SUSTAINER is a container and digital application system, which work together to create more sustainable habits regarding food storage and transportation. food container concept. After consulting with the student union about their system, and talking to people that use the mug wall, it was decided to install five collection points around the university. After consolidat- ing the information gathered from interviews, statistical research, and precedent studies it was apparent that the most efficient solution for Sustainer was to put the onus on the user and develop a support system for them to maintain usage of their own container. SYSTEM DESIGN WITH VIDEO SKETCHING Video sketching is a simple and quick method of rapid prototyping displaying accurate context along with different scenarios of how a user might interact with a product and/or system. Communicating a rich interaction between a user, a product, and a smartphone proved to be nolds mare rey most visited location the noodle box least visited location save-on-foods more difficult than anticipated. Maps, diagrams and other two-dimen- sional communication methods were deployed to try and communicate to instructors, friends and the public how the Sustainer system worked. After getting feedback it was realized that these methods were not getting the ideas across effectively. Video sketching then became the most obvious way to better understand the interactions users would have with the product. This form of rapid prototyping and visualization was fundamental to getting a handle on what elements of the system had holes and which elements seemed flushed out. Video sketching was helpful in showing the context along with how the user would ideally interact with the product and system. It was also extremely versatile as it could easily be shown on a computer, tablet or even phone for quick feedback. INTERACTIVITY we “I
