Typically, practitioners of the KJ method use paper labels and four-colored ball-point pens to externalize their thoughts and ideas during the process. A similar approach and method is used in group KJ lessons. However, due to the large paper size required, this approach is limited in effective capturing and sharing of outcomes. Considering the merits of(More)
We developed AirTransNote, a computer-mediated classroom collaboration system. The system enables real-time note-sharing. AirTransNote manages notes written by students on paper and enables the teacher to browse through the notes or show them to the students. AirTransNote can analyze students' answers, helping the teacher better understand their problems.(More)
This paper introduces our design of " AirTransNote, " a computer-mediated learning system that employs digital pen devices to minimize student's exertion in classrooms. But although the design frees students from PC operation the teachers still have to handle their PC during their lectures. We have enhanced the system by introducing an RFID technique in(More)
We developed AirTransNote, an interactive learning system augmented by digital pens and PDAs for each student. All notes written on regular paper sheets are immediately digitized and transmitted to teacher's PC and recognized to generate feedback. Also since the students' drawings can be projected on a screen, our system helps students to recall their(More)
SUMMARY Practitioners of the Jiro Kawakita (KJ) method, a method for organizing ideas, typically use paper labels and four-colored ball-point pens to record their ideas during the creative thinking process. A similar approach is used in group KJ method sessions; however, the effectiveness of capturing and sharing the diagrams and information is limited(More)
Conventional tabletop systems have focused on communication with virtual data, using phicons or physical objects as handles. This approach is versatile, given the full use of a horizontal display. However, we consider that an another approach can be formulated that can support normal specific tasks on a table. We have developed a card-handling activity(More)
— We have been developing an RFID (radio frequency identification) mat system to assist caregivers in a group home. In Japan, the number of group homes offering home-like care for elderly persons suffering from dementia has increased considerably. Even though the smaller number of people residing in a group home makes it suitable for family-like care, the(More)
We have developed a menu-selection-based Japanese input method for a pen device. To obtain user-input kanji-form text rapidly, the system requires sequence of consonant. Following this, the user selects kanji-form candidates inferred by the system. In some situations, consonant sequences can trigger an explosion of kanji-form candidates. Therefore, we have(More)
Classrooms for computer-related courses are intrinsically larger than regular lecture rooms because of the existence of installed PCs as well as network and outlet facilities. Some of the previous studies have investigated the effect of students' seat location on their performance, particularly for large class sizes. In this study we examined the effect of(More)
