I haven't been on the list in awhile but it doesn't look like anyone has
posted this.

Microsoft researchers built a prototype exploring force sensing technology
for mobile devices that lacked keyboards and had standard, rigid, components
that resist form articulation. This brings it more into the realm of
practicality, as many companies are not going to develop more pliable
casings (and thus more haptic feedback) due to manufacturing and materials
cost.

They hacked a Samsung Q1 UMPC with the standard Phidget analog kit. The
paper does a good job of explaining engineering decisions they made
regarding thresholds, etc.

They essentially swapped keyboard shortcuts and Windows switching functions
with the following input modalities, with some very surprising results when
testing users.

-stretching/compressing
-squeezing/steering
-bending/folding (easiest for users)
-screwing/twisting
