We propose to use them as 'light beams': Everyday objects sojourning in a beam are turned into dedicated projection surfaces and tangible interaction devices. While this has been explored for large projectors, the affordances of pico projectors are fundamentally different they have a very small and strictly limited projection ray and can be carried around in a nomadic way during the day. Thus it is unclear how this could be actually leveraged for tangible interaction with physical, real world objects. We have investigated this in an exploratory field study and contribute the results. Based upon these, we present exemplary interaction techniques and early user feedback. Acknowledgements The authors are grateful to Faheem Nadeem and Fawaz Amjad Malik for their help.
