We propose a method to reduce the inconsistency between virtual and real spaces in manipulating 3D virtual objects with users’ fingers. By elasticizing a virtual object, our system prevents users’ fingers from thrusting into the virtual object and enables 3D interaction with a greater sense of reality.

A Multitouch Scrum Task Board is presented, which is designed for being used by a team synchronously during face-to-face collaboration. Tasks can be created, explored, sorted, resized, and visually arranged in parallel simultaneously by multiple users on a multitouch display. We present our first experiences using the cooperative Scrum Task Board on a multitouch table.

This paper introduces a concept of using a home devices mashup tool to wire home devices on a tabletop display in combination with web based UIs on mobile devices to control home devices. This multi-display system supports multiple people to deploy home networked devices co-located collaboratively and control home devices universally with high accessibility and mobility.

Bancada is a system developed for the exploration of geospatial information in multi-display environments. Users interact with tablets (Zoomable Magic Lenses) to augment an overview map displayed on a tabletop. Bancada is currently being used to research user interfaces separated across multiple devices and interactions with high-resolution mobile devices.

Node-link diagrams are the predominant visualization for relations in data. However, nodes' temporal properties are difficult to visualize. Combining timeline and graph visualization, we introduce Time Shadows and Time Beads. Time Shadows provide temporal context for nodes. Time Beads present a new form of timeline supporting continuous and discrete navigation, and multiple focus regions.

Corona is a wearable haptic feedback device that uses electrostatic force to provide physical stimuli when a user touches objects that are electrically grounded, or of opposite polarity. Unlike previous approach, we neither physically actuate objects nor use any hand-worn tactile feedback devices. We introduce a mechanism to artificially build up electrostatic charge within the human body.

Cyber Chamber system that provides a novel online shopping environment in which several people can shop together in same room, using tablets and projector.

We evaluate the relation between visual and haptic feedback in a 3D touch panel interface and show the optimal latency for natural interaction. The result showed that the visual synchronization of finger and button movements is more important than visual and haptic synchronization.

In this paper we present our early work in the exploration of a multi-surface prototype to create immersive retail environments. Our goal was to utilize interactive devices to explore interactions in a spatially aware retail environment.

We propose the Intelligent Ink Annotation Framework that helps the system to increase learnability of annotation systems by detecting recognizable intentions from natural annotation behavior on paper-based documents. Our framework recognizes "Targeting Content" and "Commenting", which are related to extraction of annotation information.

Interact! is an evidence-based framework for the support of school class visits to science exhibitions featuring a large vertical multi-touch surface and a set of tablet computers. The framework is designed to foster interest in computer sciences and collaborative learning by drawing upon subject areas of personal importance and encouraging small group knowledge processes

We presented a new infrastructure that allows dynamic reconfiguration of the interactive space by grouping different devices together. The architecture is based on a Web server and websockets that enables rapid pairing of devices, and simple magnetic switches to provide location awareness of devices relative to each others.

This approach integrates barcodes into tactile maps to allow their detection by standard smartphones' cameras. A mobile application automatically obtains more detailed map data to auditively support the user's exploration of the tactile map. An experimental implementation shows the principal feasibility and provides the basis for comprehensive user studies.

This poster describes how the content of a tabletop as well as the corresponding deictic gestures can be made accessible to blind users. Using LEAP Motion sensors and sensor fusion, deictic gestures are detected and output to the blind user together with the serialized content of the tabletop.

This work presents a design space in which personal devices are used as a means to facilitate “socially safe”, ad-hoc interaction with large public displays. We identify barriers hindering this process, and focus on minimizing the effort required to initiate, sustain, and withdraw from interaction with a large public display.

We present “Second Look”, a platform of interactive surfaces and wearable computing for helping people, in particular creative writers, to overcome writer’s block. The novelty of our systems stems from the addition of wearable devices (Google Glass) and crowdsourcing to improve creative writing on tablets and phones.

We describe the design of a novel tangible, paper-based tabletop application for learning about fractions collaboratively. We also describe in detail how we designed its interface with a single element of control (locus of control) to foster equal participation, and how the analysis of its position and rotation can provide insights on the collaboration processes of students.

In this initial study, we used a mobile eye-tracker to follow the facilitator's cognitive load in several simulated lessons with real school children, conducted in a multi-tabletop environment. The video coding of high- and low-load episodes provided insights on what aspects of managing such multi-tabletop setting can be more challenging for a teacher (e.g., class-wide awareness).

We present MultiTask, a hybrid tabletop/mobile system to enable face-to-face discussion, editing and assignment of tasks related to a project team.

Most solutions to navigate 3D virtual environments using small handheld devices rely on multi-touch, which is not always feasible. ThumbCam is a novel single-touch technique for camera manipulation, which allows users to move and look around using only the thumb, offering more operations with a single touch than existing techniques.

We conducted an in-situ user study by visiting 22 households and exploring specific use cases and ideas of portable projector-camera systems in a domestic environment. Using a grounded theory approach, we identified several categories such as interaction techniques, presentation space, placement and use cases. Based on our observations, we designed and implement UbiBeam, a domestically deployable projector-camera system.

A novel system for interactive evaluation and verification of manual assembly processes will be presented. The approach utilizes a scalable, interactive augmented floor surface in combination with a tangible tabletop hardware and a material zone planning software. The floor projection hardware is used for true to scale assembly station layout visualizations.

We draw upon existing work in the area of touch accuracy and touch menus to contribute the X-O Arch Menu, which seamlessly combines precise positioning and fast, hierarcial menu selection. Furthermore, we introduce a novel optimization to pie menus that allows usage in limited screen space.
