I am doing research for a college project on mobile devices, and have decided to design a device specifically for diabetics that logs information gained from blood samples and provides a graph and average (and maybe some other features...undecided as further research will inform the features of the device) so that levels can be monitored and taken to a doctor during checkups to provide a more accurate picture of the state of the user's condition. Do you think there is a need for something like this? would it be helpful to doctors and diabetics? do you have any suggestions? would there be any merit in a device designed for children to use?
