The two features described above are the only features that are ''necessary'' for the consumer's terminal. In the following I describe a few additional hardware features, which would enhance the usability of the system. | The two features described above are the only features that are ''necessary'' for the consumer's terminal.

The phones are fitted with VGA resolution cameras. The focusing and resolution properties of the phones were maybe just a little bit too poor that one could use the pictures to OCR the numerical representation of EAN-codes. But it came very close, so hopes are high that OCRing the code will be possible in the near future. OCR could alternatively be done from shelf tags, which usually contain the product name in a fairly big font with uniform typeface. Also using image recognition of the packaging graphics is being considered. | ||
*The phone could have a bar-code or a general purpose scanner. This would be a perfect hardware feature for Consumerium usability. It would boost the speed and precision of using Consumerium, but unfortunatelly it doesn't seem one of the likeliest gadgets to be integrated into a mobile phone. I've been in contact with Nokia about this feature and I got information that Nokia and other phone-manufacturers have researched the feasibility of integrating a bar-code scanner. At the moment I don't have knowledge of anything concretic happening in this area, but hey, who knows? | *The phone could have a bar-code or a general purpose scanner.
