic.
And it is possible to use loudspeaker if the volume is not enough with phone closed.
It also possible to use bluetooth or jack headphone (both with mic included).
And maybe it'is possible to resolve problem of information through software remapping volume keys when keyboard is closed to speak some information (with robotic espeak ).

But I also think that it is very useful if the keyboard communicates the opening status to the phone, this status can be used to change notifications when the keyboard is closed and automatically turn on/off the screen when it is opened/closed. You could also automatically answer calls when it is opened or in any case all configurable events if you have this information.

But if the keyboard doesn't have this trigger, I think you could derive this information less precisely by logically operating on (the presence of an attached keyboard) and (the proximity sensor)

Thanks, good info. I wonder though, from a user experience perspective, if it would make sense to have the proximity trigger standby. Because, this would mean that you cannot anymore open the lid and talk to the phone (It would think your face is the keyboard and go on standby). But to me it seems that this is exactly the most "natural" user experience when answering a phone; You hear it ringing, you open it, you talk to it. So, in case there is no lcd display but there is the proximity triggered standby, the sequence would be: Hear it ringing, open it to see who it is, close it and press a button. This is a crazy way to answer a phone

EDIT: I realized, the above is not a problem, since the phone would not stop the call or the mic input or anything when the keyboard is closed. But are there other, similar problems derived from the keyboard needing the proximity sensor to know the closed state?
