Subject: Re: [RFC] Multi-Touch (MT) support - arbitration or not
Date: Wed, 10 Nov 2010 11:00:05 +0100 [thread overview]
Message-ID: <4CDA6D25.4070501@euromail.se> (raw)
In-Reply-To: <20101110050219.GB29110@barra.bne.redhat.com>
A comment on pixels and resolution:
A pen and a thumb may have different resolution (signal-to-noise ratio), but
there is no reason they cannot be reported on the same scale. In fact, it could
be argued that it is natural for objects on the same surface to be reported in
the coordinate system of the surface.
So, if anything, the resolution is object/sensor dependent, and adding a
possibility to specify resolution per object type would be good. It would also
be good to know the physical dimensions of the surface.
Cheers,
Henrik
