Light on horizontal interactive surfaces: Input space for tabletop computing
In the last 25 years we have witnessed the rise and growth of interactive tabletop research, both in academic and in industrial settings. The rising demand for the digital support of human activities motivated the need to bring computational power to table surfaces. In this article, we review the state of the art of tabletop computing, highlighting core aspects that frame the input space of interactive tabletops: (a) developments in hardware technologies that have caused the proliferation of interactive horizontal surfaces and (b) issues related to new classes of interaction modalities (multitouch, tangible, and touchless). A classification is presented that aims to give a detailed view of the current development of this research area and define opportunities and challenges for novel touch- and gesture-based interactions between the human and the surrounding computational environment. © 2014 ACM.This work has been funded by Integra (Amper Sistemas and CDTI, Spanish Ministry of Science and Innovation) and TIPEx (TIN2010-19859-C03-01) projects and Programa de Becas y Ayudas para la Realización de Estudios Oficiales de Máster y Doctorado en la Universidad Carlos III de Madrid, 2010
Extending mobile touchscreen interaction
Touchscreens have become a de facto interface for mobile devices, and are penetrating further beyond their core application domain of smartphones. This work presents a design space for extending touchscreen interaction, to which new solutions may be mapped. Specific touchscreen enhancements in the domains of manual input, visual output and haptic feedback are explored and quantitative and experiental findings reported. Particular areas covered are unintentional interaction, screen locking, stereoscopic displays and picoprojection. In addition, the novel interaction approaches of finger identification and onscreen physical guides are also explored. The use of touchscreens in the domains of car dashboards and smart handbags are evaluated as domain specific use cases.
This work draws together solutions from the broad area of mobile touchscreen interaction. Fruitful directions for future research are identified, and information is provided for future researchers addressing those topics.Kosketusnäytöistä on muodostunut mobiililaitteiden pääasiallinen käyttöliittymä, ja ne ovat levinneet alkuperäiseltä ydinsovellusalueeltaan, matkapuhelimista, myös muihin laitteisiin. Työssä tutkitaan uusia vuorovaikutuksen, visualisoinnin ja käyttöliittymäpalautteen keinoja, jotka laajentavat perinteistä kosketusnäytön avulla tapahtuvaa vuorovaikutusta. Näihin liittyen väitöskirjassa esitetään sekä kvantitatiivisia tuloksia että uutta kartoittavia löydöksiä. Erityisesti työ tarkastelee tahatonta kosketusnäytön käyttöä, kosketusnäytön lukitusta, stereoskooppisia kosketusnäyttöjä ja pikoprojektoreiden hyödyntämistä. Lisäksi kartoitetaan uusia vuorovaikutustapoja, jotka liittyvät sormien identifioimiseen vuorovaikutuksen yhteydessä, ja fyysisiin, liikettä ohjaaviin rakenteisiin kosketusnäytöllä. Kosketusnäytön käyttöä autossa sekä osana älykästä käsilaukkua tarkastellaan esimerkkeinä käyttökonteksteista. Väitöskirjassa esitetään vuorovaikutussuunnittelun viitekehys, joka laajentaa kosketusnäyttöjen kautta tapahtuvaa vuorovaikutusta mobiililaitteen kanssa, ja johon työssä esitellyt, uudet vuorovaikutustavat voidaan sijoittaa.
Väitöskirja yhdistää kosketusnäyttöihin liittyviä käyttöliittymäsuunnittelun ratkaisuja laajalta alueelta. Työ esittelee potentiaalisia suuntaviivoja tulevaisuuden tutkimuksille ja tuo uutta tutkimustietoa, jota mobiililaitteiden vuorovaikutuksen tutkijat ja käyttöliittymäsuunnittelijat voivat hyödyntää

Designing for Cross-Device Interactions
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 conduct with our devices are not well connected across multiple devices. We conduct our tasks sequentially instead of in parallel, while collaborative work across multiple devices is cumbersome to set up or simply not possible. To address these limitations, this thesis is concerned with cross-device computing. In particular it aims to conceptualise, prototype, and study interactions in cross-device computing. This thesis contributes to the field of Human-Computer Interaction (HCI)—and more specifically to the area of cross-device computing—in three ways: first, this work conceptualises previous work through a taxonomy of cross-device computing resulting in an in-depth understanding of the field, that identifies underexplored research areas, enabling the transfer of key insights into the design of interaction techniques. Second, three case studies were conducted that show how cross-device interactions can support curation work as well as augment users’ existing devices for individual and collaborative work. These case studies incorporate novel interaction techniques for supporting cross-device work. Third, through studying cross-device interactions and group collaboration, this thesis provides insights into how researchers can understand and evaluate multi- and cross-device interactions for individual and collaborative work. We provide a visualization and querying tool that facilitates interaction analysis of spatial measures and video recordings to facilitate such evaluations of cross-device work. Overall, the work in this thesis advances the field of cross-device computing with its taxonomy guiding research directions, novel interaction techniques and case studies demonstrating cross-device interactions for curation, and insights into and tools for effective evaluation of cross-device systems
AirConstellations: In-Air Device Formations for Cross-Device Interaction via Multiple Spatially-Aware Armatures
AirConstellations supports a unique semi-fixed style of cross-device interactions via multiple self-spatially-aware armatures to which users can easily attach (or detach) tablets and other devices. In particular, AirConstellations affords highly flexible and dynamic device formations where the users can bring multiple devices together in-air - with 2-5 armatures poseable in 7DoF within the same workspace - to suit the demands of their current task, social situation, app scenario, or mobility needs. This affords an interaction metaphor where relative orientation, proximity, attaching (or detaching) devices, and continuous movement into and out of ad-hoc ensembles can drive context-sensitive interactions. Yet all devices remain self-stable in useful configurations even when released in mid-air. We explore flexible physical arrangement, feedforward of transition options, and layering of devices in-air across a variety of multi-device app scenarios. These include video conferencing with flexible arrangement of the person-space of multiple remote participants around a shared task-space, layered and tiled device formations with overview+detail and shared-to-personal transitions, and flexible composition of UI panels and tool palettes across devices for productivity applications. A preliminary interview study highlights user reactions to AirConstellations, such as for minimally disruptive device formations, easier physical transitions, and balancing "seeing and being seen"in remote work
ShapeBots: Shape-changing Swarm Robots
We introduce shape-changing swarm robots. A swarm of self-transformable
robots can both individually and collectively change their configuration to
display information, actuate objects, act as tangible controllers, visualize
data, and provide physical affordances. ShapeBots is a concept prototype of
shape-changing swarm robots. Each robot can change its shape by leveraging
small linear actuators that are thin (2.5 cm) and highly extendable (up to
20cm) in both horizontal and vertical directions. The modular design of each
actuator enables various shapes and geometries of self-transformation. We
illustrate potential application scenarios and discuss how this type of
interface opens up possibilities for the future of ubiquitous and distributed
shape-changing interfaces.Comment: UIST 201
