Final Design Analysis

Finally we are able to present our final design. The final design had many changes from the previous design (prototype 2) the feedback gained from personas and testing has enabled us to make the following changes

The Removal of the sliding touch pad has enabled us to change the design. The pad was removed because of perosna 2 accidentally breaking the pad. The pad was weak in design and not as secure as the rest of the features it could not survive the small knock abouts that are given to it by kids. Under careful consideration it was decided best that we do not adapt the sliding touch pad component this has enabled us to change the design and make the shape look and fell allot better than the previous prototype 2.

The USB and memory slot ports have been removed from the bottom of the panel and put on the right hand side of the panel this has made it easier for persona 5 whom complained about the wires affecting his performance and disliking the product because of this

The buttons have been changed the wireless on and off button has been added to let the user choose when to he uses the wireless and when not this was mainly done to avoid confusion with the on and off button and to save power.

The final design has been made waterproof persona 4 managed to wet the screen and it was not the best outcome the device started to have unimaginable outcomes, however this has now been amended and the device is not only waterproof but is shatterproof also

The screen has been enlarged due to the layout being changed which has enabled us to make the keyboard 1 cm bigger than before this was mainly done on the outcome of the results from the prototype questionnaire.
