Touch is slick and easy but it’s not for everything. And it’s already going out of style. The new kid in town is a natural user interface, Post-Touch – an interface that goes past the requirement of touch and can detect gesture usually through a near-field depth camera.
With the inspiring Olympic displays of the power and grace of the human body all around us, it seems sad that we confine the human body that is capable of so much strength, agility and power, to interfaces that involve the user of just one finger. In designing interfaces, we need to look at the actual task at hand and design the best interface for it, not just the best touchscreen interface.
