Interactive projected displays are an emerging class of computer interface with the potential to transform interactions with surfaces in physical environments. They distinguish themselves from other visual output technologies, for instance LCD screens, by overlaying content onto the physical world. They can appear, disappear, and reconfigure themselves to suit a range of application scenarios, physical settings, and user needs. These properties have attracted significant academic research interest, yet the surrounding technical challenges and lack of application developer tools limit adoption to those with advanced technical skills. These barriers prevent people with different expertise from engaging, iteratively evaluating deployments, and thus building a strong community understanding of the technology in context. We argue that creating and deploying interactive projected displays should take hours, not weeks. This thesis addresses these difficulties through the construction of a toolkit that effectively facilitates user innovation with interactive projected displays. The toolkit’s design is informed by a review of related work and a series of in-depth research probes that study different application scenarios. These findings result in toolkit requirements that are then integrated into a cohesive design and implementation. This implementation is evaluated to determine its strengths, limitations, and effectiveness at facilitating the development of applied interactive projected displays. The toolkit is released to support users in the real-world and its adoption studied. The findings describe a range of real application scenarios, case studies, and increase academic understanding of applied interactive projected display toolkits. By significantly lowering the complexity, time, and skills required to develop and deploy interactive projected displays, a diverse community of over 2,000 individual users have applied the toolkit to their own projects. Widespread adoption beyond the computer-science academic community will continue to stimulate an exciting new wave of interactive projected display applications that transfer computing functionality into physical spaces.
