  • Patent number: 10488928
    Abstract: A tactile sensation providing system includes an electronic device and a tactile sensation providing apparatus, which includes a wearable part worn on fingers, vibrating elements disposed at portions corresponding to the fingers, sensors that detect touches of the fingers onto a manipulation input surface, and a second controlling part able to communicate with a first controlling part. Upon receiving from the second controlling part a signal representing that a touch of one finger is detected by one sensor, the first controlling part obtains, based on data representing the finger and on coordinates detected by a detector, a type of the finger touching the surface and the coordinates where the finger touches the surface, and generates a driving signal representing a tactile sensation corresponding to the data representing the finger, the coordinates, and a displayed image. The second controlling part drives one of the vibrating elements using the driving signal.

  • Publication number: 20160058393
    Abstract: A sensor part has sensor cells provided in a matrix arrangement on a sensor that detects a pulse within a region in which the pulse of a diagnostic target is detected, in a state in which a pressure is applied to the region through the sensor. A diagnostic apparatus acquires a distribution of a pulse waveform based on the pulse detected in a state in which the pressure is constant, determines observation positions within the region, and determines a maximum amplitude at the observation positions that are determined by increasing the pressure, based on the distribution of the pulse waveform. A digitized score of the pulse at each observation position is computed based on the pressure at a time when the pulse waveform having the maximum amplitude is obtained at each observation position.
