Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
For high skilled players, an easy game might become boring and for low skilled players, a difficult game might become frustrating. The purpose of this research was to create new and better ways to offer players with different skills, an appropriate experience. We focused on adapting the difficulty levels of a simple 2D platform game, designing and building levels automatically. The proposed method...
The degree of difficulty is a key element of fun in digital games. Players enjoy games and improve their skills if the difficulty is set in their personal Flow Zones. The existing Dynamic Difficulty Adjustment (DDA) is a suitable technique to automatically control the difficulty within the proper range in games. However, sometimes players feel uncomfortable when they recognize that the difficulty...
Animation and game are very popular in Japan. Many works in animation and game have been released, and many characters have been produced. It is an important factor to select appropriate voice actors so that we can appropriately impress the characters. Based on this idea, we are developing a prototype of voice actor recommendation tool. We recorded voice performance from portable games and calculated...
Sign language is a very important communication tool for hearing-impaired people and also for the communication between hearing-impaired and non-handicapped people. There are many methods for sign language recognition, some of which are based on Hidden Markov Model (HMM) and others are based on Support Vector Machine (SVM) and so forth. In fact, the most of previous methods recognize fingerspelling...
The tracking of wind field circulation is an important and difficult problem in typhoon forecasting. This paper studies how to catch the shape and intensity deformation characteristics of this type of severe weather system, which includes the wind field estimation and typhoon structure prediction in a short period of time. A correlation matching approach is used to retrieve typhoon wind field without...
In recent years, services that use position estimation by Bluetooth Low Energy (BLE) are extensively being used. However, the technology itself is not used optimally owing to the high cost of installation at a base station. To solve this problem, we constructed and operated a system capable of visualizing the location information of a hotel key, and conducted an experiment to verify its functionality...
The beginner counselors have more likely to continue counseling in their own interest, they have a high tendency to make great use of the closed-ended question in order to confirm the interpretation with the client. While expert counselors are instructing the counseling skill to beginner counselors, we consider that the reaction of a client for a beginner counselor's question is important to visualize...
Acquisition of parameters for the Bidirectional Scattering Surface Reflectance Distribution Function (BSSRDF) has significant meanings in the study of computer graphics and vision research field. In this paper, we present an inverse rendering approach combined with a newly developed BSSRDF model, directional dipole model, for parameter estimation. To validate our algorithm, we estimate parameters...
In this paper, we present a method to evaluate earthenware having a rotational shape by using ellipses. The rotational shape is a typical shape that is encountered in the archeological study of earthenware. The distortion in this shape differs according to the habits and methods of the craftsman. Through calculating the degree of the circularity of the cross sections of a model, the distortion in...
This paper presents our novel algorithm for decoration points' segmentation with simple calculation in a two-dimensional domain. Our algorithm works for unorganized point clouds. It extracts the relationship between two adjacent sub-regions, which are derived from a single cross section of the point cloud. The cutting planes are defined by the Frenet frame of curve skeleton. In our method, angle-based...
In this paper, we propose an assembly navigation operation using a 2-D panel that takes into account flow patterns and outline information. The aim is to realize an efficient search for adjacent fragments using a fracture restoration interface. In this method, a point cloud representing the surface of the earthenware fragments is measured first by a 3-D measurement device. Then, the obtained data...
