“…Whilst the social acceptability of established technologies is well understood, at least tacitly, social acceptability of nascent technologies such as pico projectors is not. Only Cowan et al [2], in a field study on how users might more generally employ pico projectors, considered social factors around projection. They found that the content users would choose to project changed on who the user was with, and provided examples where users chose not to project content based on their situation (e.g.…”

“…Using a body worn Microsoft Kinect 3D camera and pico projector, Harrison et al [7] have developed a system that allows ubiquitous projection and interaction with a touch-based graphical user interface on any physical surface in front of the user. Cowan et al [2] developed a simple sketching program that projected drawings. They found users created interesting interplay between the physical and digital world.…”

Increasing amounts of geo-tagged social media have led to interest in how that media can be re-integrated into the physical environment. Yet, although location information is often automatically appended to media, little is know about how users consider location in its creation and viewing. Using Graffiti as a design meme, we developed a novel social media service to investigate these issues. A two week field study showed how users incorporated both utilitarian and playful aspects of location into their social media creation, as well as revealing a disconnect between the location-media relationship intended by creators and perceived by viewers. We outline implications of our work for services that seek to repurpose existing geo-tagged social media in the design of novel services.

“…Projection using Pico-Projector with a camera and both are embedded in a single mobile device [8,9,37] or we can have a hand-held projector and visual feed back to the system is provided using a wearable device such as Google glass [38], Recon Jet [39] and Telepathy [40], etc. In the latter case both the user and the camera have the same perspective.…”

“…In the projector-phone space, Greaves and Rukzio [10] found that users preferred projector-based interaction over phone-based interaction. Cowan et al documented commodity projector phone use "in the wild" [6], finding that, even without projection-specific input techniques, these devices afforded novel interaction modalities.…”

Pico projectors attached to mobile phones allow users to view phone content using a large display. However, to provide input to projector phones, users have to look at the device, diverting their attention from the projected image. Additionally, other collocated users have no way of interacting with the device.We present ShadowPuppets, a system that supports collocated interaction with mobile projector phones. Shadow-Puppets allows users to cast hand shadows as input to mobile projector phones. Most people understand how to cast hand shadows, which provide an easy input modality. Additionally, they implicitly support collocated usage, as nearby users can cast shadows as input and one user can see and understand another user's hand shadows.We describe the results of three user studies. The first study examines what hand shadows users expect will cause various effects. The second study looks at how users perceive hand shadows, examining what effects they think various hand shadows will cause. Finally, we present qualitative results from a study with our functional prototype and discuss design implications for systems using shadows as input. Our findings suggest that shadow input can provide a natural and intuitive way of interacting with projected interfaces and can support collocated collaboration.
