Think about how user interaction is changing in todays technology. Although most users consider the GUI to be the standard interface, both software and hardware developers are experimenting with other ways for us to interact with our devices, including voice commands (like Siri and Alexa) and gestures (like Samsung smart TVs and mobile devices).

Imagine you were blind and unable to see the GUI. How would you go about designing a method to navigate through the menus? Investigate the current voice- or gesture-interface systems. Do you think they work well? What improvements can you suggest for how users with or without visual impairments interact with their devices?
