Abstract: A user moves a cursor on a display of an operation terminal on the basis of a pressure change in X-axis and Y-axis directions, and performs a tap operation on the display on the basis of a pressure change in a Z-axis direction. However, in a case where the user performs a tap operation, not only a pressure in the X-axis and Y-axis directions but also a pressure in the Z-axis direction is applied, and erroneous measurement of a tap operation may occur.
Therefore, an operation terminal 1 measures a first pressure value indicating a pressure in a first parallel direction with respect to a touch surface of a touch sensor such as a touch panel, a second pressure value indicating a pressure in a second parallel direction with respect to the touch surface, and a third pressure value indicating a pressure in a vertical direction with respect to the touch surface, measures a predetermined pressure duration indicating a time during which the third pressure value continues to be within a predetermined pressure value range, and determines that an operation on the touch sensor is a tap operation in a case where the predetermined pressure duration is equal to or less than a predetermined time or is less than a predetermined time and a maximum value of the first pressure value and a maximum value of the second pressure value measured within the predetermined pressure duration are equal to or smaller than a predetermined value or are smaller than a predetermined value.-

Abstract: According to one aspect of this invention, upon estimating a contact state or a state of an object when a sensing unit is brought into contact with the object, a sensor device in which a first piezoelectric element and a second piezoelectric element are integrally configured in a state of being overlapped with each other is provided in the sensing unit. Then, an acoustic interface unit drives the first piezoelectric element to transmit a first sound wave and detects a reception signal corresponding to a second sound wave received by the second piezoelectric element in response to the transmission of the first sound wave, and an estimation device extracts a frequency feature amount from the reception signal and estimates a contact state of the sensing unit with the object or a state of the object on the basis of the extracted frequency feature amount.

Abstract: A time-variant noise spatial covariance matrix is estimated effectively. Using time-frequency-divided observation signals based on observation signals acquired by collecting acoustic signals emitted from one or a plurality of sound sources and mask information expressing the occupancy probability of a component of each of the time-frequency-divided observation signals that corresponds to each noise source, a time-independent first noise spatial covariance matrix corresponding to the time-frequency-divided observation signals and the mask information belonging to a long time interval is acquired for each noise source. Further, using the mask information of each of a plurality of different short time intervals, a mixture weight corresponding to each noise source in each short time interval is acquired. Furthermore, a time-variant third noise spatial covariance matrix is acquired, the third noise spatial covariance matrix being based on a time-variant second noise spatial covariance matrix, which corresponds to the time-frequency-divided observation signals and the mask information belonging to each short time interval and relates to noise formed by adding together all of the noise sources, and a weighted sum of the first noise spatial covariance matrices with the mixture weights of the respective short time intervals.
