Abstract: PROBLEM TO BE SOLVED: To increase convenience of a user visiting an island in a virtual space.
SOLUTION: In the virtual space comprising a plurality of islands, positions of the islands are two-dimensionally mapped preferably by multidimensional scaling such as Kruskal's method such that the relation of distance between a characteristic vector including information on a profile, taste or the like of the user and a characteristic vector including information on a profile, an event or the like of each island is maintained. Thus, a map server provides the user with the islands arranged in accordance with the characteristic vector of the user based on mapped information. Thereby, it is convenient for the user to visit the island suited to his or her taste, so that a use frequency of the virtual space is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a method in which background noise other than the sound source located along an objective direction is efficiently eliminated to realize highly precise voice recognition and to provide a system using the method.
SOLUTION: An angle distinctive power distribution, that is observed by orienting the directivity of a microphone array toward various sound source directions being considered, is approximated by the sum of coefficient multiples of a reference angle distinctive power distribution that is beforehand measured using reference sound along the objective sound source directions and a reference angle distinctive power distribution of non-directive background sound. Using the above fact in a noise suppressing process section, only the components along the objective sound source direction are extracted. Moreover, when the objective sound source direction is unknown, the objective sound source direction is estimated by selecting the one which minimizes an approximation residue in a sound source location searching section among the reference angle distinctive power distributions along various sound source directions. Furthermore, a maximum liklihood operation is conducted using the voice data of the components along the sound source direction being processed and the voice model which is obtained by making a prescribed model for the voice data and voice recognition is conducted based on the obtained estimated value.

Abstract: PROBLEM TO BE SOLVED: To improve the operability of a computer device in moving a display window of a software keyboard, etc. SOLUTION: Whether a user pointed a button for moving the software keyboard or not is determined (Step S5). When it is determined that the user pointed the button, the quantity of movement of the display window of the software keyboard is calculated based on the pointed position (touched position) within the pressed button for movement (Step S15). Then, based on the calculated quantity of movement, the position of the display window on the display screen is moved (Step S17).

Abstract: PROBLEM TO BE SOLVED: To reduce the swapping of buffer data by absorbing the speed difference between the writing and reading of external received data to and from a buffer. SOLUTION: Ring buffer constitution is adopted and the buffer consists of 'subrings' as minimum units of buffer rings and a 'main ring' connecting the subrings in a ring shape. While data processes are carried out synchronously, only a single subring is used for data buffering and only when the data processes are delayed to become asynchronous, a main ring buffer covering more than one subring is used. Namely, the possibility of the use of the whole main ring can be minimized, so swapping is prevented suitably from being always done.
