Abstract: A method and a device for locating an optical fiber buried in a volume. More particularly, the method includes at least: determining a position of the optical fiber, based on at least one detection level of a source of radiation for at least one position of the source, provided by a detection device connected to the optical fiber.

Abstract: A method and a device for characterizing a user, in particular a user of a device and/or a service in the field of computer security. The characterization method includes: a comparison of first data associated with a first sound object spatialized at a first location by a user interface of a communication terminal and second data received following the reproduction of the first spatialized sound object, the second data being based on a second spatialized sound object perceived at a second location. The comparison triggers, in the event of a positive result, a characterization of the source of interaction as being a suitable user. Thus, errors in characterizing a user as a suitable user, in particular a human user, are reduced because existing sound and speech recognition systems are not able to select a sound in a spatialized sound environment, i.e. a 3D audio scene.

Abstract: A method for characterizing a user and a corresponding computer program, storage medium, and processing device. The method includes comparing between at least one first identifier of a first sound and at least one second identifier received from a human-machine interface, after the human-machine interface plays a plurality of second sounds, which are heard by the user. If the at least one second identifier received corresponds to the first identifier, the comparison triggers a characterization of the user as being a suitable user.

Abstract: Methods and systems are described which relate to the assistance or guidance of a user in the detection of an element in an area. A search assistant for searching for an element in an area may include a direction changer for changing the direction of emission of a visible signal on the basis of detected relative data of an element sought in the area, the relative data detected by at least one sensor such as an audio sensor or a video sensor. Such a search assistant may use a simple visible signal for guidance toward the element sought in the area. The technology used may be easy to implement, cheap and readily accessible, allowing guidance precision that depends solely on the precision of the known or detected location of the sought object.

Abstract: Methods are described of monitoring or supervising objects, particularly non-communicating objects. A detector for detecting complex states of objects is described, the detector comprising an analyzer configured to determine an object-related complex state depending on recognition of a least one sound emitted by the object. The recognized sound allows the detector to determine the complex state of an object. This complex state of the object may include an abnormal operating state of the object or a state of the object that is not related to its operation. For example, the complex state of the object may include its position on a surface, in a volume, or the identity of the person having handled the object.

Abstract: An electronic device for performing environmental analysis, in particular a sound-analyzing object for voice assistance. The electronic device includes: a system for monitoring an environment in which the device is placed, and a visual physical indicator which is controlled depending on at least one command parameter delivered by the monitoring system. Thus, the user of the electronic device is able to perceive the object of attention of the monitoring system since the monitoring system provides feedback by using one or more visual indicators that the monitoring system commands.

Abstract: A pressure button for a touch-sensitive surface, a physical interface for a touch-sensitive surface, and a protection element for a touch-sensitive surface, in particular a touch screen of a terminal such as a smart phone or a tablet. The pressure button has a contact switch passing through the pressure button, from the upper surface to the lower surface of said pressure button. The contact switch is suitable for allowing interaction with a terminal via a touch-sensitive surface when the pressure button is positioned on the latter. The user can thus interact with the terminal by using a pressure button without requiring connectors for this interface.

Abstract: Objects are provided that can be manipulated relative to a touch-sensitive surface, in particular game pieces or buttons for interacting with a touch screen. A manipulable includes at least one lug enabling an interaction with the touch-sensitive surface; and a slot suitable for inserting the manipulable object on a holder that can be positioned relative to the touch-sensitive surface. The placement of the slot over the height of the manipulable object is suitable for keeping the at least one lug of the manipulable object in interaction with the touch-sensitive surface. Thus, the manipulable object allows the touch-sensitive surface to be interacted with at any time without any interaction errors, regardless of the position of this touch-sensitive surface relative to the horizontal. The touch-sensitive surface identifies any interaction (at a point or sliding) of the manipulable object and a non-erroneous location of this interaction on the tactile surface.
