An interactive animation is a presentation of moving pictures that behave dynamically according to the input from users. It can be composed of animation characters modeled as finite-state machines. Based on the fact that the behavior of a finite-state machine can be defined by a state-transition diagram, an interactive animation authoring tool called Islay has been developed. Islay allows users to...
Social media such as Twitter and Facebook have become popular. In the age of social media, many people have become more active online. Personal branding is a very important strategy for capitalizing on individual strong points. This kind of branding is expected to contribute to self-actualization.

This paper proposes a remote control system of Sphero using a web browser. Sphero is a robotics ball that is controlled by using a smartphone. A user can control Sphero using Android or iOS application. However, the user is supposed to be with the Sphero. We provides a remote control system as a web application. The user can control Sphero using a web browser. The Sphero connects to a smartphone and...
In the real world, sticky notes are often used to mark important pages in the documents with some notes. Sticky notes sticking out of documents are so visible that we can easily locate where the information is. Existing word-processing software is capable of managing virtual sticky notes inside the files. But we cannot see them until we open the files. In this study, we develop a file manager that...
Due to the recent popularization of Geographic Information Systems (GIS), spatial network environments that can display the changes of spatial axes in mobile phones have received much attention. In addition, many users use location-based services, which are one input devices of GIS. Many researchers have proposed methods of k-Nearest Neighbor (kNN) search that have a bi-directional relationship from...
The recent development of hybrid broadcasting environments has meant that video delivery has attracted great attention. In hybrid broadcasting environments, clients can receive data both from a broadcasting system and a communication system. Some interruption time reduction methods have been proposed for video delivery in these environments. However, in these methods, the server does not change the...
Time series data often contain uncertainty due to various reasons, and the similarity search over uncertain time series data has been applied in many applications. For this reason, many methods have been proposed, and DUST is one of the latest methods that can deal with arbitrary probability distributions. However, it is known that its computational cost is high in particular when the dataset is large...
