Communication with remote persons over a video link is common today, e.g. to connect with family members abroad, particularly during the COVID-19 pandemic. However, social activities such as board games are rarely shared in this way, as common video chat software does not support this scenario well. However, interactive tabletops provide inherent support for natural tangible interaction with items on the tabletop surface.We present the Tabletop Teleporter, a setup designed to merge two remote locations into a single shared interaction space. We evaluate the system using a board game, focusing on the perceived immersion and connectedness of participants. Our evaluation shows that most measures for the social quality of a remotely shared game are not significantly different from one played with co-located participants, and that players prefer our setup over a pure videochat scenario.

We present TouchScope, a hybrid multitouch interface for common off-the-shelf oscilloscopes. Oscilloscopes are a valuable tool for analyzing and debugging electronic circuits, but are also complex scientific instruments. Novices are faced with a seemingly overwhelming array of knobs and buttons, and usually require lengthy training before being able to use these devices productively. TouchScope uses a multitouch tablet in combination with an unmodified off-the-shelf oscilloscope to provide a novice-friendly hybrid interface, combining both the low entry barrier of a touch-based interface and the high degrees of freedom of a conventional button-based interface.

We present TouchScope, a hybrid multitouch interface for common off-the-shelf oscilloscopes. Oscilloscopes are a valuable tool for analyzing and debugging electronic circuits, but are also complex scientific instruments. Novices are faced with a seemingly overwhelming array of knobs and buttons, and usually require lengthy training before being able to use these devices productively. In this paper, we present our implementation of TouchScope which uses a multitouch tablet in combination with an unmodified off-the-shelf oscilloscope to provide a novice-friendly hybrid interface, combining both the low entry barrier of a touch-based interface and the high degrees of freedom of a conventional button-based interface. Our evaluation with 29 inexperienced participants shows a comparable performance to traditional learning materials as well as a significantly higher level of perceived usability.
