The three difference virtual environments used for the trial. A. Empty room – A simple environment that represents the haptic interface workspace and aims to provide early post-stroke subjects with awareness of physical space and movement. B. Real room – An environment that resembles what the patient sees on the table in the real world. The mat with 4 different shapes on the table (as seen in Figure 1) is represented in the 3D graphical environment. This environment was developed to help discriminating the third dimension that is represented on the Monitor 2D screen. C. Detail room – A high detail 3D environment of a room comprising of a table, several objects (a book, can of soft drink), portrait of a baby, window, curtains, etc.
