This paper describes the design of a programmable barcode scanner (the NutraStick) that aims to revolutionize the way people on any kind of diet shop. The NutraStick uses barcode scanning technology alongside an onboard ingredient/nutritional information database to give feedback (Red or Green light) as to whether a particular food item is suitable or not for a person on a specific diet. Usability engineering protocols were used in the design process including feasibility testing and a user orientated interface design process. The use of this methodology allowed for a user friendly, simple, effective, and innovate design.
