Hi Ahsley, That's a great question! I would say: - Integrating the device with other devices that the blind use on a daily basis. - Would users prefer a modular system that they can pick and choose features and assemble into one, or they would like an all-in-one device so they can have freedom of choice to pick and choose which inputs and outputs they feel comfortable using at a point of time. The initial thought behind an all-in-one from my perspective, as the designer, was to give the freedom and the breadth of ability to the users to learn, pick and choose what they want. It's how tablets work; for example, you can choose a keyboard, or mark an interface with your fingers. I would love to learn from the users, in the long run, how they would benefit from this freedom.
