Touch introduces physicality to designs that were once strictly virtual, and puts forth a new test: How does this design feel in the hand? Josh Clark’s new book, “Designing For Touch,” guides designers through this new touchscreen frontier, and is the launchpad for today’s Big Web Show discussion between author Clark and host Jeffrey Zeldman.

In a fast-paced, freewheeling conversation, Josh and Jeffrey discuss why game designers are some of our most talented and inspiring interaction designers; the economy of motion; perceptions of value when viewing objects on touchscreen versus desktop computer; teaching digital designers to think like industrial designers (and vice-versa); long press versus force touch; how and when to make gestures discoverable; and much more.
