HuddleLamp: Spatially-Aware Mobile Displays for Ad-hoc Around-the-Table Collaboration
TLDR
A novel hybrid sensing approach that uses RGB and depth data to increase tracking quality and a technical evaluation of its capabilities and limitations is contributed.
Fluid interaction for information visualization
TLDR
This article collects examples of visualizations with ‘best-in-class’ interaction and uses them to extract practical design guidelines for future designers and researchers to address the issue of interaction in visualization.
Blended Interaction: understanding natural human–computer interaction in post-WIMP interactive spaces
TLDR
This work introduces Blended Interaction, a new conceptual framework that helps to explain when users perceive user interfaces as “natural” or not, and introduces four domains of design to structure the underlying problem and design space: individual and social interaction, workflow, and physical environment.
Materializing the query with facet-streams: a hybrid surface for collaborative search on tabletops
TLDR
Two user studies reveal how Facet-Streams unifies visual and tangible expressivity with simplicity in interaction, supports different strategies and collaboration styles, and turns product search into a fun and social experience.
Connichiwa: A Framework for Cross-Device Web Applications
TLDR
Connichiwa is a versatile framework for creating web applications across multiple devices that base Connichiwa on four key goals: integration of existing devices, independence of network infrastructure, versatility of application scenario, and usability of its API.
Adaptive Pointing - Design and Evaluation of a Precision Enhancing Technique for Absolute Pointing Devices
TLDR
A novel classification scheme is introduced to more clearly discriminate between different approaches to improve pointing performance for absolute input devices by implicitly adapting the Control-Display gain to the current user's needs without violating users' mental model of absolute-device operation.
Adaptive personal territories for co-located tabletop interaction in a museum setting
TLDR
A novel, tabletop-integrated multi-user tracking system that provides data on a user's location and movement is implemented and an interaction design is presented that assigns a visually separated display space to each user, the space serving them as a personal territory.
Spatially-aware or Spatially-agnostic?: Elicitation and Evaluation of User-Defined Cross-Device Interactions
TLDR
The results indicate that spatially-aware techniques are preferred by users and can decrease mental demand, effort, and frustration, but only when they are designed with great care.
Squidy: a zoomable design environment for natural user interfaces
TLDR
The interaction library Squidy is introduced, which eases the design of natural user interfaces by unifying relevant frameworks and toolkits in a common library and allows users to adjust the complexity of the user interface to their current need and knowledge.
Design and Implementation of Post-WIMP Distributed User Interfaces with ZOIL
TLDR
The Zoomable Object-Oriented Information Landscape (ZOIL) is introduced, a novel design approach and software framework for post-WIMP DUIs in interactive spaces that facilitates the implementation of ZOIL's design principles in practice.
