Summary
There has never been a better time to design conversational UIs! In this informal session followed by extensive Q&A, Greg Nudelman, the author of 5 UX design books, veteran presenter, and designer of conversational UIs on 5 different projects in a variety of industries discussed key aspects of the conversational bot experience and conversational UI best practices. Participants learned: how to pick the right bot framework, how to use basic building blocks of bot dialog (Intents, Entities, Dialogs) to create conversational UIs, and the key importance of context and channels (Mobile, Wearables, etc.) for shaping the conversational experience. We spent the bulk of time on what is "right around the bend" in the near-future of conversational UIs. From practical tips you can put to work immediately, to inspiration for your next project, participants came away saying "Bot Future so Bright, Gotta Wear Ear-Muffs!"

Notable Quotes
"Bots are not alive, so don’t name them Bob because that sets unrealistic expectations."
"You should design from zero assuming your bot is going to fail and doesn’t understand everything."
"Don’t pretend your bot has feelings unless you truly build that capability."
"It shouldn’t take more than a few hours to build a simple bot to explore what the technology can do."
"Handling pauses and timing in voice interfaces requires careful use of SSML to control cadence and breaks."
"The biggest challenge is keeping context between user interactions; humans do it naturally, bots don’t yet."
"A perfect use case can still fail if users don’t trust or see time savings from the bot."
"You can use bots to augment existing forms, for example, pre-filling a form after voice input for confirmation."
"Privacy best practices include not listening continuously until a wake word is detected and limiting data sent to servers."
