(Abstract from their accompanying paper) BullsEye improves the precision of optical fiducial tracking on tangible tabletops to sub-pixel accuracy down to a tenth of a pixel. Techniques include a fiducial design for GPU based tracking, calibration of light that allows for computation on a greyscale image, and an automated technique for optical distortion compensation.

Multiple users simultaneously interacting with the shared content by panning or zooming on a tabletop often lead to conflicts due to interference. We present ClothLens, a technique allowing for simultaneous interaction of multiple users with shared digital content. ClothLens utilizes the Focus+Context pattern enabling users to create personal lenses on top of the map. The map is organized as a physical cloth object that can be bend or stretched.

The ComforTable is an all-in-one interactive tabletop system with integrated seats and a camera based user tracking system. It allows groups of users relaxed interactions with the interface and was designed for and tested in museums and exhibitions. Applications allow competitive play for up to six players. The tracking system tracks tabletop users to offer them information in their proximity.

We demonstrate CubeQuery, a tangible user interface providing a physical way to both create and manipulate basic database queries. This interactive installation is designed for individual faceted browsing and allows users to explore contents of a music library by physically arranging tangibles on an interactive tabletop.

We demonstrate HuddleLamp, a desk lamp with an integrated RGB-D camera that tracks movements and positions of mobile displays on a table. HuddleLamp's hybrid sensing combines RGB and depth input for tracking movements of multiple mobile screens with sub-centimetre precision by exploiting their optical characteristics in RGB and IR range.

Presents a tabletop system that simultaneously projects output and scans users' fingerprints on the same surface. A GPU pipeline extracts fingerprint features in real-time for user authentication.

By their deformable screen-materials elastic displays and projection screens provide physical three-dimensional interaction modalities like push, pull or bend. Compared with conventional Multi-Touch displays they offer an additional interaction dimension which can be used to explore data. Novel techniques and tools are presented to interact with layered data sets.

Quest - UbiquX fuses a multimodal mixed reality implementation of a traditional tabletop role-play game with a location-based mobile aspect to provide a novel Ubiquitous gaming eXperience (UbiquX).

We present a prototype on touch-enabled magic lenses where each generic lens can be manipulated and parametrized. For activation of different lens functions and parameter setting, we suggest both a widget-based approach for novice users and continuous gestures for experts in one coherent tool.

NEMOSHELL is the windowing system for concurrent applications on multi-user interactive surfaces, which is designed to support multiple simultaneous applications, legacy input devices, legacy applications, and dynamic user interfaces.

(Abstract from their accompanying paper) NetBoards are situated displays designed to fulfil and augment the role of non-digital personal noticeboards in the workplace. By replacing these with large, networked,touch-enabled displays, we replicate the existing physical systems' flexibility and ease-of-use, while enabling more expressive content creation techniques and remote connectivity.

(Abstract from their accompanying paper) We propose P.I.A.N.O., a piano learning system with interactive projection that facilitates a fast learning process. Note information in form of an enhanced piano roll notation is directly projected onto the instrument and allows mapping of notes to piano keys without prior sight-reading skills. We report the results of two user studies, which show that P.I.A.N.O. supports faster learning.

Large-scale interactive surfaces have not yet made the transition from the lab to everyday life. We explore 3 potential scenarios for an interactive dining table in the home: augmented board games, ambient notifications and augmented dining.

(Abstract from their accompanying paper) This paper describes a study that has been conducted to evaluate selected fun.tast.tisch. (a tabletop system for neuro-rehabilitation) modules. The target group usually involves patients (most of them incurred acquired brain injury) and therapists. The study described here focuses on the usability of the system from therapists’ point of view.
