The pen servo only controls the | _up_ part of the vertical axis, gravity controls the down. What | I mean to say is that the pen carriage just slides down, it is | not pulled down. | | To solve for that we used... rubberbands. It adds a little | extra downward force to ensure the ink flows. | Animats wrote: | The Autopen AF is a commercial product for this.[1] There's also | MAXWriter and RealPen.

Glad you liked that one. | | So it does introduce random variation. I had the employee write | each letter ~15 times, and then they are plucked at random and | then more "wobble" is applied randomly. So each character is | slightly altered from what she wrote. Her original stroke | actually never shows up anywhere, which is kinda funny to think | about. | | Letter spacing, word spacing, line spacing (y pos), line | starting point (xpos), and baseline drift are all random as | well. | | I don't know how to write and or use a GAN model so I didn't. | Maybe next time! | ipsum2 wrote: | What were the letters for?

OP here. Great question. | | So I think one piece of context that's missing from all of this | is that our service 1) helps people and 2) can never cost them | net-negative. | | Our service is a property tax protest firm, where we represent | homeowners in an effort to reduce their home's "appraised | value," and thereby lower their taxes. | | If we succeed, we take a percentage of the _realized_ savings | to the homeowner, and leave them with the lion 's share. If we | fail, they don't pay us anything. There are lots of firms that | charge flat fees regardless of success. Those are the bads guys | in our eyes. | | I look at the handwriting as way to optimize open rates, just | like writing a good subject line. I know that emails that say | "Hey Aaron!" weren't written one-by-one by a well-meaning | intern. Likewise I assume _anything_ I get in the mail is junk. | We just want people to look at ours and think "oh wow they put | some effort into this piece of junk mail." (We don't think | we're junk mail, obviously.) | | Anyone that uses our service will either make money, or they'll | be left in the same spot they were before. | | So I feel pretty great about that! | | > I'll say that if the machine described could be miniaturized | sufficiently | | It started out mini!

I am | familiar with the Dutch appraisal companies, which spam the | shit out of municipalities with automated legal objection | letters, overwhelming the paralegal capacity, and they make | money off of a combination of upfront legal fees (paid not by | the homeowner, but by the municipality, as 'everyone deserves | access to the law' here) and savings on the property taxes. | It's really approaching spam and has blackmail elements, as | if the municipality doesn't respond within a legal timelimit, | there can be fines or moneys awarded on-top. | | All of this is great for the individual owners who use the | service, but terrible for the municipality and thereby for | society. After all, the municipality is now doing a lot of | unnecessary work responding to automated and entirely free | (spamlike) appraisal objections. Of course the municipality's | budget is paid for by the tax payers. So everyone is in the | end paying for this nonsense, in the form of higher tax | rates. | | Not only that, but in the Netherlands it's lead to a system | where the appraisal values are severely distorted downwards, | and compensated with higher property taxes. Instead of taxing | 1% of $1 million market value, they'll simply appraise it at | $600k and set the property tax at 1.6666%. Nobody can | reasonably argue the $1m home is worth less than $600k, so | the municipality is freed from these appraisal spam | companies, and is still raking in the same tax revenue. But | these unnaturally low appraisals are distorting other things | (e.g. the national wealth taxes which are based on these | undervalued municipal appraisals) and it's all not pretty. | | None of this is good for society and I'm pretty disappointed | that we're now seeing tech move further into the field of | spam, even in a physical sense. | manquer wrote: | Customers ( homeowners?) having a potentially risk free/ no | downside transaction shouldn't have any relationship to | whether they are interested in unsolicited mail or should | receive one. | | It is a ultimately zero sum game I would think, if this | improves your open rate in the short term, everyone from | political campaigns to the local deli, will start doing the | same and everyone would stop opening hand written mails, and | yours(and everyone's) open rate will be back to the same, and | we will no longer be able to open by grandmother's Christmas | cards . | aarondf wrote: | > everyone from political campaigns to the local deli, will | start doing the same | | It is definitely a matter of time until this stops working. | From a quick google of "handwritten letters" here's what I | got: | | * https://www.handwrytten.com/ | | * https://www.scribeless.co/ | | * https://roboquill.io/ | | * https://handwrittenmail.com/ | | * https://letterfriend.com/ ___________________________________________________________________ (page generated 2021-09-19 23:00 UTC)
