CommenTV enables users to share their comments in parallel with time-based content. CommenTV utilizes existing web technologies to enhance current TV or video player solutions with a new type of comment system. CommenTV is able to take and display texts, images, and related videos as social comments. In this way, the CommenTV users can experience audiovisual content that blends with their social networks by sharing comments. Ultimately, CommenTV can be a social bookmarking system for audiovisual content that informs content creators about how viewers perceive their content and lets viewers participate in creating a more social content.

In this paper, the author presents DynamiCross, a system that enables users to dynamically represent and share information in cross-reality. Recently, designers and meeting attendees have enhanced engagement through a multiple display environments (MDE) [2, 5], which include not only personal objects, such as papers and laptops, but also shared objects, such as large displays, to provide collaborators with a virtual workspace. In this paper, the author describes how DynamiCross can support the user's individual or collaborative information handling with its cross-reality interfaces and multiple displays. In addition, when a user's personal material is placed on a large display, the display becomes a multilayer display that uses augmented reality (AR) technology to show digital contents of the personal object. The author introduces three major functions of the system to explain these capabilities which could be beneficial to similar research on cross-reality collaborations and paper interactions.

We introduce TwinSpace, a flexible software infrastructure for combining interactive workspaces and collaborative virtual worlds. Its design is grounded in the need to support deep connectivity and flexible mappings between virtual and real spaces to effectively support collaboration. This is achieved through a robust connectivity layer linking heterogeneous collections of physical and virtual devices and services, and a centralized service to manage and control mappings between physical and virtual. In this paper we motivate and present the architecture of TwinSpace, discuss our experiences and lessons learned in building a generic framework for collaborative cross-reality, and illustrate the architecture using two implemented examples that highlight its flexibility and range, and its support for rapid prototyping.

MobileAct is an interactive visualization tool that enables users to create their own visualizations and integrate visualized information into their daily tasks. It provides a novel interaction mechanism in which the mobile, one of the most well-known kinetic art forms, is used as an interactive visualization. The mobile structure transparently presents contextually relevant, balanced, and user-specific information through its key features, connectivity, and equilibrium. MobileAct's connected frame allows for visualization of hierarchical or relative information. Users can set structures and balancing factors of their data components based on their importance or frequency level. Using its balancing and scalable capabilities, users can obtain reflective feedback regarding their data patterns. The applications of MobileAct are designed and presented to describe its implementation details. Lastly, this paper suggests how MobileAct can be improved and how its design pattern will benefit future interactive visualizations.
