  • Publication number: 20230388732
    Abstract: The present technology relates to an information processing apparatus, an information processing method, and a program capable of reproducing a sound pressure of a playback sound in a measurement environment. An information processing apparatus according to one aspect of the present technology records sound pressure reproduction data used to reproduce sound pressure of a speaker as a sound pressure when outputting a playback sound obtained by playback processing using transfer characteristics of sound in a measurement environment where the speaker is installed from an output apparatus prepared in a playback environment together with transfer characteristic data representing the transfer characteristics. The present technology can be applied to a system that performs audio mixing of contents such as movies.

  • Patent number: 9310265
    Abstract: A tactile sensor and a multi-axial tactile sensor are provided, each of which is thin and can measure shearing force. A multi-axial tactile sensor 1 includes a sensor element 2 provided in a plane substantially at the same level as the surface of a substrate 6, and an outer package member 42 covering around the sensor element 2 and transmitting external force to the sensor element 2. The sensor element 2 includes a flexible beam 7 (8) having at least one end supported by the substrate 6. The sensor element 2 detects deformation of the beam 7 (8), the deformation being caused in the direction in parallel with the surface of the substrate 6.
