If anyone is looking for a new project I have been asked by a group of visually disabled people that I have done somework for to develop a system whereby a partialy sighted person can put preprinted bar coded lables onto items,such as food tins,video tapes etc and then scan the barcode with a barcode wand and have a big bright handheld display show the items name,kat-o-munch or beans and so on.Because the problem they have is have great difficulty seeing small lables.
I am rather tied up with other projects at the moment,and thought it might be a good student project.It needs to be battery powered,handheld,with a big,high contrast display,or maybe instead of a display a sound sample is played for each different bar code read.whatever.
Anyone fancy having a go,the main design goals are cheap to make,easy to use if you cannot see well,battery powered and robust.
