  • Patent number: 7152016
    Abstract: There is disclosed an apparatus for supporting evaluation of usability in consideration of situations particular to each business and ISO evaluation standards. The usability evaluation support apparatus uses an instrument including a display portion for displaying information, and supports the evaluation of usability in achieving a given task. During achievement of the task, a control unit acquires information of an operation log related to an operation performed by a user, and divides an effectiveness index associated with achievement of the task, efficiency index associated with efficiency for the achievement, and satisfaction index associated with subjective satisfaction of a task achiever for each predefined subtask. The unit evaluates the indexes by a statistical calculation using measurement results of a plurality of measurement items including the information of the operation log for each subtask.

  • Patent number: 6657614
    Abstract: The present invention provides a detection apparatus, an input apparatus, an individual identification apparatus, and a recording medium that utilize information about users' bodies which disables the fraud of impersonating authorized users and is extremely difficult to forge and is obtained without giving the users a sense of inhibitions, without restraining their bodies during use, and independent of their mental states and health. A FIFO memory outputs, as one set of features, a total of 60 voltage values, which are broken down as 20 voltage values sampled every 12.5 ms (80 Hz) before the instant when timing is inputted at the peak position of an amplitude waveform signal generated by one click operation, 39 voltage values sampled every 12.

  • Patent number: 6603867
    Abstract: A three-dimensional object identifying system is disclosed which identifies a three-dimensional shape object optically such as a part of a human body for preventing an information apparatus such as a personal computer from being used by any other illegitimate user than a legitimate user. The three-dimensional object identifying system has a function generating unit which generates modulation signals, light emitting elements which emit lights based on the modulation signals to a three-dimensional object, light receiving elements which receive reflected lights from the three-dimensional object and which produce detection signals, a correlation detecting unit which detects correlation information between each detection signal and modulation signal, and an identifying unit which performs identifying processing for the three-dimensional object on the basis of both pre-cataloged correlation information and the detected correlation information.
