Research with retail grocery stores

My research for the eastman project is in the area of grocery markets. I have narrowed my observation down to self check out regesters and how to improve the area around it. My partner and me interviewed the assistant customer service manager Betty Ward who gave me very good information on the problems and complications with the self checkout. She explained that the main problem was space. This is first self checkout that I found that had displays incorporated with it. More could be placed at the top of the regesters with better use of space and placement displays could be placed around the counter area.
