105 results about "Visual cueing" patented technology

Visual cueing. A visual cue is a signal which your brain extracts from what you see. It indicates the state of some property around you that you are interested in perceiving. Now, only 1% of what you see actually enters through your eyes (the rest is -surprisingly correct – made up by your brain).

Method and system for predicting ship motion or the like to assist in helicopter landing

A method for a short-term prediction of future ship motion in open water to furnish visual cueing information that can be remotely presented to a pilot during an aircraft landing is described. Two sets of samples of the sea surface geometry along a radial azimuth line from a ship as a function of elevation of a sensor are first acquired. These are compensated to remove the components due to the ship's motion. Two wave traces are then separately derived in Cartesian format from the two sets of acquired samples. These wave traces are subjected to a Fast Fourier Transform to detect the amplitudes and phases of the individual wavelength components. The direction of the wavelength components is determined using a measure of their phase change in the scan direction during the time interval between the two scans together with their measured wavelength. The amplitude, direction and phase of each component is utilized together with the known motion characteristics of the moving ship in order to derive a short-term prediction of future ship motion in the time domain. A quiescent period of the ship motion is located by comparing the short-term prediction with the pre-defined operating limit criteria. Finally, a message signal is transmitted to the pilot of the aircraft indicating Time-to-Land and the duration of the quiescent period.

Proximity-triggered handrail cueing system with automatic attention capture

The present invention provides a proximity-triggered handrail cueing system with automatic attention capture for providing visual and auditory cues that automatically and involuntarily (subconsciously) attract attention to the handrail. The system includes a hand railing (i.e. handrail or grab bar) constructed from translucent or transparent plastic tubing, a series of lights mounted inside the railing, along the longitudinal axis, one or more auditory speakers built into the railing or railing brackets, and a proximity detector (e.g. photoelectric sensor) and controller that activates the lights and speakers whenever a person approaches the railing. The speakers can be used to issue a verbal prompt to hold the handrail. The lights inside the railing are triggered to suddenly start flashing in such a way as to automatically and subconsciously attract attention to the handrail, thereby facilitating ability to rapidly and effectively reach and grasp the handrail for support in the event that the person does not hold the railing voluntarily and subsequently experiences a sudden unexpected loss of balance. Sounds emitted by the speakers can also be used to improve the ability to rapidly grab the railing in response to loss of balance. Embodiments of the system may include: 1) a proximity-triggered handrail cueing system with automatic attention capture elicited by visual cueing, 2) a proximity-triggered handrail cueing system with automatic attention capture elicited by auditory cueing; and 3) a proximity-triggered handrail cueing system with automatic attention capture elicited by a combination of visual and auditory cueing.
