Three virtual environments were designed for the recovery of personal, home and out-of-home autonomy in upper limb rehabilitation treatments. In particular, for the recovery of personal autonomy, the environment that was created consists of a virtual bathroom in which the patient is guided to perform the activity of brushing his teeth. For the recovery of home autonomy the environment that was realised consists of a virtual kitchen in which the patient is guided to the preparation of different dishes.
For the recovery of extra-domestic autonomy, the environment created consists of a virtual supermarket in which the patient is guided to purchase products, starting with consulting a leaflet from which to choose the products they intend to buy, thus making a shopping list, going to the supermarket with a sufficient amount of money, selecting the products from the various supermarket shelves until payment at the till after selecting the money from their wallet and checking any change returned.
Each phase of the rehabilitation exercise is assigned a point so that the final score corresponds to the sum of the correctly completed phases. In addition, at each stage of the exercises, the patient can benefit from visual aids (e.g. virtual illumination of the door that should be opened to take the ingredient needed for the recipe), vocal aids (whereby the next action to be performed is indicated by a voice) or intervention aids for moving on to the next action if it cannot be performed. In all these cases of aid requests, the setting can be changed by the therapist in real time.
Any aids requested are finally stored in the final report of the individual rehabilitation exercise, so that they can also be compared in order to assess progress in the recovery of autonomy.
