lossy numbers

number symbols that even with fading are good
  (+6)
(+6)

I wrote a telephone number on my hand. A few hours later the blurred number gave me some puzzlement. Luckily, I deduced the correct digits.

What about 10 very different symbols so that if there is any loss or blur, the numbers are still distinguishable. I thought the symbols might be along the lines of play station symbols or Zenner symbols.

The symbols would have to be simple for quick conversion and as individual as possible.

Baked? , useful ?

PlayStation symbols http://japanesetran...laystation-symbols/
Well, almost - this article is about a set of japanese symbols frequently used to mark things on a scale. The PlayStation has a square instead of a double circle. [jutta, Sep 28 2009]

       Why not get a pen that has 7 different colors available (I used to have one that boasted 6 colors, plus black and a pencil). Assign each color a number for 4-9 and just write the number in dots, and a colored hyphen or backslash for 0-3. In effect, it would look like technicolor Morse Code, but would be pretty smudge proof. [+] because it's a neat idea and I didn't think of the solution until I read this.

       Impractical solution: Prick your hand with needles to cause welts in the shape of Morse Code.

       [21] Nice idea, you could use a phone app to translate the telephone number into colours.
bigsleep, Sep 28 2009
  

       If you had a phone on you, you could enter the number into contacts instead of using a color-based code to write it on your hand.

       coloured pens is a stretch, who carries a multi- barreled pen. Morse would be a pain if the frame got smudged.   

       I was thinking that an algorithm could compute the difference between the simple symbols to measure their individuality. The more individual, the more likely a blur won't make them similar. Of course there will be a level of error that won't help you no matter how individual the characters are.

       Actually, the characters above the numbers on the qwerty keyboard might work well. If 9 was (, zero could not be ). Too similar.   

       Sorry, on 'my' keyboard 1=!, 2=@, 3=#, 4=$, 5=%, 6=^, 7=&, 8=*, 9=(, 0=)

       I think this calls for another WIBNI sub-category. "Wouldn't it be nice if things were slightly different ?" Hey, what's a glyph amongst friends ? [mfd] WIBNITWSD
bigsleep, Sep 28 2009
  

       [bigsleep] I thought "wouldn't it be nice" ideas usually are not practical or not doable. This symbol coding might not catch on, but then it is amazing what does become popular. Text word coding for example.   

       This would probably have limited application. I could have used it for that phone number so not a WIBNITWSB
wjt, Sep 28 2009
  

       [wjt] You're absolutely right that a WIBNI needs a sub-culture qualifier as much as a NIMBY.
bigsleep, Sep 28 2009
  

       with a bit of practice you could use the abc def ghj etc to write words

       //I used to have one that boasted 6 colors, plus black//   

       Holy shit! Who made black no longer a colour? Is it official yet?

       Japanese numbers, pre-Westernisation, do a pretty good job of this, BTW.
UnaBubba, Oct 01 2009
  

       I thought black was just the darkest shade of any possible colour, and so, strictly speaking, is not one in it's own right [UnaBubba]?
kaz, Oct 01 2009
  

       If this could be adjusted so there is no chance of confusing numbers due to different writers even when scribbled or written quickly, not just blurring, this would be a good thing. I once worked on a set of financial books where the prior treasurer wrote their 8s almost exactly how I wrote my 9s. 4 and 8, 7 and 1, and 5 and 6 are also easily confused under different hands.

       Perhaps a mark could be put on each finger: left-most finger (thumb, palms up) means 1 and count up to the right. Some idea is needed to record the correct order...
Ling, Oct 01 2009
  

       Black is 255:255:255 as RGB; or 0:0:0:100 as CMYK. As a PMS (Pantone) ink it's also a colour,   

       Seems like a colour to me.
UnaBubba, Oct 01 2009
  

       All colours are shades. Black just happens to be one of the two extreme shades.   

       [Ling] Maybe crossing toes could be used to indicate order.   

       [UnaBubba] 6,7,9 are a bit close with the cross at the top. Zero is just to complicated.
