Collaborative Visual Programming Workspace for Blockly

The increasing need for programming tasks performed by non-programmers has resulted in various end-user development tools. In this context, visual programming is currently the prevalent paradigm. However, comprehensive collaboration facilities are missing, although necessary, especially in the domains such as teaching and learning. In this paper, we present an integrated workspace supporting collaborative visual programming. Our system allows end-users to easily cooperate on shared visual programming projects. Peer roles, access and edit privileges for project items are supported. Additional features include: personal project items, toggling live syncing during editing and viewing peer action history. Finally, the workspace’s supported collaboration models are discussed.
