Precise alignment of graphical objects and the creation of accurate layouts are crucial activities in many applications, such as graphics design tools, presentation software or graph editors. Surface computing is very promising for these application domains but not fully explored yet. In this paper we contribute two tools which support layout tasks on interactive displays: interactive grids and multi-touch alignment guides. Both tools allow the precise positioning of graphical objects in a flexible and fluent way by multi-touch input. Direct bimanual interaction and physical metaphors are applied to arrange objects along straight lines and curves. A formative user evaluation showed promising results with regard to a productive and easy use of the tools. Copyright 2011 ACM.

The emergence of mobile and personal projection devices promises new ways to display and interact with content while the user is mobile, and offer new opportunities and challenges for HCI. This workshop1 aims to formulate fundamental research questions around this emerging field and provides a venue for discussion for researchers and practitioners working in this area. We will focus on new interaction techniques, applications, personal projection devices, interaction design, multiuser aspects, multi-modal userinterfaces and social implications. Our aim is to foster the evolution of a mobile and personal projection community.

Creating and editing large graphs and node-link diagrams are crucial activities in many application areas. For them, we consider multi-touch and pen input on interactive surfaces as very promising. This fundamental work presents a user study investigating how people edit node-link diagrams on an interactive tabletop. The study covers a set of basic operations, such as creating, moving, and deleting diagram elements. Participants were asked to perform spontaneous gestures for 14 given tasks. They could interact in three different ways: using one hand, both hands, as well as pen and hand together. The subjects' activities were observed and recorded in various ways, analyzed and enriched with think-aloud data. As a result, we contribute a user-elicited collection of touch and pen gestures for editing node-link diagrams. The study provides valuable insight how people would interact on interactive surfaces for this as well as other tabletop domains.

In order to improve the three-dimensional (3D) exploration of virtual spaces above a tabletop, we developed a set of navigation techniques using a handheld magic lens. These techniques allow for an intuitive interaction with two-dimensional and 3D information spaces, for which we contribute a classification into volumetric, layered, zoomable, and temporal spaces. The proposed PaperLens system uses a tracked sheet of paper to navigate these spaces with regard to the Z-dimension (height above the tabletop). A formative user study provided valuable feedback for the improvement of the PaperLens system with respect to layer interaction and navigation. In particular, the problem of keeping the focus on selected layers was addressed. We also propose additional vertical displays in order to provide further contextual clues.
