"Google Glass may allow users to do amazing things, but it does not abolish the limits on the human ability to pay attention. Intuitions about attention lead to wrong assumptions about what we’re likely to see; we are especially unaware of how completely our attention can be absorbed by the continual availability of compelling and useful information. Only by understanding the science of attention and the limits of the human mind and brain can we design new interfaces that are both revolutionary and safe."
