The iPotty

I know what you are thinking.
You are rolling your eyes and imagining that I am going to fill this space with juvenile potty humor.
This just goes to show how narrow minded YOU are.
Actually I am going to fill this space with sophisticated, adult potty humor.
In many countries when you go to the toilet, you can expect to find one basic model everywhere. In the US, for example, the "American Standard" is common – both in private dwellings and in public restrooms.
As I have written before, Japan has started a revolution in toilets. Despite this, however, when you go to a public restroom, you never know just what point on the toilet evolutionary scale you will encounter. It could be an old fashioned "squat pot", a simple Western-style toilet, or a fancy washing toilet with all the "bells and whistles". It's better than the old days when public facilities often did not have any toilet paper, but you still go through emotional ups and downs, walking to the restroom, anticipating one thing but finding another.
Although the range of toilets is greater in public restrooms, you can still be surprised at private homes. A visit to a friend's house provided just that sort of experience. A fairly wealthy family, they had recently installed a top-of-the-line appliance in their downstairs restroom.
I walked into the small room (only a toilet and a tiny sink) and was surprised by the top lid springing open – a gaping mouth ready to take a bite out of me! The toilet left the seat part of the toilet down, however, not being smart enough to determine that I was a guy and why I was in there. I had to raise the seat by hand, but it didn't seem to like me doing that (I found out later that there is a button for that function) and fought with me over raising the seat. Perhaps it was questioning my gender.
I finished what I came into the restroom to do and politely closed the seat and the lid. The toilet automatically flushed itself. I turned to the sink to wash my hands, and I must have moved my arms too much, because the toilet lid sprang open again, staring malevolently at me with its built-in LED light. I quickly closed it, and the appliance fastidiously flushed again.
The next morning, I needed to use the toilet for a more "significant" purpose. The lid jumped open as I entered the room, but I didn't need to fight with the toilet to raise the seat.
I sat down, completed my mission, and glanced at the control panel on the wall next to me. This is called a "stick remote control". Please have a look at the link above, so you can see how confounding a control it is. The large round buttons on the vertical portion of the controller are from left to right:
               Butt             Bidet
OFF                                                      Water Pressure     Washing Position         Clean
               Soft        Wide Bidet                                                                                Nozzle

The row of nine smaller buttons on the top of the controller are from left to right:
Big   Small   Eco Small    Move     Massage     Power Smell Removal     Dry  

and

Open Lid    Open Lid & Seat

Where do I start?
First of all, if you live in Japan, very quickly you learn that BIG and SMALL on the toilet flush-lever does not mean you need to gauge the size of your deposit and flush accordingly.
"Well, I DID have three burritos for dinner last night .... so.... big?"
No.
In Japanese "small" is "number 1" and "big" is "number 2", so that function on the remote was fairly clear. Eco Small probably means you would use less water. What I was worried about was "Move" and "Massage". The positioning of the washing nozzle is set by the large buttons on the front of the panel, so what would I be moving if I pressed the MOVE button? Might the whole toilet take me into another room? Or perhaps it was some sort of enema function that would "move" me in a different way. In any case, I wasn't going to experiment.
Also the button with BUTT on the top and SOFT on the bottom left me anxious. Controls with ranges of function usually have contrasting labels: High and Low, Strong and Weak, Front and Back. The contrast of BUTT and SOFT didn't seem to have anything to do with the human body.
And what about the MASSAGE button? I really wanted to know exactly what part of my anatomy the toilet was going to massage before I pushed it.
The toilets I am accustomed to have only basic wash functions, so I restricted my cleaning efforts to those. I stood up, closed the lid, and the toilet dutifully flushed for me.
Once again, while I was washing my hands, the lid snapped open as if to say, "Did you finish your business? Are you SURE?!"
I closed it and as I left the room, I could hear it fussily flushing itself again.
The technology has gotten increasingly complex. Early washing toilets had only a wash and a bidet function (I have NO idea why you would need both, but I have a very limited imagination). These have evolved into toilets which do things for you that you didn't know you needed done. The future obviously will bring even better facilities, perhaps with richer interactive functions that we can program like cars to "read" us as individuals and do unto us as we would do unto ourselves in many different ways, while treating other people completely differently.
Talk about a brave new world.....
