We propose a grid-pattern indicating interface to provide instructions remotely from remote site to support independent daily life of senior citizens. Our aim is to realize smooth and easy telecommunication between supported ...
This paper reports an evaluation experiment using our prototype system which dynamically projects ruled lines on a sheet of paper to support a user in layout design. The system projects lines at proper positions depending ...

In this paper, we try to apply an approach of XML element retrieval to 1CLICK-2. The aim of XML element retrieval is to identify key points in structured documents, and propose them to system users. We believe that the aim ...
Passive eye-pose estimation methods that recover the eye-pose from natural images generally suffer from low accuracy, the result of a static eye model, and the recovery of the eye model from the estimated iris contour. ...
Fingerprinting requires sensor data map to estimate a user’s location by comparing the map with sensor data of the user’s device. Although it is assumed that the sensor data does not change, it is considered that the premise ...
In this paper, we investigated the method of counting the number of people getting on/off the bus. As a result, there are currently research and products that estimate the number of people getting on/off using dedicated ...
In recent years, the protection of personal information has drawn much attention, requiring an advanced technology on de-identification to remove personal information from data. Among various personal information such as ...
Sophisticated data science techniques have recently been applied to social networks data to study social phenomena and people. Recognizing that social psychology research has witnessed a renewed interest in the notion of ...

This paper investigates receive power control for multiuser inductive power transfer (IPT) systems with a single-frequency coil array. The primary task is to optimize the transmit coil currents to minimize the total input ...
We present a method to estimate the cost of mental (hand) simulation of programs. In mental simulation, human short term memory is extensively used to recall and memorize values of variables. When the simulation reaches a ...
In this paper, we present a new method to protect software against illegal acts of hacking. The key idea is to add a mechanism of self-modifying codes to the original program, so that the original program becomes hard to ...
In the next-generation home network systems (HNS), interoperability among multi-vendor appliances is a challenging issue to implement value-added integrated services. This paper presents a service-oriented framework to ...
Java programs distributed through the Internet are now suffering from program theft. This is because Java programs can be easily decomposed into reusable class files and even decompiled into source code by program users. ...
In software development, software reuse has become a pivotal factor in creating and providing high-quality software at a reduced cost. The reuse of a code creates dependencies, which as they increase over time become ...
This paper describes an empirical study to reveal rules associated with defect correction effort. We defined defect correction effort as a quantitative (ratio scale) variable, and extended conventional (nominal scale based) ...
The goal of this paper is to improve the prediction performance of fault-prone module prediction models (fault-proneness models) by employing over/under sampling methods, which are preprocessing procedures for a fit dataset. ...

Bug fixing accounts for a large amount of the software maintenance resources. Generally, bugs are reported, fixed, verified and closed. However, in some cases bugs have to be re-opened. Re-opened bugs increase maintenance ...
