Keyboards vs. Brain-Computer Interfaces

Hi! Today we’re going to be comparing the usability of various household devices (Microwave, TV remote, keyboard, etc.) against those of research devices (like eye trackers and brain-computer interfaces).

Information Transfer Rate and Bits/Min

To do this, we’ll be investigating each device’s information transfer rate (ITR), or how fast the user can communicate with the device. We have some intuitive sense of this — obviously the keyboard allows for faster and more varied input than the TV remote. It’d be easy to…
