Ambient light is starting to be commercially used to enhance the viewing experience for watching TV. We believe that ambient light can add value in meeting and control rooms that use large vertical interactive surfaces. Therefore, we equipped a large interactive whiteboard with a peripheral ambient light display and explored its utility for different scenarios…
Structuring and rearranging free-hand sketches on large interactive surfaces typically requires making multiple stroke selections. Without well-designed selection tools, this can be both time-consuming and fatiguing. Investigating the concept of automated clustering, we conducted a background study to understand the varying perspectives of how elements in sketches can be grouped. In response to these…
Idea Archipelago allows users to collect, organize, and share all project related information assets. It can be defined as a project management tool that helps organizing data. The prototype introduces a novel visualization, designed for direct pen-based interaction on digital whiteboards, with the purpose of supporting long-term design projects. Our design has been guided by…
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…
