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. In specific embodiments, a calibration routine and/or a compensation routine of latency of the processing device may be performed in real time.

A graphical user interface supporting eye tracking is enriched with graphical representations of the degree of attention afforded respective areas of the user interface. These representations may comprise heatmaps, visual variable and the like. The generation of these representations may furthermore be used to adjust other user interface behaviour, for example by repositioning a mouse cursor to a part of the screen afforded greater protection. The attention information of a plurality of users may be compiled together and used to modify the graphical representation, providing each user with an indication of the focus of attention of their colleagues, thereby establishing a group awareness.

A zoom operation in an eye tracking based graphical user interface, where the zoom operation, as initiated by a scroll wheel etc. takes place with respect to the focus of the users attention as determined on the basis of eye tracking data. Mechanisms for determining the point of attention based on a sliding window recording point of regard and subject to a variety of weighting functions are proposed.

An interaction mechanism is defined for the navigation of a representation of a physical space, whereby events or entities of interest outside the current view are detected, and flagged by adding a visual indicator at or near the edge of the view closest to the entity in question. By designating the visual indicator, for example with a mouse click or by directing the users gaze at the visual indicator, the representation is prompted to modify the representation to include the space incorporating the entity of interest. The point of view may revert to the initial point of view on a further user action or after a predetermined time, or the original point of view may be flagged as a new entity of interest which the user may then select. Multiple points of interest may be defined such that the user may jump from point to point.

The invention relates to the verification of properties of an interactive component having a recursive tree structure of subcomponents. The verification comprises creating an oriented graph from the tree, said oriented graph comprising arcs for the child relationships of the tree, and arcs for couplings creating upon couplings between the components. The verification comprises creating a second graph representative of the property, and verifying if the second graph is exhibited within the first oriented graph.

The invention discloses a vehicle management system which is energy centric. The system may be configured to operate on a terrestrial vehicle, a nautical or on an aerial vehicle. It is configured to allow a user input a route comprising legs, each leg associated with an activity and an energy consumption mode. The system captures parameters from sensors to compute a position of the vehicle and a predicted energy consumption per leg. The system comprises a display unit which associates graphically the activities and their energy consumptions. It allows the user to simulate what if scenarios, to visualize the impact of modifications of some of the parameters of energy consumption on an energy/time/range budget.

The invention relates to the development, control and execution of interactive software. An interactive component of the invention is configured to enable a defined interaction between the interactive digital system and an environment of the interactive digital system .It comprises a first subcomponent, defining a coupling between a second interactive component and a third interactive component. Said first subcomponent is configured, when executed by the interactive digital system, to generate an activation of the third interactive component conditional upon an activation of the second interactive component, said activation enabling the defined interaction.
