This paper describes the design and implementation of MAJIC, a multi-party videoconferencing system that projects life-size video images of participants onto a large curved screen as if users in various locations are attending a meeting together and sitting around a table. MAJIC also supports multiple eye contact among the participants and awareness of the(More)
TCP Reno congestion control carries two issues. First, its performance is poor in high-speed networks. To solve this TCP Reno drawback, HighSpeed TCP and Scalable TCP were proposed. However, the fairness between these proposed TCP and TCP Reno is not considered , when both connections coexist. Second, TCP Reno connections share bandwidth unfairly, when TCP(More)
Dopamine, acetylcholine, and serotonin, the main modulators of the central nervous system, have been proposed to play important roles in the execution of movement, control of several forms of attentional behavior, and reinforcement learning. While the response pattern of midbrain dopaminergic neurons and its specific role in reinforcement learning have been(More)
This paper proposes a model for calculating statistical gate-delayvariation caused by intra-chip and inter-chip variability. As thevariation of individual gate delays directly influences the circuit-delayvariation, it is important to characterize each gate-delay variationaccurately. Furthermore, as every transistor in a gate affectsthe transient(More)
This paper proposes a new technique to visualize dependencies among cells in a spreadsheet. In this way, the system firstly visualizes a spreadsheet on a plane in three-dimensional space, and draws arcs between interrelated cells. By allowing a user to select an arbitrary cell and lift it up with direct manipulation, the system utilizes the third dimension(More)
In this paper, we propose to direct the visual image of a videoconferencing system. Pictures of current videoconferencing systems are often boring. We thought presentation of pictures on TV and in movies should be studied to improve videoconferencing. For this purpose, we investigated several debate programs on TV. We classified all the shots into eight(More)
Trials on the transmission of olfactory information together with audio/visual information are currently being conducted in the field of multimedia. However, continuous emission of a scent creates problems of human adaptation to the lingering olfactory stimuli. During long movie scenes, viewers can not detect an emitted scent continuously. To overcome this(More)
