A position indicated by a user with a finger or a stylus can be detected even in a case where an edge of a hand on a little finger side or a wrist touches a touch panel. An input device acquires information indicating a plurality of points on a touch panel affected by a user's touch, including the touch with a finger or a stylus, calculates distances between a reference position and at least some of the plurality of points, the reference position indicating a position touched by the user on the touch panel other than with the finger or the stylus, selects one or more points affected by the touch with the finger or the stylus from the at least some of the plurality of points based on the calculated distances, and acquires coordinates of a position indicated by the user based on the selected point.

Input device, input method and program

An information display device that includes circuitry that receives specification of an annotation position indicating a position of an annotation in display information to be displayed on a display; when specification of the annotation position is received, generates an annotation code corresponding to the annotation position, and stores the generated annotation code in association with the annotation position into a memory; outputs the generated annotation code in a format recognizable to an operator; receives input of annotation information containing at least the annotation code and representing the annotation; and performs control so that, when the annotation code contained in the received annotation information matches the annotation code stored in the memory, the annotation information is output at the position in the display information indicated by the annotation position corresponding to the annotation code.

Under a preliminary environment, test searches with a current algorithm and a new algorithm are performed. Based on evaluation values related to rankings of the searches calculated based on these results, a first evaluation value for the current algorithm and a second evaluation value for the new algorithm are acquired. A control is performed to present relative evaluation information of the new algorithm with respect to the current algorithm based on these first evaluation value and second evaluation value. The evaluation values related to the rankings are calculated based on relevance corresponding information. In the relevance corresponding information, a relevance score is made to correspond to a test query of a test content data item for each set of the test query and the test content data item related to this test query.

Information processing device, information processing method, program and storage medium

A position indicated by a user with a finger or a stylus can be detected even in a case where an edge of a hand on a little finger side, a wrist or the like touches a touch panel. An input device acquires a touch intensity change signal that indicates a change of touch intensity at a plurality of measuring positions on a touch panel, applies a frequency filter, which suppresses a frequency component of the touch intensity change signal generated by a touch other than by a finger or a stylus, to the touch intensity change signal at at least one of the measuring positions, and generates data of a position indicated by a user on the touch panel based on the touch intensity change signal, to which the frequency filter is applied, at the respective measuring positions.

A power-supply control device includes a high-frequency component detecting unit, a machining voltage level detecting device, a no-load time detecting device, and a pulse control device. The high-frequency component detecting unit detects a high-frequency component of discharge voltage at a machining gap. The machining voltage level detecting device detects a discharge voltage level at the machining gap. The no-load time detecting device detects delay time of discharge of the discharge voltage at the machining gap. The high-frequency component is compared with a reference value to obtain a first comparison result. The discharge voltage level is compared with a reference level to obtain a second comparison result. The pulse control device controls pulse off time based on the first comparison result and the detected delay time, and cuts off a discharge pulse based on the second comparison result.

A discharge pulse control device cuts off a pulse width of the a discharge pulse being produced in a machining gap when a comparison result of a voltage level comparator indicates abnormal electrical discharge. Upon detection of abnormal electrical discharge based on comparison results of a high-frequency component comparator and the voltage level comparator, a quiescent period control unit constructed from a discharge pulse diagnosis device, a first pulse counter, a second pulse counter, and a quiescent pulse control device performs change setting of the quiescent period at the time of occurrence of abnormal electrical discharge and sends that information to the discharge pulse control device. Subsequently, the discharge pulse control device performs change control of the quiescent period at the time of occurrence of abnormal electrical discharge so that the discharge pulse and the quiescent time are optimally controlled.
