Just because something can be done…

…doesn’t mean it should be done.

Disney researchers use passive UHF RFID tags to detect how people interact with objects
The researchers found that with their system, called IDSense, they could simultaneously track 20 objects in a room and infer four classes of movements with 93 percent accuracy. They will present their findings at CHI 2015, the Association for Computing Machinery’s annual Conference on Human Factors in Computing Systems, April 18-23 in Seoul, South Korea.

“An effective means of identifying people’s activities in their homes, schools and workplaces has the potential to enable a wide number of human-computer interaction applications,” Sample said. “Whether it’s reading a book to a child, cooking a meal or fixing a bicycle, the objects that we use both define and reflect the activities we do in our daily lives.”

Extensive research has also shown that by sloshing gasoline around a home’s interior and igniting it, one can observe how occupants interact with doors and windows.

You thought Internet-enabled refrigerators were bad? Now imagine that everything in the refrigerator is live-streaming that data. Now imagine your insurance company upping your premium based on your beer intake rate. Or that your beer bottle spends too much time in close proximity to your car keys.

Any bets on how soon we hear about the deployment in Disney hotel rooms?

-knock knock- “Maid service! Here’s your extra towels.”

“I didn’t ask for more towels.”

“That’s OK, ma’am. Our system detected unusually heavy and extended mattress use followed by a long shower, and all your towels used. So the computer automatically dispatched replacements.


“And you’ll pleased to know that the computer noticed your husband’s room key lingering by the pool, so it text messaged him not to disturb you while the bed was in use.”

    Am I correct that you have experience in making ink If so using oak galls? I am looking for a formula for Arnold’s Writing Fluid, a favorite ink used by late 20th century wring masters. I’d appreciate any information you may have.
    Thank you

      I do an iron/TANNIN ink, but I get the tannin from acorns rather than galls; acorns being easier to find in quantity, and need to leach out the tannin for eating anyway. [grin]

      I’ve written a few articles about making different inks and pigments. They’re no longer online (unless some else archived ’em). I can email you the one specifically about iron/tannin ink, if you like. (You can reach me at carl-=at=-bussjaeger-=dot=-org.)

      I wasn’t familiar with Arnold’s Writing Fluid, but a web search turned up this:

      2485. Arnold’s Writing Fluid. Arnold’s writing fluid is a mixture of sulphate of indigo and ordinary ink. It flows freely from the pen and at last becomes very black. On account of the large quantity of acid it contains, it is very destructive to steel pens, and for this evil we know no cure.

      Based on THIS, I think “sulphate of indigo” is indigo dye mixed with sulphuric acid (battery acid). (The dye link specifies 1 part indigo to 4 parts acid, then 1 part potassium carbonate.)

      You’ll have to flip through that Google book to see what it calls “ordinary ink.”
