Your customer has five senses and a small universe of devices. Why aren't you designing for all of them? Go beyond screens, keyboards, and touchscreens by letting your customer's humanity drive the experience--not a specific device or input type. Learn the techniques you'll need to build fluid, adaptive experiences for multiple inputs, multiple outputs, and multiple devices. The future is multimodal because we are multimodal. Here is an essential guide to unleashing the potential within that symmetry. --—Bill Buxton, Partner Researcher at Microsoft Research and author of Sketching User Experiences This book harnesses our very selfish desire to make cool things into the ability to benefit clients, stakeholders, customers, and society itself. Chock-full of insightful conceptual models and practical applications, designers will be both inspired and prepared. --—Sam Ladner, PhD, author of Practical Ethnography: A Guide to Doing Ethnography in the Private Sector and Mixed Methods: A Short Guide to Applied Mixed Methods A must-read for anyone wanting to understand the richness and complexity of how users move fluidly between different forms of input, and how to ethically elevate that experience.
