Sensors are located below toilet seat and feet with
constant readout (eg. 7-segment LCD with solar power).
Once in position to perform one's duties, one simply sits
or
stands still and taps the "trip" meter which marks the
starting weight. After the labor is finished, one sits or
stands
still once again and hits the second "trip" meter
to
mark the finishing weight. The difference in weight is
then displayed.
Various accoutrement can be used to accessorize the
device, such as sound effects to denote certain ranges
of
weigh change. (Ex. if a difference of more than 2 lbs is
achieved, then a carnival bell sound rings. if no
difference
is weigh is achieved, the sound effect from the Wheel of
Fortune's BANKRUPT slice is played.)
Also, a scoreboard should be available, replete with user
initials, date, and score.
NOTE: A special award should be offered in the event
that
the finishing weigh exceeds the staring weigh, such as
having the machine dispense a suppository.
