The upper
navigation schematic illustrates the layout of the fourth and final prototype, and the nether is very similar to the third we developed after having finished the
extreme and
usual prototypes. We erased quite a lot of functionalities when developing tour final prototype as we felt the former ones were't very focused on the
accessability problems for our target group in the museum exhibition we really were aiming to address. The final prototype is much clearer in what it aims to do and is much easier to use for our
target group.
