PhoneTouch is a novel technique for integration of mobile phones and interactive surfaces. The technique enables use of phones to select targets on the surface by direct touch, facilitating for instance pick&drop-style transfer of objects between phone and surface. The technique is based on separate detection of phone touch events by the surface, which(More)
Natural forms of interaction have evolved for personal devices that we carry with us (<i>mobiles</i>) as well as for shared interactive displays around us (<i>surfaces</i>) but interaction across the two remains cumbersome in practice. We propose a novel cross-device interaction style for mobiles and surfaces that uses the mobile for tangible input on the(More)
HandsDown is a novel technique for user identification on interactive surfaces. It enables users to access personal data on a shared surface, to associate objects with their identity, and to fluidly customize appearance, content, or functionality of the user interface. To identify, users put down their hand flat on the surface. HandsDown is based on hand(More)
Multi-touch interaction with computationally enhanced surfaces has received considerable attention in recent years. Hardware implementations of multitouch interaction such as Frustrated Total Internal Reflection (FTIR) and Diffused Illumination (DI) have allowed for the low cost development of surfaces. Although many of these technologies and associated(More)
Previous work has validated the eyes and mobile input as a viable approach for pointing at, and selecting out of reach objects. This work presents Eye Pull, Eye Push, a novel interaction concept for content transfer between public and personal devices using gaze and touch. We present three techniques that enable this interaction: Eye Cut & Paste, Eye Drag &(More)
We explore how to track people and furniture based on a high-resolution pressure-sensitive floor. Gravity pushes people and objects against the floor, causing them to leave imprints of pressure distributions across the surface. While the sensor is limited to sensing direct contact with the surface, we can sometimes conclude what takes place above the(More)
One of the most popular scenarios for advertising interactive surfaces in the home is their support for solving co-located collaborative tasks. Examples include joint planning of events (e.g., holidays) or deciding on a shared purchase (e.g., a present for a common friend). However, this usually implies that all interactions with information happen on the(More)
Today's environments are populated with a growing number of electric devices which come in diverse form factors and provide a plethora of functions. However, rich interaction with these devices can become challenging if they need be controlled from a distance, or are too small to accommodate user interfaces on their own. In this work, we explore(More)
IdLenses is a novel interaction concept to realize user-aware interfaces on shared surfaces. Users summon virtual lenses which allow for personalized input and output. The ability to create a lens instantaneously anywhere on the surface, and to move it around freely, enables users to fluidly control which part of their input is identifiable, and which shall(More)
