Hacking with Multi-touch for Java (MT4j)

Developing applications for touch devices is hard. Developing touch based applications for multi-user input is harder. The Multi-Touch for Java (MT4j) toolkit supports developing touch based applications for multiple users. In this paper, we outline our experience using MT4j for developing a number of software applications to support developers working in co-located teams. Our experience using the toolkit will help developers to understand the nuances of the toolkit and design issues that can be applied to other toolkits for developing multi-user touch based applications

Multi-person Spatial Interaction in a Large Immersive Display Using Smartphones as Touchpads

In this paper, we present a multi-user interaction interface for a large immersive space that supports simultaneous screen interactions by combining (1) user input via personal smartphones and Bluetooth microphones, (2) spatial tracking via an overhead array of Kinect sensors, and (3) WebSocket interfaces to a webpage running on the large screen. Users are automatically, dynamically assigned personal and shared screen sub-spaces based on their tracked location with respect to the screen, and use a webpage on their personal smartphone for touchpad-type input. We report user experiments using our interaction framework that involve image selection and placement tasks, with the ultimate goal of realizing display-wall environments as viable, interactive workspaces with natural multimodal interfaces.Comment: 8 pages with reference

Agile Processes in Software Engineering and Extreme Programming

This open access book constitutes the proceedings of the 23rd International Conference on Agile Software Development, XP 2022, which was held in Copenhagen, Denmark, in June 2022. XP is the premier agile software development conference combining research and practice. It is a unique forum where agile researchers, practitioners, thought leaders, coaches, and trainers get together to present and discuss their most recent innovations, research results, experiences, concerns, challenges, and trends.  XP conferences provide an informal environment to learn and trigger discussions and welcome both people new to agile and seasoned agile practitioners. This year’s conference was held with the theme “Agile in the Era of Hybrid Work”. The 13 full papers and 1 short paper presented in this volume were carefully reviewed and selected from 40 submissions. They were organized in topical sections named: agile practices; agile processes; and agile in the large

Interactive digital cardwalls for Agile software development

Agile software development is characterized by very intensive communication and collaboration among members of the software development team and external stakeholders. In this context, we look specifically at cardwalls, noting that despite the wide availability of digital cardwalls, most Agile teams still use physical cardwalls to support their collaborative events. This is true even though a physical cardwall hinders efficient distributed software development and causes extra effort to capture story artefacts into digital tools to meet traceability and persistence requirements. We conducted two empirical studies in industry to understand the use of existing digital Agile cardwalls and to find out the needs for an ideal digital Agile cardwall. The first study was with eight Agile teams of committed digital cardwall users. The study showed the reasons why some teams use projected digital cardwalls and their detailed experiences with them. The study showed that most digital cardwalls seem not be sufficient for the highly interactive and collaborative Agile workstyle. The second study was with eleven Agile companies. The study comprised of the development of aWall, a software prototype of a large interactive high-resolution multi-touch display that supports varied Agile meetings where cardwalls are used. The results of the study e
