tl;dr: Mixed-focus collaboration in remote work is challenging, as it involves switching between individual and group tasks while staying aware of others' activities. This paper presents Peek-at-You, a system that integrates collaboration and communication software to provide collaborative features…

tl;dr: Virtual reality (VR) users are disconnected from the physical environment, which leaves them vulnerable to being unknowingly observed by bystanders. Similarly, a VR user might use a headset's recording functionality to spy on bystanders. We propose Vice VRsa, a system that promotes mutual…

Knowledge work increasingly spans multiple computing surfaces. Yet in status quo user experiences, content as well as tools, behaviors, and workflows are largely bound to the current device—running the current application, for the current user, and at the current moment in time. SurfaceFleet is a s…

Driven by technological advancements, we now own and operate an ever-growing number of digital devices, leading to an increased amount of digital data we produce, use, and maintain. However, while there is a substantial increase in computing power and availability of devices and data, many tasks we…

The availability of mobile device ecologies enables new types of ad-hoc co-located decision-making and sensemak-ing practices in which people find, collect, discuss, and share information. However, little is known about what kind of device configurations are suitable for these types of tasks. This…

Research with interactive tabletop displays has shown much promise for collaborative scenarios. However, tabletops never became a commercial success and rarely exist outside the research community. Being relatively expensive, heavy and immobile hardware, and only limited availability of commercial…

Smartwatches are characterized by their small size designed for wearability, discretion, and mobile interactions. Most of the interactivity, however, is limited to the size of the display, introducing issues such as screen occlusion and limited information density. We introduce Wristband.io, a…

For digital content curation of historical artefacts, curators collaboratively collect, analyze and edit documents, images, and other digital resources in order to display and share new representations of that information to an audience. Despite their increasing reliance on digital documents and…

Curating historic documents and artefacts is a demanding task, requiring collecting, reviewing, and combining a large collection of raw material from different sources. While digital technologies can support such curation activities, the devices often work in isolation and do not well support the…

Notice board goes 2.0: publyboard is the new digital version of a public bulletin board. The concept draws heavily from the well established interaction techniques with a non-digital bulletin board. You can post on a board, take posts with you and even interact with posts. We developed publyboard…

Displays are growing in size, and are increasingly deployed in semi-public and public areas. When people use these public displays to pursue personal work, they expose their activities and sensitive data to passers-by. In most cases, such shoulder-surfing by others is likely voyeuristic vs. a…

When a person interacts with a display in an open area, sensitive information becomes visible to shoulder-surfing passers-by. While a person’s body shields small displays, shielding is less effective as display area increases. To mitigate this problem, we sense spatial relationships between the p…
