Multi-display Composition: Supporting Display Sharing for Collocated Mobile Devices
نویسندگان
چکیده
Multi-display composition is a technique that enables several mobile devices to join together over a wireless network to form a larger logical display. This logical display can be created in an ad hoc manner for use when and where it is needed out of a group of users’ existing mobile computers. In this work we present a multi-display composition system and discuss our implementation that supports dynamically extending the display across several devices. Furthermore, we present findings from a study of collocated groups of individuals using multi-display composition on two different types of mobile computers. We found mixed results with respect to the effect of the resulting display area. The use of two devices by a pair of participants tended to be rated more favorably than a corresponding group of four devices and participants. Furthermore, while providing additional screen real estate for smaller UMPCs, tablets were rated more favorably when using our system. Finally, we discuss usage themes that emerged from participants’ use of the multi-display composition system.

Ubiquitous Media for Collocated Interaction
Ubiquitous media – the digital, multimodal content available to users through ubiquitous computing devices – holds out the promise of contextualising media objects better by making them closer to and integrating them with real-world situations. In this chapter, we present two systems that exemplify the opportunities of ubiquitous media in collocated user interaction. CityWall is a public multit...
متن کاملEnabling Pervasive Collaboration with Platform Composition
Emerging pervasive computing technologies present many opportunities to aid ad-hoc collocated group collaboration. To better understand ad-hoc collaboration using pervasive technologies, or Pervasive Collaboration, a design space composed of three axes (composition granularity, sharing models, and resource references) is outlined, highlighting areas that are only partially covered by existing s...
متن کاملExploring Computer Augmented Communication through an Examination of the Collocated Use of Multiple Mobile Displays
Computer supported collaborative work (CSCW) and specifically the subdomain of Computer Mediated Communication (CMC) has often focused on supporting face–to–face communication over a distance. This communication often has taken place in front of whiteboards [3] and large–scale displays [1], and more recently on the tabletop[4]. However, instead of studying large fixed devices around which group...
متن کاملDevelopment and Evaluation of an Interactive Mobile Learning Environment with Shared Display Groupware
When using mobile devices in support of learning activities, students gain mobility, but problems arise when group members share information. The small size of the mobile device screen becomes problematic when it is being used by two or more students to share and exchange information. This problem affects interactions among group members. To overcome the information sharing problem, the concept...

Copyright is held by the author/owner(s). CHI 2016 Workshop on Interacting with Multi-Device Ecologies "in the Wild", May 7, 2016, San Jose, CA, USA. Abstract Large vertical displays are increasingly widespread, and content sharing between them and personal mobile devices is central to many usage scenarios. Research has already led to manifold interaction techniques. In most cases however, they...
