The miniaturization of projection technology recently reached a point where battery powered pico-projectors can be carried in ones pocket. These projectors not only allow for mobile stand-alone devices but also the integration into other devices. These new class of devices allow to create ad-hoc mobile projected displays everywhere. Until today this development is mainly technology driven. While projector phones – smartphones with integrated projector – are available, the fact that they are mainly hand-held devices, present a variety of challenges for application and interaction techniques, for the mobile projected display they provide.In this thesis we enable spatial interaction with mobile projected displays to overcome the current technological driven approaches. We contribute by investigating the following three different directions: Applications exploiting spatial features; Analysis of spatial alignment of mobile projected displays; and Interaction techniques exploiting spatial memory techniques. Through the development and evaluation of applications and interaction techniques that rely on spatial features we exploit the users spatial memory and allow mobile projected displays to become a valuable addition of our current mobile devices.
