We present 3D-Board, a digital whiteboard capable of capturing life-sized virtual embodiments of geographically distributed users. When using large-scale screens for remote collaboration, awareness for the distributed users’ gestures and actions is of particular importance. Our work adds to the literature on remote collaborative workspaces, it facilitates intuitive remote collaboration on large scale interactive whiteboards…
ERiC Emergency Response and information Center Situation awareness is essential to the decision making process in the emergency response and control setting. Incorrect, distorted or incomplete situation awareness can lead to erroneous decisions with catastrophic consequences. Situation maps used for planning and decision making are fundamental to correct and complete situation awareness, and the maps…
In practice, most creativity techniques are still performed with traditional tools, such as pen and paper, whiteboards, and flipcharts. When transforming these techniques into a digital environment, the reduction of organizational overhead is the main goal to foster accessibility. Still, we do not know if overhead reduction fosters creativity or if it eliminates an important…
Overview+Detail interfaces can be used to examine the details of complex data while retaining the data’s overall context. Dynamic data introduce challenges for these inter-faces, however, as moving objects may exit the detail view, as well as a person’s field of view if they are working at a large interactive surface. To address this “off-view”…
Triggering commands on large interactive surfaces is less efficient than on desktop PCs. It requires either large physical movements to reach an interaction area (e.g., buttons) or additional operations to call context menus (e.g., dwell). There is a lack of efficient ways to trigger shortcuts. We introduce Kolibri – a pen-based gesture system that allows…
Interactive Paper Interface Whether it is the to-do list stuck to the monitor, contact information jotted down during a telephone call, or a short message attached to a pile of documents passed over to a co-worker, paper is often the means of choice. Post-it notes in particular are the most popular paper medium for informal…
When multiple users are simultaneously sharing a workspace, it is not always clear what should happen when a user invokes an undo action. We explored different user interfaces for undo/redo for co-located collaborative workspaces, such as large interactive whiteboards. A preliminary study revealed that users expect neither a global nor personal undo, but rather a…
In this paper, we present the Harpoon selection tool, a novel selection technique specifically designed for interactive whiteboards. The tool combines area cursors and crossing to perform complex selections amongst a large number of unsorted, ungrouped items. It is optimized for large-scale pen-based surfaces and works well in both dense and sparse surroundings. We describe…
In this paper we present Geckos, a new type of tangible objects which are tracked using a Force-Sensitive Resistance sensor. Geckos are based on low-cost permanent magnets and can also be used on non-horizontal surfaces. Unique pressure footprints are used to identify each tangible Gecko. Two types of tangible object designs are presented: Using a…
In this project we present the NiCE Formula Editor, which recognizes handwritten formulas to provide in situ computation and visualization. Our editor uses a novel hardware setup, suitable for use as a desktop or whiteboard that disambiguates pen and multi-touch input. In our interface, the pen writes and performs gestures, while touch manipulates. Multiple users…
