Samsung and Reactrix are moving beyond touch screens and trying to make hand waving the next big computer interface.

This amazing 573 Samsung LCD TV will have a camera embedded within the unit and will reach audiences as far away from the screen as 15 feet. This standalone unit will allow Reactrix to deploy these interactive digital signs anywhere and everywhere.

"Reactrix and Softkinetic systems differ from the PlayStation Eye, however, in that they record 3-D information as opposed to just two-dimensional information."

Using computer vision algorithms to make sense of my movements is really interactive, and recording 3D information such as body motion, gestures, and distance from the screen is really amazing.

Reactrix uses an infrared light projection with a stereoscopic camera for gaining accuracy in poor lighting conditions. With the present Digital Signage Audience Measurement systems lighting is an issue, in order to properly identify an impression there needs to be a certain amount light within the camera's range. This is why Audience Measurement deployments are generally indoors where there is sufficient lighting, or outdoors with a small screen size that has enough light source to illuminate passer-by face impressions. Maybe the Audience Measurement guys should try using a similar technology to increase accuracy of their systems in poor lighting conditions.

Audience information is very much needed, with the Reactrix system it takes it a tad further by using a processor to analyze audience data to provide interactivity. This technology is similar to Audience Measurement tools for Digital Signage, because it takes data from the audience and processes it. Some people may say that only infrared images are being processed, yes it might as well be, but the system still has the ability to record regular images. The point I'd like to make, we need to have a standard with respect to privacy and capturing audience data.
