Methods for gradually exposing a subject to a fear comprising: adapting a virtual reality scenario to expose the subject to the fear by gradually transforming one or more of objects from a first state to a second state, the second state of the object provoking an increase of the fear, and wherein the transforming one or more of the objects take place only if the following two conditions are fulfilled: a time condition specifying an amount of time from the previous increase of fear, and the object is in a peripheral field of vision of the subject as derived from the orientation of the head mounted device. A computer program and computing systems for gradually exposing a subject to a fear are also disclosed.

Methods and systems for gradual exposure to a fear

Methods for provoking a physiological response in a subject comprising: receiving from sensors an orientation of an HMD of the subject and a parameter indicative of a physiological state of the subject, determining a video signal representing an avatar of the subject in a virtual reality scenario to be displayed on the head mounted display taking into account the orientation of the head mounted display, wherein the video signal includes an indication of a physiological state of the avatar, and sending the video signal to the head mounted display for visualization, optionally accompanied by a suitable audio signal. During a first period, the indication of the physiological state of the avatar substantially corresponds to the measured physiological state, and during a second period the indication of the physiological state of the avatar does not correspond to the measured physiological state. Related computer program and computing systems are also disclosed.

Physiological response

A method for motor training comprising: receiving from one or more sensors an orientation of a head mounted display of the subject; adapting a base video signal representing an avatar of the subject in a virtual reality to be displayed on the head mounted display wherein the avatar comprises a virtual limb corresponding to the limb that is injured; and sending the base video signal to the head mounted display for visualization. The method further comprises in response to a trigger signal from the subject, sending an exercise video signal representing the avatar in the virtual reality performing an exercise to start the visual rendering of the exercise in the head mounted display, even though the corresponding real limb is substantially immobile and provides no input at all. Such exercise is aimed at rehabilitation of the limb from the injury with the virtual limb corresponding to the immobile limb and it is displayed taking into account the orientation of the head mounted display. A computer program and computing systems for providing a treatment session for motor training are also disclosed.
