Extracting Paper Sticky Notes with Visual-Inertial Odometry of ARKit

Abstract: Post-it notes are popular on meetings, such as brainstorming or card sorting. On brainstorming, we arrange paper cards for grouping. The positional relationship of paper notes is important. However, there is a problem between an image resolution and positional relationship of paper notes. Extraction of the paper notes content requires high resolution image data. As a capture point is close to paper notes, positional relationship of paper notes is less clear. More and more paper notes make that problem tangible. We present a method to solve the trade-off problem about the positional relationship on extracting paper sticky notes. We developed three extract mode: Single shot, Semi auto, and Full auto. Our method extends the area where we use for brainstorming. The result of experimental evaluation shows that our system can project virtual cards at the same position as the original accurately.

Developing a Management System and Interface for Instant Application Window Sharing

Abstract: The sharing of application windows among multiple PCs is needed to support collaborative works. It enables users to manipulate windows from different PCs when using their own PCs. However, creating native applications with a sharing function is time consuming. We therefore developed an application window sharing system using web technology. Moreover, we developed a dongle interface for an application sharing system. This enables users to start the sharing of application windows smoothly. We tested and evaluated the practically of our system. The time required to start the application window sharing was shown to be less than 2,000 ms. The present paper describes how the system can be used for practical applications.

Developing a Linked Data-Based Weekly Report Management System

Abstract: New students assigned to a laboratory learn lessons from their predecessors by referring to previous reports Our laboratory has accumulated weekly reports over more than twenty years in our weekly report management system, however, students have difficulty with searching for valuable weekly reports from the report system We aim to extend the existing weekly report management system to help users find valuable past weekly reports We introduce the idea of linked data to the report management system We designed the Weekly Report Network to represent weekly reports relevant to submissions Moreover, we implemented a publication-based search function, a visualization function, and a compilation function on the existing weekly report system to enable reuse of the accumulated weekly reports for twenty years First, the publication-based search function enables users to find weekly reports relevant publications The works contain a paper registration, a paper submission, a camera-ready submission, and a presentation Second, the visualization function illustrates an overview of research activities based on weekly reports for a year For example, the system makes a graph to show time spent on research activities described in weekly reports Finally, the compilation function makes an annual report by concatenating and editing weekly reports for the year This paper explains the Weekly Report Network and the implementation of the extended weekly report management system
