Gestural interfaces

Writing for Wired, Olivia Solon describes a new algorithm that can identify human action in video. “The activity-recognising algorithm is faster than previous versions and is able to make good guesses at partially completed actions, meaning it can handle streaming video,” Solon writes. 

Jon Gold reports on how MIT researchers have developed an algorithm that can identify human activity from video input. “The researchers drew on natural language processing techniques,” Gold writes, “to create a 'grammar' for each action they wanted the system to recognize.”
