Homes are becoming more wired and connected with the proliferation of computing devices such as desktops, tablets, entertainment systems, and portable communication devices.  As computing devices evolve, many different ways have been introduced to allow users to interact with these devices, such as through mechanical means (e.g., keyboards, mice, etc.),  touch screens, motion, and gesture.  Another way to interact with computing devices is through a user speaking to a device and the device outputting audio to the user in return.  However, in some instances, certain content is best output in a form other than audio alone.
