Abstract: A computerised device comprises an man-machine input interface (4), a controller (6) and a display (10), the controller (6) being arranged to control the display (10) according to a control value measured on the man-machine input interface (4) at a first measuring frequency.

Abstract: The invention discloses a method to measure end-to-end and partial latency between an input interface and an output interface of a processing device. The invention uses a generator of a calibrated output to be output by the processing device through the output interface and a sensor configured to capture the calibrated output and send it to a processing unit of the processing device through the input interface. An advantageous arrangement of a calibrated output is a specific texture to be output by a screen and captured by an optical sensor. A specific texture comprises elementary patterns which have a defined number of pixels and a defined proportion and location of dark and light pixels. According to certain aspects of the invention, a calibration of latency is performed based on a number of parameters defining the hardware and/or software configuration of the processing device, and/or its conditions of operation.

Abstract: A system (10) for displaying at least one virtual object includes a secondary screen (20) for displaying the virtual object, a primary screen (30), an optical element for overlaying images displayed on the secondary screen (20) with images displayed on the primary screen (30), and a pointing surface combined with the primary screen (30) for detecting the contact of one or more physical pointing elements. A device (90) for manipulating at least one virtual object includes calculation elements for generating images of the virtual object displayed on the system (10) from information output from the system (10) in accordance with the actions of the operator (100).

Abstract: A ground-based haptic interface equipped with at least two decoupled rotary finger actuators adapted to be manipulated with the fingertips of a single hand of a user. For each finger actuator, a means are included for measuring the angular position of the actuator or for measuring the torque applied on the axis of rotation of the actuator. Each rotary finger actuator is associated with a control motor adapted to apply, on the axis of rotation of the actuator, a torque that is a function of the angular position of the actuator, or that controls the rotational position of the axis of rotation of the actuator as a function of the torque applied on this axis. The haptic interface can be used as a peripheral of a computer, for example, for interacting with a virtual environment. It can also be applied to the control or manipulation of real objects by being coupled, for example, with a robot or a manipulating arm. The interface also can be telemanipulated.

Abstract: The input device (1) comprises a touch-sensitive surface (10a) forming at least one isotonic input area and elastic abutment means (11) forming at least one passive elastic input area that is adjacent to the isotonic input area. A position control is performed in the isotonic input area and a rate control is performed in the elastic area.

Abstract: The absolute input device with passive force feedback comprises a mobile end-effector (5) in a work area that is divided into at least two distinct adjacent areas: one isotonic area (I) and one passive elastic area (E).
