Atouch of class

摘要

We are surrounded by electronic machines, many of which have advanced at an astonishing rate. But, arguably, the way we interact with these machines has lagged far behind. For example, decades after speech recognition was invented, how many people do you heartalking to their pcs? The humble keyboard and mouse remain the dominant interface. But things are improving. For example, the latest iPhone features Siri, a natural language user interface that answers questions and perform actions. Smartphones and tablet computers already use the touchscreen interface to great effect and if some of the many research projects underway succeed, touch technology - or haptics - will transform the way we use electronic devices.
