DoubleMe: Local Blending in Multi-Display Environments with Augmented Reality to Facilitate Co-Located Collaboration

Co-located collaboration often raises challenges related to physical constraints because of , e.g., stationary display setups or limited possibilities of movement. We introduce DoubleMe, an Augmented Reality system that generates virtual duplicates of collaborators' workspaces, comprising both their displays and avata…

Investigating Hand-Bound Pads for AR Input Using Hand-Tracking Only

Interaction in Augmented Reality primarily relies on raycast pointing and mid-air touch. An alternative consists of using the non-dominant hand as a touch-sensitive surface, enabling more comfortable, less fatiguing input. AR UI design guidelines have so far discouraged this alternative because of poor hand tracking p…

EuterPen: Unleashing Creative Expression in Music Score Writing

Music notation programs force composers to follow the many rules of the staff notation when writing music and constantly seek to optimize symbol placement, making numerous adjustments automatically. Even though this impedes their creative process, many composers still use them throughout their workflow, for lack of a…

Challenges of Music Score Writing and the Potentials of Interactive Surfaces

Composers use music notation programs throughout their creative process. Those programs are essentially elaborate structured document editors that enable composers to create high-quality scores by enforcing musical notation rules. They effectively support music engraving, but impede the more creative stages in the com…

TriPad: Touch Input in AR on Ordinary Surfaces with Hand Tracking Only

TriPad enables opportunistic touch interaction in Augmented Reality using hand tracking only. Users declare the surface they want to appropriate with a simple hand tap gesture. They can then use this surface at will for direct and indirect touch input. TriPad only involves analyzing hand movements and postures, withou…

SurfAirs: Surface + Mid-air Input for Large Vertical Displays

Large vertical surfaces such as wall displays allow users to work with a very large and high-resolution workspace. Such displays pro- mote physical navigation: users can step close to the display to see details, but also move away to get a wider view of the workspace. In terms of input, current solutions usually combi…

WallTokens: Surface Tangibles for Vertical Displays

Tangibles can enrich interaction with digital surfaces. Among others, they support eyes-free control or increase awareness of other users' actions. Tangibles have been studied in combination with horizontal surfaces such as tabletops, but not with vertical screens such as wall displays. The obvious obstacle is gravity…

ActiveInk: (Th)Inking with Data

During sensemaking, people annotate insights: underlining sentences in a document or circling regions on a map. They jot down their hypotheses: drawing correlation lines on scatterplots or creating personal legends to track patterns. We present ActiveInk, a system enabling people to seamlessly transition between explo…

Animated Edge Textures in Node-Link Diagrams: a Design Space and Initial Evaluation

Network edge data attributes are usually encoded using color, opacity, stroke thickness and stroke pattern, or some combination thereof. In addition to these static variables, it is also possible to animate dynamic particles flowing along the edges. This opens a larger design space of animated edge textures, featuring…

Designing Coherent Gesture Sets for Multi-scale Navigation on Tabletops

Multi-scale navigation interfaces were originally designed to enable single users to explore large visual information spaces on desktop workstations. These interfaces can also be quite useful on tabletops. However, their adaptation to co-located multi-user contexts is not straightforward. The literature describes diff…
