We present MoCoShoP, a system that supports the collaborative process of shopping and planning furniture and interior items. The system consists of a mobile application running on the users’ mobile phones and an interactive surface application deployed on shared planning desks in the furniture retail store environment. Users belonging together share a virtual shopping cart. By scanning labels attached to furniture items with their phones that are of interest, users can inspect item details (e.g., dimensions, available colors) with the mobile application and add items to their shopping cart. The shared planning desk allows users to collaboratively review collected items and create possible arrangements of items on a floor plan. Finally, users can store furniture arrangements for later inspection. In this work, we contribute the design and a prototype implementation of MoCoShoP. Results of a first evaluation indicate that users appreciate how they can collect and share data during the process of shopping and how it supports collaborative planning.
