The coin is placed into a small plastic rectangle, I align it to the right edge, approximately the same distance from the three sides of the rectangle.
I use a little phone stand to keep the phone levelled, approximately two inches above the coin. These are definitely not good quality, but it serves the purpose. The picture was more difficult, but I found a relatively easy way of taking a recognizable picture of coins. But when I made the questions more specific, such as what is the country, value, currency and date, I started getting excellent responses. I’m stating the obvious here, but asking what kind of coin it is doesn’t get the right answer, at least not the one I’m looking for. It definitely took a while to figure out what works best. How do I get coins posted for recognition? Therefore, I get a much more accurate response. The pictures go to many volunteers, and only those people respond who can help with the answer, or interested in finding it out. First, I post the picture, and only those people respond who exactly know what I’m looking for, and can read the coins. I use these solutions for other things, such as setting the AC in a hotel room when I’m alone, matching shirts with pants, reading a screen when my screen reader freezes, etc. Of course, I can explain, but it can be very time consuming, and I found the results very minimal, as coin recognition requires somewhat of a specialized knowledge. I tried those solutions as well, when I’m recognizing coins, the results really depend on how familiar people are with coins or what exactly I’m looking for on them. There are other services, where I can contact a real person using my phone’s camera, and ask for a description of anything. It may give me a little more info about US coins, but not enough. In case of coins, the recognition is very poor, for most foreign coin all I get is “silver coin”. There are apps which use image recognition to analyze what is on the picture. I won’t list them here, but they are all great. There are many similar applications trying to achieve the same thing, approaching it from different angles. In a nutshell, I can take a picture, ask a question about it, send it to volunteers, and whoever is available and is willing, can describe the picture, either using text or voice, and I receive the response, usually within seconds or minutes.
#HOLY GRAIL OF AMERICAN COINS ANDROID#
It is not a coin identifier app, but it is the closest I can get to one.īespecular is an iPhone or Android app, using crowd sourcing to help blind people identify anything they take a picture of. While this hasn’t changed, I found a solution where I don’t have to bug friends and family, and I can get a coin recognized any time I’d like to. There are a number of shortcuts, but in most cases I need help from a human. I was trying to come up with all kinds of ways of using technology to do this independently, but I couldn’t succeed. There just isn’t a good way to do it alone. Those of you who have been reading this blog for a while probably know that the biggest challenge of collecting without vision is recognizing an unknown coin. This post is only slightly related, but I wrote a new one. When people are looking for coin identifier apps, often they end up on this page.
