This paper introduces the design and functions of HTIP (Home network Topology Identifying Protocol), which can identify the home network topology and check the connectivity to end devices and/or network devices. Applications can utilize this information to perform the rapid, high-resolution fault localization needed if network services are not provided(More)
We present the migratory cursor, which is an interactive interface that enables users to move a cursor to any desired position quickly and accurately using voice alone. The migratory cursor combines discrete specification that allows a user to specify a location quickly, but approximately, with continuous specification that allows the user to specify a(More)
We develop an interactive Braille-recognition system using a portable camera for visually impaired persons who cannot read Braille. Our system helps them to find and then push a desired button, as is necessary when using an elevator or a ticket vending machine, for example. It is natural to think that the information provided, in Braille, with specific(More)
We propose a speech-operated cursor that is easy to move to any desired position. Speech-recognition systems are useful for people with physical disabilities, because such systems allow them to manipulate a computer using voice only. However, using traditional speech-recognition systems it is difficult to move the cursor to a desired position. To make it(More)
In this article, we propose a method to identify the link layer home network topology, motivated by applications to cost reduction of support centers. If the topology of home networks can be identified automatically and efficiently, it is easier for operators of support centers to identify fault points. We use MAC address forwarding tables (AFTs) which can(More)
The purpose of this study was to evaluate the radiation dose reduction to patients and radiologists in computed tomography (CT) guided examinations for the thoracic region using CT fluoroscopy. Image quality evaluation of the real-time filtered back-projection (RT-FBP) images and the real-time adaptive iterative dose reduction (RT-AIDR) images was carried(More)
