Method for assisting a person in acting in a dynamic environment and corresponding system
First Claim
1. A method for assisting a person in assessing a dynamic environment, comprising steps of:
- obtaining information on states of at least two entities in a common environment;
predicting a future behavior of each of the entities based on the obtained information and at least one event involving the at least two entities;
estimating a time to event for the at least one predicted event involving the at least two entities and a position of occurrence of the at least one predicted event relative to the person or to a predetermined entity associated with the person; and
generating a signal for driving an actuator indicative of a relative direction of the predicted event with respect to the person and indicative of the time to event, the signal causing a stimulation being perceivable by the person by its perceptual capabilities,wherein the stimulation is a stimulation signal causing the stimulation of the person at a dedicated location of the person'"'"'s body to encode the relative direction, andone or more parameters of the stimulation signal encode the time to event such that the signal'"'"'s saliency is higher the smaller the time to event is.

Abstract
The invention regards a method and a system for assisting a person in acting in a dynamic environment. At first, information on states at least two entities in a common environment is obtained. A future behaviour of each of the entities is then predicted based on the obtained information and a time to event for at least one predetermined event involving the at least two entities and a position of occurrence of the event relative to the person is estimated. Then, a signal indicative of the relative direction of the predicted event with respect to the person and indicative of the time to event for driving an actuator is generated, the signal causing a stimulation being perceivable by the person by its perceptual capabilities, wherein the time to event is encoded such that the signal'"'"'s saliency is the higher the smaller the time to event is.

11. A system for assisting a person in assessing a dynamic environment, the system comprising:
-
a state information obtaining unit for obtaining information on states of at least two entities in a common environment; processor for predicting a future behavior of each of the entities based on the obtained information, for predicting at least one event involving the at least two entities, and for estimating a time to event for the at least one predicted event and a position of occurrence of the at least one predicted event relative to the person; and signal generator for generating a signal indicative of the relative direction of the event with respect to the person and indicative of the time to event, the signal causing an actuator to stimulate the person such that the stimulation is perceivable by the person using its perceptual capabilities, wherein the signal is a stimulation signal causing the stimulation of the person at a dedicated location of the person'"'"'s body to encode the relative direction, and one or more parameters of the stimulation signal encode the time to event, wherein the time to event being encoded such that the signal'"'"'s saliency is higher the smaller the time to event is. - View Dependent Claims (12, 13)
