I am looking for someone to walk around a major brand retail store in for approximately 4 to 5 hours with a smartphone app enabled to collect data for an indoor positioning system. Smartphones with the app pre-loaded will be mailed to the store in advance. You will pick them up from the manager on duty upon arrival. Detailed (video based) job instructions will be provided, but the primary skills required are the ability to read a store map and use a basic phone app. Travel time will be paid at the regular hourly rate.
