My original trackball design is practical and cheap to implement
not 100% sterile. For the total germophobe crowd you could install
series of raised pairs of nibs housing electric eyes - each beam
to a floor. Simply break the beam for your desired floor and there
no touching involved and your elevator ride is perfectly sterile
except for the coughs, sneezes and other noxious emissions
by your fellow passengers of course.
I considered a gesture based system a la MS Kinect but figured
would be too much potential for nonfunctionality for people like
[Alterother]'s hillbillies or for those whose range of motion was
restricted through disability or just an armload of packages.
capable of using current lift buttons should be able to break the
beam of an electric eye.
If you put the floor number label behind the beam even the
passenger would unwittingly succeed in operating the lift by
touching the label of their desired floor with their filthy,
pestilence-ridden fingers. The rest of us would just swoosh our
fingers through clean-ish air.
I would suggest having
pairs of nibs separated and offset a bit so punters don't activate
multiple floors inadvertently (or on purpose).
||It's nice to know that I'm not the only one who spells it germophobe.
Could be a Canadian thing.
||Don't germophobes carry tissues and disinfectant with them
everywhere? I've only ever met one that I know of, and she
just wore gloves and sanitized things before she touched
||Pity Howard Hughes is dead -- he'd have bought
these in quantity.
||HPV vaccine by lift control, i think. A bit like pelvic
floor exercises in a very limited way.
