Ang. Re: [GOK] Why ui grabbing in direct selection mode of gok?

[Mats Lundälv <mats lundalv vgregion se>]

I appreciate the arguments for the ui
grabbing in GOK - both for switch input and direct selection users.

But there are also reasons for wanting
to disable this functionality for some users in some situations - in fact
for some users of both these categories: 
GOK is currently targeted towards advanced
alternative input users. For them the ui grabbing will often make sense,
unless for direct selection users who master the ordinary gui without major
problems.

But for some other potential users,
e.g. individuals with additional cognitive difficulties, it may be preferrable
to have a more stable interface with less functionality. The dynamic features
of the ui grabbing may be disturbing and confusing rather than helpful.

So does it have to be either or? I don't
yet know the inner secrets of GOK well enough, but I would like to have
an easy way to turn ui grabbing on/off - both for a support person and
possible to provide for the user him/herself. Is that possible? If not,
could it be added?

Another aspect that I have found very
awkward is the fact that GOK (and I believe also OnBoard) requires the
adaptive features for the physical keyboard (like sticky keys etc) to be
activated for the OSK to be fully functioning. This is really unfortunate
and weird, as well as totally non-standard for all other OSK solutions
outside the unix-linux sphere: 
Why should the OSK - being provided
for users who cannot use the physical keyboard - be depending on alternative
settings for the physical keyboard? This is a totally unmotivated interference
in the basic system settings, and in fact creates accessibility problems
for people supporting the OSK user. I regard this as being a design flaw
that should be removed asap. Any comments on this?

Cheers,
Mats Lundälv

I'd also add that GOKs OSK to anextent provides an
abstraction and
simplification of the UI and is very consistent. Such limited
interaction  may be of benefit to some people mentally as well as
physically
