Remote collaboration among geographically dis- persed team members has become standard practice for many companies and research teams. A number of computer supported collaborative work systems exist, but there still lacks acceptable support for teams working in creative settings, where tradi- tionally numerous physical and analog tools are used. We have created an environment for teams applying creative methods that allows them to work together efficiently across distances, without having to change their working modes. We present the Tele-Board system, which combines video conferencing with a synchronous transparent whiteboard overlay. This setup enables regionally separated team members to simultaneously manipulate artifacts while seeing each other's gestures and facial expressions. Our system's flexible architecture maximizes hardware independence by supporting a diverse selection of input devices. I. INTRODUCTION Collaborative creative work is done best in co-located settings (12). People directly communicate with each other, see each other's gestures and facial expressions, and manipulate all involved artifacts. Sticky notes, whiteboards, walls, pens, all imaginable prototyping material and methods like role- play or storytelling may all be used when creative methods such as design thinking are applied (2). Furthermore, bringing together the insights of research and different perspectives of a diverse team is a key factor for successfully fueling innovation (30). In order to incorporate different cultural aspects as well, international teams are often favorable. But how can teams reasonably use the above-mentioned analog tools if members are geographically dispersed, and time zones separate them by several hours? Can suitable digital equipment replace these tools to support teams in their usual way of working, regardless of members' locations? A number of tools supporting remote collaboration already exists. In the last years, commercial products for remote collaboration improved tremendously to enable easy video conferencing with various levels of quality and costs. But satisfactory support for distributed creative working does not exist yet. Most tools only support standard desktop tasks and are cumbersome to use (11). Scientific research projects that study how people commu- nicate remotely and share working materials across distances exist for almost twenty years. But remote collaboration en- compasses a variety of different aspects, and these systems have focused on specific use cases. Some concentrate on the role of audio and video (with no whiteboard support) (8), (14), base location A base location B
