Alexis P : Thoughts and Beliefs on the Prototypes

In my opinion, I believe that the last revised prototype design is more or less the ideal one. Making the design as simple as possible would attract a larger number of children. A simpler design would be to create a mechanism to automatically switch off the pen if is not used over a small period of time. For example, if the pen has not detected any ballpoint movement for 10 minutes, then switch off. With this mechanism we can change the button principle. The button will not have to be pressed for a few seconds for switching on/off. Instead if the button is pressed the pen will switch on (if it was off) or else will trigger the handwriting task. Such alteration would not only reduce the complexity of the pen, but could also save battery energy because sometimes children will forget to switch off the pen manually. So I think its best that the switching off is always done automatically.

As Christos suggested on Achilleas' idea, changing the difficulty level should be done on a computer used only by adults, as chilren would probably overestimate their skills after completing a few easy handwriting challenges. In addition, the bluetooth and/or wi-fi chip should be used for downloading/updating not only dictionaries, but as well animations and tunes used for rewarding the child after achieving the correct hardwriting. The reason is that after several uses of the product, the kid may not feel rewarded by seeing the same animation or hearing the same tune over and over again. So to conclude, such alteration could expand our product's life.
