I'm trying to evaluate options of identifying real world objects. We are creating a product that need to write data and read data based on the object. This would be a consumer product.
Some researched options are:
- barcode (loses some of it's magic if you have to scan a visual bar code)
- iButtons by Dallas Semiconductor (I think these are pretty costly)
What are some other ones that are out there?
- computer vision is way out there in terms of difficulty and cost
The scanning/identification would be up close...a few centimeters.
This would be a consumer handheld device. The objects would be common household objects that can be identified with whatever technology we use...RFID, QR Code, etc. At this point I'm not ruling out touch, but iButtons are expensive.
The MSRP of the reader with some user applied tags should be ~$30 (so if we're using QR codes, we could have them printout QR stickers...if we're using RFID, then the cost of the RFID stickers would need to be considered)
It should be fairly accurate b/c we want a good user experience. We don't the user to be frustrated.
