Kinect-based gesture recognition system enables surface interaction

Engineers at Purdue University (West Lafayette, IN, USA) have developed a system that allows individuals to interact with programs on a computer screen projected onto surfaces such as tables or walls.

Engineers at Purdue University (West Lafayette, IN, USA) have developed a system that allows individuals to interact with programs on a computer screen projected onto surfaces such as tables or walls.

The system, which employs a Microsoft Kinect sensor, identifies the fingers of a person's hand while touching any plain surface. It also recognizes hand posture and gestures, revealing individual users by their unique traits.

What is more, it allows more than one person to use a surface at the same time and enables people to use both hands, as it can distinguish between the right and left hand.

Research indicates the system is 98 percent accurate in determining hand posture, which is critical to recognizing gestures and carrying out commands.

The technology has many possible applications, said Karthik Ramani, Purdue's Donald W. Feddersen Professor of Mechanical Engineering.

"Basically, it might be used for any interior surface to interact virtually with a computer," he says. "You could use it for living environments, to turn appliances on, in a design studio to work on a concept or in a laboratory, where a student and instructor interact."

The researchers detailed the design of the system in a research paper that was presented during the Association for Computing Machinery Symposium on User Interface Software and Technology (ACM UIST 2012) in Cambridge, MA. Patents are pending on the concept.
