DLR (Daily Living Related)

A device based on the realisation of different virtual environments in which the subject’s movements are detected by an infrared camera and a processing software converts the patient’s gestural recognition into the activities necessary to carry out the exercises in the different virtual environments that are displayed on a monitor placed in front of the patient. Three virtual environments have been designed for the recovery of personal, home and out of home autonomies in the rehabilitation treatments of the upper limb. In particular, the environment that was created to recover personal autonomy consists of a virtual bathroom in which the patient is guided while brushing his or her teeth. The environment that was created to recover autonomy at home consists of a virtual kitchen in which the patient is guided while cooking various food.  The environment that was created to recover autonomy out of home consists of a virtual supermarket where the patient is guided while buying products, starting from consulting a flyer to choose the products to buy, thus creating a shopping list, going to the supermarket with a sufficient amount of money, selecting the products from the various supermarket shelves until paying at the cash desk after selecting the money needed for the payment and then checking that the change is right. At each stage of the rehabilitation exercise, a point is assigned so the final score corresponds to the sum of the phases completed correctly. Furthermore, the patient, in each phase of these exercises, can take advantage of visual aids (for example the virtual lighting of the door that should be opened to take the ingredient that is necessary for the recipe), voice aids (for which the subsequent action to be performed is indicated by an entry) or intervention aid to move onto the next action if it is not possible to carry out. In all these cases of a request for assistance, the setting can be changed by the therapist in real time. Lastly, any assistance requested is stored in the final progress report of the individual rehabilitation exercise, thus it can also be compared to assess the progress in the recovery of autonomy
