---Workshop Theme---

The use of Augmented Reality (AR) technologies in everyday life and work is one of the major trends. Augmented Reality means spatially overlaying virtual data on top of the real world, allowing the flexibility of virtual reality to be used for collaboration while being grounded in physical reality (Azuma et al., 2001; Azuma & others, 1997). New developments in AR – such as data glasses - change the way individuals interact with the real world, and it offers several possibilities for the support of cooperation.

Collaborative applications of Augmented Reality have been a popular field of work and discussion among researchers and developers since the early days of Augmented Reality. While at this time Augmented Reality technology (especially the hardware) was clumsy, heavy and hard to imagine being used on a daily basis, nowadays hardware and software for AR is ready to be used in everyday work and life.

Despite the readiness of technology, available work and researchers dealing with Augmented Reality in cooperative scenarios augmented reality, the topic has not been prominent at CSCW conferences recently. Rather than that AR-Applications are currently predominately discussed in (individual) human-computer interaction scenarios or from a technical viewpoint only. However, there are many opportunities stemming from recent technology developments in Augmented Reality for CSCW that our community should more systematically be working on.

We believe augmented reality will be one of the most prominent future topics in CSCW. An upcoming special issue in Journal for Computer Supported Cooperative Work (jCSCW) and workshops on collaboration and augmented reality at ISMAR are initial efforts to systematically deal with collaborative applications of Augmented Reality and at the same time show the growing interest in this topic. The workshop aims to bundle this interest and bring together a group of researchers from CSCW (and practitioners) working on augmented reality for cooperation support.

---Goal(s), Research Questions and Topics---

The workshops strives to raise awareness for AR in CSCW and to form a group of interested peers working on collaborative Augmented Reality. Questions to be answered in this initial workshop include, but are not limited to:

* Which are approaches and scenarios for using AR in computer-supported collaboration?
* What are the potentials and pitfalls of using AR in computer-supported collaboration?
* What are the major challenges for using AR in computer-supported collaboration?
* How can AR be used to enhance computer-supported collaboration?
* What kind of evaluation methods are needed to investigate the usability and usefulness of AR-supported collaboration?

In the workshop we will strive to work together with the participants on answering these questions. Interested researchers and practitioners are invited to submit different kinds of contributions, including mostly theoretical work, empirical studies and prototypes. In particular, the workshop welcomes (but is not limited to) the following kinds of contributions:

* Settings and scenarios for augmented reality supported collaboration
* Studies on collaboration with augmented reality
* Design considerations for AR in collaborative settings
* Relations between AR and theories or frameworks from CSCW and related fields
* Frameworks for mixed-reality-supported collaboration
* Tools and prototypes supporting computer-supported collaboration with AR


---Submission---

We will accept contributions in two different formats:

- Research papers such as reports of empirical studies, research in progress and position papers, which may not exceed 8 pages.
- Position papers, which deal with theoretical and conceptual considerations or with scenarios and requirements in the context of AR-supported collaboration (8 pages).
- Demo papers describing systems for collaboration supported or enabled by augmented reality, which may not exceed 3 pages. There will be time during the workshop to demo and discuss these systems and therefore we expect you to bring your system or a poster to the workshop.

All contributions have to be formatted according to the ECSCW formatting instructions and must be submitted in PDF format via EasyChair.

Author kits and paper templates are available at the ECSCW website (http://www.ecscw2015.no).

The selection process will be a double blind review through an international program committee.

All accepted paper will be published electronically at CEUR Workshop Proceedings. Means for further publications of the results are currently in the planning and will be reported on the workshop website once agreements with journal editors have been reached.

---Venue---

In 2015 the European conference on Computer-Supported Cooperative Work – ECSCW – will be held September 19-23 in Oslo, Norway. ECSCW is a series of international conferences on computer-supported cooperative work located in Europe. The conference series is affiliated with the European Society for Socially Embedded Technologies (EUSSET). CSCW focuses on enhancing our understanding of the practices of cooperative work aiming to explore and design technological support. The ECSCW conference is an important venue for defining and further develop the agenda of CSCW research.
