About: pen friend voice labeling system from speak to me catalog
While perusing the Speaktomecatalog for a cholesterol monitor which measured both LDL & HDL as well as triglycerides I ran into your voice labeler. I thought it might be reading some coded barcode off of the label itself. When I found out it was not, I thought that manufacturers could provide one with very little extra added effort. Something which provides critical information . Otherwise you need someone else to read labels for you if your are blind.
- blind labels
You could also have a pen which could extend the info by bringing up a specific url at the computer for those who have one.
Yeah the pen friend reads a bar code, but it has to be the ones they put on the labels they give you. But there is an app for what u describe above on pod-pads.
