This paper discusses the effects of a visual interface for the Japanese hand language system. The system <i>Practice! Yubimoji AIUEO (PYA)</i> we are developing aims at letting ordinary pupils learn basic character expressions (AIUEO) of the Japanese hand characters (Yubimoji). Because very few pupils in Japan are currently able to communicate with(More)
Knowing where people look when viewing faces provides an objective measure into the part of information entering the visual system as well as into the cognitive strategy involved in facial perception. In the present study, we recorded the eye movements of 20 congenitally deaf (10 male and 10 female) and 23 (11 male and 12 female) normal-hearing Japanese(More)
In this study, we developed a simulation game called "Human SUGOROKU" that consists of a full-body interaction system to enable elementary school students to enjoy and learn vegetation succession. The students' sense of immersion is improved by enabling them to play this game using their body movements. We conducted an experiment with the students and(More)
In general living environments, in order to separate children's voices from backgrounds noise, we developed a sound separation system by a microphone array. We created a game by use of this developed system, and conducted evaluation experiment intended for elementary school children. As a result, we confirmed this system could separate 3 voices, and the(More)
The purpose of this paper is to report a case study involving the successful redesigning of a Web page that was problematic for the hard-of-hearing. We found in our previous eye-tracking studies [1,2,3] that the page in question presented serious usability problems for the hard-of-hearing. Namely, the performance of hard-of-hearing participants was inferior(More)
When ordinary people learn hand languages, it is critical to properly understand that the forms of the hand shapes and moves are different for speakers and listeners. To cope with the issue, we have equipped a PC camera with the visual interface of an edutainment system for Japanese hand alphabets. To investigate the visual interface, we have conducted(More)
—This paper presents a spherical microphone array design which can be used for capturing a sound selectivity and locally. Capturing a sound by microphone array is achieved by method of Delay and Sum Beam Forming (DSBF). In this method, microphone arrangement has a large effect on the directivity. Using beamforming simulation, the authors investigated on the(More)
This paper reports two experiments conducted to investigate the utility of pictograms for improving usability of web pages for hard-of-hearing persons. The first experiment simulated a directory-based information search task, typically carried out at portal sites, to understand how the task is performed when directories are represented in text form.
