Touchscreen on Panasonic CF-18

He remembered the knowledge. He remembered feeling his mind as cold as ice and
limitless as the night sky. He remembered being summoned into reluctant
existence at the moment the first creature lived, in the certain knowledge that
he would outlive life until the last being in the universe passed to its
reward, when it would be his job, figuratively speaking, to put the chairs on
the tables and turn all the lights off.
He remembered the loneliness.

To me it appears that the device was not recognised correctly. A 
touchscreen is an absolute pointer device, and here it shows that it is 
recognised as a relative pointer device.
