The emergence and widespread use of personal computers and network technologies have seen the development of interest in the use of computers to support cooperative work. This volume presents the proceedings of the tenth European conference on Computer Supported Cooperative Work (CSCW). This is a multidisciplinary area that embraces the development of new technologies grounded in actual cooperative practices.

These proceedings contain a collection of papers addressing novel interaction technologies for CSCW systems, new models and architectures for groupware systems, studies of communication and coordination among mobile actors, studies of cooperative work in complex settings, studies of groupware systems in actual use in real-world settings, and theories and techniques to support the development of cooperative applications. The papers present emerging technologies alongside new methods and approaches to the development of this important class of applications.

This book constitutes the proceedings of the 17th Collaboration Researchers' International Working Group Conference on Collaboration and Technology, held in Paraty, Brazil, in October 2011.
The 12 revised papers presented together with 6 short papers were carefully reviewed and selected from numerous submissions. They are grouped into four themes that represent current areas of interest in groupware research: theoretical foundation, empirical studies, methods and techniques, and tools for communication and cooperation.

This book constitutes the refereed proceeding of the 23rd International Conference on Collaboration and Technology, CRIWG 2017, held in Saskatoon, Canada, in August 2017. The 14 full papers presented together with 5 work-in-progress papers were carefully reviewed and selected from 33 submissions. The papers focus on collaboration technology design, development, and evaluation. The background research is influenced by a number disciplines, such as computer science, management science, information systems, engineering, psychology, cognitive sciences, and social sciences

Spatial memory is an important facet of human cognition - it allows users to learn the locations of items over time and retrieve them with little effort. In human-computer interfaces, a strong knowledge of the spatial location of controls can enable a user to interact fluidly and efficiently, without needing to visually search for relevant controls. Computer interfaces should therefore be designed to provide support for developing the user's spatial memory, and they should allow the user to exploit it for rapid interaction whenever possible. However, existing systems offer varying support for spatial memory. Many modern interfaces break the user's ability to remember spatial locations, by moving or re-arranging items; others leave spatial memory underutilised, requiring slow sequences of mechanical actions to select items rather than exploiting users' strong ability to index items and controls by their on-screen locations. Supporting and Exploiting Spatial Memory in User Interfaces highlights the importance of designing for spatial memory in HCI.It summarises empirical results on spatial memory from both the psychology and HCI domains, identifying a set of observable properties of spatial memory that can be used to inform design. It also analyses existing interfaces in the HCI literature that support or disrupt spatial memory, including space-multiplexed displays for command and navigation interfaces, different techniques for dealing with large spatial data sets, and the effects of spatial distortion. Supporting and Exploiting Spatial Memory in User Interfaces provides strong evidence that spatial knowledge of controls and data enables rapid interaction and information retrieval, and allows users to focus more of their cognitive resources on the task at hand, rather than on the interface. It is aimed at user interface designers, as well as other HCI researchers interested in spatial memory. Useful guidelines for designers are identified throughout the book, which provide clear advice on how and when to design with spatial memory in mind.Similarly, the concluding summary of the area, as well as methodological cautions and directions for future research provide an excellent resource for scientists interested in the importance of spatial memory in user interfaces.
